ABSTRACT
This chapter provides information on the uses, folk medicine, chemistry, germplasm, distribution, ecology, cultivation, harvesting, yields, energy, and biotic factors of Beaked Filbert. Most filberts offered for sale by nurserymen have been propagated by layering and are on their own roots. Beaked filberts can be propagated from seed which has been stratified for 60 to 90 days at 5°C. Filberts of all varieties should be planted 5 to 7 m or more apart. Since beaked filberts or hazelnuts tend to sucker, the suckers should be removed promptly and the plant trained to a single stem. Suckers should be removed at the point on the trunk or root where they originate; cutting them off at surface of soil only increases the number that grow. Beaked filberts yield well every 2 to 5 years, and give a light crop every year. Most filbert varieties are self-unfruitful, even though staminate and pistillate catkins are on the same tree or bush.
