A selection of Malus x zumi.
The Netherlands .
Mid-time. The flowering is overwelming and regular on the branches of one to four years old. Professor Sprenger is a very good pollinator for Cox, Delcorf, Elstar and Gala.
Much anther dust of high quality.
It takes quite a long time for the apples to fall of the tree. Not suitable for consumption.
The apples of Professor Sprenger are quite small with an yellow - red-orange blush.
Not sensitive for scab and mildew. We advise to use at least three different varieties of ornamental apple trees in order to have enough anther dust available during the flowering period of the relevant apple variety.
