They were topped 2-3 years ago and seemed to sprout new growth and looked fine.
In the spring this year 2 failed to come into leaf,these were the end ones in the row of 12 or so.
I just assumed the winter took them out.Now another 7-8 are going with loss of leaf,hollow bark and oozing of red/brown substance that has hardened.This is through the bark.
The trees are 15-20" diameter at chest height and 25 year old.
Any ideas please?
I showed the Boss's wifey today,she is not pleased having spent a fortune having them topped and now about to lose them.
