From Plot to Plate-Squash Sex in the Garden

My last post on Squash Birth Control showed you how to decrease your squash harvest. But how about if you want to increase your harvest? Maybe you only have one plant to work with and you want to eat squash every night? It is easy to increase your odds of growing fruit as each squash plant bears male and female flowers and you can use this to your advantage without the help of pollinators. You become the pollinator!

An early morning harvest of squash blossoms, mostly male, but a few female ones

Most gardeners look at their squash plant blooming and see tons of flowers and start making plans for all that squash, pulling out recipes for squash bread and zucchini cake. Over the next week, you see with chagrin the blossoms fall off, some with small squash attached and wonder why? In reality, most of the flowers are male flowers and produce no fruit and pollinate the much fewer female flowers.

Learning to distinguish between male and female flowers on the vine will help you figure out what your true harvest will be. Both male and female flowers occur on each plant and pollen from the male flowers has to make it to the female by way of insects or hand pollination. This is where the gardener can lend a helping hand.

The video below shows a snapshot of morning activity of flying insects in my squash blossoms. I have three hives so there is always lots of visiting bees to my flowers. But everyone doesn’t maintain bee hives and you can increase your odds of your squash flowers getting pollinated even in an urban situation by simply hand pollinating.

Here you can see the difference: The female flower on the left with the enlarged center, the pistil, and the male flower on the right which carries all the pollen grains

The first week or two it is normal for the blossoms to fall off as only male flowers are produced and then the female flowers start opening. For pollination to occur you need bees- native, bumble, or honey bees and other insects, or a handy Q-tip!  If there is a dearth of bees, pollination is a lot less likely to occur, but not to worry- this is very easy to do yourself.

Removing all the flower petals from the male flower, touch the pollen bearing anther to the stigma of the female flower

Simply take the petals off of a male flower and use the ‘brush’  or exposed anther and brush it against the stigma of the female flower thus transferring the pollen manually and ensuring that the female flower grows a fruit. You can also perform this with a Q-Tip very easily in the vegetable plot. I prefer to fertilize directly with the male flower and go to each female flower that I see, brushing the anther against the stigma of the female flower. Fertilization is necessary for fruit formation. If fertilization does not occur, the ovary  or little squash will wither away. The squash flower below on the right has successfully been fertilized and is starting to grow.

On the bottom left is the male flower; top middle is a female flower; bottom right is a female flower that has closed up, pollination has occurred and the squash fruit is starting to grow

Male flowers greatly out number female ones and I take advantage of this and pick baskets of male flowers for recipes. Of course to cut your harvest, simply remove the fewer female flowers which can also be used in recipes. Just remember to cut off the center part, the stigma bearing part, as this can be tough.

Here is one of my favorite recipes-Oven Fried Stuffed Squash Blossoms. Instead of messy deep-frying, I like to cook them at a high temperature in the oven. Serve with a dipping sauce, like a blue cheese mix.
