Thank you for the fine work on our Cedar Elms. All the mistletoe is gone and your crew left the yard so clean, you can’t even tell they were there. Thank you again. ” - Tom D.
Tree Disease and Insect Control
Most tree problems caused by disease or insects can be avoided. Each tree has defined stages of maturity and each stage has specific needs that must be met to ensure healthy development. Common to all stages is the necessity to avoid damaging the tree’s life support system: the roots, the branches, the leaves and the bark. A tree that is in good health obviously has a better chance of surviving the ravages of certain insects or diseases than one with weakened life support systems.
It is our belief at Preservation Tree Services that prevention of injury and disease is vital to ensuring your tree’s survival into a healthy old age. Over-watering is one of the most common forms of injury to trees. Over-watering is never intentional. Most of us don’t know the proper frequency and amount of water required by each species. Sometimes over-watering is done in a passive fashion—by lack of proper drainage. When the soil around the root system fails to dry, rotting of the roots can occur. This damage weakens the tree, and allows opportunistic diseases to attack and sometimes kill the tree. As we work with you, we will teach you the correct method of watering your trees. We may also recommend correcting poor drainage conditions that allow a tree to sit in soggy soil.
A lack of variety of different tree species in an area contributes to the spread of diseases. Many established urban forests were devastated because only a limited number of species were planted, allowing species-specific diseases an easy means of proliferation. Experience shows it is healthier for trees to be planted among a variety of other tree species just as occurs in nature. By preventing potential problems, it is also more economical.
Trees provide a home for a variety of insects. Most are harmless. Some are just unsightly. Some are beneficial. There are, however, certain insects whose presence should be cause for alarm and immediate response. Carpenter ants and termites, for example, are indications of dead wood under the bark. They aren’t causing the damage, rather they are there because the damage is already present. They are an outward sign that something is wrong with the health of the tree.
Some insects like the Elm bark beetle cause damage by introducing disease. Others, like the Tent Caterpillar, can eat all of the foliage on a tree. Borers cause damage to the bark and capillary systems of the tree, leaving a sap-oozing opening where other insects can invade.
Parasites for trees aren’t just limited to insect life. Some parasites are also plants themselves. Fungus growth on a tree, especially at the base, might be cause for concern. A tree that has mushroom -like growths around its base may be in serious trouble. Mistletoe is another common plant parasite in our area. It depletes the tree’s nutrients, thereby causing stress on the tree, a condition that threatens the overall health of the tree.
We always try to use organic, natural and Eco-friendly treatments to support your tree's health. In the event that we have to use a conventional treatment, such as with oak wilt, we use an innovative Arborjet system that allows us to keep the treatment contained within the tree - never broadcast in your environment.
