Streptocarpus saxorum is easy to grow and quite robust. It will do well as a pot plant indoors or outdoors, and can be planted in a warm, sheltered, shady spot in the garden. Ensure a warm spot with fertile, leafy, humus-rich soil that is moist but well drained with good light but no direct sunlight. Streptocarpus in general are frost tender and are also very sensitive to light. They are burned easily by the sun and flower poorly in deep shade, but S. saxorum can tolerate some direct sun without suffering. Light shade is best for growing healthy plants with plenty of flowers.

Good ventilation is required to prevent fungal infections indoors but if grown outdoors protect plants from any drying winds by mulching with compost of leaf mould. Regularly remove all dead, unhealthy, dying leaves and flowers as these encourage fungal growth. This will also help to keep the plants looking attractive and healthy.

Watering Streptocarpus should be done with care. It is very important that the plants should not be over-watered to prevent rotting and fungal problems. They have quite shallow root systems - in nature they often thrive in very little soil so allow them to get quite dry between watering. Grow in pots in a loam-based peat compost mix. During the warm summers when they are actively growing they need plenty of water. Most of the streptocarpus' 'rest' during winter and this slight dormancy will cause them to need very little water during this time so be sure to reduce the amount given. Regular feeding during growing season with liquid foliar feed is recommended. Repot once the plant's roots appear at the bottom of the pot.

When sowing seed in spring, mix a pinch of the dust-like seed with a small amount of sand to assist with spreading the seed evenly and to prevent sowing too densely. Use a well drained medium that is not too coarse. Cover with a very thin covering of sand. Keep out of direct sun but in warmth. Germination usually takes 3-4 weeks, it is important to not allow the seedlings to dry out so water regularly with a fine spray. Plant the seedlings into small pots only once they are quite big and strong. Transplant again into bigger pots when the roots have filled the small pots.

Streptocarpus saxorum is easily propagated from stem-tip cuttings taken at any time of year. A variety of mediums can be used as long as they are well drained. Sand, bark, palm fibre and polystyrene or vermiculite in different ratios are all suitable. At Kirstenbosch we use 1 part bark:1 part polystyrene. Water the medium well and treat with a suitable fungicide before using. Plant several rooted cuttings per pot to create a full display.

Plants that have grown quite large can also be divided as a method of increasing them, do this in early spring and repot to grow on. Mature plants can lose their vigour after 3 to 5 years and propagation as described above can be used to replaced them with younger plants.

Caterpillars and mealybug are the most troublesome pests on the Streptocarpus, they can either be hand collected or sprayed with a suitable poison.
