Description
Othonna capensis, commonly known as “Ruby Necklace” or “String of Rubies,” is a succulent native to South Africa. It is especially prized for its bright green to purple, cylindrical leaves and its small yellow flowers, which add a charming and exotic touch to any home or garden.
Here are some care tips to keep your plant healthy:
Light
Othonna capensis prefers bright, indirect light. It can tolerate a few hours of direct sunlight, especially in the morning or late afternoon, but avoid intense midday sun, which can scorch its delicate leaves. An east- or west-facing window is ideal.
Watering
Like most succulents, it requires moderate watering. Water only when the soil is completely dry — about every 2 to 4 weeks, depending on conditions. Make sure the pot has drainage holes to prevent water buildup, which can cause root rot. In winter, reduce watering frequency as the plant enters dormancy.
Humidity
This plant adapts well to normal indoor humidity. It doesn’t need high humidity and may even suffer in overly damp environments. Provide good air circulation to prevent mold or fungal issues.
Temperature
Orostachys iwarenge thrives in temperatures between 15°C and 26°C (59–79°F). It can tolerate slightly cooler temperatures but should be protected from frost and cold drafts, which can damage its leaves.
Soil
A well-draining soil mix is essential. Use a cactus or succulent potting mix, or make your own by combining standard potting soil with coarse sand or perlite to improve drainage.
Fertilization
Feed once a month during the growing season (spring and summer) with a balanced succulent fertilizer, diluted to half strength. Stop fertilizing in autumn and winter when the plant becomes dormant.
Pruning
Pruning is rarely necessary. You can remove dead or damaged leaves to keep the plant tidy and improve air circulation. Othonna capensis also propagates easily from stem cuttings.
Common Problems
Watch for signs of overwatering, such as soft or translucent leaves, or insufficient light, indicated by pale or discolored foliage. Mealybugs and aphids are the most common pests and can be controlled with a suitable treatment, such as a biological insecticide or by wiping the leaves with a cloth dipped in alcohol.
