Streptocarpus saxorum, commonly known as Cape Primrose, is a semisucculent perennial plant native to the seasonally dry tropical climates of Africa. It belongs to the family Gesneriaceae and the genus Streptocarpus. This plant is known for its attractive, tubular flowers and fuzzy leaves. It has a dormancy period of about 2 months during which it requires less water.
Streptocarpus saxorum thrives in bright, indirect light and moderate temperatures. It prefers a humid environment but can tolerate average household humidity levels. Water the plant when the top layer of soil feels dry, but avoid letting it sit in water. During its dormancy period, reduce watering.
土壌
This plant prefers well-draining loam soil. A mix of peat, perlite, and vermiculite works well. Ensure the soil is kept slightly moist but not waterlogged to prevent root rot.
肥料
Use a balanced fertilizer with an N-P-K ratio of 10-10-10. Fertilize every 4-6 weeks during the growing season. Reduce or stop fertilizing during the dormancy period.
植え替え
Repot Streptocarpus saxorum every 1-2 years or when it outgrows its pot. Choose a pot that is slightly larger than the current one and ensure it has good drainage. Repot in the spring before the growing season begins.
伝搬
Propagate Streptocarpus saxorum through leaf cuttings or division. The best time to propagate is during the spring or early summer. Place the cuttings in a moist, well-draining soil mix and keep them in a warm, humid environment until they root.
剪定
Prune the plant to remove dead or yellowing leaves and spent flowers. This helps to encourage new growth and maintain the plant's shape. Pruning is best done during the growing season.
毒性
Streptocarpus saxorum is not known to be toxic to pets or humans. However, it is always a good practice to keep plants out of reach of pets and children.
追加
To encourage blooming, ensure the plant receives adequate light and is not overwatered. Regularly check for pests such as aphids and spider mites, and treat them promptly if found.
