San Antonio, TXGrowing in San Antonio right now
- San Antonio's clay-heavy soil retains moisture poorly in summer; amend beds with generous compost to improve drainage around deep-rooted okra and squash.
- The city's frequent dust storms can smother foliage; rinse plants early morning or evening to keep leaves clean and photosynthesis active.

San Antonio gardening questions
3Can I start my Tomato plants indoors now for a fall harvest?
No, the last frost date is typically Feb 6, meaning tomatoes should be transplanted directly into the ground starting in April. For this week, focus on sowing heat-loving crops like Bush Beans and Cantaloupe instead.
How often should I water my Watermelon plants during a dust storm?
Water deeply once every two to three days rather than frequently shallowly, as San Antonio's clay soil stays moist longer but dries out rapidly between rains. Mulch heavily around the base of the vine to conserve moisture and keep fruit clean.
My Okra plants are wilting in the midday sun; is this normal?
This is likely heat stress common in Zone 9a summers, especially if the soil lacks organic matter. Provide afternoon shade cloth for a few days while watering deeply at the root zone to encourage recovery.
