Local data

Why this date changes by ZIP

New York frost history and USDA zone 7b shift the safe planting window. GrowZone uses a local representative station instead of one national rule.

Cornell Cooperative Extension is the kind of local source to verify against when a crop is expensive, weather is unusual, or your yard has a cold pocket.

One or two healthy plants can feed a household. Zucchini prefers full sun, 24-36 in spacing, and soil near 65 F+.
