Pomegranate tree has yellow fungus/lichen on the branches. What is this? Is it sick/dying?
Hi there, we just a received a young pomegranate tree (approx 3yrs old). However, we have notice that all over the branches and particularly where they join, there is are patches of yellow growth, that look like lichen or mould. Can anyone tell me what this is? What causes it, and how to heal the tree? Thank you so much.
This is not generally harmful, but I would try increasing air circulation around the tree.
