Amphinomia brachyantha requires a well-draining potting mix to thrive. A mix of peat moss, perlite, and vermiculite in equal proportions is recommended, or any mix that contains a high percentage of organic matter. The soil should be kept slightly moist at all times but should not be allowed to become waterlogged, as this can lead to root rot. The plant should be repotted every two to three years to ensure healthy growth, and fertilized every 6 months with a slow-release fertilizer.
Cultivation Methods for Amphinomia brachyantha (Harms) A.Schreib.
Amphinomia brachyantha (Harms) A.Schreib. is commonly found in Southeast Africa and is relatively easy to cultivate. The plant requires a well-draining soil mix, but it can tolerate a wide range of soil types, including sandy, loamy, and clay soil. The best location to plant the Amphinomia brachyantha is in an area that receives partial to full sun.
When propagating the plant, it's best to use cuttings or seeds. If you're starting the plant from cuttings, dip the cutting in rooting powder, then plant it in moist soil, and cover it with a plastic bag to create a humid environment to stimulate roots' growth. For seedlings, plant the seeds in a seed-starting soil mix and water gently to prevent the soil from becoming too soggy.
Watering Needs for Amphinomia brachyantha (Harms) A.Schreib.
While Amphinomia brachyantha is a drought-tolerant plant, it still requires watering regularly. Water the plant when the soil is dry to the touch, but ensure that you avoid watering too much to prevent root rot.

Additionally, ensure that the plant has adequate calcium and magnesium in the soil by adding Epsom salt to the soil once a month.
Pruning Amphinomia brachyantha (Harms) A.Schreib.
Amphinomia brachyantha does not require frequent pruning, but it's essential to trim it to maintain its size or shape. The best time to prune the plant is in early spring before the growing season begins. Use clean and sharp pruning shears to cut back any overgrown branches or stems. Additionally, remove any dead or damaged foliage to prevent it from spreading to other parts of the plant.
Propagation of Amphinomia brachyantha
Amphinomia brachyantha (Harms) A.Schreib. propagates primarily through vegetative methods. The potential propagation methods are:
Stem Cuttings
This plant can propagate through stem cuttings taken from mature, healthy stems. Cuttings should be 3-5 inches long and should have several nodes. Remove the lower leaves and any flower buds, dust with rooting hormone, and plant in a well-draining potting mix. Keep the soil evenly moist and provide bright, indirect light. Roots should develop within 4-6 weeks, and the new plant can be transferred to a permanent pot and soil.
Division
Amphinomia brachyantha can propagate by dividing established clumps. Dig up the entire plant, brush off excess soil, and gently separate the clumps by hand or with a sharp knife. Each clump should have a few healthy roots and shoots. Replant the divided clumps in a well-draining potting mix, with the crown of the plant just above the soil surface. Water well and provide bright, indirect light.
