Why Zucchini Plants Flower But Don't Produce Fruit

Introduction

Zucchini with only male flowers (no swelling at base) may be a barren plant or lack pollination.

Female flowers have a tiny fruit at the base. If present but not setting, pollination is the issue.

Occasionally a plant produces only male flowers. Hand-pollinate if females appear, but yield may be zero.

Check for female flowers. If none, the plant is likely barren. If present, hand-pollinate to ensure set.
