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.

Crop note

Fast crop; harvest promptly before roots get woody. Radishes prefers full sun, 1-2 in spacing, and soil near 40 F+.
