Fertilising a Corylus avellana
To support the vigorous growth and fruitful yield of Corylus avellana, an appropriate fertilization regime is recommended. Apply a balanced, slow-release fertilizer to the soil at the base of the shrub in early spring, just as the plant begins to break dormancy. This initial application will provide the necessary nutrients for the burgeoning spring growth and support the development of flowers and, subsequently, nuts.
A second application of fertilizer can be beneficial in late spring or early summer, to sustain the plant's needs throughout the growing season. It is important to follow the manufacturer's instructions regarding the quantity and frequency of fertilizer application to avoid over-fertilization, which could lead to excessive foliage growth at the expense of fruit production. Well-timed and measured fertilization will ensure the hazel remains robust and productive.
