Corylus avellana

Hazel Bonsai

This deciduous shrub achieves a rare bonsai feat of being cultivated for its display in winter and not the growing season. Its hefty and sizable leaves make it unsightly in summer, though its hanging yellow catkins that arrive at the end of winter make it a handsome plant. From late summer to the early autumn, this winter display Bonsai produces edible nuts. 

Hazel Bonsai Care Tips

Choose an outdoor location that provides full sun but can provide some shade across the summer. 

Hazel Bonsai demands daily watering across the summer. Ensuring the soil is kept moist is paramount. Observe when its nuts are in growth, this is a particularly vital period requiring consistent soil moisture. 

Throughout the growing season, it is paramount to feed this species once every two weeks. 

To prepare for the plant’s natural autumn and winter display, new growths should be trimmed across the growing season. Robust pruning should take place in March once its catkins have come to an end. 

Hazel Bonsai are suitable for wiring excluding broom and literati styles. Consider your styling if cultivating a ‘corkscrew’ Hazel which has a natural twisted curvature. We recommend using wires with a thickness that matches the thickness of the branch: if the wire you choose is too thick you will damage the bark. If it is too thin, it won’t be effective.

Hazel Bonsai need repotting on an annual basis in early spring. 

Trees that are ready for repotting will require root pruning, a suitable new pot and appropriate soil mix.

When repotting, do not cut back the root mass by a large amount, and choose a well-draining soil mix that has a neutral or slightly higher PH value of 5-6 but not over 7. We tend to use a mixture of different speciality bonsai soils on our trees. Every species is different so please contact us for free soil-mix advice or to take advantage of our repotting service.

Bonsai trees aren’t only magnificent additions to an indoor oasis, they are more than capable of standing out in any garden. Many Bonsai species are incredibly hardy and withstand nature’s colder and damper turns with aplomb making them worthwhile outdoor plants. We have an extensive library of care guides for outdoor bonsai trees. It’s not about selecting the perfect bonsai, it’s about selecting the perfect bonsai for you.

Corylus avellana bonsai are best suited for outdoor cultivation, as they need exposure to natural light and seasonal changes to thrive.

Indoor conditions can stress the plant and make it susceptible to pests and diseases.

Corylus avellana is a relatively fast-growing species, with an average annual growth rate of 30 to 60 cm.

Generally, bonsai grow slower than their counterparts in nature, as they are restricted by limited space and resources.
