It's a dormant fungicide but it also helps preserve the wood a little bit. When you first put it on, it turns to a bright orange-yellow. In another 24 hours, it will turn into a nice bone white and give it that bleached look. It really has an old, haunting look about it. It's sort of a delicate look, but yet having a violent past.
Any woody plant is eligible to be a bonsai.
Some are a little better than others. Well, that gives it more of a feeling of age. And when we put wire on it the wire holds the position a bit better when it's woody. Right here, I've got a natal plum. That's a podocarpus, it's also called buddhist pine.
