We have a whim of nature to thank for 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, get a compact answer here.
The older the corkscrew hazel, the less care it needs
Does the corkscrew hazel have to be watered?
With increasing age, the watering requirement of a corkscrew hazel decreases noticeably. Water a young plant plentifully and regularly for the first two years after planting, without causing waterlogging. In the further course of growth, the natural rain largely covers the water requirement. Only in the case of prolonged drought and in the bucket, please water when the substrate has dried.
How and when do I fertilize the ornamental shrub appropriately?
In the bed, start-up fertilization with compost and horn shavings (€32.93) at the beginning of March gets the corkscrew hazel going. Continue organic nutrient feeding at 2 to 4 week intervals through August. Changing to a potassium-rich fertilizer in August, such as Thomaskali, AZ Vital-Kali or Comfrey manure, is advantageous for winter hardiness. Please do not apply any fertilizer from September so that the wood matures before winter.
When and how should the wood be cut?
March is the best time for a shape and maintenance cut. Thanks to its prunability, 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 diligently 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 hardness develops gradually. A thick layer of leaves on the root disc and a hood made of breathable fleece are enough. In the bucket, these precautions make sense every year, supplemented by a warm wooden base.
tips
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 here. In the warm, sunny climate and nutritious soil, the ancient Romans already cultivated the magical tree.
