The Othonna capensis ‘Ruby Necklace’ is a captivating succulent known for its distinctive trailing stems and bead-like foliage. It is a popular choice for hanging baskets or as a vibrant accent, displaying a spectrum of colors that make it a dynamic addition to any plant collection.
Understanding Your Ruby Necklace
The ‘Ruby Necklace’ (Othonna capensis) is also known as ‘String of Pickles’ or ‘Little Pickles’ due to its elongated, fleshy leaves. These leaves, resembling small beads, range from green to vibrant ruby red or purple, with more intense sunlight deepening the reddish hues. The plant also produces small, yellow, daisy-like flowers. Native to the semi-arid regions of South Africa, Othonna capensis stores water in its leaves and stems, tolerating dry conditions.
Caring for Ruby Necklace
Light Requirements
The ‘Ruby Necklace’ thrives in bright, indirect light, which encourages its vibrant coloration. A south-facing window often provides ideal conditions. While it tolerates some direct morning sun, intense afternoon sun can scorch its leaves, so protection during the hottest parts of the day is beneficial. In lower light, the leaves remain greener, with purple highlights primarily on the stems.
Watering Needs
Like most succulents, Othonna capensis requires careful watering to prevent root rot. Water thoroughly until water drains from the pot, then allow the soil to dry completely before the next watering. Overwatering leads to mushy stems and leaves, while underwatering causes shriveling. During active growing seasons in spring and fall, the plant requires more frequent watering than in its dormant winter period.
Soil Mix
A well-draining soil mix is essential for the ‘Ruby Necklace’ to prevent waterlogging and root issues. A standard succulent or cactus potting mix works well, enhanced with amendments like perlite or pumice for improved drainage. The mix should allow excess water to escape quickly. Shallow pots with drainage holes are often preferred due to the plant’s small root system.
Temperature and Humidity
Othonna capensis thrives in average room temperatures, between 60-85°F (15-30°C). It is not frost-tolerant and should be protected from freezing temperatures, ideally brought indoors in colder climates. This succulent does not require high humidity and is content with typical household levels. Good air circulation is beneficial to prevent fungal issues.
Feeding Your Plant
Fertilizing the ‘Ruby Necklace’ is not a frequent requirement, as succulents are low feeders. During its active growing season in spring and summer, apply a balanced liquid fertilizer diluted to half strength every few weeks. Avoid fertilizing during the plant’s dormant winter period to prevent nutrient burn.
Propagating Ruby Necklace
Propagating Othonna capensis is commonly done through stem cuttings. Select a healthy stem section and make a clean cut below a leaf node. Allow the cut end to “callous” or dry for a few days to prevent rot. Once calloused, place the cutting directly into well-draining succulent soil. Keep the soil barely moist until roots develop, then transition to a regular watering schedule.
Troubleshooting Common Issues
Leggy growth or a lack of vibrant color indicates insufficient light. Move the plant to a brighter location or provide supplemental grow lights to restore its compact form and rich hues. Mushy stems and leaves signal overwatering, which can lead to root rot. If this occurs, allow the soil to dry completely, and consider repotting into fresh, dry succulent mix after inspecting and trimming any rotted roots. Conversely, shriveling or dry leaves point to underwatering; a thorough soak will rehydrate the plant. Common succulent pests like mealybugs or scale insects can appear. Treat these by wiping them off with a cotton swab dipped in rubbing alcohol or by applying insecticidal soap or neem oil.
