Solving Squash Blossom Drop

My squash flowers close and fall off without producing fruit. What causes this and how can I fix it?

Blossom Drop Causes

This condition often stems from fungal or viral issues. Try spraying with Sevin (carbaryl) first. If ineffective, apply a light general-purpose fungicide from your local nursery.

Additional Checks

• Ensure adequate pollination (bees or hand-pollination).
• Check for extreme temperatures or water stress.
• Verify soil fertility—excess nitrogen inhibits fruiting.
