I live at about 2800ft elevation. I planted this tree in early March. It was one of my first trees to leaf out but it took until mid-late April. In a month, it has grown considerably-full of leaves. I'm excited about the growth, but I do miss the light pink flowers! My advice-be patient. I was worried that it took some time to show any sign of life while friends trees had leafed out a month before mine at slightly lower elevations. Now I can't wait for fruit!
