Second Season Hazelnut "Jefferson" (Corylus avellana) Seedling Tree

Also known as OSU 703.007

Planting information: Hardy to zone 4. Grows 8-12 feet in height. Site selection is the most important aspect of growing hazel nuts. The soil must allow for proper root depth, a PH of between six and seven, and dry soil. Hazels will not tolerate wet areas. It is also important to note that hazel nuts require cross pollination but should be planted in areas that are shelter from heavy wind. Hazels do well on the edge or forests and partner well with pine trees. Ideal planting requires a hole deeper and broader than the extended root system to be planted, the addition of a handful of of bone meal into the planting soil. Many growers have found that digging and mixing the previous summer is highly effective. For larger plantings it is recommended to till field strips twice the summer prior to a fall planting. Top mulch with woodchips and water once a week at the rate of one gallon per plant per week. 

Fruiting information: large nuts used in orchards throughout the northwest. Plant with Yamhill for ideal pollination. Quickly bares nuts as soon as year 2-3. 

Benefits Jefferson is understood to be immune to Eastern Filbert Blight and is cold hardy. We have also observed the strain producing a large number of purple leaves popular for retail markets.
