Whether you're a seasoned gardener or a novice enthusiast, here's a comprehensive guide to help you embark on your hazelnut-growing journey.
Understanding Hazelnuts
Hazelnuts, also called filberts or cobnuts, are the nuts produced by the hazel tree (genus Corylus). These trees are hardy and adaptable, thriving in temperate climates across the globe. Hazelnuts are rich in protein, fiber, healthy fats, vitamins, and minerals, making them a valuable addition to any diet.
Selecting Hazelnut Varieties
Before starting your hazelnut cultivation project, it's crucial to choose the right variety suited to your climate and space. Some popular hazelnut cultivars include:
Contorted Filbert (Corylus avellana 'Contorta'): Known for its twisted and contorted branches, this variety adds ornamental value to your garden while producing delicious nuts.
Barcelona: A popular commercial variety, Barcelona hazelnuts are known for their large size and excellent flavor.
Jefferson: This variety is prized for its high yields and disease resistance, making it an excellent choice for home growers.
Tonda di Giffoni: Originating from Italy, this cultivar produces medium-sized nuts with exceptional flavor.
Site Selection and Soil Preparation
Hazelnuts thrive in well-drained soil with good sunlight exposure. When selecting a site for planting, consider the following factors:
- Sunlight: Choose a location that receives at least six hours of sunlight daily.
- Soil Quality: Hazelnuts prefer loamy, well-drained soil with a pH between 6.0 and 7.5.
- Space: Ensure that the selected area provides ample room for the hazelnut trees to mature, as they can reach heights of 10 to 20 feet.
Before planting, prepare the soil by incorporating organic matter such as compost or aged manure to improve fertility and drainage.
Planting Hazelnut Trees
Hazelnut trees are typically propagated through bare-root or container-grown seedlings. Follow these steps for successful planting:
- Timing: Plant hazelnut trees in late winter or early spring while they are still dormant.
- Digging Holes: Dig holes that are twice as wide and deep as the root system of the seedling.
- Spacing: Plant multiple hazelnut trees approximately 15 to 20 feet apart to allow for proper air circulation and growth.
- Planting Depth: Position the seedling in the center of the hole and backfill with soil, ensuring that the graft union (if present) remains above the soil level.
- Watering: Thoroughly water the newly planted seedlings and mulch around the base to retain moisture and suppress weed growth.
Care and Maintenance
To ensure healthy growth and abundant harvests, provide ongoing care and maintenance to your hazelnut trees:
- Watering: Hazelnut trees require regular watering, especially during dry periods. Keep the soil consistently moist but not waterlogged.
- Fertilization: Apply a balanced fertilizer in early spring before new growth emerges to provide essential nutrients.
- Pruning: Prune hazelnut trees during the dormant season to remove dead or diseased branches and shape the canopy for optimal sunlight penetration and air circulation.
- Pest and Disease Control: Monitor your hazelnut trees for signs of pests such as aphids, mites, and filbertworms, as well as diseases like Eastern filbert blight. Implement appropriate control measures as needed, including the use of organic pesticides and cultural practices.
Harvesting Hazelnuts
Hazelnut trees typically begin bearing nuts within 2 to 3 years after planting, with full production reached by 5 to 7 years. Harvesting usually occurs in late summer or early fall when the nuts are mature and begin to drop from the trees. To harvest hazelnuts:
- Timing: Monitor the trees regularly and collect the nuts as soon as they start falling to the ground.
- Gathering: Gather the nuts by hand or lay out tarps beneath the trees to catch the falling nuts.
- Drying: After harvesting, spread the nuts in a single layer and allow them to air dry for several weeks until the husks begin to crack open.
- Storage: Store the dried hazelnuts in a cool, dry place in airtight containers to maintain freshness and prevent spoilage.
