Each section should have leaves and roots. The sections can then be replanted in a well-draining soil mix.
Cuttings Propagation
Cuttings propagation can also be used to propagate Luzula arctica Blytt ssp. latifolia (Kjellm.) Porsild. This method involves taking a cutting from an established plant and planting it in a well-draining soil mix. The cutting should have at least one node where roots can form. Cutting propagation is best done in the spring or early summer when the plant is actively growing. The cutting should be kept moist and in a shaded area until new growth appears, indicating that roots have formed.
Overall, Luzula arctica Blytt ssp. latifolia (Kjellm.) Porsild is a hardy plant that can be easily propagated through various methods, allowing gardeners to expand their collection and enjoy this beautiful and useful plant.
