Growing hazelnuts can be a rewarding endeavor for both amateur and seasoned gardeners in Missouri. With the right climate, soil, and care, you can cultivate this nutritious nut that is not only delicious but also has various culinary applications and health benefits. This article outlines everything you need to know about growing hazelnuts in Missouri.
Before starting your hazelnut garden, it’s crucial to understand the different varieties of hazelnuts suitable for Missouri’s climate. The most common types are:
European Hazelnut (Corylus avellana): Known for its rich flavor, the European hazelnut thrives in well-drained soil and requires a chill period for proper nut development.
American Hazelnut (Corylus americana): Native to North America, this variety is more resistant to diseases and pests but may produce smaller nuts compared to the European variety.
Hybrid Varieties: These varieties are bred to combine the best features of both European and American hazelnuts, offering disease resistance along with good nut quality.
When choosing a hazelnut variety, consider factors such as your specific location within Missouri, potential pest pressures, and the intended use of the nuts.
Selecting an appropriate site is crucial for successful hazelnut cultivation. Here are key factors to consider:
Hazelnuts prefer well-drained soils with a pH between 6.0 and 7.5. Sandy loam or clay loam soils work best. Before planting, conduct a soil test to assess nutrient levels and pH balance. If necessary, amend the soil with lime to raise pH or sulfur to lower it.
Hazelnut trees thrive in full sun, requiring at least six hours of direct sunlight each day. Choose a location that receives adequate sunlight while being sheltered from strong winds, which can damage young plants.
Proper drainage is essential; waterlogged roots can lead to diseases such as root rot. If your soil tends to retain water, consider building raised beds or planting on slopes.
The best time to plant hazelnuts in Missouri is during the spring (April through mid-May) after the last frost date. This timing allows the young plants to establish roots before facing the summer heat.
Spacing: Plant hazelnut trees approximately 15-20 feet apart; this allows ample room for growth and air circulation.
Planting Depth: Dig a hole twice as wide and just as deep as the root ball of the sapling. Place the tree in the hole at the same depth it was growing in the nursery.
Backfilling: Backfill with a mix of native soil and organic compost. Avoid compacting the soil too tightly around the roots.
Watering: Water thoroughly after planting, ensuring that moisture reaches deep into the root zone.
Proper watering is essential during the first few years of growth. Young hazelnut trees need consistent moisture but should not be overwatered. Aim for about an inch of water per week during dry spells. Once established, hazelnuts are relatively drought-tolerant.
Fertilize your hazelnut trees annually in early spring using a balanced fertilizer high in nitrogen (such as 10-10-10). Follow package instructions regarding application rates based on tree age and size.
Pruning is vital for maintaining plant health and productivity:
Timing: Prune during late winter or early spring before new growth begins.
Techniques: Remove any dead or diseased branches, as well as those that cross or rub against each other. Aim for an open center structure that allows light penetration into the canopy.
Hazelnuts can be susceptible to various pests and diseases:
Filbert Worms: The larvae feed on developing nuts, leading to reduced yields.
Leaf Blisters: This fungal disease causes leaves to develop blisters, impacting photosynthesis.
To manage pests effectively:
Maintaining good air circulation around plants helps prevent fungal diseases. Additionally, ensure proper watering techniques to avoid waterlogged conditions that promote root rot and other issues.
Hazelnuts typically mature between late summer and early fall (August through October). They are ready for harvest when their hulls begin turning brown and start to separate from the nut.
Hand Harvesting: Gently shake branches or use a stick to knock nuts from trees onto tarps laid below.
Mechanical Harvesting: In larger orchards, mechanical shakers may be employed for quicker collection.
Post-harvest, remove any debris from your nuts by shelling them immediately or drying them thoroughly if storing unshelled nuts.
Proper storage is key to preserving flavor and quality:
Growing hazelnuts in Missouri offers numerous benefits, from providing nutritious food sources to enhancing local biodiversity. With careful planning, site selection, and maintenance practices outlined above, you can create a productive hazelnut grove that thrives in Missouri’s unique climate. Whether you’re looking to harvest for personal use or add value through sales at local markets, investing time in learning about this fascinating tree will undoubtedly pay off in delicious ways!
