Rowan tree not looking healthy
For several years now my rowan tree hasn't really grown. It still produces leaves and berries, but these are very small. It now also has several holes/gashes in the bark on the trunk. We had someone look at it but they weren't sure what was wrong and just removed a couple of small dead branches. I haven't been able to find anything online that seems to match this and wondered if anyone had any ideas and if it is treatable - or beyond saving. The tree is about 30 years old and of great sentimental value, being planted by my late father and the offspring of a tree from my childhood garden.
