At this point if you watch the news or read the paper or garden magazines, chances are you have heard of Emerald Ash Borer. The Emerald Ash Borer (EAB for short) is a small, metallic, wood boring beetle that has spread throughout the US. The attack Ash trees by tunneling into their vascular cambium (the inner bark that trees draw water up with). The result? Strands of Ash trees becoming defoliated (loosing their leaves) and dying out. What can you do to protect your Ash trees? The Arborjet system may be able to help. Starting last spring we at Hillside Garden Center are offering this service. Here I will explain what is involved and what else the Arborjet system can treat.
Arborjet is a proactive solution by injecting an insecticide deep into the tree. The tree then takes the insecticide up through the trunk and into the leaves. When an insect tries to bore into the trunk or eats the leaves it will be killed. Uptake of the formula is fastest in spring once the tree has fully leafed out and developed a full canopy. This will prevent adult beetles from laying eggs in the tree. Treatment in the summer will kill any larvae that have emerged. Treatment in the fall can give a head start on next season. Each treatment will last about 2 years.
The product is safe for families and pets as it is contained to within the tree. Injection sites are then “plugged” so that the insecticide stays within the tree. Hillside can provide an estimate for an Arborjet tree injection at your residence. Don’t know if you have an Ash tree? We can provide a landscape consultation – contact our landscape design staff for questions and estimates.
What else can Arborjet do? Treatments are also available for other pests such as the Asian Long-horned Beetle (another borer beetle) and the Hemlock Wooly Adelgid (a sucking insect that attracts the bases of twigs and needles on Hemlock trees). It can also treat tree diseases such as Sudden Oak Death, a disease similar to a fungus which causes bleeding cankers and defoliates the tree. Anthracnose is a fungus that winters on twigs and attacks new buds and shoots the following year – Arborjet has a solution for that too.
If you are experiencing an issue with your trees that best thing is to have an expert such as Hillside take a look. They will identify the problem and let you know the best possible treatment before moving forward. With Arbor Day approaching it is a great time to take a walk outside and evaluate the health of your trees.
