Sedum nussbaumerianum, commonly known as Coppertone Stonecrop, is a popular succulent cherished for its distinctive foliage. This plant features thick, pointed leaves that shift from yellow-green to a striking coppery-orange, especially when exposed to ample sunlight. Its low-maintenance nature makes it a favored choice for both novice and experienced plant enthusiasts. This evergreen perennial adds vibrant color and texture to any collection.
Essential Care Requirements
Light
Coppertone Stonecrop thrives in bright, direct sunlight, requiring at least six hours daily for growth and coloration. Intense light enhances its signature coppery-orange hue. Insufficient light can cause the plant to stretch, a process known as etiolation, resulting in a leggy appearance and duller leaf color. In extremely hot climates, providing some afternoon shade can prevent leaf scorching.
Watering
The “soak and dry” method is recommended for watering Sedum nussbaumerianum. Water thoroughly until excess drains from the bottom of the pot, then allow the soil to dry completely before the next watering. Overwatering is a common issue for succulents and can lead to root rot. Watering frequency varies with season and climate, more often in warmer months and less during cooler periods.
Soil
Well-draining soil is important for Sedum nussbaumerianum. A commercial succulent or cactus mix provides the necessary drainage to prevent waterlogging. Alternatively, a custom blend can be created using potting soil, perlite, and coarse sand. Adequate drainage prevents water from accumulating around the roots, helping to avert root rot.
Temperature
Coppertone Stonecrop prefers warm temperatures, ranging between 60-80°F (15-27°C). It is suitable for outdoor cultivation in USDA Zones 10-11, where it can tolerate mild frost for short durations. In colder regions, grow this succulent in containers so it can be moved indoors when temperatures drop below 50°F (10°C) to protect it from freezing conditions.
Fertilizing
Sedum nussbaumerianum is not a heavy feeder and does not require extensive fertilization. If desired, a diluted, balanced liquid fertilizer can be applied once or twice during its active growing season in spring and summer. A quarter-strength solution is sufficient to provide a mild nutrient boost without over-fertilizing. Avoid fertilizing during the dormant winter months.
Potting and Repotting
Repotting Sedum nussbaumerianum is needed when the plant becomes root-bound or every one to two years to refresh the soil. Choose a pot with drainage holes to ensure excess water can escape. When repotting, carefully remove the plant from its current container and gently shake off old soil from the roots. Inspect the roots for any signs of damage or rot before placing the plant in a slightly larger pot filled with fresh succulent mix.
Propagation
Sedum nussbaumerianum is straightforward to propagate, with stem and leaf cuttings being effective methods. For stem cuttings, select a healthy stem, cut a section a few inches long, and allow the cut end to dry and form a callus for a couple of days. Once callused, plant the cutting in well-draining soil. Leaf cuttings involve gently twisting a healthy leaf from the stem, allowing it to callus, then placing it on top of or slightly pressed into the soil. Roots begin to form within a few weeks, leading to new plant growth.
Common Issues and Solutions
Several common issues can affect Sedum nussbaumerianum. Etiolation, characterized by stretched or leggy growth, occurs when the plant does not receive enough light. Moving the plant to a brighter location with more direct sunlight will encourage more compact growth and vibrant coloring.
Root rot is a problem caused by overwatering or poorly draining soil. Adjusting watering habits to allow the soil to dry completely between waterings and ensuring the plant is in a well-draining mix can resolve this issue. If root rot is severe, repotting into fresh, dry soil after trimming affected roots may be necessary.
Pests such as mealybugs and aphids can infest Coppertone Stonecrop. These can be managed by gently wiping them off with a cotton swab dipped in rubbing alcohol or by applying an insecticidal soap solution. Dull coloration in leaves indicates insufficient light, which can be corrected by increasing the plant’s exposure to direct sunlight.
