Growing Cantaloupe 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.
