Propagation of Agathosma lancifolia Eckl. & Zeyh.
Agathosma lancifolia Eckl. & Zeyh., commonly known as lance-leaf buchu, is a South African shrub that belongs to the Rutaceae family. The plant is mainly utilized in traditional medicines, cosmetics, and aromatherapy due to the potent essential oils found in its leaves.
The most common methods of propagating Agathosma lancifolia Eckl. & Zeyh. include:
1. Seed Propagation
Propagation through seeds is one of the most commonly used methods for growing Agathosma lancifolia Eckl. & Zeyh. To achieve higher germination rates, it is recommended that the seeds are sown in the early summer season after a period of soaking in water for about 12 hours. After soaking, the seed coat becomes softer, making it easier for the seedlings to emerge.
2. Stem Cuttings
Stem cuttings can be taken from well-established Agathosma lancifolia Eckl. & Zeyh. plants during the summer season. Cuttings of about 7 cm long should be selected, ensuring that they contain two to three nodes. The cuttings should be dipped in a rooting hormone and placed into a well-draining soil mixture. Place the cuttings in a warm, bright spot and water them moderately. After a few weeks, the cuttings should have rooted and can be transplanted in individual pots.
3. Division
Agathosma lancifolia Eckl. & Zeyh. can also be propagated by division. This method involves separating well-established plants into smaller clumps, ensuring that each clump contains a few roots and shoots. The separated plants should be replanted in their preferred soil mixture and watered adequately.
Propagation of Agathosma lancifolia Eckl. & Zeyh. can be relatively easy, but it is important always to use clean equipment and to follow proper handling procedures to prevent the introduction of infective agents. With proper care and attention, a newly propagated plant could take up to two years to become fully established.
