Fertilising a Cupressocyparis leylandii
To ensure that Cupressocyparis leylandii achieves its full potential, regular fertilization is key. Due to its robust growth rate, this species benefits greatly from the application of a balanced fertilizer. It is recommended that you apply a granular, slow-release fertilizer designed for evergreen hedges in early spring. This will provide a steady supply of nutrients throughout the growing season, supporting the plant's need for energy as it reaches heights between 70 and 100 centimeters annually.
A second application of fertilizer in mid-summer can help maintain its vibrant green foliage and overall health. Be cautious not to over-fertilize, as this can lead to excessive growth, making the plant more susceptible to winter damage in colder zones.
