Local data

Why this date changes by ZIP

Cleveland frost history and USDA zone 6b shift the safe planting window. GrowZone uses a local representative station instead of one national rule.

Ohio State University 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

Cilantro timing notes

Sow small batches often because cilantro bolts in heat. Cilantro prefers sun to part shade, 4-6 in spacing, and soil near 45 F+.

For fall, count backward from Oct 20. A conservative last sowing target is around Sep 5.
