What are hazelnut tree diseases?
Hi My Hazelnut Tree (5 years old) has within a week suddenly developed dry, curled up leaves. Approximately 90% of the leaves on the tree tree have been effected. I have pruned these branches, but wonder what I can do to treated the rest of the tree and also what has caused this to happen. Look forward to all your answers. Catherine
There are several different species of Hazelnut trees. All of them are in the genus Corylus, which is in the Birch Family, Betulaceae. Some of the species include: Corylus americana Walter- American Hazelnut Corylus avellana L.- Common filbert Corylus colurna L. var. chinensis (Franchet) Burkill- Chinese Hazelnut Corylus cornuta Marshall var. californica (A. DC.) Sharp- California Hazelnut Corylus maxima Mill.- Giant Filbert
hazelnut pruning Cut all but 4 to 5 trunks, and cut all other "watersuckers" that grow each year, and do nothing else. This is proven for best yields. This is for common filibert (Corylus avelana), for Turkish hazelnut (Corylus colurna) leave just one trunk, anyway it grows usually as big tree, so pruning is not necessary.
