Peak growing season: August garden jobs in Texas
- Water deeply two or three times a week rather than a little every day - about an inch a week, more in heat. See watering a vegetable garden.
- 13 weeks until the average first frost (November 15). Fall crops start now: brussels sprouts, rutabaga, broccoli, cabbage. See the fall and winter garden guide.
- Check the undersides of leaves twice a week - catching pests early is most of the battle (pest identification guide).
- Harvest often: celery, luffa (loofah gourd), peanut, sweet potato should be coming in. Picking regularly keeps beans, squash and cucumbers producing.
