Trees are a vital part of any landscape, providing shade, beauty, and even increased property value. In Abilene, Texas, where the climate ranges from hot summers to chilly winters, maintaining healthy trees is a year-round challenge. One of the biggest threats to tree health in Abilene is disease. Early detection and treatment are key to saving infected trees and protecting the overall health of your yard. In this article, we’ll explore the top five tree diseases affecting Abilene yards—and how to spot them before they cause serious damage.
- Oak Wilt
Oak Wilt is one of the most destructive tree diseases in Texas, and Abilene is no exception. It primarily affects red oaks and live oaks, spreading quickly through root grafts or beetle activity.
Symptoms:
- Sudden leaf discoloration (from green to brown)
- Leaf wilting and drop, especially in late spring or summer
- Fungal mats under the bark (in red oaks)
- Branch dieback from the top down
- Hypoxylon Canker
This fungal disease is a silent killer, typically affecting stressed or drought-weakened trees like oak, pecan, elm, and sycamore—common species in Abilene yards.
Symptoms:
- Bark sloughing off to reveal dark brown to black fungal crust
- Leaf thinning and stunted growth
- Rapid tree decline once symptoms appear
Early Detection Tip:
Inspect bark regularly. If you notice pieces peeling away or unusual black or silver patches beneath, call a certified arborist immediately.
- Fire Blight
Though more commonly associated with fruit trees, Fire Blight also impacts ornamental pear and apple trees—both popular in local landscaping.
Symptoms:
- Sudden blackening of blossoms, twigs, and leaves (as if scorched by fire)
- Oozing of a sticky, amber-colored substance from branches
- “Shepherd’s crook” bending of branch tips
Early Detection Tip:
Check during spring bloom for wilted blossoms or curling branch ends. Prompt pruning of affected areas helps control the spread.
- Bacterial Leaf Scorch (BLS)
Often mistaken for drought stress, Bacterial Leaf Scorch is a chronic condition affecting oaks, sycamores, and elms—trees commonly found in Abilene’s urban landscape.
Symptoms:
- Marginal browning of leaves starting in mid to late summer
- Yellow band between green tissue and scorched edge
- Premature leaf drop and canopy thinning
Early Detection Tip:
Watch for patterns—affected trees will often show the same symptoms year after year. A professional diagnosis via leaf sample testing is essential for proper treatment planning.
- Root Rot (Phytophthora)
This soil-borne pathogen thrives in poorly drained soil conditions, attacking a wide variety of tree species from the roots upward.
Symptoms:
- Stunted growth and sparse foliage
- Yellowing leaves and premature drop
- Mushy or discolored roots upon inspection
Early Detection Tip:
If your yard has heavy clay soil or poor drainage, monitor your trees closely during rainy periods. Any signs of root weakness should prompt an immediate soil and root inspection.
Why Early Detection Matters
Catching tree diseases early not only improves the chances of saving the tree but also prevents the disease from spreading to other trees in your yard or neighborhood. Abilene’s mix of native and ornamental trees means disease management must be tailored to both the species and the environment.

Understanding the signs of these top five tree diseases can empower homeowners to act quickly and call in professionals when needed. Regular inspections, proper pruning, and adequate watering are foundational practices that go a long way toward disease prevention.
