Protect Your Trees Before It’s Too Late
Trees in Texas face unique challenges due to extreme heat, drought conditions, and aggressive pests. In San Antonio, these conditions can weaken trees and make them more vulnerable to disease and parasite infestations.
Recognizing the early signs of tree problems can help you take action before serious damage occurs.
🌿 Quick Answer: What Are the Most Common Tree Diseases in Texas?
Some of the most common tree issues in Texas include:
✅ Oak Wilt
✅ Bacterial Leaf Scorch
✅ Root Rot
✅ Aphid Infestations
✅ Webworms
✅ Tree Borers
Early detection is key to saving your trees and preventing the spread of disease.
Oak Wilt (Most Serious Threat in Texas)
Oak wilt is one of the most dangerous tree diseases in Texas and can spread rapidly between trees.
Signs of Oak Wilt:
✅ Leaves turning brown from the edges inward
✅ Sudden leaf drop
✅ Rapid decline of the tree
Oak wilt can kill a tree in a matter of weeks or months, making early intervention critical.
Bacterial Leaf Scorch
This disease affects the tree’s ability to transport water and nutrients.
Symptoms:
✅ Leaf edges turning brown or yellow
✅ Leaves appearing scorched
✅ Gradual decline over time
While not always immediately fatal, it weakens the tree and makes it more vulnerable to other issues.
Root Rot
Root rot is often caused by overwatering or poor drainage.
Signs:
✅ Mushrooms or fungal growth near the base
✅ Soft or decaying roots
✅ Tree instability or leaning
This condition can severely weaken the tree’s structure.
Aphids (Common Tree Pest)
Aphids are small insects that feed on tree sap and multiply quickly.
Signs:
✅ Sticky residue on leaves (honeydew)
✅ Presence of ants
✅ Curling or distorted leaves
Aphids can weaken the tree and attract other pests.
Webworms
Webworms create visible webs in tree branches and feed on leaves.
Signs:
✅ Large web-like nests in branches
✅ Missing leaves around webbed areas
While often cosmetic at first, heavy infestations can stress the tree.
Tree Borers
Tree borers are one of the most destructive pests because they attack the inside of the tree.
Signs:
✅ Small holes in the bark
✅ Sawdust-like material near the base
✅ Weak or dying branches
If untreated, borers can cause severe structural damage.
Why Trees Become Vulnerable
Most diseases and parasites affect trees that are already stressed.
Common causes include:
✅ Drought and heat stress
✅ Poor soil conditions
✅ Over-pruning or improper care
✅ Damage from storms
✅ Lack of regular maintenance
Healthy trees are far more resistant to pests and disease.
Signs Your Tree May Be Infected
Watch for these early warning signs:
✅ Discolored or spotted leaves
✅ Premature leaf drop
✅ Dead or dying branches

Catching these signs early can make a major difference.
