Plant Basil in Zone 7a
Seed-starting, transplant & harvest dates for USDA Zone 7a
Zone 7a averages 198 frost-free days, running from a last spring frost around April 10 to a first fall frost around October 25. Basil needs roughly 60 days from planting out to first harvest, so it uses about 30 percent of that window. Basil is a tender crop, which is what decides where in the window it belongs.
Because basil needs a head start, sow seed indoors around Feb 27, about 6 weeks ahead of the Zone 7a last frost. Transplants go out around Apr 24. Starting earlier than that in Zone 7a usually backfires: plants outgrow their cells and stall when they finally hit cold soil. At 60 days to harvest, a 198-day Zone 7a season has room for about 2 sowings, so stagger them rather than planting everything at once.
Fall planting: basil in Zone 7a
Basil has no useful fall window in Zone 7a. Basil blackens at the first light frost, so there is no fall window. Move a plant indoors under a light instead.
