FAQ

When should I plant radishes?

Radishes are a cool crop you direct sow. In zone 7 that's around March 18; the table shows every zone. Cool crops can go before the last frost, warm crops after.

Can I start radishes earlier in a warm zone?

Yes — warmer zones have an earlier last frost, so the dates shift earlier. Compare the zones in the table; a zone 9 garden plants weeks ahead of zone 5.
