Propagation of Selago appressa E.Mey.
Selago appressa E.Mey. is a small, evergreen shrub that belongs to the family Scrophulariaceae. It is widely distributed throughout South Africa, from the Western Cape to the Eastern Cape provinces. The plant is commonly known as the Cape dwarf-umbrella bush and is grown for its attractive foliage and delicate flowers.
Propagation methods
Propagation of Selago appressa E.Mey. can be done through several methods, including:
- Seeds: The plant produces small, brown seeds that are enclosed in a capsule. To propagate through seeds, sow them in a well-draining soil mix in late spring or early summer. Keep the soil moist until the seeds germinate, which should take about 2-4 weeks. After germination, move the seedlings to individual pots and grow them until they are large enough to be planted in their permanent location.
- Cuttings: Softwood cuttings can be taken from the current year's growth for propagation. Choose healthy stems and cut them to a length of about 6-8 cm. Remove the lower leaves and dip the cut end in rooting hormone powder. Insert the prepared cuttings in a well-draining potting mix and cover them with a plastic bag or a propagator. Place the container in a warm, bright location and keep the soil moist. The cuttings should root in about 4-6 weeks, after which they can be transplanted to individual pots.
- Division: Selago appressa E.Mey. can also be propagated through division. This is usually done in early spring when the plant is just starting to grow. Gently dig up the plant and separate the root clumps into several sections. Each section should have some healthy stems and roots. Plant the divided sections in soil amended with compost and keep the soil moist until the plants are established.
