Fertilising a Asplenium scolopendrium
To support the lush, green foliage of Asplenium scolopendrium, it benefits from occasional fertilization. During the growing season, particularly in spring and early summer, applying a balanced, slow-release fertilizer can enhance the plant's vigor. It is recommended to provide a light feeding with a fertilizer that's well-suited for ferns or a generic houseplant formula, ensuring it is diluted to half the recommended strength to avoid over-fertilization, which can be detrimental to the plant's health.
When applying fertilizer, distribute it evenly around the base of the plant, taking care not to come into direct contact with the fronds. Watering the plant after fertilizing will help to distribute the nutrients to the roots and reduce the risk of root burn. This species, with its preference for well-drained soils and shady locations, will respond favorably to this feeding regime, maintaining its ornamental appeal throughout the year.
