Propagation of Antirrhinum kingii S. Wats. var. watsonii (Vasey & Rose) Munz
Antirrhinum kingii S. Wats. var. watsonii (Vasey & Rose) Munz can be propagated through various methods, including:
1. Seed Propagation
Seeds can be collected from mature fruit capsules that have turned brown and dry. The seeds should be collected and sown immediately to ensure maximum germination rates. The seeds should be sown in seed trays filled with a well-draining potting mix. The sowing depth should be no more than 2-3 times the diameter of the seed. The trays should be placed in a warm and bright location until germination occurs. The young seedlings can be transplanted to individual pots once they have developed their second set of true leaves.
2. Stem Cuttings Propagation
Stem cuttings from Antirrhinum kingii S. Wats. var. watsonii (Vasey & Rose) Munz can also be propagated. Softwood cuttings should be taken from the plant's new growth in the spring. The cutting should be approximately 6-8cm long and should be removed just below a node. The lower leaves should be removed, and the cutting should be dipped into a rooting hormone. The cutting should be placed in a well-draining potting mix and kept in a humid environment. Rooting usually occurs within 3-4 weeks.
3. Division Propagation
Antirrhinum kingii S. Wats. var. watsonii (Vasey & Rose) Munz can also be propagated through division. This is best done in the spring. The plant should be dug up, and the root ball divided into several sections. Each section should have a healthy root system and at least one shoot. The divided plant should be replanted in a location with well-draining soil and kept moist until new growth appears.
