Growing hazelnuts can be a rewarding endeavor for both amateur and professional growers. These tree nuts are not only delicious but also packed with nutrients, making them a popular choice among consumers. If you are considering cultivating hazelnuts in Illinois, this guide will provide you with all the essential information on how to grow this valuable crop.
Hazelnuts, scientifically known as Corylus avellana, are deciduous trees or large shrubs that produce edible nuts encased in a hard shell. They thrive in well-drained soils and prefer temperate climates. Hazelnut trees can grow up to 20 feet tall and require cross-pollination for optimal nut production.
When selecting a variety of hazelnut for planting in Illinois, consider factors such as climate adaptability, disease resistance, and yield. Some popular varieties suitable for Illinois include:
In addition to traditional varieties, hybrid hazelnuts have been developed to combine traits from different species, providing increased hardiness and disease resistance. Research and select hybrids that have shown successful growth in the Midwest.
Hazelnuts prefer well-drained loamy soils with a pH between 6.0 and 7.0. Heavy clay soils can retain too much moisture and lead to root rot. Conduct a soil test before planting to determine pH levels and nutrient content.
Hazelnut trees thrive in full sun but can tolerate partial shade. Ensure your chosen site receives at least six hours of direct sunlight per day for optimal growth and nut production.
Planting your hazelnuts in an area protected from strong winds will help prevent damage to the trees and ensure better pollination. Consider planting windbreaks or other forms of shelter if necessary.
The best time to plant hazelnut trees is during the early spring or fall when the soil temperature is favorable for root establishment.
After planting, keep the soil consistently moist for the first year while the roots establish themselves. Use mulch around the base of each tree to retain moisture and suppress weeds.
Hazelnut trees generally require minimal fertilization if planted in healthy soils; however, you might need to apply nitrogen-rich fertilizers during the growing season if growth appears stunted.
Pruning is essential for maintaining tree health and maximizing yields:
Hazelnuts can be susceptible to certain pests like aphids, caterpillars, and beetles, as well as diseases such as eastern filbert blight (EFB). Integrate organic pest management techniques:
Since hazelnuts require cross-pollination for optimal nut production, it’s crucial to plant multiple varieties within proximity (ideally within 100 feet) of each other. Choose complementary varieties that bloom concurrently to ensure high pollination rates.
Hazelnuts typically mature in late summer to early fall—around September or October—depending on the variety. Nuts are ready for harvest when their husks begin to turn brown but before they drop from the tree.
After harvesting, remove any debris from nuts and dry them thoroughly before storage.
To preserve freshness, store harvested hazelnuts in a cool, dry place away from direct sunlight. Properly dried nuts can last up to two years when stored in airtight containers in a refrigerator or freezer.
Growing hazelnuts in Illinois can be a fruitful venture both literally and figuratively! With proper site selection, planting techniques, maintenance practices, and pest management strategies, you can enjoy abundant harvests of this nutritious tree nut for years to come. Whether you’re looking to start a small orchard or simply plant a few trees in your backyard, following these guidelines will help you succeed in your hazelnut-growing endeavors.
