What are elm tree injections?
A. Fungicides are injected into the root flare area of healthy elms to prevent the Dutch elm disease fungus from establishing in your tree. Although tree injections are expensive and must be repeated every few years, injections can be an effective preventive treatment of Dutch elm disease. Injections are most effective when the leaves reach full size in early summer. Injections should be done by a professional tree care service to guarantee proper application procedures. Several fungicide products are registered for elm tree injections.
