Welsh polypody is a tough, adaptable fern that thrives in partial shade with consistently moist, well-drained soil. It tolerates cooler temperatures and is well-suited to shaded rock gardens, woodland borders, or containers indoors. Minimal fertilization is needed — a light feed in spring is sufficient to keep fronds lush.
