Growing hazelnuts can be a rewarding endeavor, especially for those in New York, where the climate can support their cultivation. Hazel trees (Corylus avellana) are known for their delicious nuts, which are popular in various culinary applications. This article will guide you through the process of growing hazelnuts in New York, covering everything from site selection to harvesting.
Before you begin planting, it’s essential to select the right variety of hazelnut for your region. In New York, the most commonly recommended varieties include:
American Hazelnut (Corylus americana): This native species is well-adapted to the northeastern United States and can tolerate colder temperatures. It produces smaller nuts but is hardy and disease-resistant.
European Hazelnut (Corylus avellana): This variety is often grown for commercial production due to its larger nuts and higher yield. However, it may require more care and protection from cold temperatures.
Hybrid Varieties: Crosses between American and European hazelnuts can offer the best of both worlds—disease resistance along with high nut quality.
Choosing a variety that suits your specific local conditions will increase your chances of a successful harvest.
Hazelnuts thrive best in well-drained soils that are rich in organic matter. Here are some factors to consider when selecting a site for your hazelnut trees:
pH Level: Hazelnuts prefer slightly acidic soil with a pH of 6.0 to 7.0. You can test your soil using a home testing kit and amend it if necessary.
Drainage: Ensure that the site has good drainage; waterlogged soil can lead to root rot. Raised beds or mounds can improve drainage in areas with heavy clay soils.
Hazelnuts require full sun for optimal growth. Aim for at least 6-8 hours of direct sunlight daily. Select a location away from large trees or structures that may cast shadows.
Hazelnut trees need room to grow and spread out. Plant them at least 15-20 feet apart to ensure adequate airflow and reduce competition for nutrients.
Once you’ve selected the right variety and site, it’s time to plant your hazelnuts.
The best time to plant hazelnuts in New York is in spring, after the last frost date, or in fall before the ground freezes, typically between late April and early June or late September through October.
Digging Holes: Dig holes that are about twice the width of the root ball and as deep as necessary to accommodate the roots without bending them.
Soil Preparation: Mix in compost or well-rotted manure into the backfill soil to improve fertility.
Positioning the Tree: Place the tree in the hole so that the root collar (the area where roots meet the stem) is level with or slightly above ground level.
Backfilling: Fill in around the roots with soil, ensuring there are no air pockets by gently tamping down as you fill.
Watering: Water thoroughly after planting to help settle the soil around the roots.
Apply a layer of mulch (such as wood chips or straw) around the base of each tree, extending outwards several feet. This helps retain moisture, suppress weeds, and regulate soil temperature.
Proper care is crucial for healthy growth and productivity:
Hazelnuts require consistent moisture, particularly during dry spells in their first few years. Aim to provide about an inch of water per week through rainfall or supplemental irrigation.
In early spring, you can apply a balanced fertilizer (such as 10-10-10) following manufacturer instructions based on your soil test results. Be cautious not to over-fertilize, as this can lead to excessive leaf growth at the expense of nut production.
Pruning is important for encouraging strong structure and increasing yield:
Young Trees: In the first few years, focus on establishing a central leader while removing any competing branches.
Established Trees: After about 3 years, prune in late winter or early spring before bud break. Remove any dead or diseased branches and thin out crowded areas to improve airflow.
Hazelnut trees are primarily wind-pollinated and typically require cross-pollination from different varieties for optimal nut set. Plant at least two different cultivars within proximity (50-100 feet) to ensure successful pollination and higher yields.
Hazelnuts are susceptible to various pests and diseases, but proactive management can help mitigate these risks:
Filbert Worm: This caterpillar feeds on nuts. Regular monitoring and physical removal can help keep numbers down.
Aphids: These small insects can cause stress on trees but can often be managed with insecticidal soap if infestations occur.
Eastern Filbert Blight: A fungal disease that affects European hazelnuts more than American varieties. Choose resistant cultivars if this disease is prevalent in your area.
Powdery Mildew: This fungal infection can be managed through proper spacing for airflow and fungicides if necessary.
Hazelnuts typically mature in late summer to early fall (August through October). Here’s how to know when they’re ready:
After harvesting, dry nuts thoroughly to prevent spoilage before shelling or storing them.
Growing hazelnuts in New York demands attention to detail—from selecting appropriate varieties and suitable sites to implementing proper care techniques. With patience and dedication, you’ll be rewarded with bountiful harvests of delicious nuts that you can enjoy fresh or use in various recipes throughout the year! Whether you’re looking for a new hobby or aiming for small-scale production, hazelnut cultivation could be an excellent choice for your garden or farmstead in New York. Happy planting!
