We recently moved into a brand new property in central mass. It has a number of oaks on the lot and today I noticed the leaves on one of them were brown. This tree is a pin oak (I think: 6 pointed leaves and
3 points on each) and is about 40 feet tall.I picked up a leaf that had fallen and it had gone completely brown from the tips to about a third of the way back where it was still green.
I am a neophyte to trees and their diseases and the only thing I could find on the web that matched my leaf was "oak wilt". However, a distribution map did not show it to be present in MA.
By the way, and I realize this might be important, this tree has grown on the lip of a natural depression. The builders in their wisdom have filled this depression with excavated dirt. It is not piled against the tree, but I guess it may be a sufficient change in the dynamics of the root system to perhaps cause a problem.
I realize my next call should be to an aborist, however would be interested in some feedback from experienced folks.
Thanks in advance,
Gary
