The leaves on my umbrella tree have been turning completely black and whole umbrellas falling off. This was 2 months ago, the plant now has only 1 or 2 leaves left. I donât know what happened to her, I tried to do some research and it said some kind of bacterial infection so I cut off the infected leaves and sprayed her with diluted peroxide and in the soil. Is there any way to revive her? Should I snip branches off and hope for regrowth? Any thoughts to what happened?
