New to Bonsai trees

Hi, I'm new to Bonsai Club and keeping bonsai trees:
I live in zone 5A (northern Illinois) and purchased a Japanese Juniper (prostrate style, not sure which type) this past 10-2009. The tag on the tree stated it was 85 years old (unknown if true). It is 19" long, 9" wide, and about 8" high from the base of the trunk. Thus far, because of the colder temps (winter) the plant has been indoors only. I provide light thru one of the windows and try to keep the soil moist. I need advice on it's care and possible transfer to the outside (this Spring?). I can e-mail high res images if requested.
I would appreciate any help you can offer.
Thanks, Kamikaze

Hello Kamikazi. All Junipers are kept as outdoor trees. Some overwinter their Junipers in a cold greenhouse or well lit shed/ garage. As yours is used to indoor temps, you could damage it by placing it outside. I would recomend a cold room in your house until Spring. Judging by your description, its doubtful that its so old, Photos are always a good idea, for advice or direction.

Thanks for the reply. Being new to this site, I don't know if images can be loaded on to this site. If so, please let me know how.

Hi and welcome the the IBC. Best thing is to do for learning how to upload photos is to go into Jim Lewis's tutorial in the Testing forum. Click HERE and you should get to it - if not it's the first board on the main forum index.

Just follow the steps Jim outlines.

Hope this helps.
