Top Ten Tree Problems
- 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.
- 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.
- Tent Caterpillars:
Caterpillars can weaken many trees and shrubs, increasing the chance of a secondary infestation. Look for silken, yellow cocoons.
- 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.
- 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.
- 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.
- Anthracnose Disease: This fungal disease affects
deciduous and flowering trees. Look for a spotting of foliage in spring and summer.
- 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.
- Weevil Insects: Weevils are commonly found on flowers and fruits. Look for
notches around the edge of leaves.
- Aphid
Insects: Aphids are small and pearl shaped. An infestation can cause yellow discoloration and defoliation.
