Here is a closer look at the roots I spoke of.

Before anything - get rid of the pebbles. Then before anything else, put the tree outside where it belongs year round except in the very far north (of Canada). I can't tell from your picture how gritty the soil is or not, but if it's growing in 'potting soil' it needs a better mix. I'm sure it can be trimmed now, but would like to see a clearer, more close up pic of the structure first to advise.

As far as the soil goes it isn't regular potting soil but from what I've read it isn't the ideal soil texture either, I plan on getting a better mix soon. As far as the outdoor although I read they prefer full sunlight and ventilation and breeze are very important I also read they are ok with indoors as per this site at least "When kept inside, this particular tree is considered a semi-evergreen but when grown outdoors, it falls into the deciduous category." http://www.bonsaigardener.org/chinese-elm-care-guide.html. Here is a somewhat better picture of the structure. Thanks for the response.

Well, you can try keeping it inside, but don't be surprised if it doesn't last long. People will say anything to get you to buy!

I agree with Moochinka, I see that you live in Florida. I see I have a fellow northern state in 5a. I have luck taking mine in for the cold months. I will be placing it back outside as the weather breaks.

Leave it OUT year round! It needs to go dormant and what passes for 'cold' in Fla. really isn't, but it's better than indoors.
