Propagation of Sabicea cauliflora Hiern
Sabicea cauliflora Hiern is a tropical plant that is native to West Africa. It is commonly known as the African sandalwood or sabicea tree. The plant is often grown for its aromatic wood and leaves, which have a pleasant scent when crushed.
Propagation by Seeds
The most common method used to propagate Sabicea cauliflora Hiern is through seeds. The seeds can be obtained from mature fruits that have turned yellow or red. The fruits should be fully ripe before harvesting the seeds.
The seeds can be sown in a seedling tray filled with a well-draining soil mix. Cover the seeds with a thin layer of soil, and then water them lightly. The tray should be placed in a warm, humid place, such as a greenhouse or under a shade tree.
The seeds will germinate in about 2-3 weeks. Once the seedlings have developed two true leaves, they can be transplanted into individual pots.
Propagation by Cuttings
Sabicea cauliflora Hiern can also be propagated by softwood cuttings taken from the parent plant. Softwood cuttings should be taken in the early morning when the plant tissues are turgid and filled with water.
Use a sharp, sterile knife to take a 6-inch cutting from the parent plant. Remove the leaves from the lower half of the cutting, and dip the cut end into a rooting hormone.
The cutting can be planted into a well-draining soil mix or vermiculite. Cover the cutting with a plastic bag or a clear jar to create a mini-greenhouse. Place the cutting in a bright, warm area, avoiding direct sunlight. Keep the soil moist, but not waterlogged.
