I received a bonsai tree from a local department store here in Michigan for Valentines day, and it looks to be on the brink of death already. The tag on the tree never mentioned anything about what kind of tree it was. It said to keep it in indirect light, and that was about it. The soil type is hard to determine. Rocks sit on top, and feel to almost be glued together. There is a drainage hole in the bottom where I can see dark, moist soil when I look up it.
When I first got the tree, almost all of the leaves were soft and green except for a few that were dried and brittle. I took the tree to work and began to notice more and more of the leaves growing dry and brittle, as well as developing white spots on the leaves.
I began to water it more frequently as I saw the leaves getting more dry. I would water the plant, and could hear it trickling through the pot and coming out through the drainage hole, so I thought at the time that the soil didn't whole water very well. When I started noticing the white spots, I applied some fungicide with a spray bottle to the leaves.
It's been a little over a week, and all the leaves are dry and brittle and have the aforementioned white spots. Without knowing what kind of tree this is, is there anything I can do to save it?
