Culture
Uses
The hazelnut, Corylus avellana ‘Red Dragon’, is primarily sought after for its dual-purpose nature as an ornamental shrub and a nut-producing plant. As a popular landscape shrub, it adds year-round interest to gardens, with its rich, burgundy leaves in spring and summer followed by warm autumnal shades.

These nuts are not only deliciously versatile for culinary use, but also attract wildlife, contributing to biodiversity.
Water
Proper hydration is crucial for the health of the Corylus avellana ‘Red Dragon’. While hazelnuts are relatively drought-tolerant once established, consistent watering is important, particularly during the first few years after planting. Watering the shrub deeply once or twice a week, depending on the climate and soil conditions, is recommended. Ensure the soil remains consistently moist but not waterlogged, as waterlogged conditions can lead to root rot.
Sunlight
The hazelnut plant thrives in full sun, requiring at least 6-8 hours of direct sunlight daily. Adequate sunlight exposure promotes healthy growth and nut production, making it essential for cultivating a thriving Red Dragon hazelnut shrub.
Fertilizer
To promote healthy growth and nut production, it is advisable to fertilize hazelnut shrubs annually in early spring. An application of a balanced, slow-release fertilizer is recommended. Spread the fertilizer around the base of the shrub, taking care not to place it too close to the trunk.
Soil
The Corylus avellana ‘Red Dragon’ prefers well-drained, slightly acidic to neutral soil. Optimal soil conditions encourage healthy root development and reduce the risk of waterlogged conditions, which can be detrimental to the plant’s health.
Pruning
Pruning is an essential aspect of hazelnut shrub care. Regular pruning helps maintain the plant’s shape, remove dead or diseased wood, and improve air circulation within the canopy. It is recommended to prune hazelnut shrubs during the dormant season, typically in late winter to early spring, before new growth emerges. This practice is beneficial for the overall health and aesthetic appeal of the Corylus avellana ‘Red Dragon’.
Propagation
Hazelnuts can be propagated through various methods, including seed propagation, hardwood cuttings, and suckers. Seed propagation is a common method, though it can take several years for the shrub to become established and produce nuts. Hardwood cuttings, taken during the dormant season, offer a more expedited approach to propagating the Red Dragon hazelnut. Suckers, which are new shoots emerging from the base of the shrub, can also be carefully dug up and replanted to create new plants.
Container Popularity
The container planting of hazelnut shrubs is a practice gaining popularity among home gardeners and urban landscapes. Container cultivation offers the advantage of mobility, making it feasible for those with limited garden space to enjoy the beauty and benefits of the Corylus avellana ‘Red Dragon’. When grown in containers, adequate drainage and regular watering are essential for the health and vigor of the shrub.
