Barleria rogersii  can be propagated by seed or cuttings.

To prevent seed being lost it can be collected as the capsules turn brown and before they explode.The seeds should be planted in a mixture of two parts good soil and one part clean river sand. Place the container in a shady spot in your garden and water once a week.

Germination of the seeds takes place within a week. Transplanting the seedlings into bags should be done when the seedlings are more or less 100 mm high.

Cuttings should be made in summer, making use of softwood plant material. Take cuttings 70-120 mm long, treat with a hormone powder and plant in a mixture of even parts good soil and river sand. Put the cuttings in a shady place and water twice a week. Transplant the rooted cuttings after about three months into a good soil mixture.
