Care Instructions for Streptocarpus

To ensure your streptocarpus plants thrive and produce beautiful blooms, it’s crucial to provide them with the right care. Here are some care instructions to keep in mind:

Light Requirements

Streptocarpus plants prefer bright, indirect light. Placing them near an east-facing or west-facing window is ideal to provide them with the necessary light without exposing them to direct sunlight. If you only have a south-facing window, you can use a sheer curtain to diffuse the intense sunlight.

Watering and Humidity

Proper watering is essential for streptocarpus plants. Water them when the top inch of soil feels dry to the touch. Avoid overwatering as it can lead to root rot. Using room temperature water is recommended to prevent shock to the plant. Additionally, avoid watering the leaves and flowers to prevent fungal diseases.

Maintaining proper humidity levels is also important for streptocarpus plants. You can increase humidity by placing a tray of water nearby or using a humidifier to ensure the air around the plant is adequately moist.

Soil and Fertilizer

Streptocarpus plants prefer well-draining soil that is rich in organic matter. A soil mix of peat moss, perlite, and vermiculite or a pre-made African violet soil mix works well for them. The ideal pH level for the soil is between 5.5 and 6.5.

Fertilize your streptocarpus plants every two weeks during the growing season using a balanced fertilizer high in phosphorus and potassium, and low in nitrogen. Dilute the fertilizer to half the recommended strength to avoid over-fertilization. During the dormant season, fertilization is not necessary, except for certain varieties like the ‘Crystal’ series, which can benefit from a quarter-strength tomato food.

Temperature and Air Circulation

Streptocarpus plants prefer moderate to cool temperatures. The ideal temperature range is between 60°F and 75°F (15°C – 24°C). Avoid exposing them to extreme temperature changes, drafty areas, or heat sources as it can cause stress to the plant.

Proper air circulation is crucial to prevent the buildup of harmful bacteria and fungi. You can use a fan to circulate air around the plant, but avoid placing it directly in the path of the airflow.

Propagation Methods for Streptocarpus

If you want to propagate your streptocarpus plants, there are a few methods you can try:

  1. Leaf Cuttings: Cut a healthy leaf in half, removing the central vein. Plant the leaf halves in rich potting soil with the cut side down. Keep the leaf halves moist until they start sprouting. After a few weeks, baby plants will form along the cut edges, and they can be separated and planted in individual pots once they are healthy and growing.

  2. Stem Cuttings: Take a cutting of about 5-10 cm beneath a leaf node. Place the cutting in clean water until it develops roots. Once the roots reach a length of 5 cm, plant the cutting in a soil mixture.

  3. Division: If your streptocarpus plant produces root plantlets, you can separate them from the mother plant and plant them individually.

These propagation methods are relatively straightforward and can help you expand your streptocarpus collection or share the joy of growing these beautiful plants with others.

Common Issues and Solutions

Despite their relatively low maintenance nature, streptocarpus plants can occasionally encounter problems. Here are some common issues and their solutions:

  • Yellowing Leaves: Yellowing leaves can be a sign of overwatering, underwatering, or excessive sunlight exposure. Adjust your watering practices and provide shade if necessary.

  • Brown Leaf Tips: Brown leaf tips can be caused by low humidity or over-fertilization. Increase humidity by misting the leaves or using a humidifier, and avoid over-fertilizing.

  • Root Rot: Root rot can occur due to overly wet soil. To address this issue, remove the affected roots, repot the plant in fresh soil with good drainage, and adjust your watering habits.

  • Pest Infestations: Common pests that can affect streptocarpus plants include spider mites, mealybugs, and aphids. Treat infestations with insecticidal soap or neem oil, following the instructions on the product.

  • Wilting: Wilting can result from insufficient water or exposure to extreme temperatures. Adjust your watering routine and relocate the plant if necessary.

By being attentive to these common issues and taking the necessary steps to address them, you can ensure your streptocarpus plants remain healthy and vibrant.


Streptocarpus plants are an excellent choice for house plant enthusiasts looking to add elegance and color to their indoor spaces. With their stunning blooms, adaptability to different conditions, and relatively low maintenance requirements, they are a joy to care for. Whether you choose the Harlequin Blue, Denim, or any other variety, streptocarpus plants are sure to captivate your heart.

Remember to provide them with bright, indirect light, proper watering, well-draining soil, and a balanced fertilizer. Keep an eye out for common issues, and take appropriate measures when necessary. With these care instructions in mind, you can enjoy the beauty of streptocarpus plants and watch them flourish in your home.
