Growing Cilantro Outdoors: Timing, Bolting, Succession

title: "Growing Cilantro Outdoors: Timing, Bolting, and Succession"

Coriandrum sativum is a cool-season herb that reliably frustrates gardeners who try to grow it through a hot summer. The plant bolts — sending up a flower stalk and transitioning from leaf to seed production — in response to warm temperatures and long days. No amount of water, shade, or attention reliably prevents bolt once conditions pass the plant's threshold. The practical solution is timing and succession planting, not bolt prevention.

I don't grow cilantro as a consistent staple the way I grow basil and parsley — the narrow bolt window in zone 7a requires more precise scheduling than most of my kitchen herb plantings. The information below is sourced from Extension research.
