Fertilising a Corylopsis spicata
To ensure the spike witch hazel flourishes, fertilizing should be approached with care. It is advantageous to apply a balanced, slow-release fertilizer in early spring, as the shrub breaks dormancy. This will support the development of its striking yellow blooms and the red to green transition of its foliage in spring. If desired, a second application of fertilizer can be given in late spring to bolster the growth through the summer months.
The species adapts to various soil types but thrives in well-drained conditions. Over-fertilization can lead to excessive growth at the expense of flowers, so it is essential to adhere to the recommended amounts. A moderate approach to fertilizing will maintain the plant's natural upright to bushy habit and contribute to its overall health and vigor.
