Local data

Why this date changes by ZIP

Jacksonville frost history and USDA zone 9a shift the safe planting window. GrowZone uses a local representative station instead of one national rule.

University of Florida IFAS 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.

Pinch the growing tips early for fuller plants. Basil prefers full sun, 10-12 in spacing, and soil near 65 F+.
