Hello! My daughter bought me a wonderful flowering tree for Mother's day from M&S. But then when it stopped flowering and leaves started growing some branches became dry. Other branches are still well and growing. I wanted to replant it in a larger pot and prune the dry branches but decided to wait and look for an advice. I wonder what i did wrong. Perhaps I overwatered it while it was in the house. Unfortunately M&S didn't provide me with the name of the tree. The first picture shows how happy it was when it started flowering in my house. The rest pictures show how unhappy it became now. I would appreciate any advice if possible. Thank you in advance.
