Hello Everyone!
I had a Japanese maple dropped into my lap and it was in terrible condition! The bark seemed to be peeling off near the nebari and also looked blackish. I took it out of the pot and washed off the roots with water and notice there were still some roots that were alive and seemed to be healthy and I took a page out of Peter Chan book and placed it in a nursery pot full of sphagnum moss. I've been online researching trying to narrow it down but it had been difficult. I did come across hydrogen peroxide rinse to help fight of bacterias and fungus. any advice is this method safe?
