Can You Take Cuttings from Contorted Hazel?

Yes, it is possible to take cuttings from contorted hazel (Corylus avellana 'Contorta'), though it is generally considered quite challenging.

Understanding Contorted Hazel Propagation

While contorted hazel is widely admired for its unique twisted branches, propagating it can be more complex than with other plants. Commercial nurseries often propagate Corylus avellana 'Contorta' by grafting it onto the rootstock of a straight Corylus avellana. This method ensures the desired contorted form and often yields more consistent results for large-scale production. It's important to note that any long, straight stems that emerge from the base or along the plant should be removed, as these are typically growth from the straight rootstock or a reversion, and will not develop the characteristic contorted shape.

Hardwood Cuttings: A Challenging Option

For home gardeners looking to propagate contorted hazel, taking cuttings is an option, although it presents a higher degree of difficulty.

Key Considerations for Cuttings

• Type of Cutting: The most suitable method involves using hardwood cuttings. These are taken from mature, dormant stems.
• Timing: The optimal time to take hardwood cuttings from contorted hazel is in late November, when the plant has entered its dormant phase.
• Difficulty: Propagating contorted hazel from cuttings is well-known for being difficult. This means the success rate can be low, and it may require patience and multiple attempts.
• Material Selection: When taking cuttings, always select sections that clearly exhibit the contorted, twisted growth characteristic of the plant. Avoid any straight, vigorous shoots, as these are less likely to develop the desired form and might originate from a rootstock if the parent plant was grafted.

Tips for Enhancing Success (Despite the Difficulty)

To improve your chances when attempting to root contorted hazel cuttings, consider these general best practices for hardwood cuttings:

• Sterile Tools: Always use sharp, clean secateurs to make clean cuts, reducing the risk of disease.
• Rooting Hormone: Dipping the base of the cuttings in a suitable rooting hormone can significantly encourage root development.
• Proper Medium: Plant cuttings in a well-draining, sterile potting mix or a mixture of sand and peat.
• Consistent Moisture: Keep the rooting medium consistently moist but not waterlogged.
• Protection: Protect cuttings from extreme weather conditions, such as hard frosts, by placing them in a sheltered location, a cold frame, or an unheated greenhouse.

Comparison of Propagation Methods

Here's a brief comparison of the two primary methods for propagating contorted hazel:

While taking cuttings from contorted hazel is certainly possible, it requires specific timing, careful material selection, and an understanding that success may not be guaranteed due to the inherent difficulty of the plant in rooting from cuttings.
