Local data

Why this date changes by ZIP

Phoenix frost history and USDA zone 10a shift the safe planting window. GrowZone uses a local representative station instead of one national rule.

University of Arizona 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

Carrots timing notes

Direct sow only; carrots dislike transplanting. Carrots prefers full sun, 2-3 in spacing, and soil near 45 F+.
