Contact allergens

The fuzzy hairs on the leaves and catkins may cause mild skin irritation in sensitive individuals.

Airborne allergens

The windborne pollen is a significant allergen for many people during the early spring flowering season.

Edibility

While the nuts are edible, always ensure they are properly harvested and free from mold before consumption.

Overwintering

The plant is fully hardy and requires no special protection during winter. You can prune out dead or crossing branches while the plant is dormant.

In containers

It is generally too large for long term container growth unless you choose a dwarf cultivar and use a very large pot.

Plant spring ephemerals beneath the hazel to take advantage of the light before the leaves fill in.

Buenas compañeras

• Primrose — They thrive in the dappled shade provided by the hazel canopy.
• Bluebell — These spring bulbs bloom before the hazel leaves fully emerge.

Mantenla lejos de

• Walnut — The walnut tree produces chemicals that can inhibit the growth of nearby hazel bushes.

Especies parecidas

• Filbert — It is closely related but features a much longer, more tubular husk around the nut.
