Ash trees are a common sight in many neighborhoods and parks in Dane County, Wisconsin,
and for good reason. They are hardy, resilient, and provide a beautiful canopy of green in the
summer. However, in recent years, a new threat has emerged that poses a serious danger to
these beloved trees: the emerald ash borer.
The emerald ash borer is a small, metallic-green beetle that is native to Asia. It was first
discovered in the United States in 2002, and since then, it has spread rapidly, infesting ash
trees in more than 30 states, including Wisconsin. The larvae of the beetle feed on the inner
bark of the tree, cutting off its ability to transport water and nutrients. This leads to the tree's
death in as little as two to four years.
If you suspect that your ash tree has been infested with the emerald ash borer, it's important to
take action immediately. The longer you wait, the harder it will be to save your tree. At Keyman
Lawn Care, we understand the importance of protecting your ash trees, and we are here to
help.
Our team of certified arborists is trained to identify the signs of an infestation and to provide the
appropriate treatment. We use a combination of methods, including insecticides and thorough
inspection, to protect your tree from the emerald ash borer.
The first step in the treatment process is to determine the extent of the infestation. We will
inspect the tree for signs of damage, such as D-shaped holes in the bark, serpentine galleries
under the bark, and branches that are dying or dead. If we find evidence of an infestation, we
will recommend treatment options to you. If your tree has damage that is irreparable, we would
recommend to have the tree removed.
Insecticides are the most effective way to protect your ash tree from the emerald ash borer. We
use a systemic insecticide that is absorbed by the tree and transported to the branches and
leaves, where it kills the beetles. This method is both effective and safe, as the insecticide
works from inside the tree so it will not harm pollinators, pets, or humans.
Our team will also recommend that you keep an eye on the tree after treatment, and schedule
follow-up treatments as needed to ensure that the ash borer beetles are fully controlled. Once
treatment is applied, the follow up treatment would be every two years after the initial.
Another important step in protecting your ash tree is to maintain its overall health. We will
recommend fertilization, irrigation, and other cultural practices that will help your tree thrive.
