Propagation of Dissotis irvingiana Hook.f. forma abyssinica (Gilg) A.Fern. & R.Fern.
The most common method of propagation for Dissotis irvingiana Hook.f. forma abyssinica (Gilg) A.Fern. & R.Fern. is through seed germination. The seeds must be collected when they are fully matured and carefully cleaned to remove any debris. After cleaning, the seeds can be sown in a nursery bed or container filled with well-draining soil. The soil must be constantly moist but not waterlogged and kept in a warm location with indirect sunlight.
Another technique that can be used for propagation is through softwood cuttings. Cuttings must be taken during the active growing season, and the chosen stems must be free of disease and damage. Cuttings should be 10-15cm in length and contain at least three nodes. After removing the lower leaves, the cuttings should be dipped in a rooting hormone and planted in a well-draining potting mix. The cuttings should be kept in high humidity and indirect sunlight until roots have developed.
Dissotis irvingiana Hook.f. forma abyssinica (Gilg) A.Fern. & R.Fern. can also be propagated through division. This technique is commonly used to rejuvenate older plants. The plant should be carefully dug up, and the root ball separated into smaller portions. Each portion should have healthy roots and an appropriate amount of foliage. The divided plants should be planted immediately and kept in a location with indirect sunlight and constantly moist soil.
