Q.I have a yellow powder type of fungus on my miniature willow tree ( sorry, don’t know the real name)… can you help?
Photo attached. There is a yellow powdery growth on the leaves and stems of our dwarf tree … can you identify and tell me what I need to do to get rid of it? Please .

This is a rust fungus! They can be easy to get rid of, though. Dispose of what you can, then treat with a fungicide.
