Today’s question comes from Phil in Upper Marlboro, Maryland:
I have squash in the garden that have produced little to no fruit this year. I have 10 plants (one isn’t looking so good) but I’ve only harvested about 15 squash. With the exception of the one plant, the plants look perfectly healthy. Any ideas?
Great question Phil…it’s one that I’ve heard a few times this year. Since your squash seem to be healthy my first thought is that the female blooms aren’t being fertilized. Not fertilized as in N-P-K but not fertilized by the male flowers. Squash are really cool plants that produce two very distinct flowers. When the female flowers, she already has a little baby squash behind the flower. If the flower isn’t pollinated, the little fruit and the flower wither away and die. If she is fortunate enough to receive the pollen from her male counterpart, then the baby squash grows and grows and ends up on your plate. Let’s take a look at the female flower.
See the baby squash? The male flower is similar to the female except that is borne on a little stem. You can think of the stem as the male anatomy if that helps you remember which is which. With the male flower, there isn’t a baby squash behind the flower either. Here is a picture of the male flower.
Do you see the difference? Well, now that we’ve had our squash anatomy class, how can we make your squash plants produce squash? By helping nature along. Take a paint brush or a q-tip and get some of the male pollen and place it in the female flower. You don’t have to put on latex gloves and a white lab coat. Just be sure that the male pollen makes it to the female flowers.
I just realized that I assumed that your squash plants are flowering. If they aren’t flowering, then you have a whole ‘nother issue. If that’s the case, chances are that your nitrogen levels are too high and your plants are focusing on foliage production instead of flowers. If that’s the case, back off of the fertilizer and you should see your plants start to flower. If nature doesn’t take it’s course, then help her along like we talked about above.
I hope that helps you Phil. If any of the other Mid-Atlantic Gardening readers have other suggestions for Phil, leave me a comment below or e-mail me.
