How to Grow Common Hazel
Common Hazel
Corylus avellana
shrubCommon Hazel is a deciduous woody shrub native to Europe and western Asia, prized for its edible hazelnuts and ornamental catkins. It grows 12-20 feet tall and wide, with a multi-stemmed growth habit and attractive yellow male catkins in late winter. The plant is hardy, long-lived, and serves multiple purposes including nut production, wildlife habitat, and traditional coppicing.

Establishment
1-2 yearsYoung shrub settles in with leaf emergence and root development; growth may be slow first year
Water regularly during first growing season; mulch to retain moisture and suppress weeds; prune only to remove damaged wood
Vegetative Growth
2-3 yearsShrub develops dense branching structure with heart-shaped leaves; yellow catkins appear in late winter (January-February)
Encourage multi-stemmed form or train to single stem depending on desired shape; thin crossing branches; fertilize with balanced NPK in spring
Flowering & Pollination
4-6 weeks (late winter to early spring)Male catkins elongate and shed pollen; small reddish female flowers appear on branch tips; male catkins are highly ornamental
Ensure adequate plant spacing for air circulation and pollination; plant multiple cultivars for cross-pollination and better nut set; no spraying during flowering
Nut Development
4-5 months (spring through late summer)Developing hazelnuts form within leafy involucres (husks); nuts enlarge and harden through summer; husks dry and begin to crack
Monitor for pests and diseases; maintain consistent watering during dry spells; thin crowded growth to improve air circulation and nut size
Harvest & Dormancy
Harvest September-October; dormancy November-MarchNuts mature fully and drop to ground in autumn; leaves turn yellow and fall; plant enters winter dormancy
Harvest nuts as they drop or shake branches gently over cloth; cure in cool, dry location; clean shells of husks; prune during dormancy if coppicing

Common Pests
-
Monitor with pheromone traps; remove and destroy infested nuts; encourage natural predators; dormant oil spray in late winter
-
Handpick infested shoots; prune affected branches; encourage beneficial parasitic wasps
-
and
Netting or exclusion barriers; harvest nuts promptly; accept some natural predation as part of ecosystem
-
Plant resistant cultivars; prune out infected branches 6-12 inches below visible cankers; burn pruned material; maintain good air circulation; sanitize tools
-
Strong water spray to dislodge; insecticidal soap; encourage natural predators like ladybugs; rarely requires treatment on mature plants
Uses
Edible Hazelnuts & Confectionery
CulinaryHazel nuts are prized worldwide for eating fresh, roasting, or grinding into hazelnut butter and oils. They are key ingredients in chocolate spreads, baked goods, and gourmet cuisine. [source]
Foraged Food Source
CulinaryIn traditional foraging cultures, hazelnuts provided essential nutrition and calories, particularly in autumn and stored through winter. [source]
Coppice & Woodworking
HouseholdHazel has been coppiced for centuries to produce straight, flexible poles for basketry, hurdle-making, traditional fencing, and rustic construction. Hazel poles are highly prized for these crafts. [source]
Divining Rods & Dowsing
CraftHazel branches, particularly Y-shaped forked twigs, have been traditionally used as divining rods to locate water and minerals. This practice persists in folk tradition and alternative practices. [source]
Wildlife Habitat & Food
WildlifeCommon Hazel provides dense shelter and food for numerous bird and mammal species, including grouse, deer, and small rodents. It is a keystone plant for woodland ecology and biodiversity. [source]
Harvest Tips
Hazelnuts mature and drop in fall (September-October in northern zones, August-September in warmer areas). Harvest daily by collecting fallen nuts, or gently shake branches over a tarp. Remove husks and air-dry nuts in a cool, well-ventilated location for 2-3 weeks until shells harden and rattle inside their shells. Store in cool, dry conditions (32-50°F, 50-65% humidity) for long-term storage. Squirrels will also harvest—accept this natural loss as part of ecosystem benefit.
Fun Facts
- 🌱 Hazel has been used for thousands of years—Archaeological evidence shows humans harvested hazelnuts in the Mesolithic period (6000+ years ago), and it is deeply embedded in Celtic mythology and European folk tradition.
- 🌱 Coppiced hazel can live for hundreds of years; a properly managed hazel coppice can be harvested repeatedly from the same root system for 300+ years, making it an extremely sustainable resource.
- 🌱 The catkins are among the first signs of spring in temperate climates, often appearing while snow is still on the ground; they provide early pollen for hungry insects emerging from dormancy.
