Plant Beans (bush) in Zone 8b

Seed-starting, transplant & harvest dates for USDA Zone 8b

Direct sow
Mar 22
Harvest (~55d)
May 16

Zone 8b averages 245 frost-free days, running from a last spring frost around March 15 to a first fall frost around November 15. Beans (bush) needs roughly 55 days from planting out to first harvest, so it uses about 22 percent of that window. Beans (bush) is a tender crop, which is what decides where in the window it belongs.

Beans (bush) resents transplanting and hates cold soil, so direct sow around Mar 22, after the Zone 8b last frost has passed and the soil has warmed. At 55 days to harvest, a 245-day Zone 8b season has room for about 3 sowings, so stagger them rather than planting everything at once.

Planting beans (bush) for a fall harvest in Zone 8b

Yes. Sow beans (bush) by August 24 in Zone 8b. That is 83 days before the average first frost, which covers the 55 days to maturity plus about two weeks for the slower growth that comes with shortening days, plus a two week margin because frost kills beans (bush) outright.

Bush beans mature fast enough for a second sowing almost anywhere with a frost-free window into October.
