Growing sweet pepper in zone 7b

Start seeds indoors 8 to 10 weeks before the average last frost, which falls between April 10 and April 20 for most of zone 7b. Transplant after soil temperature holds consistently above 65 degrees Fahrenheit, typically late April to early May. First bloom arrives roughly 60 to 75 days after transplanting, placing flowers in late June through mid-July. Harvest for standard sweet pepper varieties runs from mid-July through October. Zone 7b's first fall frost generally arrives between October 20 and November 5, providing a harvest window of 90 to 110 days before cold ends the season. Early-maturing varieties such as Lipstick (65 days) and Carmen (70 days) begin producing well before peak summer heat and continue into fall.

The primary adjustments in zone 7b involve pest timing and disease management. Bacterial Spot of Pepper escalates during warm, wet stretches in July and August; preventive copper applications starting in early summer are more effective than reactive sprays once lesions appear. Japanese beetles peak in June and July and will damage both foliage and developing fruit; handpicking in early morning or targeted neem oil applications at dusk reduce pressure without affecting pollinators. Brown marmorated stink bugs become active from late summer through fall and target maturing fruit; row covers or fine-mesh exclusion netting after fruit set provide the most reliable physical barrier. Verticillium Wilt persists in soil for several years, so rotating peppers and other Solanaceae out of any bed with a history of wilt symptoms is essential. No winter protection is needed; zone 7b growers treat sweet peppers as annuals.
