Hello again all. A week or so ago I decided to purchase a Hawaiian Umbrella bonsai via amazon, through Brussel's Bonsai. The reviews were mixed, and some had mentioned seeing bugs on their plants. (I only read them after I'd purchased, unfortunately) Mine was delivered today, and I decided to open it outside, away from my other plants. Lo and behold: yes, it does have bugs. I was semi-prepared for that. What I was not prepared for was the odd discoloration on the tree. The trunk looks like its covered in something black, and I can't seem to find any more information online about it. It *seems* like it might flake off, as there are black flakes on the tape below. The tree overall does not look very happy, unlike some other trees I saw posted on their reviews. I have already begun treating for the bugs, but I'm confused about the trunk. In my situation, what would you do? I feel like sending it back, but almost feel it's not worth the hassle. I'm going to try and get a refund regardless. As for the trunk/bugs, is it worth the struggle of treating? PS-- I would have posted a pic of the entire tree but for some reason the site isn't letting me upload that one.
