Zucchini

Asked July 7, 2018, 11:18 AM EDT

Why does my zucchini plants set fruit that doesn't mature. They get about two inches long and then either turn hard or shrivel up.

More than likely, your squash is not being pollinated by insects. But you can take over and do it, instead.

Another possible complication is that, during a heat wave such as we've had, is that the temperature is excessive. So, if your hand-pollinating doesn't seem to work, wait until the weather calms down a bit.

To pollinate the squash, use a small artist's brush to transfer pollen from the male (the flower with a long stem) to the center peg of the female (flower with a baby squash already present.)

"Hand Pollination of Squash" is rather lengthy but has all the details, plus images. (http://edis.ifas.ufl.edu/hs398)
