I recently purchased a Fukien Tea tree on the internet and I am really new to this whole bonsai stuff this being my first tree. I noticed on the tree when I got it there was dirt like stuff on the leaves that would come off if i rubbed it, also I noticed black things under the leaves and again would rub off. I am a little concerned for my tree and have been searching all over the internet for some kind of explanation as to what the heck these things are, i did look in the forum and could not find anything. If anyone has a clue as to what is going on with my tree that would be greatly apprecaited if you could tell me if I should be conceded and/or how to fix it. Thanks
