I have a Salix integra, which is about 2 months old. It started off fine but now it has a lot of black dots running up the middle of the green leaves and the white/pink leaves are going brown and dry. It is on the patio near the house and gets about 4-5 hours of sunlight. I bought this as a birthday present to myself. I really do not want it to die. What can I do? Please help.

Most likely a black spot fungus.
Neem Oil is a good treatment.
