Hi guys,
I'm new to bonsai. I have a Chinese elm that someone bought for me from Amazon. Unfortunately, the leaves are kinda big and don't look like I want them to. I would like them to be small in tightly packed clusters. I've uploaded a photo of my bonsai and the Chinese elm I admire. Is it possible to get it like that? Or are they just different trees.[/QUOTE/]
The tree you admire is probably one of the smaller-leafed chinese elms ('Catlin', perhaps, or something similar). However it is difficult to tell because a lack of indication of scale in the photo--we don't know how large the tree is, and consequently, how small the leaves are. Your tree is certainly much smaller, and so the leaves appear larger when the two trees are projected to the same size.
That said, the leaves on your elm are large for two reasons, both having to do with the amount of sunlight that can be absorbed: 1) it is young and has few branches; when it is more mature and has more branches (ramification) it will have more leaves that can be smaller; 2) more important, it appears that you are keeping this tree indoors. Even next to a window it does not receive enough light. Insufficient light = bigger leaves to capture as much light as possible. This tree should be grown outside in full sun. You should list your location so we know what kind of climate you are dealing with. If low temperatures are above freezing, it can, and should, go out now. If it is freezing out, keep it inside, with as much light as possible, and, when the temperature is milder, put it out in full sun, and leave it there year-round (with some winter protection if you live in a northern climate.)
Welcome to bonsai!
