Hand Pollinating Squash



Its that time again. The squash plants are blooming! Time to get out the tape and bright ribbon and start pollinating by hand! I love growing squash! I am obsessed with squash like other gardeners are obsessed with tomatoes! Since bees are the only insect that pollinate squash, I started doing the job myself in recent years. It has made a big difference in the number of squash produced. If you usually get a lot of flowers and very few fruits, you may have a pollination problem. Hand pollinating is so easy and its fun! (I think its fun anyway. You may look at it as a lot of work.)

Squash/pumpkin plants, unlike a lot of other vegetables and ornamentals, have both male and female blossoms. The male and female blossoms are very easy to tell apart.


The female blossoms have a receptacle to receive the pollen. This is a female squash/pumpkin blossom:




The male blossom has a small stick covered with pollen. This is a male squash/pumpkin blossom:





The male blossoms grow on a tall stalk, usually towards the center of the plant. These are usually blooming before the female blossoms. The female blossoms don't usually grow until the weather is warm enough. 



As you can probably guess, the object here is to get the pollen from the male blossom into the receptacle of the female blossom. Easy!

At first I used a paintbrush or a finger to capture the pollen and transport it, but shortly discarded that method. Its not necessary. There are usually several male flowers open for every female, so I just pick a male flower, remove the petals and rub the pollen against the female receptacle. You can use one male flower to pollinate 2-3 female flowers, if necessary.

Occasionally there will be a few female flowers open early without any male open to pollinate them. This can be frustrating! That happened to me this year. There were two female ambercup squash flowers open early and no males yet. I pollinated these with male blossoms from a buttercup squash plant nearby. They are both maxima so I know they will cross pollinate. Most of the squash I grow are maxima.

I do want pure seed to save for next year but I knew there would be a lot more squash blossoms coming later. More than enough to ensure pure seed for next year.

It is important, when pollinating for pure seed, to pollinate the blossoms as soon as they open, very early in the morning of their first day before they are likely to be pollinated by a bee. I went out at dawn a few days later, my usual time, and found several female flowers just opening. Perfect!

I pollinated these with pollen from a just opening male flower of the same type and taped the blossom shut with masking tape. You can see the little bulb at the base of the female blossom.



This is a buttercup female blossom just opened this morning, pollinated and taped shut to prevent further contamination from bees with pollen from other maxima squash growing nearby. Cross pollinating squash plants won’t affect this year’s produce at all, but it will mix up what you get from the seeds the following year.






I occasionally go out in the early evening and tape shut any female and male blossoms that I think will open for the first time the following morning. This will prevent any pollination before I get to them.

I marked the hand pollinated ones with a bright pink ribbon so that I will know it is a “seed” squash when it is harvested. Anything that will last through the summer and into the fall and still be recognizable will do. It doesn’t have to be pink! Trail marker ribbon works great! When fall comes I will leave these ones on the vine as long as possible to ensure ripeness. The squash grown for seed will need to be very ripe to get the best developed and driest seed. These will sit in the field in the sun long after the vines have died from frost. Then they will be brought inside and put in the basement to age at least another month before being cut open and used.

This year (2014) I have growing: 12 hills of ambercup and 10 hills of turban buttercup with 3-4 plants per hill of each, 3 pink banana squash plants, 1 spaghetti squash plant, 1 “upper ground sweet potato” squash plant, 2 “sweet mama” squash plants, 3 Hopi black squash plants, approx 4 Hopi gray squash plants and 2 acorn squash plants. Most of the ones I grew this year, except the acorn, are maxima, so cross pollinating would be a problem if done naturally.


I saved a bag full of good dry seed from the giant blue hubbard I grew last year but decided not to grow it again. Its not as sweet as the ambercup, which is delicious, but it is, nevertheless, a tasty dry squash. The hubbards are also more work to process and have to be cut with the axe, or a very sturdy knife and a hammer. I didn’t need another variety this year, so I left it out.

I planted the Hopi squash mainly for seed, although I have read that the gray is one of the best keepers out there. These Hopi squash were the original ones used for the “three sisters” system originating with the Hopi Indians. When I looked into growing them a few years ago the seed was almost impossible to find. I did manage to find one lady who sent me some in a trade and I have kept them until this year. I had my doubts that they would germinate after three years, but they did! They were slow to germinate and I am not sure they will have time to produce mature fruit this year, but I have high hopes! I do so want those seed to preserve and sell next year! We are losing so many good heritage varieties of all our vegetables!

I like to putter in the garden. I often just walk around and look and putter when I am relaxing. This is when I do the pollinating of squash blossoms, tying up and de-suckering the tomatoes, lifting up the stray cucumber vines and so forth – the little things. I keep everything I need in a little basket with a handle and take it out with me on all of my walks. I don’t take the hoe!


Every part of the squash plant can be eaten, including the leaves and tender shoots.

I plan to cut off the side shoots when it gets too late for the plant to grow squash that will ripen in time. These tender shoots are going into soups and stews. I want to try them chopped in omelets this year. The young leaves can be picked now and used as wraps around some meaty concoction, much like a grape leaf can. We have lots of wild grapes too. I think I’ll experiment this summer with leaf wraps!

I have collected a selection of squash recipes that we have found to be delicious and have made many times. Winter squash and sweet pumpkin are interchangeable in any recipe, since they are the same thing. No canned pumpkin will ever taste as good as the home grown vegetable.
