Hello. I have a Mountain Ash tree (I think) growing out of my patio. It has for the last couple of years seemed to have less foliage than before and some of the leaves show brown edges. I have had to cut off a number of smaller dead branches. It is a bit better this year but overall doesn’t look very healthy especially on one side. I have also noticed a few points where the bark seems to be missing but only small patches. If anyone has any insights or advice it would be appreciated. It has been there for a long time so I would rather keep it! Thank you.
