Q.My Hawthorn (Rosea Flore Pleno) Is Covered In Lichen

Zone Scone, Perth and Kinross, Scotland | Anonymous added on March 12, 2021 | Answered

I wonder if there is treatment available to help this tree? It is planted in a stoney area and has been a bit poorly for a couple of years. All the branches are covered in tufts of Lichen. Sorry I can’t send a photo but hope you can give me some help.

Lichens and trees most often enjoy a symbiotic relationship. However, if there is a noticeable overgrowth of lichen, it may mean that the tree is either under some kind of distress or that it is simply very old.
You may want to consider moving the tree to a different location. Here's an article about the best conditions for growing Hawthorns: https://www.gardeningknowhow.com/ornamental/trees/hawthorn/growing-hawthorn-trees.htm
