Top 10 Tree Problems

Top Ten Tree Problems

1 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.

2 Lace Bug

Lace bugs target broad-leaf evergreens such as andromeda, azalea, and rhododendron. Early detection is the key to getting rid of an infestation. Look for yellow-silver stippling on the topsides of leaves.

3 Mites

Mites pose a serious threat to a wide variety of plants, and can seriously impact the visual appearance of a plant. Mites favor warm, dry climates, and are an extremely serious issue for many homeowners.

4 Tent Caterpillars

Caterpillars can weaken many trees and shrubs, increasing the chance of a secondary infestation. Look for silken, yellow cocoons.

5 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.

6 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.

7 Anthracnose Disease

This fungal disease affects deciduous and flowering trees. Look for a spotting of foliage in spring and summer.

8 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.

9 Weevil Insects

Weevils are commonly found on flowers and fruits. Look for notches around the edge of leaves.

10 Aphid Insects

Aphids are small and pearl shaped. An infestation can cause yellow discoloration and defoliation.
