Summer Tree Care Tips in Texas

Texas summers can be brutal, with sweltering temperatures and long periods of dry weather taking a toll on our beloved trees. Keeping your trees healthy during these challenging months doesn’t have to be overwhelming. With a little proactive care, you can help them thrive all summer long. From proper watering techniques to staying ahead of common diseases, here’s what you need to know.

Water Wisely

Texas heat saps moisture from the soil faster than you might think, so watering is critical. Trees need deep, infrequent watering to encourage healthy root growth. Instead of watering a little every day, focus on soaking the ground around the tree's root zone once or twice a week. Aim to give your mature trees 10-15 gallons of water per session, while younger trees may need more frequent attention as their roots are still developing.

Water early in the morning or late in the evening to minimize evaporation. If you’re unsure whether your tree is getting enough water, check the soil about six inches down. If it’s dry at that depth, it’s time to water.

Mulch for Moisture and Protection

Mulching offers a simple yet effective way to protect your trees from heat stress. Apply a 3-4 inch layer of organic mulch (like wood chips or shredded bark) around the base of your trees, but leave a gap of about six inches around the trunk to prevent rot.

Mulch helps the soil retain moisture while keeping it cooler during extreme heat. It also reduces weed growth, so you won’t have to compete with weeds for precious water resources.

Prune with Purpose

Summer pruning has its place, but it must be done carefully. Remove dead or damaged branches to improve airflow and reduce the risk of pests and disease. However, avoid heavy pruning in the summer heat, as it can stress the tree and expose sensitive areas to sun damage.

For young or newly planted trees, train them early by removing poorly positioned branches, but always prune lightly and with intention. If in doubt, consult with an arborist for advice.

Shield Trees from Heat Stress

Extreme temperatures can scorch leaves and weaken trees. Consider installing shade cloth for young or small trees that are more vulnerable. For larger, established trees, maintaining proper hydration and mulch will go a long way in shielding them from heat-related damage.

Watch for Common Summer Diseases

Texas trees are particularly prone to diseases like oak wilt and powdery mildew during the summer. Here’s how to recognize and manage these problems:

Oak Wilt: This deadly fungal disease affects oak trees, especially red oaks. Look out for wilting leaves that turn brown from the edges inward and rapid defoliation. Prevent oak wilt by avoiding pruning oaks from February to July, when the fungus is most active, and sealing any wounds promptly.
Powdery Mildew: This fungal infection looks like a white, powdery coating on leaves and is common in shade-loving trees like crape myrtles. It thrives in hot, humid conditions but can be managed by improving airflow through selective pruning and using fungicidal sprays if needed.
