Local data

Why this date changes by ZIP

LSU AgCenter 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

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 Dec 10. A conservative last sowing target is around Oct 26.
