When the trees start changing colors, it’s a time of year where we create time to stop and take in the beauty of nature. It’s also a time where we can provide the care to the trees to ensure their health in the seasons to come. There are a number of diseases here and more creeping in that pose a threat to our trees. WEMU's David Fair discussed the challenges and what to do about it with Washtenaw County Conservation District community forester, Matt DeJonge.
