Top Tree Problems

1. Bacterial leaf scorch of oak
2. Hemlock Woolly Adelgid: One of the most common pests, these insects can cause the death of a tree if left untreated. They leave behind a telltale white wax and target primarily older trees.
3. Borers: Borers are attracted to unhealthy trees, burrowing in and laying eggs inside the trunk. The best defense against borers is to keep your trees healthy and unstressed.
4. Scale Insects: These insects target primarily hardwoods and conifers. Some signs of an infestation include abnormal leaf and shoot growth, yellow or red leaves, and branch gouting.
5. Anthracnose Disease: This fungal disease affects deciduous and flowering trees. Look for a spotting of foliage in spring and summer.
6. Winter Injury: Even during mild winters, evergreens can lose moisture and not be able to replenish it. Thus, make sure your evergreens have sufficient soil moisture.
7. Aphid Insects: Aphids are small and pearl shaped. An infestation can cause yellow discoloration and defoliation.
