Several months ago, I saved a dying dieff from my neighbor's trash. It has since put out a lot of new growth, and a lot of curled up leaves that have yet to open. Unfortunately, looking at it today, I noticed what I believe to be mealy bugs all inside the curled up leaves. Any Ideas as to how to get them gone? It's also got a lot of what looks like large white dust particles in the same areas, as well as small black particles. Any clue what those are? Thanks for any help in advance.
