When pruning, ensure you use a clean, sharp pair of scissors or pruners to prevent damage to the plant's stem.
Propagation of Streptocarpus saxorum Engl.
Streptocarpus saxorum Engl. can be propagated by several methods which include:
Seeds propagation
Seeds collected from the seed capsules after the flowers have wilted can be used to propagate new plants. Once collected, the seeds should be sown on a moist, well-draining soil mix and should be covered lightly with soil. The seeds should be kept in a warm and bright environment and should be watered regularly. Germination usually occurs in 2-3 weeks.
Leaf-cutting propagation
Propagation by leaf-cutting is another method that can be used to produce new plants. The leaves of the Streptocarpus saxorum Engl. should be cut as close to the base as possible and should be inserted vertically into a moist soil mix. The soil should be kept moist and the leaves should be kept in a warm and bright environment for the roots to develop.
Division propagation
Division of the rhizome is another method that can be used to propagate the plant. When the plant has grown and formed a clump, the clump can be divided into several smaller pieces with each piece having a portion of the rhizome and leaves. The smaller pieces can then be planted in separate containers with a well-draining soil mix and should be kept in a warm and bright environment for the roots to develop.
All propagation methods for Streptocarpus saxorum Engl. require adequate moisture, warmth and bright light to be successful. Once new roots have developed, the new plant should be kept in a well-lit area and the soil should be kept moist but not overly saturated to prevent root rot.
Disease and Pest Management for Streptocarpus saxorum Engl.

- Leaf spot: This fungal disease can cause brown or black spots on leaves. Remove and destroy infected leaves and avoid overhead watering.
- Rust: Rust appears as yellow or brown spots on the leaves. Remove and destroy infected leaves and avoid overcrowding plants.
- Botrytis blight: This fungal disease can cause brown spots and fuzzy gray mold on leaves and flowers. Remove and destroy infected leaves and flowers and provide good air circulation.
- Root rot: Overwatering or poorly drained soil can lead to root rot, which can cause the plant's roots to turn brown and mushy. Improve drainage and avoid overwatering the plant.
Common Pests
Some common pests that can affect Streptocarpus saxorum Engl. include:
- Aphids: These tiny insects can suck the sap from the plant's leaves, causing them to turn yellow and stunted. Wash them off with a strong stream of water or use an insecticidal soap.
