Can I save my Rowan tree? - holes and spots problem
I've noticed a hole in the trunk of our Rowan tree. It looks like a
young tree, the hole is not too deep but is quite sizeable for the
trunk. I have poked around and some fine soil and a few black ants came
out which seem to run up and down the tree. I've noticed the Rowans
do tend to have peeling bark etc but I haven't seen one with holes.
Should I leave it and hope it heals or can it be patched?
To top it off I noticed a few silvery/ white spots on the leaves which may or may not be related. Any ideas of cause & treatment?
I am worried that the tree may be beyond saving & it is the only thing of interest in our garden at the moment!
Advice greatly appreciated. Thanks in advance, Della :-)
