The Pedilanthus plant, known as “Devil’s Backbone” or “Slipper Flower,” is a distinctive succulent with unique zigzag stems. This intriguing houseplant adds an architectural element to any space. Its low maintenance requirements make it a popular choice for plant enthusiasts.
Pedilanthus Essential Care
Light Needs
Pedilanthus thrives in bright, indirect light conditions. Placing it near a window that receives morning or evening sunlight is ideal. While it can tolerate some direct sun, harsh afternoon rays can lead to scorched or crispy leaves, indicating too much light exposure. Insufficient light, however, may cause the plant to become leggy and lose its vibrant coloration.
Watering Schedule
As a succulent, Pedilanthus prefers its soil to dry out between waterings. Overwatering can lead to root rot. Check soil moisture by inserting a finger two inches deep; water if dry. Reduce watering frequency during cooler fall and winter months, allowing the soil to dry more thoroughly.
Soil Requirements
A well-draining soil mix is crucial for the Pedilanthus to prevent waterlogging and promote healthy root development. A cactus or succulent potting mix is often recommended, as it provides the necessary drainage. Enhancing the soil with amendments such as perlite, pumice, or coarse sand can further improve aeration and drainage.
Temperature and Humidity
Pedilanthus prefers warm temperatures, ideally 65-80°F (18-27°C) during the day. It is sensitive to cold drafts and temperatures below 50°F (10°C), which can damage the plant. Average household humidity is sufficient, though higher humidity is beneficial in dry environments.
Fertilizing
During its active growing season in spring and summer, Pedilanthus benefits from a monthly application of a balanced liquid fertilizer. Dilute this fertilizer to half the manufacturer’s recommended strength to avoid over-fertilization. Withhold fertilizing entirely during the fall and winter months.
Maintaining Your Pedilanthus
Pruning for Shape
Pruning Pedilanthus helps maintain its desired shape and encourages bushier growth, preventing legginess. Remove any problem branches or stems, and perform a light trim in late winter. Use clean, sharp pruning tools for precise cuts.
Repotting Your Plant
Repotting is generally needed every two to three years, or when the plant becomes root-bound. Select a container only slightly larger than the previous one, ensuring adequate drainage holes. Use fresh, well-draining succulent potting mix to revitalize the plant.
Common Problems
Leaf drop can occur due to environmental stress, such as sudden changes in temperature or light, or improper watering. Leggy growth, characterized by elongated stems with sparse leaves, indicates insufficient light. While generally resilient, Pedilanthus can be susceptible to common houseplant pests like spider mites and mealybugs, managed with insecticidal soaps or neem oil.
Propagating Pedilanthus
Propagating Pedilanthus is straightforward, primarily through stem cuttings. The best time to take cuttings is during spring or early summer when the plant is actively growing. Select a healthy stem section, typically 4 to 6 inches long, ensuring it has a few leaves.
After taking the cutting, allow the cut end to callus or dry for a few days; this prevents rotting. Once callused, insert the cutting into a pot filled with a well-draining medium like perlite or sandy potting mix. Maintain slight moisture until roots develop, which usually takes a few weeks.
Safety Precautions
Pedilanthus, like many Euphorbiaceae plants, produces a milky white sap when its stems are cut or damaged. This sap contains compounds irritating to the skin and eyes, potentially causing redness, inflammation, or blistering.
Wear gloves and eye protection when handling or pruning the plant to minimize sap exposure. If skin contact occurs, wash the affected area thoroughly with soap and water. For eye contact, immediately flush with clean water and seek medical attention. The sap is toxic if ingested, so keep the plant out of reach of pets and children.
