Fertilising a Dryopteris filix-mas
To sustain the vigorous growth and lush greenery of Dryopteris filix-mas, a balanced approach to fertilization is essential. Apply a slow-release, balanced fertilizer at the beginning of the growing season, typically in early spring. This will provide a steady supply of nutrients as the fronds unfurl and gain strength. A second application can be made during midsummer to support continued growth and maintain the plant's vitality.
It's important to ensure that the fertilizer is evenly distributed around the base of the plant, avoiding direct contact with the fronds to prevent burn. Watering the plant after fertilizing helps to distribute the nutrients into the soil, allowing the roots to absorb them more effectively. This two-pronged fertilization strategy will contribute to a robust and healthy Dryopteris filix-mas throughout its growing season.
