Before getting into the specifics of pruning techniques, it is essential to understand the structure of hazelnut trees. They typically grow as multi-stemmed shrubs or small trees. Knowing their natural form helps in deciding which branches to keep or remove during pruning sessions.
When to Prune Hazelnut Trees
The timing of pruning can significantly affect the results. Generally, the best time to prune hazelnut trees is during late winter or early spring, just before new growth begins. This timing allows for several advantages:
- It minimizes stress on the tree.
- It reduces the risk of sap loss.
- It allows for better visibility of the tree’s structure, making it easier to identify which branches need attention.
However, in regions with milder winters, some growers may choose to do light pruning during the summer months after harvest. This can be beneficial for shaping the tree without stimulating excessive new growth that could be vulnerable to winter damage.
Basic Pruning Techniques
Proper pruning techniques are vital for achieving the desired results. Here are some fundamental methods to consider:
Thinning Cuts
This technique involves removing entire branches at their point of origin. Thinning cuts help to open up the tree’s canopy and can significantly improve light penetration and air circulation.
Heading Cuts
A heading cut shortens a branch by cutting it back to a bud or a lateral branch. This encourages new growth and can help control the size of the tree while promoting bushy growth, which is beneficial for producing more nuts.
Renewal Pruning
This method focuses on removing older branches to encourage new growth. Typically, older branches are less productive than younger ones. By selectively removing older wood, you can stimulate the growth of more fruitful shoots.
| Pruning Technique | Description | Benefits |
|---|---|---|
| Thinning Cuts | Removing branches at their origin | Improves air circulation and light penetration |
| Heading Cuts | Shortening branches to a bud | Encourages new growth and controls size |
