Squash is a seasonal vegetable. It is very susceptible to frost and heat damage, but with proper care it will produce a bumper crop with very few plants.

There are many varieties of summer squash to choose from, including zucchini. The main difference between winter and summer varieties is their harvest time; the longer growing period gives winter squash a tougher, inedible skin. Here are their various botanical names: Cucurbita pepo (Summer squash/Zucchini), C. maxima (True winter), C. pepo (Acorn, delicata, spaghetti) , C. moschata (butternut).


  • If you wish to start seeds indoors due to a short gardening season, sow 2 to 4 weeks before last spring frost in peat pots. However, we recommend direct-seeding for squash because they do not always transplant well. If you do transplant, be very gentle with the roots.
  • If you wish to get an early start, it may be better to warm the soil with black plastic mulch once the soil has been prepared in early spring.
  • The soil needs to be warm (at least 60º at a two-inch depth) so we plant summer squash after our spring crops of peas, lettuce, and spinach—about one week after the last spring frost to midsummer.
  • In fact, waiting to plant a few seeds in midsummer will help avoid problems from vine borers and other pests and diseases common earlier in the season.
  • The outside planting site needs to receive full sun; the soil should be moist and well-drained, but not soggy.
  • Squash plants are heavy feeders. Work compost and plenty of organic matter into the soil before planting for a rich soil base.
  • To germinate outside, use cloche or frame protection in cold climates for the first few weeks. 
  • Plant seeds about one-inch deep and 2 to 3 feet apart in a traditional garden bed.
  • Or, you could also plant as a “hill” of 3 or 4 seeds sown close together on a small mound; this is helpful in northern climates as the soil is warmer off the ground. Allow 5 to 6 feet between hills.

    Most summer squashes now come in bush varieties, which uses less space, but winter squash is a vine plant and needs more space. They will need to be thinned in early stages of development to about 8 to 12 inches apart.


  • Mulch plants to protect shallow roots, discourage weeds, and retain moisture.
  • When the first blooms appear, apply a small amount of fertilizer as a side dress application.
  • For all type of squash, frequent and consistent watering is recommended. Water most diligently when fruits form and throughout their growth period.
  • Water deeply once a week, applying at least one inch of water. Do not water shallowly; the soil needs to be moist 4 inches down.
  • After harvest begins, fertilize occasionally for vigorous growth and lots of fruits.
  • If your fruits are misshapen, they might not have received enough water or fertilization.


  • If your zucchini blooms flowers but never bears actual zucchini, or it bears fruit that stops growing when it's very small, then it's a pollination issue. Most squashes have separate male and female flowers on the same plant. To produce fruit, pollen from male flowers must be physically transferred to the female flowers by bees. If you do not have enough bees, you can manually pollinate with a Q-tip—or, add nearby plants that attract bees!
  • Cucumber Beetle (link to pest page)
  • Squash Bug (link to pest page)
  • Squash Vine Borer (link to pest page)
  • Blossom End Rot: If the blossom ends of your squash turn black and rot, then your squash have blossom-end rot. This condition is caused by uneven soil moisture levels, often wide fluctuations between wet and dry soil. It can also be caused by calcium levels. To correct the problem, water deeply and apply a thick mulch over the soil surface to keep evaporation at a minimum.  Keep the soil evenly moist like a wrung out sponge, not wet and not completely dried out.
  • Stink Bug: If your squash looks distorted with dippled area, the stink bugs overwintered in your yard. You need to spray or dust with approved insecticides and hand pick in the morning. Clean up nearby weeds and garden debris at the end of the season to avoid this problem.
  • Aphids (link to pest page)



  • Harvest summer squash when small and tender for best flavor. Most varieties average 60 days to maturity, and are ready as soon as a week after flowering.
  • Check plants everyday for new produce.
  • Cut the gourds off the vine rather than breaking them off.
  • Fresh summer squash can be stored in the refrigerator for up to ten days.
  • Harvest winter squash when rind is hard and deep in color, usually late September through October.
  • Winter squash can be stored in a cool, dark place until needed. It will last for most of the winter. If you have a cool bedroom, stashing them under the bed works well. They like a temperature of about 50 to 65 degrees F.
  • Freezing Summer squash: Wash it, cut off the ends, and slice or cube the squash. Blanch for three minutes, then immediately immerse in cold water and drain. Pack in freezer containers and freeze.
  • Freezing Winter squash: Cook as you normally would, then mash. Pack in freezer containers.
  • Pull up those vines and compost them after you've picked everything or after a frost has killed them. Then till the soil to stir up the insects a bit.

Recommended Varieties

  • ‘Goldbar’ (yellow summer)
  • ‘Cocozelle’ (zucchini) dark green, slender
  • ‘Butterbush’ (butternut)
  • ‘Cream of the Crop’ (acorn hybrid, prize winning)

Hi I have grown Zucchini from

By kan on March 27


I have grown Zucchini from seeds first time in Delta BC. Plants are really big now Mar27/2015. When I can plant them outside, Please help.

I have my Zucchini plants in

By Shanna T. on March 23

I have my Zucchini plants in pots, and they have done great until now. The top part of the plants are vibrant green like I want, but the bottom leaves appear to be shriveling. The over all plant looks healthy, but those bottom leaves are worrying me a little. Any ideas on what is happening?

Shriveled and/or brown leaf

By Almanac Staff on March 25

Shriveled and/or brown leaf edges can be caused by many things, including a period of cold temperatures (below 50 F) and too much moisture. If there are no signs of spots on the leaves, or wilting, and the plant is doing fine in production, then it's probably not something to worry about. 

Thank you! Should I remove

By Shanna T. on March 30

Thank you! Should I remove the leaves that are shriveling, or leave them on the plant? The rest of the plant looks very healthy, no brown spots or anything like that.

I finally got around to

By Lynnette Meyer on March 21

I finally got around to cooking and eating a spaghetti squash my neighbor gave me last fall - it is now March of the next year. I feel like I have food poisoning. Could it have been too old to eat?

Hi. I started some seeds

By Kristl DeBord on March 8

Hi. I started some seeds indoors in late February. Now, in March, we are getting up to the 50's already. My question is, my zucchini plants are huge already, about 6-8 inches, maybe more. Did I start the seeds too soon? Any advice for handling them until I can transplant outside? Our expected last frost is April 28. We are in central IL. Thanks for any advice!

You can put them into larger

By Almanac Staff on March 9

You can put them into larger pots until it is safe to plant them outside. Good luck!

By jim dehaven

I have 2 crooked neck and 2 zucchini in my green house each plant has at least 7 fruits... and I have no flowers for pollination ,,,,,WASS UP WIT DAT?

The flowers like to open in

By Micah on March 7

The flowers like to open in the morning and may wilt/blend in during the rest of the day. If you attempt manually pollinating, it is best done right at sun up.

Usually, we hear that there

By Almanac Staff

Usually, we hear that there are flowers but the plant is not growing fruit (which would be a pollination issue). If you have the fruit, congrats! You must have had flowers at some point. When the plant stops producing flowers, it will stop producting fruit.

What type of mulch should be

By flsh

What type of mulch should be used around the summer squash plants to avoid getting the squash vine borer?

Research has shown that

By Almanac Staff

Research has shown that mulching with newspaper topped with straw works best. Tightly secured row covers will add extra protection against the adult moth to lay eggs close to the squash plants.

First attempt at butternut

By KimberlyDS

First attempt at butternut squash in Tallahassee, FL (zone 8b); planted seeds in early Sept. I read that b-nut can be planted in the fall here, but now I am worried that we might have an early frost this year, with temps dipping into the 40s already this weekend. There are many 1-2 inch-long squash at this point.

Did I plant too late? Is there any chance my squash will make it to full maturity? How long does it take from the 1-2 inch stage to the full grown stage? And could covering them over night help? Do you have any suggestions?

Covering your plants to

By ken scott on March 21

Covering your plants to protect against frost is a must. Once I even used a candle under a tarp covering my avocados to fend off any frost. and easy fix is to cut the bottoms off of plastic soda bottles and set them into the ground over the plants and then try to cover them with straw or a tarp.

It's recommended to plant

By Almanac Staff

It's recommended to plant winter squash in Aug. if you live in central FL. Sept. planting if you live in southern FL. You may have to cover your plants if you have an early frost. With some luck you may be able to harvest a few butternut squashes before winter.

Hello, i planted squash this

By Marcella Womac

Hello, i planted squash this year in the spring and mid summer, the ones in spring got the squash bore worm and they died and i read that it is best to plant in mid summer so i did but those plants were doing well and then the fruit started getting green worms in them. i don't know what kind they were i did fine a few squash bore worms in the stems but i don't know where the the green worms that bored into the fruit was coming from or how to get rid of them. can you help me so next year i can prepare to combat them.

Especially if you live in the

By Almanac Staff

Especially if you live in the South, the green worms in the fruit might be pickleworms--pale green with brown heads, up to about 3/4" long. They might have reddish-brown spots, depending on the stage of larval development. To help prevent them from boring into the fruit, spread mulch around or keep the fruit off of the ground. They like to feed at ground level. They might also tunnel into flowers, buds, and stems, but prefer the fruit. A larva will eventually spin a thin cocoon, perhaps rolled in a leaf, and pupate. Adult brownish-yellow moths emerge in about 7 to 10 days; they are active at night. Early-maturing varieties are good to combat pickleworm, so that they mature before the peak of the pickleworm population. Also, because the moths are active at night, covering the squash with row cover overnight will help to prevent them from laying eggs on your squash. Remove the cover during the day, to allow pollinators such as bees to visit the flowers. Some varieties of squash are more resistant to pickleworm, such as Butternut 23, Summer Crookneck, Early Prolific Straightneck, and Early Yellow Summer Crookneck.
For more information, see:
If the larvae you see are not pickleworms, perhaps they are melonworms? Green larvae, usually with two white stripes (depending on larval stage). But these usually attack leaves, or sometimes the surface of the fruit. It's less common for them to tunnel into the fruit. See:

thank you for this

By Marcella Womac

thank you for this information you described the worms exactly i will try the mulch next time i plant. fall is here now. looking forward to the color changeing of the trees. thank you again.

i have been growing good

By blue gum

i have been growing good yellow sunburst squash now i am getting a lot of green & green & yellow throw them now why.
i have my squash is next to my zucchini could they cross pollinate

Hi, Blue Gum: Yellow squash

By Almanac Staff

Hi, Blue Gum: Yellow squash and zucchini certainly will cross polinate, but the results are usually not seen until the fruit that grows from cross pollinated seeds in the following year. So this may be something that was in your seeds. It also might be because some sort of stress is changing/expanding the tiny amount of green that is on yellow sunbursts anyway. Sounds like cross pollination at some point, though.

thanks for that

By blue gum

thanks for that

My yellow squash has a huge hook at the neck, the skin is all lumpy and hard as a rock. What's the prognosis?

It sounds like your yellow

By Sandraolt on March 12

It sounds like your yellow squash was a crook neck variety and that they were left to fully develope rather than picked early. If this happens you can cut them up in cubes, add onions and tomatoes and bake at 350 until they are tender. My family likes this dish topped with cheddar.

By Almanac Staff

Hi, Steffi: You're probably OK just leaving it the way it is, but it wouldn't hurt it to prop it up a little so that perhaps the leaves get more light. Don't use soil, though; use something that won't get damp and wet, like wood, stone, or plastic. Thanks for asking!

Thank you very much! I buildt

By Steffi1987

Thank you very much! I buildt a little trellis with wire for now. Another question , when should i start guiding the leaves thru a "real" trellis ? Wont it hurt the plant when it stucks in the wire and grows taller ?

Butternut squash might be too

By Almanac Staff

Butternut squash might be too heavy for a light trellis; make sure that you install a sturdy one if you will be vertical gardening. As for the stems growing through the openings in the wire mesh, they should be fine as long as the trellis will not wobble, the mesh is fairly wide (at least a few inches wider than the width of the mature stem), and the stems are supported. Some gardeners weave the young stems through the wide mesh to help with support. Others secure and guide the vines by tying them at intervals to the wire. If you want, you can even redirect the vines to remain on one side of the mesh, rather than growing through it. With such heavy fruit, it's best to provide support for the developing squashes by making a sling with pantyhose and tying the sling to the wire.

Spaghetti squash growing

By John wish

Spaghetti squash growing great came down with white spots looks powdery mildew it still has time to grow is the fruit still edible to eat Thanks John

Powdery mildew most often

By Almanac Staff

Powdery mildew most often attacks the leaves, but in severe cases, can also attack the fruit. Do you notice any white spots on the leaves? If it is powdery mildew, it's best to remove infected leaves and fruit, especially if there are other leaves and fruit that are showing no signs yet. Improving air circulation helps combat the disease. Fruit with powdery mildew might still be edible, but most likely the flavor and quality would be off. For more information, see:
White growth on fruit might also be Pythium, or fruit rot. The fruit is infected when it rests on wet soil, and may form cottony white growth, especially in humid weather. In severe cases, it is not edible due to poor quality. For more information see:

I have huge Zucchini and

By mark menser

I have huge Zucchini and yellow squash plants but no squash. I understand that this may be a pollination problem but there are no flowers either. It is now early august. Should I just pull up the non-producing plants and replant seeds?
I read that another source of my problem may be too much nitrogen in the soil. My yard has hard clay soil, (very hard!) So I built an above ground garden and filled it with commercial potting soil. Was this wrong? How can I correct the nitrogen balance now?

Yes, lack of blooms is

By Almanac Staff

Yes, lack of blooms is generally due to excess nitrogen. You could sprinkle some superphoshate around the plants. It may not work this year, but you can try it. What will be important is that you get a soil test before you plant next year. There are home gardening soil tests you can get from your local cooperative extension or from local places for a small fee.  Then adjut the soil as needed.

One of my zucchini plants has

By Graceyreeves

One of my zucchini plants has been producing zucchini with divots (like pock marks), so they look like concave bumps. What causes this? Are they still okay to eat? Thanks.

Hi, Gracey: The puzzle here

By Almanac Staff

Hi, Gracey: The puzzle here is that it is only one of your plants. It's possible that there is some sort of pest involved (see Pests above), so do some exploring of the dimples. Sometimes these can be the result of damage when the zukes are young, but this would not seem to apply. Another thing that can cause this is a quick temperature change that causes the moisture content near the skin to vary. But all the fruit on only one plant? Readers?

After a squash plant is

By Simplyeric

After a squash plant is reaching a good size, can you mound additional soil/mulch at it's base (the way you can with tomatoes, for example)? We got some squirrel damage, and it's healing but somehow I thought a little additional soil might help.

We plant our squash seeds in

By Almanac Staff

We plant our squash seeds in mounds from the start.  Once the seedlings are 2 inches tall, you can add mulch. And feel free to add more mulch as they grow.
This "may" help with the squirrels.  The only real defense for small critters is a fence. Also, you can use safe repellents when the seeds are young and vulnerable. Ingredients in repellents may include animal predator urine, blood meal, garlic, sulfur or hot pepper, among others. Spray around your vegetables, not on them. Once the plants are past the tender seedling stage, they tend to fare better.

How many winter squash can a

By Van K.

How many winter squash can a healthy plant produce to maturity? Is there a recommended # of winter squash per plant?Then should all subsequent tip growth be curtailed?

The number of winter squash

By Almanac Staff

The number of winter squash per plant will depend on the kind and the variety, as well as the health of the plant, the soil, the weather, vine length, pollination, spacing, any techniques that you might be able to do to increase yield, etc. On average, an acorn squash might produce up to 5 per plant; butternut, 4-5; pumpkin, 1 to 3; others, up to 7 or more. In general, the larger the squash, the less fruit will form per vine (although there are exceptions). Check the seed packet to see if it mentions the average yield for that variety.
Some people do remove new flowers, or prune the growing tip of the vine, once there are about 3 to 5 good-sized fruit growing, to encourage the plant to focus its energy on growing fewer but larger fruit (such as pumpkins). Some don't do anything, and let the plant grow as it will. Your strategy will depend on whether you'd like lots of smaller fruit, or fewer but larger fruit (such as for exhibition).

I have a green house first

By new green house grower

I have a green house first time this year. In our excitement for the garden we have over crowded the zuchinni and yellow squash I'm pretty sure. the raised beds in the green house are well stocked with organic soil, well watered, plenty of light, and I fertilize about once a month. The plants have overgrown greenery, and I did prune them once. They continue to produce big leaves, but the produce I'm getting is very limited, despite my hand pollination every morning. The squash have quit producing any female flowers, and the zuchinni is very limited also. The are so crowded that you can't help but step on some of the leaves and the roots(deep purple) have gone to the far edges of the beds on each side. I'm assuming this is due to crowding. Is it too late, middle of July in Albq NM, to pull them and start over?

The heavy leaf growth may be

By Almanac Staff

The heavy leaf growth may be the result of too much nitrogen in the soil. The N-P-K of fertilizer means
• Nitrogen, for leaf growth
• Phosphorus for root growth and fruit production
• K = potassium, which helps a plant to fight off disease.
To see if you have a second-season opportunity, key your zip code into this page and check the planting table ("Candia, NH" wil be replaced with your location):

This is my first time growing

By Shianne

This is my first time growing zucchini and I was just wondering if I have to dig them up when the first frost hits? Or should I leave them in the ground? If I leave them in the ground will they come back in the spring?

Zucchini is an annual; it

By Almanac Staff

Zucchini is an annual; it grows for one season. Pick any zucchs before the first freeze—even a near freeze, if they are mature. If the freeze, or deep chill, is expected to be brief and warm temperatures are expected to return, you could cover the plant to protect it from the cold. Depending on the forecast (how cold for how long), a row cover, bedsheet or the like would do. You don't want to the leaves or zucchs to be touched by the frost. Remove the cover when temps rise.
Remove the zucc plant when it has finished producing or if it is killed by a frost. Make its removal part of your end-of-season garden clean up.

My plants are producing males

By Susancologardener

My plants are producing males and females but the females are not growing further even though I've been pollinating them by hand to make sure they have been pollinated. I live in Colorado and it's been consistently in the 90's. I water everyday and dug compost into the soil as well. Last year I had a very abundant crop but this year the females are just not producing. What could be the reason why?

It sounds like you're doing

By Almanac Staff

It sounds like you're doing all the right things, Susan. 
One suggestion is to maybe let nature take its course. The plants produce both male and female flowers, usually enough for pollination.
One question: are you pollinating in the morning? At that time, high humidity helps to activate the pollen.
Then again, sometimes plants produce all male or all female flowers. The sex can be influenced by temperature, day length, maturity and hormones.
One other thought: back off the watering for a bit. While zucchs like moisture, they also appreciate a brief dry period between soaks.
Hope something happens soon...

I have a question. I cant

By nicole marden

I have a question. I cant find this one anywhere either. I accidentally snapped the stems clear off on two of my plants. Theyre still babys, only just got their second leaves. I stuffed them as far into the dirt and watered as soon as it happened. Do you think (or know if) theyll grow new roots and be fine? They dont seem listless and its been over 24 hours since it happened. Thanks so much

I also accidentally broke one

By MRamos

I also accidentally broke one of my plants at the base, just above soil level. I taped it with cheap scotch tape, immediately. That was nearly a month ago. Now the plant is smaller than the others, but is producing flowers before the other plants and much more of them.

I planted 38 yellow squash

By Ida Graham

I planted 38 yellow squash plants. Each plant is full of blooms, but the blooms are dying. There are no squash growing on the vines. What is wrong?

Are you losing male or female

By Jess78

Are you losing male or female flowers? Usually the first flowers you see are males, they come out first so they are ready for the females. The makes will drop off when they need to. Female flowers falling off usually means they were not pollinated.

I started my very first garden this year. Unfortunately we have to move :( I want to take my plants with me but I dont know what the best way to do that would be... HELP PLEASE! I have squash, zucchini, cucumber, watermelon, cantaloupe, tomatoes, jalapenos, and strawberries. Please help me keep my garden!

It is possible to move a

By Almanac Staff

It is possible to move a vegetable garden, but it is a huge undertaking (especially for larger gardens), and some plants may not survive. Success will depend in part on how large your plants are now, how long they will be in transit, and what the conditions are in their new space. If these plants are young, less than a foot tall, then it will be easier to pot them up. Keep in mind that some plants do not like to be transplanted, or are at a stage of development when it is hard for them to adjust, and may not fruit.
In the evening before you move (when it's cooler), water the area around the plant thoroughly, dig up the plant carefully, disturbing the roots as little as possible, and transplant it to a deep pot. Include as much of the root ball and soil as you can--the rootball width should at least be a few inches wider than the width of the plant; the wider, the better. And the deeper, the better.
Protect the plant from wind/sun/heat during transit. Plant it in the new location as soon as possible--next day is best (otherwise, keep it watered and shaded. Do not store in a moving van over days, as it can get very hot there).
Pick a protected new site in full sun. Be sure that the new soil has been prepared to receive the plants (loosened, weeded, rocks removed), and has good soil (well-aged compost worked in; do not add fertilizer or manure at this point, or it may burn the plant). If you are moving only a short distance away, it would be good to prepare the soil before moving day.
Plant in the evening, so that sun doesn't stress the plant for a while. Water the soil before planting and after. Provide temporary partial shade. After the plants recover from shock and establish, you can remove the device creating partial shade so that the plants can enjoy the full sun. Keep up with the special watering for about a week or so (but don't let the soil get soggy), then taper off to normal watering levels. 
Good luck!

Why do squash plants fall

By Barbara-Lynn

Why do squash plants fall over? Should I prop them up with something or leave them the way they are? They are healthy and vibrant and just starting to produce fruit. It just rained a lot recently.

For hand pollination...I've been doing it with my finger and seems to be working well. Are there drawbacks to doing it this way?

I place tomato cages over my

By Jess78

I place tomato cages over my squash plants when they are very small. This supports them but also allows me to pick the fruit easier. At this point you should get stakes the same height as the plant, put it in the soil next to the plant (carefully), make sure you are not on the root side, then use old t-shirt strips to tie the stalk to the stake.

Hand pollinating is ok but you could transfer bacteria to the plant, I use brand new q-tips to pollinate if I don't see the bees doing it. If you see a lot of bees around the blooms early in the morning you should not need to pollinate by hand.

I have a weird situation this

By Heather F

I have a weird situation this yellow crookneck squash have a ton of immature fruit on them, but they only mature into tiny 3" fruit. They are bumpy, deep yellow, and tasty - definately not unpollinated - but tiny! It's a new garden plot and it has a cover crop of clover. Is my soil deficient? Is the clover robbing the plants of something they need? The plants are really healthy looking so i don't think i'm overwatering. The soil we got for it was a really gorgeous decomosed granite that we harvested out of a mesquite stand and we've been amending it as we go, but it's the first season with this soil so there hasn't been a heck of a lot of organic matter in it yet. Everything else we've planted in this soil is doing great.

If a flower is not pollinated

By Almanac Staff

If a flower is not pollinated enough (it requires several visits), it can result in small or deformed squashes (such as small squashes with tapered ends, and only a few of the seeds inside maturing); hand pollination will help new flowers along (squash has male and female flowers). Sometimes cool weather will slow pollinators, causing inadequate pollination at the time of flower formation.
Since the fruit seem to be tasty and not misshapen, and if the plants seem healthy, it probably is not a virus, which can deform fruit as well.
Check the end of the fruit--if it is brown, it might be blossom-end rot, which is caused by not enough calcium intake. In this disorder, fruit develop up to a point, then brown at one end and rot. Even if soil has calcium, the plant needs enough water to draw it in--if you think this may be the cause, make sure the plants are consistently watered (but not waterlogged); check the soil pH to make sure it is not too acidic (below 5.5; optimum for growing, 6.0 to 6.5). Avoid too much nitrogen.

After a squash is growing,

By Judy Efifd

After a squash is growing, can you take flowers off? Or will that stop the growing process? Thanks.

Once you have a squash

By DW-83

Once you have a squash growing and the flower has wilted, the flower no longer serves a function. That being said, there is no need to remove the flower. It will dry up and fall off in its own good time. I would leave the plant as it is and let the flower fall off naturally.

My squash plants aren't

By Greenhorn

My squash plants aren't leafing out, they are just little sprouts still. But they are blooming already. Is this normal? If not what should I do?

I planted Spaghetti Squash in

By Lorelei R

I planted Spaghetti Squash in Mid March. Weather was warm in So Cal. The plant looks healthy and green with many male flowers. I have seen only 2 female squash which have been pollinated. My problem is I don't find any more female stems, only male. Is there anything I can do to promote more female to start?

By Almanac Staff

The weather can slow things down but have patience; the female flowers will follow the males eventually!

My squash vines are huge and

By betcb

My squash vines are huge and are blooming now. We have them in a raised bed with tomato cages upside down. They are already getting towards the top. Does it matter if the vines are large or should we take off some leaves for the sun to get to the blooms?

We have beautiful healthy

By Tambra

We have beautiful healthy yellow squash plants. We still do not have any flowers on them at all. We have had unusually cool temps for May and lots of wet weather . Should we be concerned that we have no flowers yet? Why don't we ? What can we do ? Thanks

You are correct in saying

By Almanac Staff

You are correct in saying weather may play a role. It has been a cool, wet spring in many parts of the country. Cool weather with temperatures below 75 degrees Fahrenheit can delay flowering. Another reasons could include dry soil or overcrowding. 
Sometimes a plant won't produce flowers if it receives too much nitrogen. Squash likes low nitrogen and higher phosphorus and potassium. If you think it might be too much nitrogen, you might apply some amendments that contain phosphorus and potassium to balance the nutrients. Ask a local garden nursery for options and timing.
Once it's warm enough, expect most summer squash to flower 35 to 45 days from germination.

My neighbor has a problem

By Janet Stinson

My neighbor has a problem with his squash plants. Oddly, the plant leaves start turning brown around the edges and eventually die, but the squash keep producing nicely. Local agents mention "blight", but otherwise confess that they do not know the reason. Is it simply some sort of stress on the plants due to improper watering practices, or maybe soil problems, since it has been happening for the last two seasons? Should he even worry about it?

Brown leaf edges can be

By Almanac Staff

Brown leaf edges can be caused by many things, including a period of cold temperatures (below 50 F) and wet weather. If there are no signs of spots on the leaves, or wilting, and the plant is doing fine in production, then it's probably not something to worry about. If your friend is curious, though, he might talk to his county's Cooperative Extension. Sometimes they will do tests to check for plant diseases, for a fee. For a list of agencies, see:

I started yellow squash and

By Kgardener

I started yellow squash and zucchini seeds and the yellow squash plants 6 weeks out are enormous and healthy with several green 4 inch leaves. The zucchini on the other hand is short with only 2 marginally healthy looking leaves, the others fell off or I plucked off perhaps wrongly because they were yellow or dry and brown inorder to save the plants energy to produce healthy leaves. But now it's starting to flower which seems way too early. Do I pluck the flowers? I've already plucked a few I feel like there's nothing left to this poor plant. Will the plant recover or should I start over?

Even if conditions were

By Almanac Staff

Even if conditions were exactly the same for both squashes, the results may not be the same.
Zucchini seed germination requires a minimum soil temperature of 60°F, according to several sources, with a pH of 6.0 to 7.5. BTW, one even advices starting both squashes in the ground, to avoid transplanting failure.
It's difficult to know eactly what went wrong. See what happens with the existing seedlings, and try again and, if you do, save a couple of seeds to set directly into warm soil in the garden.

By Almanac Staff

This squash problem is probably blossom end rot. It won't spread but indicates a lack of calcium in the developing fruit.
You may have soil that is too acidic. The pH of acidic soils can be raised by adding lime, but this should only be done if soil test results indicate it is needed. To change pH, lime should be tilled into the soil 6” to 8” deep 2 to 3 months before planting (or as much lead time as possible) to change the nature of your soil. A little sprinkling of lime won't do much once they have the rot.

Based purely on your description, this does not sound like blossom end rot—which affects the lower ends of the squash (on the blossom end side) not the flower itself. It is possible that you have pollination issues? You can always self-pollinate between the male and female flowers to ensure pollination happens. See this page for more detail.

My zucchini and yellow squash

By Wayne Ames

My zucchini and yellow squash were producing like crazy and now seem to have stopped completely. Are they all done for the year? I am in South East AZ and we have been getting a lot of rain lately due to monsoon season. We are in the mid 80's to low 100 degrees daily. We typically don't get freezing until the end of August. Should I remove the dormant plants and plant a new crop? Will I have enough time for them to produce? This is my first year gardening so I am learning as I go.

I have different varieties of squash growing. I kept my summer separated from my winter. I check them daily ad they are growing some vey nice produce. We've been eating squash a lot lately.
I too once noticed the powdery mildew growing on my zucchini. I try not to use any herbicides or chemicals because we have free range poultry on the farm. One tip that I read about and used is to use milk. Get a spray bottle and mix milk with water in the ratio of 1 part milk to nine parts water. Spray the leaves of your plants until the liquid begins to drip once or twice from the leaves. I don't have a particular time to say to do this but I do it in early morning once a week and it seems to have saved my squash from an inevitable fate. It worked. The source also said to use on cucumbers and tomatoes or anything else that may be susceptible to powdery mildew. Hope you have the same success as I did.

By Alaina

I planted a ton of yellow & green squash out back this year, my first year ever growing. I have harvested about 8 yellow squash so far- but NO Zucchini. Not one. It seems an irritating group of rodents (they've eaten too much to be only one) have moved in on my zucc's and eat all my femal blossoms long before they can bloom. VERY Depressing. However, my question is; if a female flower blossom is pollinated, then eaten off the tiny yellow (or green) squash, will the fruit still grow to maturity? Or does the flower need to stay put for awhile until the squash is well on its way? :( The Voles are starting to eat my baby yellows now as they have completely consumed my zuccs!)
Is there ANY thing I can spray (organically) around my zucc's to save at least ONE zucc from any of my 30 zucc plants!? Thank you.

The tiny fruit at the base of

By Almanac Staff

The tiny fruit at the base of the female blossom is what grows into the big fruit. If it's eaten after polliination, then the fruit will not mature. In terms of zucchini protection, it really depends on the pest. We doubt the issue is voles as they are usually springtime pests. If you are sure you have a rodent issue (versus beetles or slugs or other pest), it could be rabbits. See ways to deter rabbits here:

Your diagnosis seems correct.

By Almanac Staff

Your diagnosis seems correct. The flowers were not fertilized because of the lack of bee activity. This can be influenced by rain and weather conditions. To aide pollination. With a Q-tip, take off the pollen from the stamen of the male flower and brush it onto the female flower's stigma in the center. You could also pluck a male flower (the one without the bulb or ovary at its base), strip off the petals, and use its pollen-covered stamen as a brush. Do this all in the morning when both male and female flowers are open. Next year, get some bee-loving flowers for natural pollination!

By Almanac Staff

Hi, Nikki, You'll need bees to pollinate. Ants don't pollinate, though they may end up dragging some pollen around while they are there.

So make sure you check under the leaves for aphids--and blast the aphids with a diluted soap spray early in the morning.

By Almanac Staff

Yes, squash can "sweat"--as can other vegetables! It's nothing to be worried about. This usually happens when it's exposed to alternating cold and warm temperatures which simply causes moisture to accumulate no the surface. If you salt your squash, you'll also see it "sweat" as the salt draws moisture from the inside.
If you are eating your squash soon, don't sweat it. If you want to store it to keep longer, however, make sure your storage area is cool and prevents temperature variation to avoid decay; stored veggies also need good air circulation/ventilation.

By LaurenRitz

I assume you mean the difference between male and female blossoms. Basic and most visible difference: The male blossom has a long, leggy stem. The female blossom has a bulb at the base. This bulb can be small or large, and of varying shapes depending on the type of melon or squash. The bulb is the nascent fruit. All zucchini come from female blossoms.

If you look inside the blossom, the male has pollen covered upright stalks at the center. Inside the female blossom you'll see a small split bulb with a hole in the center, but no pollen.

Jean, this question is asked

By Almanac Staff

Jean, this question is asked (and answered on this page). In general, all of the early flowers are males. Female flowers often develop many days later once the climate is ready for them. The females can be identified by the miniature fruit at the flower base.

It's normal for male blossoms

By Almanac Staff

It's normal for male blossoms to drop, especially early in the season. If you see female blossoms dropping, it's because they're not being pollinated; this due to weather extremes or lack of bee population. If it's temperatures, fruits will appear when temperatures moderate. If it's a pollinator issues, make sure you're not using toxic chemicals to spray your plants as they kill the bees; you can try to pollinate the plants yourself with a Q-tip.

By Almanac Staff

Not being able to see the fruit, we can not identify it, and therefore would advise not eating it. We haven't heard of yellow squash turning purple later in the season (although we suppose it is possible if it had a cultural or pest/disease problem). It might be that you have an heirloom type that exhibits this trait, although a particular cultivar doesn't come to mind at the moment. Could it be possible that the original plant has died back and a volunteer is now growing in its place? It could be an edible vegetable, such as eggplant, but it may also be an inedible weed. To be safe--don't eat it! You might want to bring a sample to your local Cooperative Extension (if in the USA) for identification. To find your Extension, go to:

The most common reason for this problem is lack of pollination. There are female and male flowers. Sometimes the females bloom before any male flowers have bloomed and so the female flowers do not get pollinated. Usually, if you wait, you'll find that the males start blooming and you're getting TONS of squash! If not, there's a lack of pollinators in your garden and you can do it yourself with a Q-tip.

I am having a similar issue with lack of pollinators. You mention that if there is a lack of pollinators, to hand pollinate. However, that assumes there are male flowers, and I do not have any on my crooked yellow squash (only females). I had one on my zuchinni, and used that to hand pollinate my crooked yellow squash (I used my finger). I have several questions- is variety cross pollination effective, and what do I do if I don't get anymore males? Should I cut off the females so they aren't taking resources from the plant? Is using my finger effective- or should I not consider them pollinated? Guess I will have to wait and see. The one male flower from zuchinni plant fell off last night in a storm, I think I will try and reuse pollen from inside to continue in variety cross pollination.

Good sleuthing. Yes, small,

By Almanac Staff

Good sleuthing. Yes, small, reddish-brownish eggs on the underside of leaves in evenly spaced groups indicate squash bugs. Frankly, this is the most loathsome of pests and there is not a lot you can do once your plants are attacked. Control in organic gardening is done before seeds are even planted by removing overwintering sites with post-harvest tillage, removing and even burning all vines and debris, cover cropping, rotating crops, using tightly secured row covers until flowering starts, planting resistant types (e.g, 'Butternut'), interplanting buckwheat to attract a predator fly, companion planting with bug-repellant flowers (e.g., marigolds, nasturiums), and planting nearby "trap" crops of plants that squash bugs prefer (e.g., Hubbard). If you catch the pest early --on just a few vines--hand pick the pests and crush the eggs daily. Some organic gardeners say using diatomaceous earth (DE) slows them down. Others say to spray with Neem oil, a natural pesticide; spray on all leaf and stem surfaces. One expert gardener recommends Bayer Advanced Fruit & Vegetable Insect Control. Ask your local garden center about these products and follow directions very carefully. One of our readers says to put the squash bugs in a blender, add some water, wait a day, and spray THAT on the pests and it works. Warning: they are very smelly!
Now, Sevin is a chemical. I believe it's for the base of the plant, below the flowers, but follow the directions very carefully. Note that Sevin is extremely toxic to honeybees (our dear pollinators). Many farmers use pesticides and will tell you timing is critical. Application must happen early during maximum egg hatch. Otherwise, it may be back to those preventative controls.

Great question. Once you know, it's easy to tell the difference. Female flowers look as if they have a miniature fruit right under the petals. Male flowers have a slender stalk below the petals and that's it. It's normal for the male flowers to fall off, especially at the beginning when there may not be females yet. If the females start to fall off, then there may be a pollination issue.

squash problems

By Almanac Staff

If the squash fruit gets an inch or two long and then dies, it is probably related to pollination. Female and male flowers need to blossom at the same time. So, it may just be a question of waiting until both are blossoming. Tips: To attract bees, avoid spraying pesticides as well as covering the squash during morning pollination. Avoid overhead sprinklers. If the weather's been too rainy or overly hot, you may also need to wait for conditions improve. Finally, you can always attract more bees with nearby plants (example: plant bee balm).

Additional pests, pollinating, flowers, etc.

PESTS - In the south (Texas), I've run into problems with cabbage loopers and melonworms. I had to spray Bt (an approved organic solution) to get them to go away.

POLLINATION - It's possible to pollinate the flowers without bees. Basically, you carefully open the flowers (if they haven't already), remove the "dusty" component (male?), and rub it against the other one.

FLOWERS - The flowers are great to eat straight from the plant. The fruits (veggies) also! In fact, I've had to do that to keep them from the squirrels, who have done damage to the nearby stems, being clumsy in their gnawing.

By Teddy

Not only do cantaloupe need a pollinator but several other things can prevent the flowers from forming fruit: temperature and watering methods being at the top of the list. Cantaloupes prefer being watered at ground level and the temps near to be at a steady 85-95 every day for a couple weeks will signal the plant to produce a viable blossum. Since most of you are writing your questions at the beinning of July, depending on where y'all live, the temperatures might not have reached the prime target for viable blossum development. The pollinators can tell by the aroma of the blossoms if the blossums are viable or "ready." Pollinators tend to have a keen sense of weather prediction and "knowing" when to pollinate certain plants. Bees especially will not waste their time with nectar that is not ready. ;)

I bet y'all have fruit by now. Blessings!!!!

I had no luck with my squash, it keeps blooming but no fruit. Why is that pls help.

Hi Cowell, Have you seen any

By Almanac Staff

Hi Cowell, Have you seen any bees buzzing around the garden? Bees are necessary because squash plants need to be pollinated in order to produce fruits. If there are no bees, you can manually pollinate the plants. Try putting the pollen on a q-tip and transferring it from male to female flowers. That should do the trick. Good luck!
