Do you think you tree is sick or infested. How would you know? Can you tell if your tree is infested with insects or larva like the emerald ash borer larva? Do I need to cut down my tree and have the wood removed or can we have the tree be trimmed. These are all good questions.
Below is a general list of tree problems, of sick trees, that tend to be in the Naperville area.
Dutch Elm Disease: This disease causes the bark on the tree to turn grayish and causes the tree leave to wither.
Lace Bug: Detecting this disease early is the key for treating trees. This disease, or the lace bug, favors large and broad leaves. Trees in the area affected can be azalea, rhododendron, and Andromeda. One way to tell, early on, if the plant has lace bug is if the top of the leaves have a yellow silver stippling.
Aphids (insects): An aphid infestation may cause the tree to loose leaves and/or a yellow discoloration of the leaves.
Mites: Mites are a particular problem. They threaten a large variety of plants and destroy the well-being and appearance of the plant or tree.
Weevils: Insects described as weevils are common on fruits and flowers. Evidence of weevils will show in notches at the edge of the plant leaves.
Tent Caterpillars: You probably have seen these and wondered if there are big spiders. You would have seen a silk web in the branches and yellow cocoons in the web. These are creepy and make my skin crawl.
Borers: Ash borers and other borers attack and kill trees that are unhealthy. Usually beetles, such as the ash borer, will attack the tree and lay eggs in the tree trunk. Larvae will hatch in the spring and eat away the trunk of the tree under the bark. Keeping your tree health is the best defense of these insects. A sick or tree in dangers can be injected to tree and protect against these borers.
Winter Damage: Trees can be damaged during winter for many reasons. Conifers or evergreen trees are prone to damage. Evergreens or conifers can lose water during winter and desperately need more. Keep in mind to water your trees. Proper soil moisture is necessary not only with evergreens but with all trees.
Hemlock Wooly Adelgid: These insects target older trees and are very common. If not treated these insects will kill your tree and you will need to have your tree removed. A waxy residue is a sign of their presence.
Anthracnos Disease: This disease is a fungus that affect trees that flower. Signs of this is leaves that are spotted in the summer and spring times.
Scaling Insects: These insects like both conifers (pines) and hardwood trees. Insect infestation is noted by abnormal leaf growth, shoots and leaves at the base of the tree (common with ash borer), branches that show gouting and leaves that are either yellow or red.
Black Knot: Black Knot is a fungus that attacks fruit trees. Black knot is a fungal growth on the branches of the tree. Trimming the tree before the tree has leaves in the spring is the easiest treatment.
