Local data

Why this date changes by ZIP

University of Missouri 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.

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.
