Crassula ovata 'Gollum', commonly known as "Shrek's ears":
Light: Crassula ovata 'Gollum' prefers bright, indirect light. It can tolerate some direct sunlight, especially in the morning or late afternoon, but intense afternoon sun can scorch its leaves.
Watering: Water thoroughly but allow the soil to dry out between waterings. These plants are drought-tolerant and can handle periods of dryness better than overwatering. During winter, reduce watering frequency as the plant's growth slows down.
Soil: Use a well-draining cactus or succulent potting mix. Adding perlite or coarse sand can improve drainage. Avoid heavy, water-retentive soils that can lead to root rot.
Temperature and Humidity: Crassula ovata 'Gollum' prefers average room temperatures between 65-75°F (18-24°C). It can tolerate slightly cooler temperatures in winter but protect from frost and freezing temperatures. Average indoor humidity is usually sufficient.
Fertilizing: Feed with a balanced, diluted liquid fertilizer during the growing season (spring and summer) about once a month. Reduce or stop feeding during fall and winter when growth slows down.
Propagation: Propagate from stem or leaf cuttings. Allow cuttings to callus for a few days before placing them in a well-draining succulent mix. Keep the soil lightly moist until roots develop.
Pruning: Trim leggy growth to encourage a more compact shape. Pinch or prune stems to promote branching and denser growth.
Pests and Problems: Watch for common succulent pests like mealybugs or spider mites. Treat infestations promptly with insecticidal soap or alcohol wipes. Ensure good air circulation around the plant to prevent fungal issues.
Potting and Repotting: Repot every 2-3 years or when the plant outgrows its container. Choose a slightly larger pot with drainage holes to accommodate root growth.
Special Care Notes:
Crassula ovata 'Gollum' is susceptible to overwatering, which can lead to root rot. Always err on the side of underwatering rather than overwatering.
The unique tubular leaves of 'Gollum' may collect dust or debris. Gently wipe the leaves with a soft cloth or brush to keep them clean and healthy.
By following these care guidelines, you can help your Crassula ovata 'Gollum' thrive and maintain its unique appearance.
