Reading the season in Harlingen
With roughly 359 frost-free days, Harlingen 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 Jan 3 is late enough that fall planting is a full second season, not an afterthought.
