I bought my bonsai tree two weeks ago from IKEA. Originally I had it placed on my windowsill to ensure it got plenty of light. However there was a radiator nearby and I was advised by a friend to move it as it will get too hot.
I've now put it in a bathroom which has less light but is a cooler environment.
Since I bought it home it's been shedding leaves regularly. However it seems to shedding more since I moved it to my bathroom - at an alarming rate.
The leaves have also started to turn brown as they drop off. It definitely did not have any dying leaves when I purchased it.
I only water it if the soil is dry when I touch it so I don't think it's been over watered.
I've always wanted a bonsai and now I'm worried I'm ruining it!
Please can you help? Should I move it someonewhere warmer and with more light? I hope it's not beyond saving


I'd really appreciate any help/advice.
