Growing Tomato in Baltimore

Baltimore's Zone 7b Mid-Atlantic climate offers around 230 frost-free days — one of the longer seasons in the Northeast. The Chesapeake Bay moderates temperatures, and the city's urban core often runs a week or two warmer than surrounding suburbs. Tomatoes, peppers, and eggplant do especially well here, and the long fall window allows excellent brassica crops.

In Baltimore (last frost around March 28), aim to direct sow or transplant tomato outside around April — approximately 2 weeks after your last expected frost. Starting seeds indoors 6 weeks before the last frost date gives you a significant head start.

Tomato thrives between 60°F and 85°F. It is frost-sensitive, meaning a single freeze at 32°F will damage or kill it — always wait until frost danger has fully passed. Expect 60–85 days from transplant to first harvest. Very frost-sensitive. Needs warm nights.
