Fertilising a Corylus avellana 'Rode Zellernoot'
To support vigorous growth and optimal nut production, Corylus avellana 'Rode Zellernoot' should be fertilized annually. The ideal time to fertilize this shrub is in late winter or early spring, before the onset of the growing season. Use a balanced, slow-release fertilizer that can provide a steady supply of nutrients throughout the year. Apply the fertilizer according to the package instructions, ensuring even distribution around the base of the shrub without making direct contact with the stems or roots.
Adequate fertilization will not only enrich the soil but also enhance the distinctive foliage colors and contribute to the health of the plant. As this variety is known for its upright to bushy growth habit and eventual height of up to 4 meters, consistent fertilization will help maintain its robust form and prolific fruiting characteristics.
