Growing Twisted Hazelnut Trees: A Guide to Cultivating Unique and Ornamental Landscaping Features
Twisted hazelnut trees, with their contorted branches and intriguing shapes, are not only fascinating to look at but also valuable additions to any landscape. Whether you're seeking to create a focal point in your garden or add visual interest to your outdoor space, growing twisted hazelnut trees can be a rewarding endeavor. Here's a comprehensive guide to planting and nurturing these unique trees:
Selecting the Right Variety:
Before planting twisted hazelnut trees, it's essential to select the right variety that exhibits the characteristic contorted growth habit. Some popular cultivars include Corylus avellana 'Contorta' (also known as Harry Lauder's walking stick) and Corylus avellana 'Red Majestic.' Research different varieties to find one that suits your climate, space, and aesthetic preferences.
Choosing the Planting Location:
Twisted hazelnut trees thrive in full sunlight to partial shade, so choose a spot in your garden that receives at least 6 hours of direct sunlight per day. Ensure the location has well-drained soil with good air circulation to prevent waterlogging and reduce the risk of fungal diseases. Consider the ultimate size of the tree and its proximity to other plants or structures.
Preparing the Soil:
Before planting, prepare the soil by loosening it to a depth of about 12 inches. Remove any weeds, rocks, or debris, and incorporate organic matter such as compost or aged manure to improve soil fertility and structure. Twisted hazelnut trees prefer slightly acidic to neutral soil with a pH of 6.0-7.0.
Planting Twisted Hazelnut Trees:
Plant twisted hazelnut trees in the spring or fall, avoiding periods of extreme heat or cold. Dig a hole that is slightly wider and no deeper than the root ball of the tree. Place the tree in the center of the hole, making sure the top of the root ball is level with the surrounding soil. Backfill with soil, gently firming it down around the roots, and water thoroughly to settle the soil.
Watering and Care:
Keep the soil consistently moist but not waterlogged, especially during the first growing season. Water deeply once or twice a week, depending on weather conditions and soil moisture levels. Mulch around the base of the tree to help retain moisture, suppress weeds, and protect the roots from temperature extremes.
Fertilizing:
Twisted hazelnut trees benefit from regular feeding to support healthy growth and development. Apply a balanced, slow-release fertilizer formulated for trees and shrubs in early spring, before new growth begins. Follow the manufacturer's instructions for application rates and frequency, and avoid over-fertilizing, as this can lead to excessive foliage growth at the expense of the twisted branches.
Pruning and Maintenance:
Prune twisted hazelnut trees regularly to maintain their unique shape and remove any dead, damaged, or crossing branches. Prune in late winter or early spring before new growth emerges, using clean, sharp tools to make precise cuts. Remove any suckers or water sprouts that emerge from the base of the tree.
Protecting from Pests and Diseases:
Monitor twisted hazelnut trees regularly for signs of pests such as aphids, scale insects, or caterpillars, and treat as needed with organic pest control methods. Watch for symptoms of common hazelnut diseases such as Eastern filbert blight or powdery mildew, and treat promptly with fungicides labeled for ornamental trees.
By following these tips for planting and care, you can cultivate healthy and visually striking twisted hazelnut trees that enhance the beauty and intrigue of your garden. With their contorted branches and unique shapes, twisted hazelnut trees are sure to captivate the imagination and bring charm to your outdoor space for years to come.
