This topic is brought to us by my 9 year old. He collected an Eastern Red Cedar last year that grew like a weed (at least he likes it). The other day, he came back with a tiny collected ERC and explained that this would be "decoration" for his larger ERC like he's seen in pics. He didn't have the word for it, but he was referring to Kusomono. I don't plan on complicating this bonsai process with additional details (I'm limping along as is), but need to ask - what on earth is Kusomono? I understand it is supposed to compliment the tree, and perhaps give off an impression of location and/or season, but I'm not understanding the aesthetic. Insights?
