Hi, it's not clear to me where your tree is growing - indoors or out, and that's going to matter a lot as to what happens next. As well, can you please post a picture somewhere (leaving a note here) so we can see the tree, which would be a big help, especially if you can get a good shot or two of a relative close-up of the leaves. You didn't say where you got the tree, but if it was your backyard (or equivalent) you may be growing e.g. a Norway or sugar maple, neither of which are much good for bonsai at all. Thirdly, the best time to work on maples is the winter, when they're dormant (if outdoors where they belong), usually in Feb. before they bud out and before sap flows. Early and mid summer are bad times, so what you might have to do if the pot's too small is get a size larger pot and 'slip pot' - get the whole thing out of its present pot in as much of one piece as possible, disturbing roots as little as possible, and just slip it into the larger one, backfilling with a gritty mix where needed. That would be temporary, but at least deal with the scrunch.

Ravenh that is positively decadent, even by the standards of some of my wealthiest clients. I've seen 100 year old trees that might be worth it if you think of the trees as a living sculpture but I've never seen a 50 year old that was so extraordinarily beautiful to be worth that investment. In the neighborhoods of Greenwich, CT and parts of Westchester, NY (my main work domain) rich folks often purchase 10-20 year old trees from distant commercial orchards. I was called onto an estate owned by a leading fashion-designer- clothing manufacturer where a 50 tree orchard like this had been installed at about 3 grand a tree and after 3 years the trees were completely stunted. The high end nursery responsible for the installation failed to solve the problem even though it was quite obvious when I poked around. The holes had been dug by the same tree spade that dug up the trees so they were the same size as the root ball. The soil was a silt that compacted from pressure from the tree spade and roots could not cross the glazed walls of the planting holes. I proscribed breaking up the soil with shovels from the edge to a few feet beyond the original root ball and didn't hear back from the contractor who subcontracted me for the consultation. A few years later a friend on mine got the contract for the property and subcontracted me to tend the apples and they were in great shape, having completely recovered. I'm taking full credit, of course, although none of the trees were left untreated as a control. In this business when things go well you better take credit because when they don't you will certainly be blamed.

Personally I think a twin is fine. Most of us probably grew up on a twin, she will live on a twin if she goes to college as someone pointed out. I think you have to add to that equation- what type of person is your daughter? Do you think she'll be a reader and like having a little bean bag chair in her own private room to read and do other things that she likes? With friends? Does she have a lot of siblings and this room is her refuge? Or not? Depending on circumstances would lead to two different choices. Also - will this be the room that carries her through her teenage years? Teenagers seem to want to den in their bedroom caves. More room less bed might be better. If she'll be trading up to a bigger room in the house or you are pretty sure you'll be moving before then, not so much an issue. A 10 year old may have preferences if all her choices are laid out and the ins and outs of it all explained - smaller bed, gets to keep dressers, get a bean bag, or a desk or a...whatever or does she prefer the bed and the way things are? You might walk her around a furniture store and let her try on a twin bed. I did think a trundle bed was very cool when I was small. Last - I have friends that have opted for the beds on stilts that have ladders to get more room. Many college kids do this as well, I have even seen home built ones at college that were built at half height, just heigh enough to fit a dresser under. At 10 she's old enough for that to be a safer bet depending on what type of sleeper she is.

Will the girls be sharing for the rest of the time that you live in this home? If so, I would recommend planning for matching twin beds or bunkbeds now, so you can be sure you can match when it's time for little sis to have a big girl bed too.
