When to Plant in Houston, TX

Houston's subtropical climate means gardening almost year-round is possible — Zone 9a with a last frost around February 15. The Gulf Coast location keeps winters mild, but summer heat and humidity from June through September is intense and challenging.

Houston gardeners follow a three-season approach: a productive winter cool-season garden (November–March), a spring warm-season burst (February–May), and a fall garden (August–October). Summer is largely reserved for heat-tolerant crops.
