Plant Peppers in Zone 5a
Seed-starting, transplant & harvest dates for USDA Zone 5a
Zone 5a averages 156 frost-free days, running from a last spring frost around April 30 to a first fall frost around October 3. Peppers needs roughly 80 days from planting out to first harvest, so it uses about 51 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 Mar 5, about 8 weeks ahead of the Zone 5a last frost. Transplants go out around May 14. Starting earlier than that in Zone 5a usually backfires: plants outgrow their cells and stall when they finally hit cold soil.
Fall planting: peppers in Zone 5a
Peppers has no useful fall window in Zone 5a. Peppers set fruit poorly above 90 degrees, so a late-summer planting often out-produces the spring one in hot-summer zones.
