Weeping Cherry Tree leaves are brown and are not falling off. I will treat it for a fungus i the Spring. Should I take the leaves

Question

the brown leaves off?

Answer 1

You can treat in spring, but it would be a good idea to treat now, also, with dormant oil. This can help stave off some of the infection and make it easier to treat in the spring.

The leaves should fall off by themselves as the new leaves start coming in, but if they don't on their own, then it can be fine to do so manually.
