Streptocarpus: A Guide to Growing and Caring for Cape Primrose
Introduction
Streptocarpus, also known as Cape primrose, are beautiful houseplants that are easy to grow and care for. They are native to South Africa and are prized for their lush green leaves and vibrant, primrose-like flowers.
Growing Conditions
Streptocarpus thrive in bright, indirect light, similar to what they would receive in their natural mountain habitats. They prefer warm temperatures and high humidity, so a bathroom or kitchen is an ideal location.
Watering
Water Streptocarpus regularly, allowing the top few centimeters of soil to dry out before watering again. Avoid overwatering, as this can lead to root rot.
Fertilizing
Feed Streptocarpus every two weeks during the growing season with a balanced fertilizer.
Repotting
Repot Streptocarpus every spring into a slightly larger pot with fresh potting mix. Make sure the pot has drainage holes to prevent waterlogging.
Propagation
Streptocarpus can be easily propagated from leaf cuttings. Simply remove a healthy leaf from the plant and insert the stem into moist potting mix.
Troubleshooting
- Wilting: Overwatering or underwatering. Adjust watering frequency accordingly.
- Few flowers: Insufficient light. Move the plant to a brighter location.
- Brown leaf tips: Underwatering. Water more frequently.
- Grey mold: Remove affected leaves and treat with a fungicide.
- Mealybugs: Remove affected leaves and spray with an organic insecticide.
