Fertilising a Polystichum polyblepharum
To ensure optimal vitality and the lush greenery characteristic of Polystichum polyblepharum, it is crucial to provide the right nourishment. Fertilize this species in early spring, just as the new fronds begin to unfurl. Utilize a balanced, slow-release fertilizer that will steadily supply nutrients throughout the growing season.
Given its preference for humus-rich soil, incorporating organic matter into the soil can also be beneficial. This not only improves soil structure and fertility but also mimics the plant's natural environment, promoting healthier growth. When applying fertilizer, be sure to follow the instructions specified for shade-tolerant ferns, as over-fertilization can lead to poor plant health and growth. An annual application is generally sufficient to maintain a robust and vibrant clump of this evergreen fern.
