Fertilising a Carpinus betulus
Ensuring the health and vigor of a Carpinus betulus hedge starts with proper nutrition. Fertilize Carpinus betulus in early spring before the onset of new growth. A balanced, slow-release fertilizer, rich in nitrogen, promotes lush, green foliage essential for a dense hedge. Apply according to the manufacturer's instructions, avoiding over-fertilization, which can lead to excessive growth and reduced winter hardiness.
A second application can be beneficial in late spring or early summer, coinciding with the hedge's rapid growth phase. This supplementary feeding supports the plant's development and prepares it for the colder months, aligning with its notable winter hardiness, which can withstand temperatures down to -26.1°C, classified within USDA zone 5a. Proper fertilization not only enhances visual density but also fortifies the plant against environmental stressors.
