Title: Non-fruiting squash
Answered by: Jimmy Mills

QUESTION:

With all this rain in Dallas why would our Zuchinni and Yellow squash be beautiful and green but not produce any squash?

ANSWER:

The first question Mr. Smarty Plants would ask is are there any flowers? No flowers, no fruit. The flowering process is complex and may be influenced by factors such as temperature and mineral nutrition. With all of the rain this spring, temperatures have been lower than normal over most of the state. This could delay flowering. The ratio of nitrogen to phosphorous in fertilizer that you use may also be a factor. Higher nitrogen tends to stimulate vegatative growth, while higher phosphorous enhances flowering. Since you mention beautiful green plants, you may look into this.

If you have flowers, the problem may be a lack of pollinators. Honey bee populations are declining across the country, and they are sorely missed by farmers and gardeners. Members of the squash family (Cucurbitaceae) are not wind pollinated, and must have a pollinator. The University of California at Davis has a very informative article about this problem, and explains how you can become a pollinator yourself.
