I received an 8 year old bonsai as a gift and it arrived in the mail plush and beautiful - every single branch had lush leaves. After 2 months every single leaf is gone, and I've moved it from my office to my house to get more natural light.
Right now its at a NORTH facing window, so doesn't get much sun. Should I invest in a grow light? I water every other day or so.
Do I need fertilizer or is it winter woes??
