Crassula rupestris 'High Voltage' is a unique cultivar known for its striking appearance and growth habits. Here's a care sheet tailored specifically for Crassula rupestris 'High Voltage':
Light: Crassula rupestris 'High Voltage' thrives in bright, indirect light. It can tolerate some morning sun or filtered light, especially in cooler climates. However, protect it from intense, direct sunlight to prevent leaf burn, particularly during the hottest part of the day.
Watering: Water 'High Voltage' moderately, allowing the soil to dry out partially between waterings. During the growing season (spring and summer), water when the top inch (2.5 cm) of soil feels dry. Reduce watering in winter when growth slows down, watering only when the soil is mostly dry.
Soil: Plant Crassula rupestris 'High Voltage' in a well-draining succulent or cactus mix. A sandy or gritty soil with excellent drainage is essential to prevent waterlogging, which can lead to root rot. Ensure the pot has adequate drainage holes.
Temperature: Maintain moderate temperatures for 'High Voltage' between 65-75°F (18-24°C) during the active growing season. It can tolerate slightly higher temperatures but should be protected from extreme heat and frost as it is not frost-tolerant.
Humidity: Average indoor humidity is generally suitable for Crassula rupestris 'High Voltage'. It does not require high humidity levels and can tolerate dry air typical of indoor environments.
Fertilizing: Feed 'High Voltage' sparingly with a balanced, diluted fertilizer formulated for succulents once a month during the growing season (spring and summer). Refrain from fertilizing during fall and winter when the plant's growth slows down.
Propagation: Propagate Crassula rupestris 'High Voltage' from stem cuttings. Allow the cuttings to callus for a few days before planting them in well-draining soil. Keep the soil lightly moist until roots develop. Leaf cuttings can also be propagated similarly.
Pruning: Prune 'High Voltage' to maintain its compact and attractive growth habit. Trim any leggy or dead stems as needed to encourage bushier growth and maintain the plant's shape.
Pests and Problems: Monitor for common succulent pests such as mealybugs or spider mites. Treat infestations promptly with insecticidal soap or neem oil. Ensure good air circulation around the plant to prevent fungal issues.
Potting and Repotting: Repot Crassula rupestris 'High Voltage' every 2-3 years or when it outgrows its current container. Choose a slightly larger pot with drainage holes to accommodate the plant's root system.
Special Care Notes:
Crassula rupestris 'High Voltage' is relatively low-maintenance but benefits from regular monitoring of watering and light conditions.
Avoid overwatering to prevent root rot, especially during the dormant winter period.
Provide bright light and occasional direct sun exposure to maintain its vibrant coloring and growth pattern.
By following these care guidelines, you can help your Crassula rupestris 'High Voltage' thrive and display its unique and attractive characteristics in your succulent collection, whether indoors or outdoors.
