I’ve had this tree for about 3 years. When I purchased it it was the desired shape. It started dropping all it’s leaves and had only one long branch which produced leaves. I decided to prune it back this past spring and almost start over from a trunk and branch nubs, at this time I also sized up to the next pot size, adding about an inch of Miracle Grow soil all around. The attached photos are what has grown back since this spring/summer. I live in North Carolina. The tree is in a window that receives sun all day, I rotate it and water it once a week by giving it a shower. I have never repotted or fertilized Any ideas to help my tree branch and grow? I’m having trouble attaching a photo to the post
