It is happening again. Like last spring, one of our ash trees buds
out nicely, starts to leaf out but then the immature leafs start
dropping off. It has happened before but not to the extent that it
has the last two years. Last year, almost all the leaves fell off.
In the past, some leaves dropped but not to a significant amount.
Also, in previous years, the leafs would turn dark and roll up before
dropping. Now, they just drop.
