Cutting Propagation
Cuttings taken from Lasiosiphon burchellii Meisn. can root easily when provided with ample moisture and warmth. Cuttings should be taken from the softwood of the plant and must be dipped in rooting hormone before being planted. The cuttings should then be planted in a mix of sand and compost and kept in a humid area. The ideal temperature for rooting is between 18-20°C. Once roots start to appear, the cuttings can be transplanted into a potting mix.
