Reading the season in Columbia
With roughly 245 frost-free days, Columbia 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 16 is late enough that fall planting is a full second season, not an afterthought.
