Botanical name: Wisteria

Plant type: Shrub

USDA Hardiness Zones: 4, 5, 6, 7, 8, 9

Sun exposure: Full Sun, Part Sun

Flower color: Red, Blue, Purple, White

Bloom time: Spring

If your garden is an outdoor room, wisteria provides the drapery and slipcover—to camouflage a view or provide living shade over porch and pergola.

Something between a vine and a shrub, wisteria blooms vigorously in spring with showy, cascading flower clusters that provide quick-growing color.

However, note that it can take a good six years for a newly established wisteria to start flowering—sometimes longer!

The vine may grow 10 feet or more in one year! This gives the artful gardener a paintbrush with which to cover the landscape-canvas.  Wisteria is also beautifully fragrant providing a feast for the senses.

Note: Some types of wisteria are considered invasive pests; check with your local cooperative extension. All parts of this plant, especially the seeds, are poisonous.

Planting

  • Grow in fertile, moist but well-drained soil. 
  • Ensure placement has full Sun.  Though wisteria will grow in partial shade, it probably won't flower. Sun is essential.
  • If your soil is in poor condition, add compost; otherwise, wisteria will grow in most soils.
  • Plant in the spring or fall.
  • Dig a hole as deep as the root ball and 2 to 3 times as wide. Space plants 10 to 15 feet apart.
  • Choose a site that will not overwhelm nearby plants as wisteria grows quickly and can overtake other plants.

Care

  • Each spring, apply a layer of compost under the plant and a 2-inch layer of mulch to retain moisture and control weeds.
  • Some gardeners swear by phosphorus to aide flowering. Scratch a couple of cups of bone meal into the soil in the spring and then add some rock phosphate in the Fall.
  • Water your plants if you receive less than one inch of rain each week. (To know how much rain you are getting, you can place an empty tuna can outside and measure the depth of water with a measuring stick.)

Pruning Wisteria

  • Pruning is the secret to good flowering.
  • Prune wisteria in late winter. Remove at least half of the prior year's growth, leaving just a few buds per stem.
  • If you want a more formal appearance, prune again during summer after traditional flowering.
  • For more blooms, try cutting back the rampant shoots every two weeks during the summer.
  • Do you have a new wisteria? Cut the vine back severely right after planting. Then, the next year, cut the main stem or stems back to 3 feet of the previous season's growth. Once the framework is full size, shorten further extension growth in midsummer to where growth began for that season.
  • Informally grown, mature plants need little or no subsequent pruning.
  • For a formally trained plant, cut side shoots back to 6 inches in summer, then shorten them again in winter to 3 buds.
  • Wisteria will resprout with vigor if cut back severely, but this pruning should be avoided, if possible, because new shoots may take some years before they flower.

Pests

  • Dieback, crown gall, leaf spots, virus diseases, Japanese beetle, aphids, leaf miners, scale insects, and mealybugs can be problems.

Recommended Varieties

W. floribunda (Zones 5 to 9) of Japanese origin, is capable of growing 30 to 60 feet (and beyond in the South).

  • 'Honbeni' (syn. 'Honko') is one of our favorites, bearing clusters of pink flowers in late spring.
  • 'Alba' (syn. 'Shiro Noda') bears lovely clusters of pure-white clusters; it blooms in late spring.

W. macrostachya (Zones 4 to 9) or Kentucky wistera is a late-season bloomer. It climbs to about 25 feet.

  • 'Blue Moon' is an extra-hardy wisteria with silvery-blue clusters and blooms in late spring and often again in the summer.

Wit & Wisdom

Wisteria still not blooming? Some readers have sworn by this method: Take a shovel and drive it eight to ten inches into the ground about a foot and a half out from the trunk to slice into some of the roots. Damage about 1/2 of the roots and the bush will be shocked into reproduction. It is very difficult to hurt this rampantly-growing, unrestrained, often invasive plant.

To control the roots you need

By Almanac Staff on August 29

To control the roots you need plant the wisteria in a big (at least 5 gallons) container (concrete is best) and then dig a hole and plant the container with the plant in the ground. You also have to prune the wisteria every year to control the top growth.

By Almanac Staff on August 6

Hi P.J.
You can grow a wisteria in a big container. Just make sure to prune and train it to one stem. If you live in a cold region you need to protect the roots in the winter. You can put the container in a big box and fill the box with newspapers or an old blanket wrapped around the pot. You can also cover the pot with raked leaves.
Good luck!

HI I just bought a 3' aunt

By kbashmann

HI I just bought a 3' aunt dee wisteria.I wanted to train it to go along my front porch. It was all bundled together with ties. There seems to be about 1.5" thick dark trunk consisting of a couple of branches twisted around a stake. That trunk stops at around 2'. So there is about another 1.5' of twisted green stems and leaves on top of the "trunk". THis whole thing is twisted around the stake. I have a small trellis that i attached to one of the post of the porch in order to have it climb up. What do I do? DO i untwist it and prune it? or to i just leave it next to the trellis? Or do i take the stake out? I have no idea what to do? Thanks!

I have planted wisteria this

By Simonlux

I have planted wisteria this year and it seems to have taken well. I have read a lot on how to prune so that you have 6 leaves left on any growth to encourage flowering next year. Do I cut back the new branches that I would actually like to keep as well or does the pruning only apply to side shoots and branches you don't want any longer?

Yes, it's fine to prune the

By Almanac Staff

Yes, it's fine to prune the head above 6 leaves -- cut off any shoots that aren't needed to extended the head. Do this in August. Also, you'll want to prune any sideshoots this winter (February) down to 6 inches to 1 foot. Every winter, cut back the shoots again to an inch as part of normal pruning.

I have planted a wisteria in both my front and back yards. Both have great growth, but no flowers. The plant in the back, the tendrils wilt and I pinch them off. Help!!

There are many reasons

By Almanac Staff

There are many reasons wisteria plants don't bloom--some discussed on this page. The main reason is usually lack of sunlight. Also, know that wisteria grown from seed will not flower for about 7 to 10 years. A third reason is related to pruning. See this page for pruning advice. if your pruning is appropriate, try applying phosphate fertilizer (with no nitrogen).

I need help for the wisteria

By Patricia Reese

I need help for the wisteria plant in front of my 107 year old house (I suspect plant is probably the same age)....
It has grown up the front side of house, and every year it sends runners that wrap themselves around my electrical and crawl under shingles on my roof! Blocks the front windows on its way up to the roof. It also has grown completely over the trellis overhead and down the gates in front, and the weight has collapsed some parts of the wooden trellis and fencing (which are also rotten/old). I cannot replace the trellis or fencing without cutting back old woody growth that has wound itself in and out of the lattice work. I would like to save the base of the plant, which is about 1.5 feet diameter or wider. I really need help!

Hello, I have had a wonderful

By Christine McCormick

Hello, I have had a wonderful white wisteria for 2 years. The trunk diameter is approx 1 1/2 ". It gave an abundance of blooms each spring before leafing out. This year it bloomed as usual, then suddenly the blossoms wilted and fell off prematurely. Then the leaf buds came out very stunted and small. It has been in this stunted state now for about 4 months. The trunk and stems seem fine, and I see no signs of insect pests. I have fertilized, pruned back, and water regularly with no success. It gets adequate sun. The roots are in a gopher cage to prevent gopher damage. We live in southern California inland. The stems are alive, but the leaves are very tiny about 1/2" and have stopped at that size. Such a mystery....any suggestions? Thank you!

By Almanac Staff

Hi, Christine, We really do not have a good answer for this, especially from a distance. Is it a grafted plant? Sometimes the plant above the graft (or below) fails. Below ground, it could have root rot.
It seems to happen occasionally as you describe, but there is no clear explanation or remedy. We suggest that you consult a local nurseryman.

By Christine McCormick

Thank you. I did consult a local nursery and he was puzzled also. There is growth at the base, so it seems as though the top part has failed for some reason. I'm trying to decide whether to take it out, but it seems such a shame to give up on such a mature and beautiful plant. I am tempted to leave it in for one more season and see if Spring brings a change. Always hopeful!

By Anonymous

I live in Iowa and have had my wisteria for like 3 years. I bought it as a plant from a nursery. Last year it grew great, about 5 feet with many side shoots. I kept cutting off the shoots from the base of the plant. My husband trimmed some of the vineing shoots back as they were getting long, but kept them like two feet long.
This year at first nothing was happening. Now after all the rain, there are shoots coming from the base. Is the main trunk/plant dead or will it come back? Should I let the new shoots keep growning or trim them back to inhibit growth from the main plant?

Hello. Touring Venice by

By Bina

Hello. Touring Venice by canal and seeing all the beautiful wisteria reminded me of my childhood where we had a fragrant wisteria bush near the back door which the dogs used to like to lie under in the heat of the summer and snap at the bumblebees.

We now live in Virginia about 35 miles further west than DC, at about 800 foot elevation. We have an inward-cutting corner of the house right outside our kitchen windows which I think would make a good spot for a wisteria tree... if. Our basement foundation is entirely underground, poured concrete reinforced with steel mesh. Would this wisteria tree likely pose a threat to our foundation? Thanks.

I planted a wisteria

By Linda625

I planted a wisteria sinensis/ Japanese wisteria 3 years ago, in full sun, and it has hardly grown. Each year around June the growth tip wilts and dries up, despite me watering it. There is then no growth for the rest of the year. The rest of the plant looks healthy, the leaves are green and they don't wilt. It's only the height of the pergola and at this rate, it's never going to make it onto the top of the pergola.

Hi, Linda: Have you been

By Almanac Staff

Hi, Linda: Have you been talking to Mother? She had the same problem two years ago! Be sure to read all of the info above about care. This could be a question of maturity (the plant of course, not you), but since it seems to be growing somewhat, perhaps it's soil conditions. Make sure that it is not getting too much nitrogen (since it is a nitrogen-fixer, this is the last thing it needs). If the soil is just plain poor, give it a dose of 5-10-10 or 10-10-10 fertilizer (as you no doubt know, the numbers stand for nitrogen-phosphorus-potassium). A continued dose of patience is needed, too, so just hang in there and your wisteria will, too -- just like Mother's!

Great site! I just planted

By Linner

Great site! I just planted several small wisteria. 2/3 are doing well & growing. The other 1...well, let's just say it's sad. The leaves are turning whitish/yellow. They have not dropped off yet, but are getting dry & look like they might. It is in well-drained soil, getting regular watering, & plenty of sunlight. Is it a pH issue...bugs...or maybe I need to add a special fertilizer? I'm in central MD. Thx so much!

Yes, wisteria always grow

By Almanac Staff

Yes, wisteria always grow seed pods after flowering. Wisteria is a legume, like peas and beans. If they bother you, you can clip them off (but not the buds). Or, you can let them dry and save the seeds to plant new wisteria.

I planted a wisteria last year. It had several blooms. This year I have nothing but the base of the plant. I have no green coming from the plant. I tried to dig up the plant and it appears the roots are still alive. Tons of roots. Does this mean the plant is dead? Any suggestion on what I should do?

By Almanac Staff

Hi Laurie,
If you don't have any new growth on the plant it is probably dead. You can leave it in the ground and see if by a chance it will show any signs of life. Harsh winters can kill a young wisteria.
 

I planted two 6' tall

By Lisa Vreeland

I planted two 6' tall wisteria last year, not realizing how invasive they can be. One is planted approx 3 ft from Japanese maple next to front porch, stone steps, to grow over porch area. I am afraid it will kill the maple, dislodge steps and walkways, etc. is it possible with heavy pruning to keep the ground runners in check? Brother in law (tree guy) says it will also get into stonework and pull it apart and runners will travel to other wheeping cherries and trees and invade them. I believe it is Chinese variety. Should I take them out? Love this site and thanks for the info,

Wisteria can be controlled by

By Almanac Staff

Wisteria can be controlled by heavy pruning but its root system will also grow rapidly and new plants will grow from dropped seeds. It is a very invasive plant. We suggest that you move the wisteria to an area away from your house and other trees. You can plant other climbing vines close to the house that are not invasive. For example native honeysuckle, Lonicera sempervirens, is available in yellow and red cultivars.

Three weeks ago I had 2

By Stefanie

Three weeks ago I had 2 wisteria's planted next to a trellis. They were doing beautiful. One day I came home and one of the vines the leaves were brown and spotted. I went to the nursery and I took some leaves with me. The nursery worker told me it was a fungus. I bought the spray and sprayed it. Now my other wisteria is in very sad shape. The leaves are all dried up and twisted. I water every day the amount the nursery told me to. What can be the problem?

Hi, Stefanie, Your nurseryman

By Almanac Staff

Hi, Stefanie, Your nurseryman was probably in a better position to tell you what the problem is, having seen the evidence. Since he said it's a fungus, it may be a "honey fungus" a common name for several different species of fungi that occur in woody and perennial plants. The most obvious sign is white growth between the bark and wood at ground level. Honey-colored mushrooms nearby pretty much confirm the presence.
It could be powdery mildew. That's indicated by irregular dark brown marks and blotches, usually with a yellow margin.
It could be a vein virus. That will appear as spotted, shriveled leaves.
As strong as many wisteria appear to be, they are vulnerable to many problems. We can only suggest that you continue the recommended treatment.

By Linda Kitts

I also have a wisteria planted next to my privacy fence. I wish I had planted it in the center of the yard. If you don't cut the vines that grow between the slats in the privacy fence they will grow and separate the fence. It's better to have chain link or some type of metal they can grow on. I'm seriously thinking of cutting it completely down.

Hi, Avis, The recommended

By Almanac Staff

Hi, Avis, The recommended spacing is 2 to 3 feet apart. The vines will twine—around themselves and eventually around your fence. If you want to guide them, use string, loosely tied. The 4-inch span is a little wide but with time (and maybe a little help), the vines will find it and them wrap around it—and additional vines will wrap around the original ones.

I just planted a new

By Meri Ford

I just planted a new wisteria. IT seems to have multiple main stems that want to twine around each other. Should I let them twine around each other and support them from the arbor post or let them twine around the arbor post itself? We got it last summer but didn't get an arbor built and did no pruning of the growth last year.

Hi, Meri, Your wisteria will

By Almanac Staff

Hi, Meri,
Your wisteria will twine (and twine and twine) on the nearest thing/s, including itself (not such a bad thing; this could strengthen the trunk over time). If they don't find the arbor soon, guide them to it with lose ties (string will do; you can cut it off later). Wisteria LOVE to twine and climb. We know of one shoot went about 20 feet under the aluminum siding on a house before it was discovered. Fortunately, because it received no light—but heat!—under there, it was a weak vine and could be pulled (and pulled and pulled) out.

I found about a dozen bulb

By IamDebbie

I found about a dozen bulb type things on top of the ground, scattered underneath my wisteria. They are whiteish in color, 1/2" to 1 1/2" in size, and have an outer skin which is peeling in areas. The larger ones are beefy/ripe looking and resemble a fresh fig in consistency, except for the color. Do the wisteria seeds grow into bulbs before they sprout, or are they some other kind of plant. My wisteria trunk is about 6". I have never seen these bulbs underneath the plant before. Please advise what you think they may be. They are definitely a bulb (not a mushroom).

Wisteria seeds don't turn

By Almanac Staff

Wisteria seeds don't turn into bulbs. If you think they are bulbs plant a few in a container and see what will grow or bring one to a local garden center to see if they can help you identify it.

By Almanac Staff

Hi Gloria,
It's important to prune old wisterias. Prune the out of control vine as close to the main stem as possible. You can also dig down and cut part of the root that the vine is attached to. Your wisteria is well established and moderate to heavy pruning will not hurt it.

I have a 10 year old wisteria

By Diane romaine

I have a 10 year old wisteria with a one foot diameter trunk growing on to a pergola where it has been happy and thriving in direct sun. I have never prunned it because the pergola is @30ft long and it has taken some time to gorow almost all the way across the span. I live in Western Maryland at an elevation of 3000 ft and the spring was very cold. Now I have neither blooms nor leaves. The stems seem to be green not dead. Being that it is late May, is it too early to cut it back? Should I stress the roots with the shovel to wake it up as you say? OR should I wait a while longer?

Wisteria have been known to

By Almanac Staff

Wisteria have been known to "sleep" for years (est 12 to 15), so it may be entering such a period. You can't know now. Pruning, even a little each year—in spring—can help to promote flowering, but too much pruning can have the same effect (although that's not your problem).
Did you fertilize it? Excess nitrogen fertilizer can cause few/no blooms. Another source suggests that it may be going through a growth spurt instead of flowering.
An extreme cold may have killed the buds.
You can try to "wake it up" with a shovel. However, because flower buds form in late summer, understand that it will not flower this year.
Good luck—

HELP!!! I have a beautiful,

By Anna Zin

HELP!!! I have a beautiful, mature wisteria plant with about a one foot diameter twisted trunk climbing across my pergola at my house in central Italy. Last year, it bloomed profusely and had leaf coverage all summer.
My neighbors gave it a good pruning this winter without asking us. In addition, we had another wisteria plant removed on the opposite side of the pergola last spring because it had dried up and was dead. Now, despite wisteria blooming all over town, my plant remains brown without leaves or blooms and it showing no signs of life.
I am heart sick. Is it dead? I am currently in Canada but will be going to Italy in two weeks. I'll do whatever it takes to bring it back to life. Please advise.
Thank you so much

A "good pruning" is

By Almanac Staff

A "good pruning" is impossible for us to define. Pruning wisteria can promote flowering. However, the time to prune is after it flowers. The plant sets buds in late summer to fall.
If it was severely pruned, it may need time to adjust and start growing again.

Hello, I would not fertilize it at all. I have several wisteria some as vines growing over a pergola and several trees. When I first moved here over 11 years ago I had one huge wisteria it bloomed from top to bottom completely over a building we have. I wanted it to do the same the following year so I fertilized it. I didn't have 1 bloom. I have grown them now from seed and I never fertilize and always have blooms but never have a bloom if they were fertilized.

Same here with 2 wisterias

By laurel

Same here with 2 wisterias and a weeping cherry. Everything else has blossoms and leaves.. Im in NW PA and feel your pain. We have no idea what happened

Did you have a sharp spring

By Almanac Staff

Did you have a sharp spring frost this year? Many regions experience very cold springs. This could have caused the flower buds to drop before even opening. One way to aide a wisteria is to ensure the soil doesn't get depleted of its nutrients and it has adequate levels of potassium; on poor soils, add sulphate of potash in spring. Finally, pruning can be a culprit. If you prunedly heavily or in early summer, it could have disrupted flowering. However, timely pruning can help to increase the flowering. DO not despair. Wisteria can be very tough and return next year.

Hi, I have an east-facing

By JenW

Hi, I have an east-facing balcony in NYC and planted a baby blue moon wisteria (only about a foot tall, purchased from Jackson & Perkins) in a larger, well-draining pot when I received it two weeks ago...but I'm already noticing brown spots overtaking one of the leaves and slight curling on a couple others. I'm reading that they need a lot of sun, and my balcony gets only 6 hours daily right now. Might that be causing the browning and curling? The left side of the balcony gets sun for a tad longer...would it be helpful to move it there? Or should I just start pursuing a refund from J&P? Thanks in advance for any help!

Wisteria 7 years old,

By Churyl Kylo

Wisteria 7 years old, transplanted 4 years ago and is in a sunny location but has never bloomed since just rapid growth every year. There are 5 or 6 stocks twisted together all about 1" in diameter but not one that looks like the leader. Would it be advisable to cut all the stocks except 1 or 2 down next winter or shock it by digging down to the roots 2' from the base, or just be patience.

The stalks twining together

By Almanac Staff

The stalks twining together is a natural way for the wisteria to grow a sturdy trunk--it doesn't seem to be affected by it healthwise; so, we wouldn't suggest that you prune it down to one, unless you are developing a standard wisteria tree for an accent, or are otherwise training it formally.
 
Wisteria may not bloom for a few reasons--health, weather, improper pruning, sunlight, soil nutrients, etc. The transplanting may have delayed the bloom, so you might just wait and see. It may also be that the plant is not old enough to bloom--some can take up to 15 years.
 
If you think it might be due to something else, you might try adding phosphorus. See tip under "Care" above. Avoid fertilizers high in nitrogen--the vine fixes its own nitrogen, so it doesn't need much. Too much nitrogen will promote shoot growth over flowers.
 
Wisteria needs at least 6 hours of sun to bloom, so it sounds like you now have it in a good location. Make sure it has enough water but also good drainage.
 
Pruning is another option. Before doing root pruning, you might try a routine regular pruning. Please see above article for instructions. Prune back new shoots in mid-summer (after the plant would normally have finished blooming) to about 6 to 12 inches. In winter or early spring, you can prune when it is dormant, down to about 3 or 4 buds. Avoid a drastic pruning, as this will delay potential flowers for a few years.
 
Hope this helps!

Years ago, I transplanted

By LA hoping

Years ago, I transplanted severalpeices of my mother-in-laws beautiful wisteria into my yard. She had a beautiful vine with wonderful smelling blooms. I was told that the transplant might cause no blooms for up to 7 years. Well we are now way past that point, and all the transplanted vines became beautiful trees, never to bloom. Is there any hope for these full grown trees to ever bloom. Mom is gone now, and we will never part with the trees, but wonder if there is any hope for a future bloom. Plus why did our vine transplant become a tree? Sad at heart.

I live way down south in LA on the water - hot humid. I just purchased a Wisteria plant I would love to keep in a large pot. But I see they are susceptable to mealy bugs. I hate mealy bugs. I can't grow Hibiscus bushes because they get infested with mealy bugs and nothing stops them. Is it possible I could have the same problem with this Wisteria?

Hi Kelly,
Wisteria can be grown in a container. Insert a sturdy piece of wood or bamboo about 4 feet tall for the plant to climb. Containers dry out quickly in hot weather so make sure to check the soil often and water as needed. If you get mealy bugs on the plant try insecticidal soap (it needs to be applied regularly) or horticultural oils such as sun spray or neem oil.

Well, this is the second time I've tried to post, so hopefully it will work!
I am fairly new to the gardening community and am looking for a vine/climber for the chain-link fence that borders my yard. I have had several recommendations for wisteria. I have some 4" plants on order from the Burpee website and am wondering how many Wisteria I should plant if I decide to go this route...I was thinking one in each corner of the yard. I have a fairly good-sized yard that sees sun all day in the back and most of the day (about 9am-sunset) in the front.
Any recommendations would be greatly appreciated!

It all depends on how long your fence is. You can plant one in each corner and then maybe one in the middle. Be aware that you need to train the wisteria to grow horizontally to cover the fence.

My mother grew a Wisteria started from a cutting given to her from my favorite aunt. Both are gone now and my father no longer wants the plant. He is just going to pull it out and kill it. It is about 20 years old and has a large trunk. Is there a way to successfully transplant? I know Wisteria vines are tough but this might be too much for it and I can't loose this plant. It is Spring here in Oklahoma and I have plenty of land so it can run free. I'm just wondering how much of the root ball should I leave on the plant or if there is a chance it will survive. I haven't been able to get a cutting to root and it hasn't produced seeds in years. Help. It's days are numbered!

Replant at the same depth, with the same sunlight orientation. Water to soak the roots, and water every week until it gets established. Do not expect flowers for a couple or a few years.
 

When we bought our 140 yr old

By Amber Henderson

When we bought our 140 yr old home in the Central Coast area of California last October, we had to have it tented for termites. The large pergola attached to our home was tented along with the house. The pergola had an enormous wisteria covering the entirety of it. The leaves withered and fell off. It is now April and while other young wisteria in town have had blooms for a month, we see no signs of life in our old tree. In hopes of increasing chances of recovery, we have begun to cut off the thick mat of vines and cut back branches to the trunk. Is there anything else we can do to save this old wisteria?

Now I have replaced the small arbor with a larger arbor but the base of the plant is about 2 ft. away from the side of the new arbor. Should I dig up the plant and replant it closer to the arbor or just train the vines from the position it is in now? Will the wisteria survive if I replant it?

Replanting it is certainly an option. Be sure to get about two-thirds of the root, and be ready to wait a year or two for it to return to normal growth. Training would appear to be an option (not knowing what else is in place or involved at your site).
Have you considered moving the large arbor closer to the plant?

I live in Texas and recently

By Atexasparker

I live in Texas and recently bought a house with a lovely old wisteria bush growing in the front yard. I was not sure what it was until it started blooming. I cut it back a small amount and it has a few blooms on it, but nothing like some of the others in the area (which have tons of blooms). It seems that I should have cut it back a bit more. Since it has started blooming, is it too late to prune it more aggressively. Should I cut it back or wait until fall?

We'd suggest that you prune

By Almanac Staff

We'd suggest that you prune your wisteria twice a year:
1) AFTER it blooms in July or August. (It sets buds in autumn for next spring's blooms.)  Just cut back the whippy green shoots of the current year's growth to the first 5 buds on the branch (starting from the base). Also, prune out any straggly, long shoots from the base of the plant that don't contribute to the framework.
2) Then, prune more severely in the winter when it's dormant.
Cut back the same stems down to 2 or 3 buds. So, you'll probably be cutting back those soots to one-third or one-half of their length.
If you didn't do the winter pruning, it should be fine to do this in the late summer, but perhaps you take it one step at a time. Of course, lots of bright sun is also needed for flowering so make sure your wisteria is not in shade.

My house was destroyed in the Okla. tornado last year and my two large wisterias that were on my arbor were severely damaged. In order to remove the debris, they were cut and are now about 5' high. The problem is the tornado moved them backward in the ground and they are not upright. I'm not sure whether to force them back upright, my husband tried with one and there was a cracking noise, or what to do. Do I cut them down completely and start over or try to move them back upright and possibly break them?

Hi Ann,
It's not good to force them back upright. Instead tie a heavy rope around the trunk and anchor it in the direction you wish the tree to go. Use a piece of garden hose around the rope where it touches the tree to protect it. Tighten the rope a little every few weeks to pull it back upright.

Perennials that grow well

By Tammy Hyland

Perennials that grow well with Wisteria? We have 3 Wisteria vines that were planted about 6 years ago. They bloom nicely, each on one corner of our pergola. They are planted in a flower bed that used to grow Black Eyed Susans. I noticed over the last couple of years that the Black Eyed Susans appeared to be dying. They looked so bad last year, I dug them all up. Are there any perennials that can share space with Wisteria vines, or does the Wisteria basically choke everything else around it? If perennials won't survive, can I plant annuals in the flower bed? I also noticed the 2 clematis vines that were climbing a couple of the pergola beams are also no longer alive.

By Almanac Staff

This is a common problem. It is the nature of the plant to send up shoots after a few years of apparent controlled growth. The best solution that we know is to use the "cut stump" treatment: Cut the shoot stem, or trunk, close to the ground and as level as possible. Then, immediately paint on a herbicide that contains triclopyr. (Do not do this in rain or when rain is forecast.) Consult a nursery for a product; most are known as stump or bruch killers.
BTW, this same process is recommended for eliminating the mother plant, or main stem. Be aware that as long as you have the main plant, you will probably continue to see shoots both near and far from it.

I live in Michigan and last night we had a terrible wind and rain storm. The wind knocked down the trellis I have my wisteria on causing the base of the trunk to split. What can I do to save the plant?

Because it's hard to advise

By Almanac Staff

Because it's hard to advise without seeing the actual damage, for best advice, we'd recommend talking to a horticulturist who can examine the plant.
 
In general, wisterias can usually survive being pruned almost to the ground. As long as the roots are intact, they should send up shoots next season; it may take a few years, however, for the vine to bloom again. If you want to use this method, cut below the area of trunk damage.
 
If you want to try to save the main trunk of the vine, success will depend on how much damage the plant has sustained. In certain cases, the damaged trunk can be wrapped temporarily with special material for this purpose to help it to heal. Also, certain supports might be needed. A horticulturist would know the best method for your situation, and how to help prevent insects and diseases from entering the wound.
 
To alleviate plant stress, keep the plant watered (a normal amount) for the rest of the autumn. Provide some winter protection, such as about 6 inches of mulch and a windbreak. Remove them in spring as temperatures warm.

I live in Wisconsin, just moved onto a house at the end of July that we found out has a wisteria plant growing on the backside of the house (facing south), according to the neighbor it blooms well. I'm wondering how I should best care for it. The house was vacant for over a year and if it was on a trellis it was removed (it appears a little over grown and strangling other plants). Should I put in a trellis? If so how tall? When and how should I prune it? Should I instead consider moving the plant to another location? Any other considerations? Please keep in mind I'm an amateur with a black thumb. Thankyou!

Hi, Jenny, You'll need to

By Almanac Staff

Hi, Jenny, You'll need to prune the wisteria. In late winter (Jan/Feb), cut the shoots back to about 3 buds from the base to create short, flowering spurs. Remove long shoots from the base of the plants.
Ideally, you'll prune twice a year--down to 6 buds in August and down to 3 buds in late winter.
Training against a south-facing wall is perfect for wisteria. Support can be provided with an espalier--with horizontal support wires (3mm galvanised steel) set one foot apart.

By Almanac Staff

Wisteria can survive severe pruning once it's established as it's quite vigorous. We're not clear what type of wisteria you have, but be aware that the lovely wisteria common throughout the Southeast is actually an invasive. It should not be grown in between properties as it will grow very rapidly, shade other plants, and even kill trees if allowed to grow unchecked. The less common American wisteria is not invasive, and can be found through some nurseries, although it is not as fragrant.

Hi, Debbie, It is a very good idea to "winter-proof" your winteria in Canada. Here are a few tips:  1. Provide plenty of water in the autumn for its roots. 2. Add a deep layer of organic mulch for the winter (about 15 cm deep) to insulate the plant. 3. Consider building a temporary shelter to shelter your wisteria. Put 4 stakes around the wisteria and wrap a frost blanket around them; fill with dried leaves. If the wisteria was downwind of an evergreen windbreak, that would protect it, too.

Wisteria grows best if

By Almanac Staff

Wisteria grows best if planted in the ground, and adapts well to a sturdy fence in full or part sun. But, it can be grown in a planter, too. Plant the wisteria vine in a container that’s 2 to 4 times the size of the one it originally came in. Water and feed regularly. The vine needs to be pruned to a manageable size when it starts growing and you may need to transplant it to a larger pot later in the year.
 
Please be aware that all parts of wisteria, especially the seeds, are poisonous to cats, dogs, and other animals if ingested. It is also dangerous for children, who are sometimes tempted by the seeds; just two seeds may cause serious illness. In adults, mild to severe digestive distress may occur.

Being all part of the same genus, all wisteria flowers will have a similar structure. However, between the different species and cultivars, there will also be differences, such as color, fragrance intensity, flower cluster length, size of individual flowers, bloom time, whether all the flowers in a cluster open at about the same time or individuals at one end of the cluster open first; etc. When purchasing a wisteria, check out mailorder catalog descriptions, or ask a local nursery about the different varieties availalble.

By Almanac Staff

It's hard to tell what's happening without actually seeing the plant. However, you probably need to train one of the laterals to be upright to take the place of the other. Tie one of the laterals to the vertical wire and trim off all other laterals to 2 or 3 buds. The lateral should, over time, adjust to its new upright orientation. When it reaches the desired height, stop it from growing further by keeping it trimmed to 4 or 5 buds. Next, allow a few laterals to grow horizontally, which encourages flowering. Follow yearly maintenance pruning.

To plant wisteria from seed, you can harvest the dried pods from a plant, remove the seeds, and soak them in warm water for 24 hours. This will help them to germinate. After the soak, plant them about 1/4 inch deep in pots filled with moist potting mix. Cover pots with plastic wrap, place in direct light in a warm room. Keep the potting mix moist but not wet. Remove the plastic wrap when seedlings appear.
 
Keep in mind that plants grown from seed may take 10 or more years to mature, and will not flower beforehand. (Cuttings are a much quicker way to propagate wisteria.) Also, depending on what the parent plant was, the seeds may not produce plants that look like the parent.

Yes, wisteria might first appear as a long stick! 
You are planting grafted wisteria. Just set it right into your prepared soil so the graft union is slightly below the soil surface. 
We normally plant in the spring, however, wisteria can be planted in the fall, too. 
Wisteria prefer soil that drains well—moist, not soggy or wet; start with grafted plants or those produced from cuttings rather than those grown from seed.

Brown spots can be signs of a fungal infection. Make sure it's getting enough water but also that it is watered at the soil line and the leaves aren't getting wet. If this is a fungus, you'd want to prune affected leaves and also prune the vine to help airflow. However, we'd recommend that you provide a sample to your cooperative extension service to get a diagnosis.

It's best to grow wisteria

By Almanac Staff

It's best to grow wisteria away from buildings and trees, and instead on a trellis or trained as a single-stemmed "tree" standard, because the vigorous vines can cause damage otherwise. If you set up a trellis/arbor, make sure it is extra sturdy for these heavy vines.

To rejuvenate overgrown wisteria, you can prune back hard (prune all shoots off the main trunk down to 3 or 5 buds, or instead, about 3 feet below where you want the mature length to be. Cut the main branches back to 4 to 6 feet. Remove all suckers). However, with this method you may not have blooms for a few years.

A more gradual approach is below. This method is also suggested for yearly maintenance:

1) in July or August (about 2 months after flowering is over): cut each lateral shoot down to about 5 or 6 buds, or about 1 foot in length from the main branch. Remove any suckers.

2) in January or February (when dormant): Cut each lateral shoot that had been pruned in summer down to about 2 or 3 buds. Remove suckers. Cut back any shoots that had emerged after summer pruning down to about 5 or 6 buds.

American wisteria (Wisteria

By Almanac Staff

American wisteria (Wisteria frutescens) grows as a wildflower in your area, and can grow 6 feet to 45 feet. Flower racemes can grow 2 to 10 inches long. Chinese and Japanese wisteria, which have naturalized, are both listed as a threat in South Carolina because they are invasive. There is a miniature wisteria cultivar, ‘Kofuji', thought to be a Chinese wisteria, although I don't think it would have escaped to the wild. If the plant is only in your yard, perhaps that is it, or something similar. It is often used for bonsai, growing 8 to 12-inch stems; about 2 feet wide and tall habit. Also, some wisteria varieties can be used as ground covers. Or, another possibility is that it is a wisteria-lookalike.

want wisteria to bloom

By Almanac Staff

Wisteria likes neutral to slightly acid soil (pH of 6.0 to 7.0) and full sun, in particular. Failure to bloom can be the result of too much nitrogen in the soil or even a harsh winter that kills off buds.
Some growers try root pruning to inspire buds: In summer, prune to allow only one strong leader to develop from the end of each main branch. This leader should be allowed to thrive and be attached to the support. Prune the ends of all new shoots just below (before) the sixth or seventh leaf. As new shoots develop, remove them as soon as one or two leaves develop. Then, in late fall, use a spade to cut vertically into the soil (about 18 inches deep) and about 4 feet away from the main truck in a circle around the trunk. This, combined with summer pruning could help blooming.

You can prune drastically but be aware that you may not have blooms for a couple of years. Cut off all the sprawling branches and once the wisteria starts to regrow prune so that you have a trunk and a few main branches. Then pinch back the tips of the side shoots that start growing a few times during the summer months. Prune these shoots also in the winter leaving two or three buds on each. Good luck!

Wisteria Pruning

I have a wisteria (I think it's Chinese) that only made one bloom over the last two years. It was relocated to the spot it is in about 4 years ago and took off quite well. It gets prolific long streamers all through the growing season. Here's my question, After reading through the above Q&A's above I see conflicting info on when to prune. Some of the advice says prune in late winter when it's dormant and again after blooming while other advice contradicts this and says never prune while dormant but that late summer or late fall is best to prune. I am confused and would appreciate some clarity. It is mid February and I live in British Columbia in the Okanagan Valley, should I be pruning now or not. I would like to encourage better form and would really like to have flowers at some point. Right now the vine has 2 stalks that are about 2" thick and about 20 that are 1" thick or less. The vine has never been trained but is rather draped over a chain link fence. I would like to remedy that and train it up as a screen.

It is best to prune wisteria right after it has flowered in mid-summer so that you don't prune off future flowering buds and lose next year's flowering display.

But be aware that you will remove some of the new flower buds that have already formed.

Wisteria is a hardy vine and can take a lot of abuse. The roots are probably still OK. Hopefully you'll see new shoots this spring.

I just wanted to let you know that I came to this site looking for information on growing wisteria. However, I was immediately hit with a pop-up ad that could not be closed; I was forced to "shop now." I do not patronize websites that use strong-arm tactics in their advertising.

did i kill my wisteria??

By Anonymous

I got my wisteria about 6 months ago. When I got it, it was full with green leaves, and blooming. After I got it home, it started to wither down to literally just sticks. The leaves had started turning yellowish green, and dried out turning upward. Then they all just fell off. And i ha ent seen anything yet. It did bud but nothing more, they just whitheted down too. It's been watered properly, I just don't know what's wrong....

By Almanac Staff

The wisteria may have experienced transplant shock. I assume that you have it planted outside. You may still get some new growth this spring.

Im in the uk and bought a small roughly 6inch plant off ebay that arrived in december, i left it on my kitchen windowsill and just gave it a small amount of water once a week, now it has grown to about 2 feet tall. Not sure if i should have kept it outside now but need advice on what to do now.

The best time to plant

By Almanac Staff

The best time to plant container-grown varieties is in the spring. Plant in a location that receives at least six hours of sun a day.

Can I grow wisteria in snow country?

By Anonymous

I live in Elko Nevada which is considered high desert...we get snow in the winter sometimes as much as a couple of feet...our springs are cool and we have fairly short growing seasons. I love the look of this plant and really want to try growing it but I don't want to doom it from the outset. Any clue as to whether it would do well in my area?

Most wisteria varieties grow

By Almanac Staff

Most wisteria varieties grow well up to USDA zone 5. There are some cold hardy varieties that tolerate very cold winters. To protect your wisteria in the winter you can mulch it in the fall and it should come back nicely in the spring. Good luck!

Wisteria Insects - NH

This year my 3 year old wisteria plants had some sort of insect infestation. There were holes in the leaves and tons of tiny droppings under it yet I could not tell what it was. Please help. What should I do so this does not happen this Spring and what would you recommend.

Aphids and scale insects are

By Almanac Staff

Aphids and scale insects are common pests on wisteria but they usually don't chew holes into the leaves. It could have been grasshoppers munching on the leaves. You can try to spray with horticultural oils or insecticidal soap this spring.

Wisteria's toxicity

By Anonymous

We are starting a new garden after construction of our home. There is an almost dead, two-story tall tree in the yard that I considered a good support for the wisteria plant. I am concerned about the seeds,however. Will I be able to maintain this plant when mature, pruning and collecting the seed pods before they scatter? Do they burst as the fall? I have school age children and often visitors with smaller children and pets--is wisteria a good choice for me?

By Almanac Staff

Wisteria plants are a lot of work. Pruning and picking up seedpods can be a chore. The plant is toxic but only if you eat the seed pods.

runners

We had to remove the main trunk of our 10 year old wisteria when we replaced the sewer line. We now have runners growing like crazy. Will these runners produce flowers and can I twist them together to form a main trunk or should I get rid of them?

By Almanac Staff

Save a few runners and start pruning them in the spring. Don't twist them. It will take many years before these runners will bloom.

Yellowing leaves

By Anonymous

Hello, My Wisteria is very well established about 35 years old. Always blooms beautiful purple blooms. Recently like within the last 2 months I have noticed that some of the leaves are turning yellow and falling off. This huge vine is usually quite healthy this is the first time this has happened. I live in southern California is planted in full sun. Please help with any suggestions I don't want to lose this plant. I could post a picture as well if it would help.

Yellow leaves

By Almanac Staff

Thirty-five years is certainly a long time... Have you ever amended the soil? Now may be the time. Your soil may be on the alkaline side--that is, have a high pH.
Yellow leaves can be a sign of iron deficiency and you may need to add acid (via peat moss, etc.) to the soil. Remember: plants feed through their roots, so this starts at the roots.
If yellow leaves are only just now appearing, you may be able to stem/cure the deficiency.
Do a pH test (it's easy and kits are available at garden/nursery/home stores).
Spread the acidic component around the trunk and for several feet in diameter, even dig a little into the soil, and soak it well. How much? That depends on the pH test. Perform another test a few days or weeks after doing this. (Don't test the soil amendment; that will not tell you about the soil at the root.)
A severe deficiency may require more severe measures, such as drilling holes into the trunk and applying tubes with nutrients in them or drilling holes into the ground at a 45-degree angle to a depth of 12 inches 3 to 5 feet from the trunk and applying nutrients. We suggest talking with professionals before attempting these treatments. Best wishes for success!

Thank you for your response. I will try the test. I have never amended the soil. It has never had a problem so I thought to leave well enough alone. Should I amend the soil around the trunk prior to the test or test first ? Thank you for your help.

Train against a brick garage?

By Anonymous

Could we plant wisteria along the back of a brick garage? The garage faces the house but is far from it. The brick wall happens to have some metal hooks coming out it that could be used to train the vines. We want to also plant a shrub or two and perennials in the same bed. Would the roots of the wisteria be a problem?

Wisteria roots will need

By Almanac Staff

Wisteria roots will need space and will spread. Don't plant other shrubs or plants too close to the wisteria.

Wisteria

By Anonymous

How aggressive is the root system of the Wisteria? Can it be planted in Patio Pots?

wisteria roots

By Almanac Staff

Wisteria growth can be very aggressive (especially in warmer climates), with some species (such as Chinese wisteria) more vigorous than others (such as native types). If not pruned to keep them in check, these sturdy vines can damage their supports--including siding, trim, gutters, roofing, trees, and shrubs. It's best to keep them away from buildings and trees.

You can grow wisteria in large containers (such as a large half barrel) if you are willing to keep the top pruned to a size that matches the root area. Many container-grown wisterias are grown as standards. Choose a less vigorous type, such as American wisteria (Wisteria frutescens). Provide a tall, sturdy stake or other support for the plant. Make sure you have a way to transport the container easily; provide winter protection, if needed.

wisteria cut back

By Anonymous

I just planted a new Blue Moon wisteria in Iowa this spring. I'm now realizing my arbor is not going to be sturdy enough to support a mature plant. Can I cut it off of my existing arbor, or will that kill it off? If I can, can I cut it off this fall?

arbor issues

By Janice Stillman

Our experience with wisteria is that you can cut it back—almost to the ground, in fact—and it will return. If yours is happy (that is, thriving where it is), it should return as well no matter when you cut it. With no detail about your arbor, we offer this: Can you introduce supports to your arbor? Increase its size or strength without cutting the plant? If you cut the plant, perhaps you don't need to cut it to the ground, but can remove only a portion. Be aware that you will get (maybe you already have) new plants sprouting at the base, no matter what you do. We hope this helps!

Wisteria

By Anonymous

I have a wisteria I purchased 4 years ago. It is in a sunny spot, well watered & drained. It now stands about 8 feet tall. I have been trying to train it to climb an arbor. It seems very happy. It blooms profusely every spring and less profusely a few more times during the summer. I recently found out it has crown gall. Is there anything I can do to save my lovely plant? I was told by my local nursery this is a fatal bacterial infection. I have found the crown gall in several locations on the tree and it is at the base of the trunk too.

Crown Gall galling

By Almanac Staff

Tragically, your nurseryman is correct. Crown gall is the result of bacteria in the soil and is fatal; there is no cure. This condition disrupts water and nutrient flow in the plant, weakens it, and stunts its growth. In some cases, the plant can be pruned to eliminate the gall (sterilize your shears after using them on this); it seems, however, that if your plant is affected at the base of the trunk, pruning will have little to no effect. Our sources recommend destroying affected trees. Consult your local nursery or extension service about testing your soil and the possibility of starting another plant elsewhere on your property. We hope this helps...

Out of Control Wisteria

By Anonymous

We bought a house about a year ago. I just figured out that the vine growing like crazy on the back fence is Wisteria. It bloomed last year mostly in the alley and not in the yard where we could enjoy it. No blooms this year,however :(. It is totally out of control from lack of maintenance. I know it needs a good pruning. Some of it looks dead and does not have any leaves on it right now while the rest of it does. How should I go about pruning it.I don't want to prune it back so hard that it won't bloom for years. Help!

Prune the wisteria twice a

By Almanac Staff

Prune the wisteria twice a year. Thin out unwanted mature stems in late winter while the vine is dormant. Next summer right after flowering prune the long shoots of the current year’s growth back to about 6 inches long. Also at this time remove any shoots not needed for the main framework and prune away root suckers.
See more pruning tips above.

Zone 6- Buffalo

Okay so I bought a wisteria stick this spring, put in in a huge pot and this baby is growing like crazy. My question is do I bring it in this winter, or do I put it in the garage with some mulch on it's base and bring it back out in the spring? HELP

Wisteria goes dormant in

By Sarah Perreault

Wisteria goes dormant in winter, so it will be fine if you mulch the base and bring it into the garage until spring. Be sure to give it a good pruning in late winter.
Good luck!

Just curious

By Anonymous

If a Wisteria vine climbs a tree trunk, will it kill the tree? Also, when the Wisteria drops its seed pods, will each grow a new vine? I don't really want to climb 50 feet into a tree to collect the pods before they fall. Thanks.

Although some trees seem to

By Almanac Staff

Although some trees seem to handle it, wisteria can kill a tree that it climbs upon, either by blocking out the light or by girdling the trunk. The pods burst open when ripe, scattering seeds for several feet. Non-native wisteria (Chinese or Japanese wisteria) can be invasive, spreading by stolons/runners, as well as by seed. If you are concerned about the tree that has wisteria climbing on it, it is advisable to cut the wisteria vine off at the base, and keep removing any sprouts that reappear from the roots. The vines can survive for more than 50 years. If you’d like to grow a wisteria, choose a less-aggressive native type (such as Wisteria frutescens) rather than Chinese or Japanese wisteria, and train it on a trellis or arbor, rather than up a tree.

Wisteria stopped growing

By Lenny Brooklyn

I bought a 3 gal., flowering, Blue Moon wisteria, two years ago. Last year it grew seven feet, no flowers. This year it grew one foot, no flowers, and the top lateraled out some. It's on a pergola, four hrs. of sun and the rest bright light. I live in Montana.What happened? Help!

A wisteria needs at least 6

By Almanac Staff

A wisteria needs at least 6 hours direct sun, ideally, for best flowering. Other causes of poor flowering can be too much nitrogen fertilizer, improper pruning, or a severe cold that kills the flower buds. Poor growth might indicate improper soil pH; make sure that the soil is close to neutral, as that allows best uptake of nutrients. Diseases or pests may also cause stunted growth—take a look to make sure the leaves and trunk look healthy and that there are no signs of insects. Avoid soggy soil.
