Returned from a week away and found that most of the oaks had dead leaves - like the whole tree at about 2/3's leaf out were dead and dried up. Big ones, little ones but not everyone???? My first reaction was that some sort of disease was getting them because it was only the oaks. A few days later new leaves have begun to develop and speaking with my friend it turns out we had a little frost last week. I am assuming all will be well but this may effect fruit production for my deer. Anyone else in Mid- Michigan see this with oak trees?
