Reading the season in San Marcos
With roughly 274 frost-free days, San Marcos 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 29 is late enough that fall planting is a full second season, not an afterthought.
