Fertilising a Corylus avellana 'Contorta'
To encourage robust growth and bountiful fruit production in this unique shrub, proper fertilization is essential. It is advisable to apply a balanced, slow-release fertilizer in early spring as the plant breaks dormancy, and again in mid-summer to sustain its needs throughout the growing season. This ensures that nutrients are available during the crucial periods of new leaf growth and fruit development.
Care should be taken to distribute the fertilizer evenly around the base of the plant, avoiding direct contact with the stem and foliage to prevent burn. Gently work the fertilizer into the top layer of soil and water thoroughly to help disperse the nutrients. Adequate fertilization will not only enhance the shrub's distinctive twisted branches but also support the vibrant yellow catkins and subsequent nut production.
