Stem cutting propagation
Propagation of Euphorbia confinalis R.A.Dyer subsp. rhodesiaca L.C.Leach can also be done through stem cuttings. Take a cutting from a mature plant with a sharp, sterile knife and allow the cut to dry for a few days before planting. Plant the cutting in a well-draining soil mix and water sparingly until roots develop. Once the plant has established roots, it can be transplanted into its permanent container.
Division
Division is another method by which Euphorbia confinalis R.A.Dyer subsp. rhodesiaca L.C.Leach can be propagated. This method involves dividing the plant into smaller sections and planting the sections in individual containers. Care should be taken to ensure that each section has sufficient roots and foliage to support its growth.
Propagation of Euphorbia confinalis R.A.Dyer subsp. rhodesiaca L.C.Leach can be a rewarding experience and can help to expand your collection of succulent plants.
