Thanks to a whim of nature we have the bizarrely shaped corkscrew hazel with its spiral branches. However, it cannot deny its direct descent from the common hazel, as the requirements for proper care show. All important questions about watering, fertilizing, cutting and more will receive a compact answer here.
How do I properly care for a corkscrew hazel?
Corkscrew hazel care includes regular watering for young plants, organic fertilization from March to August, pruning in March and optional winter protection. Remember to avoid waterlogging and stop fertilizing from September onwards.
Does the corkscrew hazel need to be watered?
As a corkscrew hazel gets older, its need for watering decreases noticeably. Water a young plant abundantly and regularly in the first two years after planting without causing waterlogging. As growth continues, natural rain largely covers the water requirements. Only in the event of persistent dryness or in the pot should you always water when the substrate has dried out.
How and when do I fertilize the ornamental shrub appropriately?
In the bed, boosting fertilization with compost and horn shavings at the beginning of March gets the corkscrew hazel going. Continue organic nutrient feeding at 2 to 4 week intervals through August. It is beneficial for winter hardiness to switch to a potassium-concentrated fertilizer in August, such as Thomaskali (€36.00 on Amazon), AZ Vital-Kali or Comfrey Manure. From September onwards, please stop applying fertilizer so that the tree matures before winter.
When and how should the tree be cut?
March is the best date for a shape and maintenance cut. Thanks to its tolerance to cutting, you can cut the corkscrew hazel back to the desired size. As long as 3 to 4 eyes remain on the branch, the ornamental shrub will continue to sprout again. At the same time, thin out all dead branches and remove 2-4 of the oldest branches to make room for new spiral shoots.
Is the corkscrew hazel hardy?
In the first 3-4 years we recommend winter protection in the bed, as the robust frost hardiness gradually develops. A thick layer of leaves on the root disc and a cover made of breathable fleece are enough. In the bucket, these precautions make sense every year, supplemented by a warm wooden base.
Tip
The botanical name of the corkscrew hazel, Corylus avellana, refers to an Italian town at the foot of Mount Vesuvius. The corkscrew hazel thrives particularly well in the area around Avella, as it has ideal conditions and the perfect location. The ancient Romans already grew the magical tree in the warm, sunny climate and nutritious soil.
