Aspalathus shawii L.Bolus subsp. longispica (R.Dahlgren) R.Dahlgren can be propagated by seeds or cuttings.
Propagation by Seeds
Seeds should be collected from mature, dry pods. It is best to sow seeds immediately as they may lose their viability quickly. Before sowing, seeds should be treated by immersing them in hot water (80-90°C) for a few seconds to break their dormancy. Then, the seeds should be soaked in water overnight. Plant the seeds in a well-draining growing medium and keep the soil moist until germination, which will usually occur within 2-4 weeks.
Propagation by Cuttings
Cuttings should be taken in spring or summer from semi-hardwood growth. The cuttings should be approximately 10-15cm long with at least two nodes. Remove the lower leaves and dip the cut end in a rooting hormone. Plant the cutting in a well-draining growing medium and water thoroughly. Cover the cutting with a clear plastic bag or place in a propagator to maintain humidity. The cutting should root within 4-6 weeks.
Disease and Pest Management for Aspalathus shawii L.Bolus subsp. longispica (R.Dahlgren) R.Dahlgren
Aspalathus shawii L.Bolus subsp. longispica (R.Dahlgren) R.Dahlgren is a hardy plant that does not usually succumb to diseases or pests. However, it is not completely immune and can be vulnerable under certain conditions.
Common Diseases that Affect Aspalathus shawii L.Bolus subsp. longispica
