Oak Trees
Q.

Is It Really Scale?

Anonymous added on September 16, 2011 | Answered

Our very mature, historic oaks have bumps all over the leaves, almost pea size and brown in color. The tree leaves appear to be quite wilted. Is this scale? Will we lose our beloved old oaks? If possible, how can we treat it? We have lost 9 of these old historic oaks to the Oak Wilt that swept across our state in the past 5 years. Any advice is much appreciated.

I would recommend neem oil. It is very effective and safe for beneficial bugs as well as for humans and pets. Here is some information that may help:
