Description
All of the trees on State St. are dropping leaves at a rapid rate. Is anyone aware of what is causing this and what can be done to help the trees?

Do you have photos? Do you know what type of tree these are?

Hey Pam,
I am concerned about this too. They have never lost their leaves this early. Maybe URI can help.

A lot of rain led to a lot of growth very rapidly. Then the rain stopped. The trees needed more water to support all that new growth. They can drop leaves to adjust. Also, London Plane trees are susceptible to anthracnose but are resistant to it enough that leaves are lost but it does not kill the tree. It may kill off branches over time. Nothing can be done. Let nature take its course.

Thank you, Tree Hugger! I guess we can close this issue.

Thanks for the answer. Makes me feel better. I added the question and response to the Question and Answer database as well: http://seeclickfix.com/new-haven/questions/27-What-can-be-done-about-the-london-plain-trees-losing-their-leaves-and-dying

They're infected with anthracnose. The only practical control is to keep the leaves raked and bagged before each rain, since rainfall is the primary way of spreading the disease. [BTW, those actually are London Plane trees: a hybrid between Oriental & American Sycamore.] More here: http://www.na.fs.fed.us/spfo/pubs/fidls/anthracnose_east/
