Corkscrew Hazel Problems UK

The Corkscrew Hazel, also known as Corylus avellana ‘Contorta’, is cherished for its unique “Triffid”-like winter appearance, its beautiful long catkins produced during January and February, and the attraction it holds for birds like the Long-Tailed Tits. However, some garden enthusiasts have found that managing its growth, particularly in smaller gardens, can be challenging.

Problem: Rapid Growth and Overcrowding in Small Gardens The primary issue some UK gardeners face with Corkscrew Hazel is its overwhelming size during the summer months, especially when planted in smaller gardens. This rapid growth can make the tree appear dark and menacing, taking over garden borders and overshadowing other plants.

Potential Solutions:

1. Pruning: One of the recommended strategies is pruning the tree. While some might find pruning akin to “herding cats,” it’s essential to ensure the tree doesn’t become too dominant. Gardeners should be careful not to prune below the graft and it’s advised to prune right after the catkins finish and before the leaves appear.
2. Seek Professional Help: If you’re unsure about pruning or managing the growth of the Corkscrew Hazel yourself, consider hiring a tree surgeon or a professional gardener to help.
3. Growing in Pots: Another alternative solution to controlling its size is by growing the tree in a pot. It has been reported to slow its growth. However, if considering this option:
   • Advantages: Easier pruning, movability, and it keeps the tree small.
   • Disadvantages: Regular watering is necessary as the soil dries out quickly. There’s also the risk of the pot being blown over in strong winds and more frequent branch die-back due to inconsistent watering.
   If grown in a pot, ensure the use of substantial shrub/tree compost and a pot size that can accommodate its growth. Regular feeding, especially during summer, is essential.
4. Transplanting: If a Corkscrew Hazel has been in a pot and has outgrown it, it’s possible to transplant it to the garden. Some have found success with transplanting and then keeping the tree’s size in check through regular pruning.
5. Replace with Another Plant: If managing the Corkscrew Hazel becomes too challenging, consider replacing it with another plant more suitable for your garden’s size and requirements.

Conclusion: Corkscrew Hazel is undeniably a beautiful and unique tree to have in one’s garden. However, with beauty comes responsibility. Regular care, pruning, and understanding its growth habits can ensure that it remains an asset rather than becoming a cumbersome presence in your garden.
