Growing filberts, commonly known as hazelnuts, can be a rewarding endeavor for both new and experienced gardeners. With their rich flavor and numerous health benefits, hazelnuts have become increasingly popular among home growers, particularly in regions like Nebraska where the climate is well-suited for their cultivation. In this article, we will explore the essential steps to successfully grow filberts in Nebraska.
Hazelnuts come from the Corylus genus of deciduous trees and shrubs. There are several species of hazelnuts, but the most commonly cultivated is the European hazelnut (Corylus avellana). Hazelnuts thrive in temperate climates and require a chilling period during winter to produce nuts effectively.
Nebraska’s continental climate offers a suitable environment for growing hazelnuts. The state experiences cold winters, warm summers, and adequate rainfall, making it ideal for nut production. However, it’s important to select cultivars that are specifically suited for your region within Nebraska.
When selecting hazelnut varieties for cultivation in Nebraska, consider the following:
Choose varieties that have resistance to common diseases such as Eastern Filbert Blight (EFB), which can devastate crops if not managed properly. Some recommended disease-resistant cultivars include:
Hazelnuts are typically self-incompatible, meaning you will need at least two different varieties for good pollination and nut set. Planting multiple varieties within close proximity increases the chances of successful cross-pollination.
Choosing the right location for your hazelnut grove is crucial for optimal growth.
Hazelnuts prefer well-drained, loamy soil with a pH level between 6.0 and 7.5. Conduct a soil test before planting to determine nutrient levels and pH balance. If necessary, amend the soil with organic matter or lime to adjust pH.
Select a site that receives full sunlight for at least six hours a day. Adequate sunlight is essential for healthy growth and nut production.
Ensure proper drainage to prevent root rot. If your chosen site has heavy clay soil or poor drainage, consider raised beds or planting on mounds to enhance drainage.
Once you have selected the right variety and prepared your site, it’s time to plant your hazelnut trees.
The best time to plant hazelnuts in Nebraska is during early spring or late fall when the ground is workable but before new growth begins. This timing allows the roots to establish before extreme temperatures set in.
Spacing: Space trees about 10-15 feet apart to allow for adequate air circulation and sunlight penetration.
Digging Holes: Dig holes that are twice as wide and just as deep as the root ball of your sapling.
Planting: Place the tree in the hole, ensuring that the root collar (where roots meet the trunk) is level with or slightly above ground level. Backfill with soil and water thoroughly after planting.
Proper watering and fertilization are key components of successful hazelnut cultivation.
Hazelnuts require consistent moisture, especially during dry spells. Young trees should receive about 1-2 inches of water per week through rainfall or supplemental irrigation. Avoid overwatering as this can lead to root rot.
Fertilization should be based on soil test results. Typically, a balanced fertilizer with equal parts nitrogen (N), phosphorus (P), and potassium (K) can be applied in early spring as new growth begins. It’s essential not to over-fertilize as this can lead to excessive foliage growth at the expense of nut production.
Pruning is vital for maintaining tree health and maximizing nut yield.
Prune hazelnut trees during late winter or early spring when they are still dormant but before new buds emerge.
Remove Dead or Diseased Wood: Start by cutting away any dead or diseased branches.
Shape Development: Focus on developing an open-center structure by removing any inward-growing branches.
Manage Height: Limit growth height by pruning back tall branches; this will make harvesting easier and encourage bushier growth.
Maintaining vigilance against pests and diseases is crucial for a successful hazelnut crop.
Regular monitoring for signs of disease, especially EFB, is essential:
Harvesting requires careful timing and technique:
Hazelnuts typically ripen between late summer and early fall. The nuts are ready for harvest when they turn brown, fall from the tree easily, or when their husks begin separating from the nut shell.
Proper storage ensures that harvested nuts maintain their quality throughout the year.
Store dried nuts in airtight containers in a cool, dark place such as a basement or refrigerator. Properly stored hazelnuts can last up to two years without losing flavor or quality.
Growing filberts in Nebraska can be an enjoyable experience that yields delicious rewards. By carefully selecting appropriate varieties, preparing your site, managing water and nutrients effectively, pruning wisely, and monitoring for pests and diseases, you increase your chances of having a successful harvest each year. With patience and dedication, you can cultivate your own thriving hazelnut grove in Nebraska!
