Reading the season in Charleston International Airport
With roughly 265 frost-free days, Charleston International Airport gardens fit long-season crops — melons, winter squash, sweet potatoes — with room left for spring and fall rounds of greens and roots. The first frost around Nov 27 is late enough that fall planting is a full second season, not an afterthought.
