Fertilising a Polystichum setiferum
For optimal growth and health, Polystichum setiferum benefits from regular fertilization. Fertilize this species in early spring to support vigorous foliage development. A balanced, slow-release fertilizer formulated for evergreen plants is ideal, as it provides a steady supply of nutrients throughout the growing season. Apply according to the package instructions, ensuring even distribution around the base of the plant to encourage an upright and bushy growth habit.
It is crucial that the soil remains humus-rich, thus complementing the feeding with a top dressing of well-rotted compost or leaf mold can be beneficial. This practice not only enriches the soil but also maintains the necessary soil structure and moisture levels for the plant's average water needs. Fertilization should be light to prevent excessive growth, which can compromise the plant's natural hardiness.
