Propagation of Geigeria ornativa O.Hoffm. subsp. orientalis Wild.
Geigeria ornativa O.Hoffm. subsp. orientalis Wild. can be propagated through various methods. The following are some of the most effective methods:
Seed Propagation
Geigeria ornativa O.Hoffm. subsp. orientalis Wild. can be propagated by seed, which should be done in spring or early summer. The seeds should be sown in a well-draining soil mix, and lightly covered with soil. The soil should be kept moist, but not waterlogged. Germination should occur within 2-3 weeks. Once the seedlings have emerged, they should be kept in a warm, bright location, but protected from direct sunlight. When the seedlings are large enough to handle, they should be potted up into individual containers.
Cuttings
Geigeria ornativa O.Hoffm. subsp. orientalis Wild. can be propagated by stem cuttings taken in spring or early summer. The cuttings should be taken from healthy, mature plants, and should be around 10cm long. The bottom 2cm of the cutting should be dipped in a rooting hormone, and inserted into a well-draining soil mix. The soil should be kept moist, but not waterlogged. The cuttings should be kept in a warm, bright location, but protected from direct sunlight. Rooting should occur within 4-6 weeks. Once the cuttings have rooted, they should be potted up into individual containers.
Division
Geigeria ornativa O.Hoffm. subsp. orientalis Wild. can also be propagated by division. This should be done in spring, just as new growth is starting. The plant should be carefully lifted from the ground, and the root ball should be divided into smaller clumps using a sharp, clean knife. Each clump should have several shoots and a good root system. The clumps should be planted into well-draining soil, and kept moist until they are established.
Disease and Pest Management for Geigeria ornativa O.Hoffm. subsp. orientalis Wild.
