Frost risk in zone 7b
Zones are based on winter cold, not on frost dates, so the last spring frost varies a lot within a zone. Across zone 7b, the typical last frost ranges from about March 30 in the earliest tenth of ZIP codes to April 17 in the latest tenth, and the first fall frost from October 24 to November 18. For a typical place in the zone:
- March 20Risky: a later frost happens in 9 years out of 10
- April 5Typical: frost after this date in half of years
- April 21Safe: a later frost only 1 year in 10
Green Beans are killed by frost, so if you want to be safe, plant out after the safe date rather than the typical one, or be ready to cover plants on a cold night.
