That is pretty cool to get any fruit on such a young tree.
My mother in law bought a cherry tree last year from a garden center and got 1 cherry on it last year. It was probably a few years old already when she bought it. This year there are hundreds of cherries on it so you might get a decent yield next year.
thank you! that's great! yeah, its a good sign... my tree is not even up to my waste yet, and is already fertile, so hopefully it will gain a lot of of height this year, so more fruits can come out of it. Unfortunately we dont have a good climate for growing cherries, I love them too!
