Cotyledon gremlin is a captivating succulent, popular for its distinctive foliage. This plant offers unique charm to any collection.
Identifying Cotyledon Gremlin
Cotyledon gremlin is a succulent shrublet known for its trailing, branched stems that can reach up to 2 feet in length. Its teardrop-shaped leaves crowd the stems, creating a dense, textured look. Leaves are typically whitish-green with reddish margins and a powdery coating. As the stems mature, they can become woody and develop a brownish, peeling bark.
Flowers appear individually or in small clusters. These bell-shaped, orange-red flowers dangle from slender stalks during the summer months. Its specific epithet “pendens” refers to its hanging growth habit, ideal for hanging baskets or cascading over container edges.
Essential Care Requirements
Light
Cotyledon gremlin thrives in bright, indirect sunlight. While it can tolerate some direct sun, particularly in the morning, intense midday or afternoon sun can scorch its leaves. A south or west-facing window is ideal indoors. If natural light is limited, supplemental grow lights provide illumination. Insufficient light causes leggy growth.
Watering
Cotyledon gremlin prefers a “soak and dry” watering method; the soil should completely dry out between waterings. Drought-tolerant, it stores moisture in its fleshy leaves. Overwatering causes root rot, indicated by yellowing or rotting lower leaves and mushy stems. Shriveling or wilting leaves suggest thirst. Watering frequency should be reduced during the dormant winter months.
Soil and Potting
Well-draining soil is crucial for Cotyledon gremlin. A specialized succulent or cactus mix, with coarse sand or perlite, provides drainage and aeration. Standard potting soil retains too much moisture, increasing root rot risk. Pots with drainage holes are essential, and terracotta can enhance breathability. Repot every two to three years, or when roots become crowded, to ensure healthy growth.
Temperature and Humidity
Cotyledon gremlin prefers warm conditions, with an ideal temperature range between 65-75°F (18-24°C). It can tolerate cooler temperatures, especially if kept dry, but protection from frost is important as freezing temperatures can damage its leaves. Avoid prolonged exposure above 86°F (30°C), especially in summer. It thrives in low humidity (40-50%), as drier air helps prevent fungal issues.
Fertilization
Cotyledon gremlin does not require heavy or frequent fertilization. During its active growing season in spring and summer, a balanced, diluted liquid fertilizer formulated for succulents can be applied every four to six weeks. Diluting the fertilizer to half strength is beneficial. Stop fertilization in fall and winter when growth slows. Ensure the soil is moist before fertilizing to prevent root burn.
Propagation and Common Issues
Propagation Methods
Stem cuttings are an effective propagation method. Select a healthy stem and cut below a leaf node with clean, sharp shears. Allow the cut end to dry and form a callus (a few days to a week); this prevents rot when planted.
Once callused, insert the cutting into well-draining succulent soil, ensuring it stands upright. Water sparingly until roots develop. Leaf propagation is also possible.
Troubleshooting Common Problems
Overwatering frequently causes root rot. Symptoms include mushy stems and easily falling leaves. If root rot is suspected, unpot the plant, remove any rotting parts, allow the roots to dry, and repot in fresh, dry, well-draining soil.
Insufficient light causes etiolation, leading to leggy growth. Moving the plant to a brighter location helps, though stretched growth may not fully revert. Pest infestations, like mealybugs, can be treated with neem oil or insecticidal soap.
Leaf drop signals overwatering, underwatering, or too much intense direct sunlight. Shriveled, dry leaves indicate underwatering; soft, mushy leaves indicate overwatering. Proper watering and adequate light mitigate these issues.
