Propagation of Pterocarpus angolensis DC.
Pterocarpus angolensis DC., also known as the Bloodwood tree, is a deciduous tree native to southern Africa. It is often used for lumber, as well as traditional medicine. The tree can be propagated through several methods.
Seed Propagation
Propagation by seed is relatively easy but requires patience as the plant grows slowly. Seeds should be collected during the fruiting season and soaked in hot water to help soften the outer seed coat. After soaking, seeds are planted in well-draining soil and kept moist. Germination may take up to several months. After germination, seedlings can be transplanted to individual pots or gardens.
Cuttings
Cuttings may also be used to propagate Pterocarpus angolensis DC. Softwood cuttings can be taken during the growing season and treated with rooting hormone before planting in soil. Hardwood cuttings can be taken in the fall or winter and should be planted in a rooting medium indoors and kept in a warm, humid environment until they begin to root.
Air Layering
Air layering may be a reliable method of propagation for Pterocarpus angolensis DC. Select a healthy, mature branch from the tree and remove a small section of bark at the desired rooting location. Apply rooting hormone to the wound and wrap with moist sphagnum moss. Wrap the moss with plastic or aluminum foil to keep it moist, and wait for roots to form. Once the roots are established, cut the branch below the air layered area and plant in soil.
Overall, Pterocarpus angolensis DC. can be propagated through seed propagation, cuttings, and air layering. Each method has its own benefits and limitations, and the grower should choose the method that best suits their needs and resources.
Disease and Pest Management for Pterocarpus angolensis DC.
