Yesterday, I had gotten a Ginseng Ficus Bonsai. Now I know, a small plant in a pot is not considered Bonsai, but I still consider it Bonsai, and I want to take good care of it. I have attached some pictures below. There seems to be some kind of green material growing on the trunks of my tree. I am not sure if it is fungi or not. Also I have problem with pests as some of the leaves have holes in them ( only a few) and I've seen an insect walking around while I was watering it the day I had bought it. Also the roots attached to the soil seem weak; I can move the tree; it is not sturdy. I don't know if my tree will be able to last long. I haven't found any helpful articles online yet, but I hope you guys can help me out. Thanks for reading!

Hello, and welcome. Dont want to bug you but, can you tell what makes you still consider as Bonsai?

I still consider it a Bonsai because the species of tree itself has large, fat trunks that resemble ancient trees. The leaves however, I consider them to be pretty average

These are exposed roots of Ficus Ginseng, not trunks. There are no trunks in nature that look this way.

Oh, I did not know that. Thank you for the info. Do you know how I could get rid of these pests and perhaps the green stuff on the roots?

Hello.
Many insects are not pests, in fact some are helpful for potted plants.
To get rid of the green stuff, use an old toothbrush and clean the roots.
Good luck with your houseplant.
