Treating Ash Trees

There are an estimated 87,000 ash trees in Sioux Falls and if you have any on your property and you want to treat them, Jason Bofenkamp of Arbor Care shows us how he does it. 

The process is drill, plug and inject.  There are particular areas on the tree that you choose to drill holes that are more conducive to uptake; they are called root flares.  

You start by drilling a hole, then you put a plug in that hole.  After that you inject a needle into that plug.   It takes about eight holes and eight injections to properly protect an ash tree.  It takes a few minutes to unload the bottle of pesticide.  

Then within 72 hours, the tree should be fully treated as the pesticide travels up through the tree's vascular system.  This process has been used in large metropolitan areas with about 100 percent accuracy.
