Plant Peppers in Zone 6b
Seed-starting, transplant & harvest dates for USDA Zone 6b
Zone 6b averages 186 frost-free days, running from a last spring frost around April 15 to a first fall frost around October 18. Peppers needs roughly 80 days from planting out to first harvest, so it uses about 43 percent of that window. Peppers is a tender crop, which is what decides where in the window it belongs.
Because peppers needs a head start, sow seed indoors around Feb 18, about 8 weeks ahead of the Zone 6b last frost. Transplants go out around Apr 29. Starting earlier than that in Zone 6b usually backfires: plants outgrow their cells and stall when they finally hit cold soil.
Planting peppers for a fall harvest in Zone 6b
Yes. Sow peppers by July 2 in Zone 6b. That is 108 days before the average first frost, which covers the 80 days to maturity plus about two weeks for the slower growth that comes with shortening days, plus a two week margin because frost kills peppers outright.
Peppers set fruit poorly above 90 degrees, so a late-summer planting often out-produces the spring one in hot-summer zones.
Fall dates are counted backward from the Zone 6b average first frost, not forward from a sowing date. See the fall planting calendar by zone for the full method.
