Now That My Ash Tree Has Been Treated, What’s Next?
Posted: 2019 | Emerald Ash Borer | Fall | Plant Health Care | Spring | Summer
Upon entering the United States in 2002, and the greater Wisconsin area in 2008, the Emerald Ash Borer (EAB) has affected over 35 states and killed hundreds of millions of trees. When you had your Ash tree inspected, and initially treated, you protected this vulnerable species from the EAB. This initial treatment, while proactive, is not the last step in ensuring the safety and longevity of your Ash tree.
Do I have to Treat my Ash Tree Every Year?
The answer to your question is dependent on the initial Ash tree treatment. If you called a Certified Arborist, your tree should be treated every other year. Certified Arborists typically use trunk-injected insecticides which contain emamectin benzoate, while products sold at your local hardware store may be similar, the treatment process and product used is what determines the effectiveness of the treatment itself.
This bi-yearly treatment will need to be continued for the forseable future and at least the next ten years.
Can I Treat my Ash Tree Myself After the Initial Treatment?
It’s important to understand the different products available. There are products sold within your local hardware store that are systemic insecticides and have been advertised as the “cure” to EAB. These insecticides are applied to the soil around the base of the tree. However, this method and type of product will typically not be effective until the EAB population numbers drop to a much lower number than currently being found in our area.
Continue Taking Preemptive Measures
While EAB is a threat, we at Wachtel Tree Science, encourage you to continue treating your Ash trees to ensure their safety and longevity. If you’re Ash has died during the EAB outbreak, consider other trees to plant such as, oak trees, musclewood trees, Kentucky coffee trees, and many more. Don’t hesitate to call regarding planting other trees, or the treatment of your current Ash tree by a Certified Arborist.
