Why these dates work in zone 7a

Zone 7a's last spring frost averages Apr 15 and first fall frost Oct 25 — about 193 frost-free days. Nasturtium is frost-sensitive, so the 1w after frost timing builds in a safety margin against a late cold snap — setting plants out too early risks losing them to frost.

Common questions

How long does nasturtium take to grow in zone 7a?

Nasturtium matures in about 50–70 days from sowing. In zone 7a that means sowing around Apr 22 and first picking around Jun 11.

Will nasturtium survive frost in zone 7a?

No — nasturtium is frost-sensitive. In zone 7a, wait until after the last frost (around Apr 15) to plant, and harvest before the first fall frost (around Oct 25).
