I reside in Monmouth County New Jersey approx. 20 miles from the coast. I am hoping someone can offer some advice, as to my problem with my 32 year old weeping cherry tree. From what I can see from driving around, I am not the only person whose weeping cherry tress are suffering with this problem. Itâ€™s important to understand that nothing has changed in this area where the tree sits. I continually check it for bugs and fungus and up till last week, everything seemed fine. All of a sudden the tree is dropping leaves which are still green. I did not consider it a problem given the lack of summer rain this year. I thought it was just the tree trying to conserve. The leaves which have fallen show no signs of bite marks. There are also a number of full branches scattered throughout the tree, approx. 3-5 foot long which have turned black. The leaves are dark brown/black and also starting to fall. This problem seems to have showed up over night. I continually check the trees on my property and only in the last 7 to 10 days has this become noticeable. I had no idea I had lost so many leaves in such a short amount of time. This tree is the center piece of my property and sits in full sun. From first thing in the morning till approx. 5PM, it receives full sun. The treeâ€™s caliper is 57 inches, stands approximately 36 feet tall and 45 foot wide. It gets plenty of water from the sprinkler system which irrigates my lawn. My feeding and watering habits have not varied much in thirty years, so I donâ€™t think it has anything to do with over or under watering. The only change in chemical treatment for the entire property was that I used milky spore to rid my Japanese beetle problem. I was told that Milky spore powder will rid my property of grubs and leaf eating beetles. What can I do to stop this problem of dark brown leaves and leaves dropping like crazy? Can anyone think of a reason why the tree is getting hammered like this? I appreciate anyone who can offer expertise in dealing with this sought of problem. Please help.
