When to Plant in San Antonio, TX
San Antonio's South Texas location gives it one of the longest growing seasons in the state — Zone 8b/9a with a last frost around February 28. The city bridges the gap between North Texas and the subtropical Gulf Coast climate.
The two-season approach works well in San Antonio: a spring garden from February through May and an excellent fall garden from August through November. Summer heat (regularly 100°F+) limits most vegetable production, but the shoulder seasons are outstanding.
