Propagation methods of Adiantum capillus-veneris L. var. modestum (Underwood) Fern.
Adiantum capillus-veneris L. var. modestum (Underwood) Fern., commonly known as Southern maidenhair fern, is a perennial plant that belongs to the family Pteridaceae. Propagation of this plant can be done through spores, division, or stem cuttings.
Propagation by spores
Propagation by spores is the most natural way of increasing the plant population. Spores are produced on the underside of the fronds and can be collected when mature. Spores need a suitable growing medium to germinate, and most commonly used media are peat-based or sphagnum moss-based. The spores are sown on the surface of the growing medium and covered with a clear plastic lid to maintain high humidity. After a few weeks, small green heart-shaped leaves will appear indicating the successful growth of new ferns.
Propagation by division
Propagation by division is an easy way of propagating Adiantum capillus-veneris L. var. modestum (Underwood) Fern. This method can only be performed on established clumps. The clump is carefully dug out of the ground and divided into sections, including at least one healthy rhizome and a portion of the frond. The divided sections are planted into suitable pots filled with a growing medium, preferably a well-draining soil mixture with added sand and peat moss. The newly planted ferns are then watered thoroughly and placed in a shaded area until new growth appears.
Propagation by stem cuttings
Propagation by stem cuttings is an alternative option if no established clumps are available. This method should be done during the spring or summer when the plant is actively growing. Stem cuttings should be around 10 cm in length and should have at least two fronds attached. The fronds should be trimmed by half to reduce water loss. The cuttings are then inserted into a soil mixture containing peat moss and sand and kept moist. After several weeks, the cuttings will develop roots and new growth, indicating successful propagation.
