I am living in Appleton, WI and I planted a new lingonberry bush this spring. It was doing very well until we got into the pattern of insane amounts of rain (we are at least 9 inches above normal over the since June 1st. Water pools in the yard with rain right now due to the saturation) It is near our house, so it gets full sun only in the afternoons. In the past few weeks the leaves have been turning brown. It has progressed to the point where only 1/3 of the leaves are still green.
I also have young sugar maple exhibiting brown spots on the lighter green new growth leaves, while the old growth dark green leaves are fine. In addition, one of our lilac bushes has dying leaves as well (It typically was very healthy, if sparse leave wise). Any thoughts or suggestions?
