This guide will help you identify and manage some of the most prevalent tree diseases in Gilbert, Tempe, Chandler, and Mesa.
Recognizing Common Tree Diseases in the East Valley
- Anthracnose
Anthracnose is a fungal disease that affects many tree species, causing leaf spots, defoliation, and twig death. It is particularly prevalent in sycamores, oaks, and maples.
Symptoms:
- Irregular brown spots on leaves
- Early leaf drop
- Cankers on twigs and branches
Treatment:
- Prune and dispose of infected branches
- Apply fungicides during the growing season
- Improve air circulation around trees by proper spacing and pruning
- Powdery Mildew
Powdery mildew is another common fungal disease that affects a wide range of trees, including oaks, maples, and elms. In addition, it appears as a white or gray powdery coating on leaves, stems, and buds.
Symptoms:
- White or gray powdery spots on leaves and stems
- Distorted or stunted growth
- Premature leaf drop
Treatment:
- Remove and destroy infected plant parts
- Ensure adequate spacing and air circulation
- Apply fungicides specifically labeled for powdery mildew
- Verticillium Wilt
Verticillium wilt is a soil-borne fungal disease that affects the vascular system of trees, leading to wilting and dieback. It is commonly found in maple, ash, and elm trees.
Symptoms:
- Wilting and yellowing of leaves
- Dark streaks in the wood under the bark
- Branch dieback
Treatment:
- Prune affected branches to reduce disease spread

Treating Tree Diseases in Gilbert, Tempe, Chandler, and Mesa
- Proper Pruning Techniques
Tree pruning is essential for maintaining tree health and managing diseases. Remove dead, diseased, or damaged branches to improve air circulation and reduce the spread of pathogens. In addition, make clean cuts just outside the branch collar and avoid leaving stubs.
- Regular Inspections
Regular tree inspections help identify diseases early, allowing for prompt treatment. Also, look for signs of distress such as discolored leaves, wilting, or unusual growth patterns. Early detection can prevent severe damage and tree loss.
- Soil Health Management
Healthy soil promotes strong and disease-resistant trees. Of course, ensure your trees receive adequate water and nutrients. Also, mulch around the base of trees to retain moisture and regulate soil temperature. In addition, avoid excessive fertilization, which can lead to nutrient imbalances.
- Using Fungicides and Other Treatments
In some cases, chemical treatments like fungicides may be necessary to control tree diseases. Furthermore, always follow the label instructions and consult with a professional arborist before applying any chemicals to ensure safe and effective use.
