Why Zucchini Fruit Withers at 2 Inches: Pollination and Watering Issues

Two Main Causes

1. Inconsistent watering – clay soil, too much rain, or overwatering suffocates roots. Provide 1.5 inches water per week; mulch with compost/shredded leaves.
2. Poor pollination – squash sets tiny fruit without pollination, then it shrivels. Hand-pollinate: transfer pollen from male stamen to female flower (identified by swollen base) using a Q-tip or brush.

Soil Improvement

Amend with organic matter (compost, peat, aged manure, shredded leaves) to improve drainage, tilth, and steady nutrition.

Attract Pollinators

Plant bright annuals (marigolds, zinnias) nearby to draw bees. Marigolds also deter rabbits.
