Reading the season in Twitchell Dam
With roughly 303 frost-free days, Twitchell Dam 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 Dec 4 is late enough that fall planting is a full second season, not an afterthought.
