Introduction
Streptocarpus rexii, also known as the Cape Primrose, is a popular houseplant native to South Africa. It is prized for its beautiful, trumpet-shaped flowers and attractive foliage. This guide will provide you with all the information you need to grow and care for your Streptocarpus rexii plant.
Plantation
-
Location: Streptocarpus rexii prefers bright, indirect light. Avoid direct sunlight, as it can cause leaf burn.
-
Soil: Use well-draining, fertile potting mix. A mix of equal parts peat moss, perlite, and vermiculite is ideal.
-
Pot: Select a pot with drainage holes to prevent waterlogging. A pot slightly larger than the root system is suitable.
Growing
-
Watering: Keep the soil consistently moist but not waterlogged. Allow the top inch of soil to dry out before watering again.

-
Humidity: Streptocarpus rexii prefers moderate humidity levels, around 50-60%. Place a humidifier or a pebble tray filled with water nearby to maintain humidity.

Fertilization: Apply a balanced, water-soluble fertilizer every two weeks during the growing season, and reduce to once a month during winter.
Care
-
Pruning: Remove dead or yellowing leaves and spent flowers to encourage new growth.
-
Pest control: Inspect the plant regularly for common pests like aphids, spider mites, and whiteflies. Use insecticidal soap or neem oil to treat infestations.
