Description

The apple is a classic in the home garden and can bear fruit for decades with good care. Old varieties such as 'Boskoop' or 'Goldparmäne' taste more aromatic than any supermarket apple and are often more resistant to scab. Pay attention to having a second variety nearby, because apples need a pollinator.

Care instructions

Plant the tree in late autumn (October week 42) or early spring in loose, deep soil. Prune the interior annually in winter (February week 7) to allow air and sun to reach the fruit. Mulch the root area and water young trees thoroughly in dry summers.
