Tree Disease Update:

The effects of the hail and heavy thunderstorms that seemed to arrive nearly every day in May will last long into the summer season.  Several diseases that are common in many of our ornamental landscape trees often become prevalent after hail storms.  Small cuts are formed in the twig tissue when hail crashes into the tree.  It is then very easy for bacteria and fungi floating around in the environment to infect the wounded tree.  Symptoms in the leaf and twig tissue will take a few weeks to become obvious, but by then it is too late to prevent stress to the tree.

Fireblight Bacteria, cytospora canker, leaf spot and, powdery mildew are a few of the diseases that will thrive in weather conditions that include heavy rain, hail, and high humidity. Symptoms manifest themselves in leaf tissue and can include necrotic spots, distorted leaf tissue, dead leaves, gummosis, and branch dieback. It is important to identify infections early and develop a plan to encourage a recovery in plant health. Treatments for diseases vary, and include trunk injections, foliar applications, modifying irrigation systems, pruning, and debris clean up.
