In San Diego, some of the most common tree pests and diseases include Southern American Palm Weevil, Bark Beetles, and Sudden Oak Death. Here are signs and symptoms of how these pests and diseases can affect your trees. 

• Southern American Palm Weevil: Signs of palm weevil infestation include crown flattening, yellowing foliage, pupal cases on the ground, and holes, tunnels, or frass near frond bases.
• Bark Beetles: Canopy thinning, branch dieback, exit holes, and frass signal a severe bark beetle infestation, often leading to tree death. Healthy trees resist attacks, while stressed trees are most vulnerable. 
• Sudden Oak Death: Sudden Oak Death causes dieback and tree loss, with early signs like cankers, leaf spots, trunk oozing and foliage loss.

A Plant Health Care (PHC) Program is a proactive, year-round plan to keep your trees and shrubs healthy and pest-free. Our certified arborists focus on prevention and early detection by monitoring soil health, nutrients, insects, and disease. Based on your property’s needs, we create a customized care plan that may include fertilization, pest management, pruning, and soil improvement. 

While coastal tree issues in San Diego often focus on salt tolerance, high humidity, and fog, inland tree problems lean toward drought tolerance, fire risks, and soil compaction. 

Some tree species, like birch, sycamore, silver maple, and redbud trees, naturally shed bark as they grow, while other species shed bark as a sign of disease, pests, or extreme temperature damage. If your tree has healthy-looking bark under the shed, then it’s usually safe. Read our blog to learn more about bark shedding.
