Fertilising a Buxus sempervirens
To ensure a lush and dense box hedge, regular fertilization is essential. Buxus sempervirens benefits greatly from a balanced, slow-release fertilizer applied in early spring. This application provides essential nutrients that support new growth, which is particularly important given its modest annual growth rate of 10-20 cm. A second application in mid-summer can help sustain its vibrant green foliage throughout the growing season.
An ideal fertilizer for this evergreen hedge would contain a mix of nitrogen, phosphorus, and potassium, along with trace elements to promote strong root development and robust health. By adhering to this fertilizing regimen, gardeners can help ensure that their box hedge remains a vibrant and hardy boundary or garden feature, even during the colder months, thanks to its notable winter hardiness.
