Our office has been receiving many calls about tree problems. The roller coaster of weather events has been very hard on our local landscapes. Last Friday I went to four locations for site visits and three of them were for tree evaluation. There are a number of issues happening due to many different causes. The ice storm of 2020, followed by bitter cold the following February, wet springs with excess water, to dry summers and even drought this summer and fall. Our landscapes are definitely stressed. With stress from the environment, our plants then become more susceptible to insects and disease (that sounds much like humans). So, there is not one answer I can provide, but feel free to reach out to me with questions.
