Nursery - Tree Quality
With each plantation, the fruit grower undertakes a considerable investment for the next 12 to 20 years. Only fruit trees of optimal quality ensure a swift return on investment.
Since the beginning of the tree production, Gräb nursery claims to cultivate only well- feathered and rooted plant material. Well rooted starter material, that we receive from selected rootstock nurseries, is only one component for our quality trees.
After grafting, we remove herbaceous branches on the trunk several times at an early stage to prevent undesired pruning wounds.
In this way, we are able to offer our customers appropriate trees with different stem heights. Furthermore, customized solutions can be elaborated in terms of variety-rootstock combinations.
