Hi. My husband bought me a bonsai tree in May of this year. It has been doing well up until recently. Now, a good portion of the tree is dry and a light green, not a dark green like normal. Also parts of the dry part are brown. Also, the roots I believe are showing. Would I need to plant it into a new pot? It spends all of its time inside by a window. Should I plant it outside? Since I live in a desert climate, would it be best to plant it in direct sunlight (where during summer temps are 105 or higer) or some where close to another tree so the huger tree can shade it some of the time. I need serious help. Please help.
