Corkscrew Hazel Tree: Planting & Pruning Tips

The corkscrew hazel tree, also known as Corylus avellana 'Contorta', is a unique and fascinating plant species that has gained popularity among gardeners and landscapers due to its distinctive, twisted branches. Native to Europe and Western Asia, this deciduous shrub or small tree is a member of the birch family and is known for its striking, contorted shape. In this article, we will delve into the world of corkscrew hazel trees, exploring their planting and pruning requirements, as well as providing tips and tricks for maintaining these incredible plants.

Introduction to Corkscrew Hazel Trees

Corkscrew hazel trees are a popular choice for gardens and landscapes due to their unusual, twisted branches, which provide a unique aesthetic appeal. These trees are relatively small, typically growing to be around 10-15 feet tall, with a spread of around 8-12 feet. They have a slow to medium growth rate, making them a great choice for gardeners who want to add a statement piece to their yard without having to worry about excessive maintenance. Corkscrew hazel trees are also known for their attractive, yellow-green catkins, which appear in late winter and early spring, adding a pop of color to the landscape.

Planting Corkscrew Hazel Trees

When it comes to planting corkscrew hazel trees, it’s essential to choose a location with full sun to partial shade and well-draining soil. These trees prefer slightly acidic to neutral soil pH, ranging from 6.0 to 7.0. They are also relatively drought-tolerant, but consistent moisture will promote healthy growth and development. To plant a corkscrew hazel tree, dig a hole that is twice as wide and just as deep as the tree’s root ball. Add a layer of organic matter, such as compost or well-rotted manure, to the soil to improve its structure and fertility. Gently remove the tree from its container, taking care not to damage the roots, and place it in the hole. Backfill the soil, tamping it down gently to prevent air pockets, and water thoroughly.

Pruning Corkscrew Hazel Trees

Pruning is an essential part of maintaining corkscrew hazel trees, as it helps to promote healthy growth, encourages new branches to form, and maintains the tree’s unique, twisted shape. The best time to prune a corkscrew hazel tree is in late winter or early spring, before new growth begins. Start by removing any dead, diseased, or damaged branches, cutting them off at the base to prevent the spread of disease. Next, prune any branches that are crossing or rubbing against each other, as this can cause damage and create an entry point for disease. Finally, thin out the tree’s branches to maintain its natural, twisted shape and promote healthy growth.

Tips and Tricks for Pruning Corkscrew Hazel Trees

When pruning a corkscrew hazel tree, it’s essential to use the right tools and techniques to avoid damaging the tree. Use sharp, clean pruning shears or loppers to make clean cuts, and avoid tearing the bark or damaging the branches. It’s also important to prune the tree regularly, as this will help to maintain its shape and promote healthy growth. To maintain the tree’s unique, twisted shape, prune the branches in a way that encourages them to grow in a curved or twisted pattern. This can be achieved by removing any straight branches and encouraging the growth of curved or twisted ones.
