Fertilising a Corylus maxima 'Purpurea'
To maintain the striking purple foliage and support healthy fruit production, it's essential to fertilize Corylus maxima 'Purpurea' annually. Early spring, just before the onset of new growth, is the ideal time for this task. A balanced, slow-release fertilizer, rich in nitrogen, potash, and phosphorus, is recommended to promote lush foliage and robust development.
Apply the fertilizer around the base of the shrub, taking care to avoid direct contact with the stems. Water the area thoroughly after application to help distribute the nutrients into the soil. This not only sustains the shrub's vibrant color throughout the growing seasons but also bolsters its vigor, aiding in the production of quality fruits come autumn.
