Why are my Maple trees leaves turning brown, dropping and then the branch dies? My neighbors and friends have the same thing happening on their properties. My neighbor lost a beautiful full grown tree in less than a year. My fully grown tree is getting very sparse with the leaves. Can anything be done to reverse or stop the process? – Bob, S. Chelmsford
I’m curious about the maple tree fungus that seems to be on all the maple trees in Mass. The leaves are now turning brown and falling off long before they should. – Carolyn, Berlin
Well Bob & Carolyn, we asked Bob at Pemberton Farms in Cambridge about this and here’s your answer:
Stress Stress Stress! That is the only way to describe why many of our favorite trees look the way they do now!
The 2011 growing season has had more than it’s fair share of extreme weather conditions. Starting in April and continuing each month even through this weeks extreme amounts of rain our plants and trees are showing the effects of all this adverse weather. One of the most notable effected by this is one of the most common trees, The Maple Tree.
Heavy rains followed by extremely hot and dry times, back to heavy rain and high levels of humidity have caused maples and many other trees to be more susceptible to diseases, insects and other adverse issues. The worse many have seen in years. Foliage turning brown and dropping, autumn colors appearing now and branches dying off all are all found in trees that are in a weaker than normal state. Insects and diseases are also more common when trees are stressed. One of the more common issues is the maple bladder gall. Unfortunately this time of year there is not much you can do to help stop this from occurring. I would suggest that when all the foliage falls from your trees later this fall that you make sure you remove all the leaves as many diseases will stay on the dead foliage and the spores can re-emerge next spring.
Hang in there. Maple trees are very resilient, all should be fine for next season.
