Phomopsis Red Flags

• Darkened or discolored bark near affected areas

What is Phomopsis?

Phomopsis is a fungal disease that affects a wide range of woody trees and shrubs, especially when they are stressed by drought, site disturbance, or other environmental challenges. Weakened plants are more susceptible to infection and may show symptoms sooner.

Early signs often include subtle browning of leaves and new shoots. As the disease progresses, leaves may curl and discoloration becomes more noticeable. Because these symptoms resemble drought or heat stress, Phomopsis is often overlooked at first. A key difference is that damage usually starts at the tips and edges of young growth and slowly moves inward, leaving tissue dry and brittle.  

How Texas Tree Surgeons Diagnoses and Treats Phomopsis

Managing Phomopsis starts with early identification, an accurate diagnosis, and proper tree care practices. Removing affected growth and reducing stress on the tree can slow disease progression. While Phomopsis can be difficult to eliminate once established, consistent maintenance helps limit its impact.

What can Homeowners do to Help Their Trees with Phomopsis?

• Prune affected branches promptly
• Disinfect pruning tools between cuts
• Avoid pruning during wet weather
• Improve air circulation with proper plant spacing
• Keep trees healthy with proper watering and care
• Monitor trees regularly for returning symptoms

If symptoms continue to spread or your tree’s health declines, contacting a certified arborist is recommended. A Texas Tree Surgeons ISA Certified Arborist can provide an onsite evaluation, help confirm a diagnosis, and recommend practical care options tailored to your tree and property.
