Soil Requirements
The Hairy Brachystelma does not require a specific type of soil, but it should have good drainage capabilities to avoid waterlogging, which can cause root rot. It prefers well-draining soil rich in organic matter, such as a mix of peat moss, sand, and perlite in equal amounts. Moreover, it is highly sensitive to chemicals and prefers the soil with a pH level between 6.0 to 7.0.
Cultivation Methods
The Brachystelma hirsutum E.Mey. plant thrives in well-draining soil and requires moderate temperatures. It is best to cultivate it indoors or in a greenhouse to protect it from extreme weather conditions and pests. The plant also requires partial shade, ensuring it does not receive direct sunlight for prolonged periods.
Watering Needs
The Brachystelma hirsutum E.Mey. plant requires regular watering, but it is important to avoid overwatering. The soil should be moist, and the plant must receive enough water to prevent the soil from drying out completely. Water the plant when the top layer of soil appears dry.

Prune back any overgrown stems that are getting too big for the plant, carefully cutting the stem above a leaf node to encourage healthy regrowth.
Propagation of Brachystelma hirsutum E.Mey.
Brachystelma hirsutum E.Mey. belongs to the Asclepiadaceae family and is a succulent perennial plant native to southern Africa. Propagation of this plant can be done by several methods, including:
Division
The plant can be propagated by division during its growing season. Carefully remove the plant from its pot or garden bed, and divide it into smaller sections, ensuring that there are enough roots and leaves on each division. Plant each division in its own pot or garden bed with well-draining soil and water it thoroughly.
Leaf cuttings
Brachystelma hirsutum E.Mey. can also be propagated from leaf cuttings. Take a healthy leaf from the plant and make a clean cut at the base. Allow the leaf to dry for a day or two, then dip the cut end in rooting hormone. Plant the leaf in a pot or garden bed with well-draining soil and water it thoroughly. Keep the soil moist but not waterlogged, and new shoots should emerge within a few weeks.
Stem cuttings
An alternative method for propagating Brachystelma hirsutum E.Mey. is through stem cuttings. Take a healthy stem from the plant, making sure it has several leaf nodes. Trim the stem to remove any flowers or buds, then dip the cut end in rooting hormone. Plant the cutting in well-draining soil and water it thoroughly. Keep the soil moist but not waterlogged, and new shoots should emerge within a few weeks.
Propagation of Brachystelma hirsutum E.Mey. can be a rewarding experience for gardeners and is an excellent way to propagate the plant to share with friends and family.
