Barleria bechuanensis C.B.Clarke benefits from regular pruning to encourage bushier growth and more blooms. After the blooming season, prune the plant back by one-third of its height.
Deadhead spent blooms regularly to encourage more flowers and a longer blooming season.
Propagation of Barleria bechuanensis C.B.Clarke
Barleria bechuanensis C.B.Clarke, also known as Blue Barleria or Bechuanaland Barleria, can be propagated through both seeds and cuttings.
Propagation by Seeds
The seeds of Barleria bechuanensis C.B.Clarke are small and black in color. They can be collected from the plant once they have turned brown and dried on the plant. The collected seeds should be cleaned of any debris and then sown in a well-draining potting mix.
The potting mix should be kept moist, but not waterlogged. The seeds will germinate within 2-3 weeks and can be transplanted to individual pots once they have developed two true leaves.
Propagation by Cuttings
Softwood cuttings of Barleria bechuanensis C.B.Clarke can be taken in the spring or summer. The cuttings should be around 4-6 inches long and taken from the tip of healthy branches. The lower leaves of the cutting should be removed and the remaining leaves should be trimmed to reduce moisture loss.
The cuttings should be dipped in rooting hormone and then planted in a well-draining potting mix. The pot should be covered with a plastic bag to create a humid environment. The cuttings should be kept in bright, indirect light and the potting mix should be kept moist, not waterlogged.
The cuttings will root within 6-8 weeks and can be transplanted to individual pots once they have developed a healthy root system and new growth.
Disease and Pest Management for Barleria bechuanensis C.B.Clarke Plant

The plant is grown for its attractive foliage, showy flowers, and as a hedge or screen plant. As with any plant, Barleria bechuanensis C.B.Clarke is susceptible to various diseases and pests. Here are some of the most common disease and pest management methods that can be employed to protect the plant from damage.
Common Diseases
Root Rot: This disease is caused by waterlogging, which causes the roots to rot. Symptoms include wilting, yellowing and premature leaf drop. To manage root rot, it is essential to improve drainage, avoid overwatering, and remove infected plants.
Powdery Mildew: This disease appears as a white, powdery layer on the leaves. It is caused by fungal spores and thrives in hot, humid conditions. To manage powdery mildew, it is essential to prune infected branches, improve air circulation, and use a fungicide.
Leaf Spot: This disease appears as brown, circular spots on the leaves. It is caused by a fungal infection and thrives in moist conditions. To manage leaf spot, it is essential to prune infected leaves, avoid overhead watering and apply a fungicide.
Common Pests
Aphids: These small, soft-bodied insects are commonly found on the underside of leaves. They damage plants by sucking the sap, which results in stunted growth and distorted leaves. To manage aphids, it is essential to prune infected branches, use a strong jet of water to wash them off or use insecticidal soap.
Spider Mites: These tiny pests spin webs and cause leaves to turn yellow or bronze. They thrive in hot, dry conditions. To manage spider mites, it is essential to increase humidity, prune infected leaves, use a strong jet of water to wash them off or use a miticide.
Whiteflies: These small, white insects damage plants by sucking sap from leaves. They cause the leaves to turn yellow, wilt and drop prematurely. To manage whiteflies, it is essential to prune infected branches, use a strong jet of water to wash them off or use insecticidal soap.
Overall, disease and pest management for Barleria bechuanensis C.B.Clarke involves taking proactive measures like pruning, maintaining proper drainage and irrigation, improving air circulation, and using cultural or chemical methods that are safe and effective. By following these management practices, you can protect your plants and keep them healthy and growing for years to come.
