I inherited a Bonsai and don't know much about it at all. The tag that came with it said Buddha Pine, but judging by the leaves and the pictures I see of Buddha Pine's I don't know that that ID is accurate.
Recently, my Bonsai has lost all it's leaves. I had it all winter on a window sill and it was generally happy - grew a lot of leaves (I inherited the tree in a bad state) and was generally well. Since the hotter weather has started, it has been less healthy. It was on the window beneath an AC system and I thought that might be the problem so I moved it into my bedroom on the windowsill. Bedroom has no AC, is generally hot and doesn't get much direct sun. I have put plant food pellets and checked the soil. It seemed very dry when I stuck a toothpick in to see how the soil was doing. I watered it well today, put it in a dish with some water on the bottom, and placed it back on the original windowsill.
Please help! This is a very important bonsai and I want to save it!
