What to Do in Your Central Texas Garden (July 15–31): Prune Now & Plan for Fall
Late July is one of the hottest times of the year in Central Texas, but there’s still plenty to do in the garden. In this episode, Colleen shares practical tips for dealing with chiggers, why she recommends avoiding French drains, how to prune trees, shrubs, fruit trees, and perennials during summer dormancy, and what vegetables you can still plant before fall arrives. She also explains how to calculate planting dates based on your area's average first freeze and encourages gardeners to save and share seeds with their local community.
🦟 Chigger Prevention & Relief
Chiggers seem to be especially active this year, and Colleen shares her favorite ways to prevent bites and relieve itching.
Prevent Chigger Bites
Apply a DEET-based insect repellent to shoes, socks, and pant legs.
Dust clothing or landscapes with sulfur powder (keeping pets away until it's watered in).
Avoid direct contact with areas known to have chiggers.
If You Get Chigger Bites
Take Benadryl at night to help reduce itching.
Apply witch hazel with a drop or two of peppermint essential oil.
Use peppermint soap to soothe irritated skin.
💧 Why Colleen Doesn't Recommend French Drains
If you've been dealing with erosion after heavy rains, you may be considering a French drain—but Colleen explains why they're rarely her first choice.
Common Problems with French Drains
Can damage tree roots during installation
Pipes may shift or break in clay soil
Tree roots clog perforated pipes
Standing water can attract mosquitoes
Repairs are difficult because the system is underground
💡 Stay tuned for the next episode, where Colleen discusses earthworks as a more sustainable alternative.
