[Mrs. Robinson]

Our huge oak trees with the moss hanging down is reminiscent of how we picture an old southern mansion, surrounded by these trees.

Unfortunately, the old, mature oaks with all that moss on them, can cause many of them to uproot.
The moss is heavy, particularly when wet, and some of these trees are virtually covered with it.
Heavy moss coverage is one reason an oak tree can blow over during a storm.

Most of it should really be removed because it does not permit light and air to penetrate through the canopy.
