Germination
To germinate Bolusanthus speciosus seeds, start by preparing a seed starting tray or small pots with a well-draining seed starting mix, such as a blend of peat moss and perlite. Sow the seeds on the surface of the soil and lightly press them into the mix. Bolusanthus speciosus seeds require light for germination, so avoid covering them with additional soil. Keep the soil consistently moist but not waterlogged by misting regularly or using a gentle watering can. Place the tray or pots in a warm location with indirect sunlight, maintaining a temperature between 70-80°F (21-27°C). Germination typically occurs within 4-6 weeks. Once the seedlings emerge, provide them with ample light and gradually acclimate them to outdoor conditions if transplanting. Bolusanthus speciosus prefers full sun and well-drained soil. Continue to care for the seedlings with proper watering and light as they grow into mature plants.
