EAB Attacks the STL

Jul 25
Jul 25 2018
The EAB is in St. Louis Ash Trees We have spent the past week checking on our customer’s ash trees and we have observed adult EAB feeding activity in the upper canopies of ash trees in all areas of St. Louis.

What does this mean for you as an ash tree owner? If you have an ash tree and you live in St. Louis, it has been introduced to the Emerald Ash Borer.


This is what we have been planning for and anticipating for the past 10 years! If you have been treating your ash trees with MFS, your tree is protected. If your tree is due for treatment this year we will be coming around shortly to treat it.

As you may (or may not) recall, our treatment protocol has been to treat our customer’s ash trees using the non-invasive soil injections to begin with.  As the infestation mounts, we will need to begin the more aggressive treatment protocol. This involves drilling directly into the cambium of the tree and takes more precision, more time, a different product and skilled and knowledgeable arborists. We will be coming around to get updated measurements for trees that have grown and there will be price difference for this more intense treatment.

Some ways to tell if your ash trees may be infected with EAB: Suckering growth on the inner branches of your ash. Also known as water sprouts or epicormic shoots. These small upward growing branches can be seen on the inner branches and the lower crown of the tree Dieback at the top of the crown of the tree – you may start to observe some branches dying out in the top of the tree Feeding activity in the leaves. A very distinct patter of leaf feeding. Can be mild to severe. Major infestations on untreated trees will have major dieback and you will see bark flaking and woodpecker activity in the top of the crown.

If you have not been treating your ash tree, this is the time to start making a plan for removal. If you haven’t already, select a tree to plant to replace the ash tree that will inevitably begin dying off in the next 2-3 years. We are predicting that the peak infestation time will be upon us in the coming year and we will begin seeing a rapid die-off of ash trees.

Keep in mind – this is not our theoretical plan for treatment. It is proven to save and protect our beloved and valuable ash trees. Our friends and colleagues in the North: Michigan, Minnesota, Wisconsin, etc. have already been through their peak infestation and have seen millions and millions of ash trees decimated. For the ash trees that were saved and are still living there today, they were treated in the same manner and with the treatment protocol. Please call us if you have any questions or if we can help with anything else. We appreciate you allowing us to care for your trees!

Changing of the Guard at Metropolitan Forestry Services: Father Passes the Torch to His Daughter

Jun 6 2018

By Tamsin Venn

Meggan Hargrave started working at her dad’s office at Metropolitan Forestry Services in 2007 when a spot opened that he had a hard time filling. She answered phones, filed and placed work orders as temporary office manager. Managers came and went, so she started filling those roles as well, and it became more of an “operational everything” kind of position. Ten years later, she is not only settled in but poised to take over the business upon her father’s pending retirement.
