- Utilize the unique limestone-derived sandy soils common to the South Texas coast by adding compost to retain moisture against frequent wind drying.
- Take advantage of the mild winter lows (rarely dropping below 30°F) to extend your growing season into November for late harvests like winter squash and borage.
- Monitor irrigation closely during sudden heavy rainfall events typical of this region, as saturated soil can stunt root growth in heat-loving crops like okra and cucumbers.
- Focus on direct sowing this week for cool-weather finishers like daikon radish and lisianthus to avoid transplant shock before the humidity peaks.

- Mulch around newly planted okra and summer savory to retain moisture as temperatures climb.
- Deadhead zinnias and cosmos frequently to encourage continuous blooming through the heat.
Pest & disease watch
- Watch for spider mites exploding in population on zinnias and cosmos due to the combination of high heat and low coastal humidity.
- Inspect okra, bush beans, and cowpeas regularly for pod-borer beetles, which thrive in Corpus Christi's humid summer conditions.
- Check basil, thai basil, and shiso leaves for aphid colonies that often hitchhike on neighboring ornamental vines like morning glory.
Watering this week
Water deeply in the morning to reduce evaporation and keep soil consistently moist but not soggy during this warm season.
Harvest zucchini and yellow summer squash daily when they are young to prevent them from becoming tough and seedy.
Corpus Christi gardening questions
3When should I start harvesting my watermelons and cantaloupes?

How do I protect my summer squash from the intense Corpus Christi sun?
Mulch heavily with straw or pine bark around zucchini and yellow summer squash to keep roots cool during afternoon heat waves.
Is it too late to plant anything new this week for a fall harvest?
