I have two apple trees right outside my back door. They are Columnar apple trees, so they grow tall and straight unlike traditional wide apple trees. I moved them from my old house where I'd planted them before I married Jim, which would make them almost 20 years old now and at least 15 feet tall. Goats LOVE apple trees, so last year they took a real beating. So far this year they are looking amazing.
Mine have not yet bloomed – your photo is a lovely preview of what is to come!
