How to Grow Hazelnuts (nut but often considered a fruit) in Utah

Growing hazelnuts in Utah can be both a rewarding and productive endeavor. These delightful nuts are not only delicious but also packed with nutrients and can be used in a variety of culinary applications. Despite their popularity, many people may not realize that hazelnuts are often categorized as a fruit due to their botanical classification. This article will provide comprehensive guidance on how to successfully grow hazelnuts in Utah, covering everything from selecting the right varieties to harvesting techniques.

Understanding Hazelnuts

Hazelnuts, known scientifically as Corylus avellana, are deciduous shrubs or small trees that belong to the birch family. They thrive in temperate climates and are particularly well-suited for regions with cold winters and moderate summers. While many people think of hazelnuts as nuts, they are technically categorized as fruits because they possess a hard shell enclosing a kernel.

In Utah, where climate varies significantly between regions, understanding local conditions is critical for successful hazelnut cultivation.

Choosing the Right Hazelnut Variety

When selecting hazelnut varieties for planting in Utah, it is essential to look for cultivars that are well-adapted to the regional climate. Here are some recommended varieties:

  1. Barcelona: This is one of the most popular commercial cultivars and is known for its large, high-quality nuts. It is also resistant to Eastern Filbert Blight (EFB), a common disease affecting hazelnuts.

  2. Jefferson: Another EFB-resistant option, Jefferson produces medium to large-sized nuts with excellent flavor. It is suitable for areas with colder winters.

  3. Rush: This variety has lower susceptibility to EFB and produces flavorful nuts that ripen later in the season, making it an excellent choice for staggered harvests.

  4. Yamhill: Known for its adaptability, this cultivar flourishes under various conditions and yields high-quality nuts.

In addition to these, local agricultural extensions may have additional recommendations based on specific regional conditions within Utah.

Site Selection

Choosing the right site is crucial when growing hazelnuts. Here are some factors to consider:

Soil Requirements

Hazelnuts prefer well-drained soils rich in organic matter. The ideal pH level ranges from 6.0 to 7.5. Conducting a soil test before planting can help you understand your soil’s nutrient content and pH level. If necessary, amend the soil by adding organic compost or other amendments to promote healthy growth.

Sunlight Exposure

Hazelnut trees thrive best in full sunlight, requiring at least six hours of direct sunlight each day. Ensure that the selected site is free from shade cast by larger trees or buildings.

Space Considerations

Hazelnut plants can grow anywhere from 10 to 20 feet tall and wide depending on the variety. When planting multiple trees, space them about 15 to 20 feet apart to allow for adequate air circulation and sunlight penetration.

Planting Hazelnuts

Once you’ve prepared your site and selected your variety, it’s time to plant your hazelnuts.

Timing

The best time for planting hazelnut trees in Utah is during early spring after the last frost or in late fall before winter sets in. This allows the young plants time to establish roots before the challenging summer heat or winter cold arrives.

Planting Method

  1. Digging Holes: Prepare holes that are about twice the size of the root ball of the sapling.
  2. Placing the Tree: Gently place the tree into the hole, ensuring that it sits at the same depth as it was grown in its container.
  3. Backfilling and Watering: Backfill with soil and lightly pack it down around the base of the tree. Water thoroughly after planting.
  4. Mulching: Apply a layer of organic mulch around the base of each tree to help retain moisture and suppress weeds.

Care and Maintenance

Proper care will ensure healthy growth and a fruitful harvest from your hazelnut trees.

Watering

Hazelnuts require consistent moisture, especially during their first few years of growth. Water deeply once a week during dry spells or drought conditions but avoid waterlogging, which can harm roots.

Fertilization

Applying a balanced fertilizer in early spring will provide essential nutrients for healthy growth. Be cautious not to over-fertilize; this can cause excessive leaf growth at the expense of nut production.

Pruning

Pruning is vital for maintaining tree health and encouraging nut production. Remove any dead or diseased branches annually in late winter. Additionally, consider thinning out crowded branches each year to improve air circulation within the canopy.

Pest Management

Like any crop, hazelnuts are susceptible to various pests and diseases:

Regularly inspect your plants for signs of pests or diseases and take action promptly if problems arise.

Pollination

Hazelnuts are typically wind-pollinated; therefore, planting multiple varieties will enhance cross-pollination and increase nut yield. Ideally, you should plant at least two different varieties within proximity (about 50 feet) of each other for effective pollination.

Harvesting Hazelnuts

The timing of harvesting is critical for obtaining quality nuts:

When to Harvest

Hazelnuts typically mature late summer through early fall (August to October). You’ll know they’re ready when the husk turns brown and starts separating from the nut itself.

Harvesting Method

To harvest:
1. Gently shake branches or use a tarpaulin beneath them to catch falling nuts.
2. Remove any husk remains from the nuts.
3. Dry harvested nuts thoroughly in a cool, shaded area before storing them in an airtight container.

Storing Hazelnuts

To maintain quality after harvesting:
– Store unshelled nuts in a cool, dry place.
– Shelled nuts should be kept refrigerated or frozen if not used within several months, as they can spoil quickly due to their high-fat content.

Conclusion

Growing hazelnuts in Utah offers gardeners an opportunity to cultivate delicious fruits while enjoying sustainable farming practices. By selecting suitable varieties and providing proper care throughout the growing season, you can enjoy bountiful harvests year after year. Whether you plan on using them in baking or simply snacking on them raw, hazelnuts are an excellent addition to your garden that brings both flavor and nutrition into your life!
