Firstly hello everyone im new to this forum.
I have an issue with a Chinese elm my parents own. I repotted the tree at the weekend and noticed a strange fungus/rot/scale on the trunk?
Can anyone tell me what it is? and how to cure it?
History of tree:
14+ years old, Watered Daily when needed, Kept indoors, Drainage in old pot was poor hence new pot.
Help would be greatly appreciated, hopefully it will get better.
