Reading the season in Columbia Lock
With roughly 262 frost-free days, Columbia Lock 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 22 is late enough that fall planting is a full second season, not an afterthought.
