Depends which root stock it is grafted onto

if its grafted onto M26 rootstock it should only make about 6ft, M27 rootstock should make 12ft, any other rootstock and it will reach about 25ft.

Sounds like I need M26 thank you Steve

How wide does it spread? and what conditions does it like? I really love these trees, especially when the blossom difts along on the breeze
