Understanding Hazelnut Tree Growth
Hazelnut trees (Corylus avellana) are deciduous shrubs that can grow up to 20 feet tall. They typically start producing nuts within three to five years after planting. Understanding their growth habits is crucial for effective pruning. The trees develop a bushy shape with multiple stems, which can lead to overcrowding if not managed properly. Regular pruning helps maintain an open center, allowing light and air to penetrate.
One of the significant factors affecting hazelnut yield is the tree’s age. Young trees require different pruning techniques compared to mature ones. For instance, young hazelnuts should be pruned to establish a strong framework. This involves selecting the best stems and removing weaker ones to encourage robust growth.
Types of Pruning Techniques
There are several pruning techniques that farmers can employ when managing their hazelnut orchards. Each technique serves different purposes and can be tailored according to the specific needs of the trees.
1. Thinning
This technique involves removing entire branches back to their point of origin. Thinning opens up the canopy, allowing better airflow and sunlight access. This method helps reduce disease pressure and promotes larger nut production.
2. Heading Back
Heading back involves cutting back a portion of a branch to a bud or lateral branch. This encourages bushier growth and can help manage the height of the trees, making them more accessible for harvesting.
3. Renewal Pruning
As hazelnut trees age, renewal pruning becomes essential. This technique focuses on removing older branches that have decreased productivity. By replacing them with younger shoots, farmers can maintain consistent nut production levels.
