Cotyledon pendens, often known as the “Cliff Cotyledon” or “String of Rubies,” is a captivating succulent that has garnered popularity among plant enthusiasts for its unique trailing growth and striking foliage. Native to Madagascar, this plant grows in conditions that mimic its natural habitat. In this comprehensive guide, we will explore the essential aspects of Cotyledon pendens care, ensuring your plant remains healthy and vibrant.
Understanding Cotyledon Pendens
Before diving into the care specifics, it’s essential to understand the characteristics of Cotyledon pendens. This succulent is known for its trailing stems, which can reach up to three feet in length. The leaves are fleshy, cylindrical, and typically a vibrant green, turning reddish-purple when exposed to full sun. During the blooming season, it produces charming bell-shaped flowers, adding to its ornamental appeal.
Light Requirements
Cotyledon pendens thrives in bright, indirect light. It can tolerate direct sunlight, especially during the morning hours, but prolonged exposure to intense afternoon sun can cause the leaves to scorch. If you’re growing this plant indoors, placing it near a south or east-facing window is ideal. For outdoor cultivation, a spot with filtered sunlight or partial shade works best.
Watering Routine
As with most succulents, Cotyledon pendens prefers a “soak and dry” watering method. This means you should water the plant thoroughly until water drains from the bottom of the pot, then allow the soil to dry out completely before watering again. Overwatering can cause root rot, which is a common problem for succulents. You may need to water more often during the growing season (spring and summer) and reduce the frequency during the dormant period (fall and winter).
Soil and Potting Mix
Cotyledon pendens requires well-draining soil to prevent water retention, which can lead to root rot. A cactus or succulent potting mix works well, or you can create your own by combining regular potting soil with coarse sand and perlite. The pot should have drainage holes to ensure excess water can escape, keeping the roots dry and healthy.
Temperature and Humidity
Cotyledon pendens is quite adaptable to a range of temperatures but prefers a warm environment. It thrives in temperatures between 65°F to 80°F (18°C to 27°C). While it can tolerate cooler temperatures down to 40°F (4°C), it should be protected from frost. Humidity levels are not a significant concern for this succulent, as it is naturally adapted to arid conditions. However, ensure good air circulation to prevent any potential fungal issues.
Fertilization
Fertilizing Cotyledon pendens is not a strict requirement, but it can promote healthy growth and vibrant foliage. Use a balanced, water-soluble fertilizer diluted to half strength once a month during the growing season. Avoid over-fertilizing, as this can lead to nutrient burn and negatively impact the plant’s health. During the dormant season, refrain from fertilizing as the plant’s growth slows down.
Pruning and Maintenance
Regular pruning helps maintain the shape and health of Cotyledon pendens. Trim any dead or damaged leaves and stems to encourage new growth. If the plant becomes too leggy or overgrown, you can trim back the stems to promote a more compact and bushy appearance. Use clean, sharp scissors or pruning shears to make precise cuts and minimize damage to the plant.
Propagation
Cotyledon pendens can be easily propagated through stem cuttings. To propagate, follow these steps:
Select a Healthy Stem: Choose a healthy stem with several leaves.
Cut the Stem: Use a clean, sharp knife or scissors to cut a section of the stem, ideally 4-6 inches long.
Allow to Callous: Place the cutting in a dry, shaded area for a few days to allow the cut end to callous over.
Plant the Cutting: Once the cut end has calloused, plant it in well-draining soil. Water sparingly until roots develop, then follow the regular care routine.

Common Problems and Solutions
Despite being relatively low-maintenance, Cotyledon pendens can face some common issues:
Overwatering: Symptoms include yellowing leaves and a mushy stem. Ensure proper watering practices and check that the soil drains well.
Underwatering: The plant may show signs of dehydration, such as wrinkled leaves. Modify your watering routine to ensure the plant gets sufficient moisture.
Pests: Common pests include mealybugs and aphids. Address infestations by using insecticidal soap or neem oil, and isolate the affected plant to prevent the spread.
