Hello, I had my Fig Tree Bonsai for about 2+ weeks now that I bought from Home Depot. About a week ago, the leaves have been falling off and it worries me. I have been watering the plant with Tap Water (maybe a reason why?) and I just got rid of the green decorations they had to help the water get through. Daily, I have placed the bonsai by my window when I'm at school, and then when I come home, I place it outside for more light. I'm worrying so much because I don't know what to do or why it's leaves are falling. The card it came with said to Fertilize it every 2 months; will that help? Maybe the pot it's in is too small? Here's some photos of my tree. Thanks for any help or responses!
