Hi Felicia,
Your juniper really belongs outside. *Unfortunately, by the time the foliage begins to fall, these trees are usually dead. *You can scratch the bark with a fingernail at the soil line and see if there is any sign of life (green color).
Most of the trees sold as "mallsai" or commercial bonsai weren't built to last. *They are often underpotted and grown in greenhouse conditions for a few years, then they are shipped around the country and often wind up in the hands of retailers and owners who have no idea how to care for them.
The end result is often a stressed out plant that is overwatered or underwatered and cultivated in less than ideal conditions on top of someone's TV set or near a baseboard heater, or in the living room in the dark.
The result - dead bonsai

Please check out the article called BEWARE THE MALLSAI in
TreeBay Bonsai Tools & Supplies and don't be hard on yourself. *Most people make this mistake the first time.

Matt
