Q.What Is Wrong With My Willow Tree (salix Capra Pendula)
I noticed this morning a yellow fuzzy growth on a lot of my willow leaves. When I looked closer to looked like there were yellow spots up the trunk. The base of the tree also appears to be breaking down? What can I do to fix this?

Your tree likely has several things going on. The yellow-orange could be leaf rust, a common fungal infection of willows. The black at the base of the tree could be a canker. I would consult an arborist as soon as possible for the best way to treat multiple infections.
