Recommended annual chemical treatments for an American Elm
We pay a tree service annually for chemical treatments to maintain and protect a 60 year old American Elm on our property. Their recommended treatments are costing us a small fortune, close to $500/ year. Between the treatments and pruning, I’m ready to stop maintaining this tree and let nature take its course (like my neighbors). Is there some minimum recommended chemical treatment we can provide without breaking the bank, but still protecting the tree?
While you don't specify the disease you are preventively spraying to control in your American elm, we are assuming it is Dutch Elm disease. If this is the case, there are several factors to take into consideration. How close are your neighbor's trees, are the neighbor trees already diseased, etc. If the trees are in close proximity the fungus can travel to your tree via root grafts. We suggest you obtain a consult from one or more certified arborists to get a professional opinion after inspecting your tree. It would also be prudent to get several bids to see if there are other, more cost-effective chemical treatment options available to help you make an informed decision to continue or discontinue your current chemical treatment plan.
