Pick fruit regularly to keep plants producing well. Don't wait longer than two or three days between pickings. Cultivate often and shallowly to control weeds. Or, better still, use black plastic mulch in the spring and use leaves in the fall. Few weeds will emerge, and you'll have less work.
Summer squash are kin to cucumbers, watermelons and grounds.
They produce both male and female flowers on the same plant. Honey bees carry pollen from the male flowers to pollinate the female flowers, so don't kill bees. If you use Sevin to control chewing insects, use it late in the afternoon when bees have stopped flying. Sevin kills bees, too. You may want to switch to Thiodan .
