Botanical name: Rheum rhabarbarum

Plant type: Fruit

Sun exposure: Full Sun

Rhubarb is a perennial vegetable, though it is generally used as a fruit in desserts and jams. You only eat the stalks, which have a rich tart flavor. The leaves of this plant are poisonous, so be sure that they are not ingested. Rhubarb is easy to grow, but needs cool weather to thrive.


  • Before planting, eliminate all perennial weeds.
  • Choose a site that is well-drained, fertile, and preferably in full sunlight. It does best where the average temperature falls below 40ºF in the winter and below 75ºF in the summer.
  • Plant rhubarb roots (not seeds) in early spring well before the first light frost so that root development may take place.
  • Dig large bushel basket-size holes. Space rhubarb plants about 4 feet apart and plant the roots 1 to 2 inches below the surface of the soil.
  • Be sure to mix compost, rotted manure, or anything high in organic matter in the soil. Rhubarb plants are heavy feeders and need this organic matter. Don't add a chemical fertilizer when planting rhubarb or during the first year of growth. Direct contact with nitrates can kill your rhubarb plants.


  • Mulch generously with a heavy layer of straw and cow manure to provide nutrients for the plant, retain moisture, and discourage weeds.
  • Water your plant well. It needs sufficient moisture during the summer.
  • Remove seed stalks as soon as they appear.
  • After the first spring, apply a light sprinkling of a high-nitrogen fertilizer (25-3-3 or 10-6-4) when the ground is thawing or has just thawed, so that the fertilizer will go into the ground and not harm the roots.
  • Insects and diseases won't bother rhubarb plants as long as you keep the plants weed-free.
  • Dig and split rhubarb roots every 3 to 4 years. Divide when plants are dormant in early spring (or fall).


  • Crown rot


  • Do not harvest any stalks during the first growing season so that your plants can become established.
  • Harvest the stalks when they are 12 to 18 inches long. Usually after 3 years, the harvest period runs 8 to 10 weeks long. If the stalks become thin, stop harvesting; this means the plant's food reserves are low.
  • Grab the base of the stalk and pull it away from the plant with a gentle twist. If this doesn't work, you can cut the stalk at the base. Be sure the discard of the leaves!
  • Always leave at least 2 stalks per plant to ensure continued production. You may have a bountiful harvest for up to 20 years without having to replace your rhubarb plants.
  • After harvest time, the stems may die back. Just remove all plant debris. Once your ground freezes, it's best to cover rhubarb with 2 to 4 inches of mulch, preferably well-rotted compost; by adding nitrogen to the soil, you're preparing the rhubarb plants for a good spring season.

Recommended Varieties

  • Red rhubarb varieties, which are more tender. Some include 'Valentine', 'Crimson Cherry', and 'Canada Red'.

What do I do with the stalks? (1) Leave them on (1st year growth - I know we don't harvest for eating),(2) cut them off now, (3) cut them off later...
Should I wait do this (cut or leave on) until after I transplant them to their new in-ground home? Thanks!

I've recently planted some rhubarb seeds in my personal green house(it is about 1000 square feet) Unfortunately it is extremely hot in my green house due to the drought so I was wondering if you had any tips on watering patterns, pesticides, miracle grow, etc!

Leave the stalks on the plant. Food from the leaves is needed to nourish the roots for next year's growth. In the fall, after your first frost, remove the stalks and put them in your compost pile.

Hi Penny,

The roots you bought last spring were dormant roots and did well during the year. But you probably will not have great rhubarb this year. Remove the seed stalks now and leave the rhubarb in the pots until you are ready to put the roots in the refrigerator.

Perennial rhubarb is tricky

By Almanac Staff

Perennial rhubarb is tricky to grow in the south. It doesn't like temps. over 90 degrees and it needs a chilling dormant period to recharge. In Texas you can try to grow rhubarb as an annual from seed. Plant the seeds in pots indoors in August and transplant the seedling outdoors when the weather cools in late Sept. early Oct. Let the plants grow during the winter months (they do need protection from frosty nights) and then start harvesting in March until the weather gets too warm.
You can order dormant roots and plant them as soon as possible but it will be hard to keep them going when the weather turns warm. In the fall you need to dig up the roots and put them in your refrigerator for a couple of months before planting them again in late winter.

By Almanac Staff

Most experts advise that you do not harvest rhubarb during the first 2 years after planting. Do not remove more than 2⁄3 of the fully developed stalks from any plant at any one time. Every year after the leaves have died down, spread a thick layer of compost or other well-rotted organic material around the plant, but not touching the plant. In early spring, sprinkle a handful of general fertilizer around each plant.

Can I grow rhubarb in so cal

See answer below on growing

By Almanac Staff

See answer below on growing rhubarb in southern California. The short answer is: you can try growing as an annual but it will not grow as a perennial (coming back year after year). You need to order seeds online. Rhubarb does not grow in sandy soil--quite the opposite. This plant prefers fertile soil high in organic matter with a pH of 6.0 to 7.0. In the fall, cover with thick layers of composted manure.

Rhubarb is a perennial plant

By Almanac Staff

Rhubarb is a perennial plant that usually grows in northern climates because it needs to go dormant at temperatures below 40 degrees F. It usually emerges in spring temperatures that average 75 degrees during the day and 50 to 55 degrees at night. However, folks in more southern climates CAN grow rhubarb as an annual. You need to order seeds online. Here's more about rhubarb production in California: http://anrcatalog.ucdavis.edu/pdf/8020.pdf

Also, what do I do with them during winter (I'm in Washington State). Do I need to cover them or anything?

After dividing, it's best to

By Almanac Staff

After dividing, it's best to wait a season before harvesting. However, if your transplants look healthy and vigorous, you can harvest very lightly the first year, but stop after early July, so that the plant can establish itself.
As to winter care, after a hard frost, you can cover the plant with a thick layer (about 8 to 12 inches) of straw; however, some gardeners prefer not to do this, as it might promote crown rot. In fall, you can also add composted manure in a circle around the roots (but do not add fertilizer the first year after planting).
For best advice for your area, you might contact your county's Cooperative Extension.

Hi Eileen, A common reason

By Almanac Staff

Hi Eileen,
A common reason why rhubarb doesn't grow is because it was planted in the shade and isn't getting enough midday sun.
Also, rhubarb needs cool temperatures to start growing. To even get bud break and growth, temperatures need to be below 40 °F / 5 °C. In summer heat, the plant will grow dormant. As fall approaches and temperatures decline, foliage growth resumes. See what happens in the fall? If nothing happens, you may need to start over in the spring.

By Almanac Staff

Some hybrid seeds are sterile. You don't want to save hybrid seeds as the seed is not true to the parent. Otherwise, you can save seeds from rhubarb though many gardeners find that seeded plants are often of inferior quality. Seeded rhubarb is treated like an annual crop; plants that are allowed to go into their second year tend to bolt to seed stalks quickly. We do not plant seeds; we plant a few roots (or crowns) and treat it as a perennial; every spring, the glorious rhubarb comes back!

Good question. Different varieties vary in color from green to red so color isn't always an indicator. The stalks are most flavorful when fairly young, so harvest them as soon as they have reached their full length and soon after the leaf expands. Depending on the variety, they may be only 12 inches long, or as long as two feet.

rhubarb failed

By Almanac Staff

You know that rhubarb needs a winter chill (below 40°F), right? And a moderate summer (75°F-ish, on average). You do not indicate where you are from.
One of our editors did the same thing and had the same outcome. Twice. (Not very encouraging, huh?) Actually the third time was the charm.
In early spring, she dug a much larger hole (a square yard of space, not merely pot-size, 10 inches down), thus amending the soil (with compost, aged manure, and 5-10-10 fertilizer) in a much larger area. She put the hole in a sunny spot, for full-day exposure. And she made sure that the crowns were near the surface--no more than an inch or so under soil. And she watered to keep it moist, but not soggy.
It seemed to work. The pie was delicious!
We hope this helps— best wishes.

California Girl

By Anonymous

I live inland from Laguna Beach, California. I grew rhubarb very successfully for two years. I had two plants that were in a vegetable garden and planted in the shade of a crepe myrtle tree. Our soil is full of clay. The two plants were Victoria. I did everything wrong. I picked as much as I could the first year and made 4 pies and 4 batches of preserves. I fertilized them with Miracle Grow. The second year I made 7 pies and 4 more batches of preserves. Would have made more but we went out of town in the middle of June for a summer long RV trip. Unfortunately it was SOOO very HOT in Southern California last year that the two plants dried up. They were on a drip watering system but that didn't work when the weather was over 100 for a week at a time. The first of January I tried finding bareroot rhubarb in the nurseries. I found one Canadian Red in a nursery and 2 Victorias at Lowes. Would have loved one more plant but couldn't find one. I am anxious to see what happens this year. Will still pick this year and fertilize because it worked for me.

I live in the mountains above

By Rom

I live in the mountains above Santa Barbara it also gets very hot through the summer. Last year I bought a six pack of rhubarb at Green Thumb nursery in Ventura. I planted them in a raised bed fairly close together.
Five of them grew just like you'd expect, the sixth one just exploded, and we had a hard time keeping up with the amount of rhubarb it produced. Without any exaggeration we got at least ten pies off of the one plant. We never harvested any useable stalks off of the other five, Then, I suppose it was as the weather turned hot all we got were thin stalks and short stalks. The heavy producing one also went to seed. I have just transplanted them and gave them a little more room.
You can find it for sale at Whole Foods in season, and also at some Farmer's Markets.

By MaggieMarie

I am also from Georgia, and while I never grew Rhubarb there, my mother-in-law successfully grew it. You will not have much success if you are South of Atlanta, as it get much too hot and dry during the summer months. She grew hers on the North and East side of the house. It will get plenty of sun, but not the hottest sun from the afternoon. The north side because it will get enough cold in the winter to cause the dormancy. Good Luck.

Rhubarb in Georgia

By Anonymous

Don't buy seeds unless you are planting a HUGE garden. If you just want a few plants then buy bareroots from Burpee if you can't get them in your local nursery. Maybe your local nursery will order them for you and they mights cost less. Good luck. California Girl

The summer heat in the south

By Almanac Staff

The summer heat in the south and lack of cold during winter play a part in rhubarb's scarcity in your area. It can be grown, but you have to prepare. Buy seeds now to start indoors(check www.burpee.com) and plant outside in the spring as soon as soil can be worked. Use lots of compost where you plant your rhubarb. Plant in partial shade, opposed to the usual instructions of planting in full sun. Georgia gardeners also report having more luck with rhubarb when planted on the eastern side of their home or garage.
Good luck!

Rhubarb leaves are toxic so deer and other animals tend to stay away from them, especially given other choices.

Rhubarb isn't well adapted

By Almanac Staff

Rhubarb isn't well adapted for Florida climates though I've heard there is one variety that manages. See this link from your Florida cooperative extension service: http://edis.ifas.ufl.edu/mv124
Perhaps you could go back to your Feed store and ask the variety; then call your cooperative extension to get more local information (and Google the variety!).

If your rhubarb is still

By Almanac Staff

If your rhubarb is still putting out new growth and not dried out, then you can still harvest it! Sometimes cooler nights in late summer can bring on growth. Once it starts to lay down and it doesn't look so great, it's done. Usually it's done in September.

rhubarb with green stalks

By Anonymous

some of my rhubard stalks ar green, but most are red. Are the green any good?

The color of rhubarb stalks

By Almanac Staff

The color of rhubarb stalks can vary, based on the cultivar. For example, Victoria and Linneaus cultivars have green stalks that blush a little red near the base. More recent cultivars, such as Ruby, Valentine and Canada Red, have solid red stalks.

rhubarb leaves

By Farmerboy

I was admiring my garden and noticed that one of my rhubarb leaves was almost completly gone from the inside out. Is this crown rot? And when i harvest my rhubarb will it grow back?


By Almanac Staff

It's hard to say what is plaguing your rhubarb. If it is crown rot, it will be affecting the area where the stems and roots meet, not the leaves.

However, there are particular diseases that affect the leaves on rhubarb . These diseases often create a shot-hole appearance and can be taken care of with good sanitation. Remove all of the flower debris after the first frost. Also, be sure to heavily fertilize at the start of harvest time next year.

harvesting after seeds form

By Anonymous

How long can you harvest the rhubarb, can you harvest and eat after it goes to seed (I did not cut my seed tops off)?


By Almanac Staff

The best time to harvest rhubarb is mid-June. You'll want to cut the tops off after they begin to flower. However, there's no problem if you decide wait longer to harvest them. They are still edible and will not make you sick.

Be aware of freezing temperatures! Temps like this can cause toxins in the leaves to spread to the stalks rendering them as poisonous.

I live in NE TX and have had great luck so far with rhubarb (Victoria variety). Do not harvest first year and keep well watered. Second year harvest only 2 stalks per plant in first two weeks of harvest season (late spring) third year you may harvest up to half of stalks over an eight week period. Bought my roots at Tractor Supply. Good luck!

Where to buy rhubarb plants?

By womenwithwheels

I live in zone 9 - North Texas and I've been told rhubarb doesn't grow here - but I want to give it a try. Our local garden stores don't even stock it. Where can I buy it online?

In northern Texas you should

By Anonymous

In northern Texas you should be in zone 8. I live in zone 8, but in Alabama. I have lived in San Antonio, the climate is about the same. I am growing rhubarb just fine. You do not want to put it in full sun down here. I have read the east side of the house is best. I bought mine at Walmart. You can also buy it at Michigan bulb co. or Burpee.com. Good luck


By dobopatch

I live in zone 10 in Southwest Florida and have planted rhubarb for the first time. What do you think of my chances of survival for my 3 plants. Right now I have 3 leaves on each plant. It gets pretty hot down here in the summer months.

growing rhubarb in hot climates

By Texas.girl

You already bought the plants so all you can do is try, which is what I am doing. I live in zone 8, hot TX. An employee at a hardware store told me it is to hot here to grow rhubarb, but my mom grew it in Sacramento, CA and it reaches 100+ every summer. So I am giving it a try. Hope you succeed, but either way, let others know how the plants do.

The taste!!

By Nona Lopez

Believe it or not, my niece and I would eat this raw right from the garden. Turn your tongue inside out-LOL! We both craved that super sour for some reason.


By Mike Windle

The only fertilizer I ever use is fireplace wood-ash. Early spring as roots poke through earth spread on patch & scratch it in.
Frequent watering is essential.
My patch this year has been the best in years.
