Fertilising a Corylus
To support robust growth and ensure a bountiful harvest of nuts, it is recommended to fertilize Corylus shrubs annually. Apply a balanced, slow-release fertilizer in early spring, just as the plant begins to break dormancy. This will provide the shrub with essential nutrients throughout the growing season. Be cautious not to over-fertilize, as this can lead to excessive foliage growth at the expense of fruit production.
When applying fertilizer, spread it evenly around the base of the plant, extending out to the drip line. This method ensures that the root system, which spreads outward, has access to the nutrients. After fertilizing, water the area thoroughly to help distribute the fertilizer into the soil and reduce the risk of root burn. With proper nutrition, Corylus will thrive, offering a delightful display of flowers in spring and a generous yield of hazelnuts in the autumn.
