I was given a small Juniper Bonsai as a gift in October or November 2010. I have kept it in the house (which I recently discovered,they are an outdoor plant), it seemed to be doing fairly well until the middle of December. I noticed that the needles and some tips were becoming brittle and falling off the plant when touched.I do not over or under water it and I mist it quite frequently. I had it in the kitchen which is situated Northwest and does not get very much sun, so I moved it to a room with South facing windows. Can you give me any advice on what I might do?
