Crassula mesembryanthemoides ‘Tenelli’ is a distinct succulent with fuzzy, cylindrical leaves tightly packed along its stems. Fine hairs give the leaves a soft, velvety texture.
In late winter to early spring, it produces small, daisy-like white flowers from its leaf axils. Its compact, mounded form makes it suitable for various indoor and outdoor settings.
Growing Conditions and Care
Crassula mesembryanthemoides ‘Tenelli’ thrives in bright, indirect sunlight for compact growth and vibrant color. It tolerates some direct morning sun, but harsh afternoon sun can cause scorching. Insufficient light leads to etiolation, where stems become leggy.
Overwatering is common for this drought-tolerant succulent. Use the “soak and dry” method: water thoroughly until it drains, then allow the soil to dry completely. Check soil moisture or pot weight to determine watering needs. Excess moisture causes root rot, leading to mushy stems and leaves.
Water requirements decrease during cooler months or dormancy. Reduce watering in autumn and winter to prevent rot from cold, damp soil. Adjust the watering schedule based on the plant’s response.
Well-draining soil is essential. Use a specialized succulent or cactus mix for aeration and drainage. Amend with perlite, pumice, or coarse sand to enhance drainage, preventing waterlogging and fungal issues, and maintaining a healthy root environment.
Maintain temperatures between 65-80°F (18-27°C). Protect from frost; below 40°F (4°C) can cause damage. High humidity is not needed; excessive humidity can lead to fungal problems, so ensure good ventilation.
Fertilize minimally, if at all. If needed, apply a diluted succulent-specific fertilizer once or twice during its active growing season (spring or early summer). Avoid fertilizing during dormancy, as this can cause nutrient burn and stress. Over-fertilization harms the root system.
When potting, choose a container with drainage holes. Terracotta pots are preferred as they help soil dry faster than plastic. Select a pot not overly large for the root ball to prevent excess moisture.
Propagation
Propagate using stem cuttings. Select a healthy stem section with a few leaves and make a clean cut with sterilized shears or a knife. Cuttings should be about 3-4 inches (7-10 cm) long.
After taking the cutting, allow the end to callus for several days to a week in a dry, well-ventilated area away from direct sunlight. This step allows the wound to heal, preventing rot. Once callused, the cutting is ready for planting.
Insert the callused end into a well-draining succulent or cactus potting mix. Do not water immediately; wait a few days before lightly moistening the soil. Place the cutting in a warm spot with bright, indirect light to encourage root development, which usually takes weeks. Water sparsely, only after the soil has dried, to support rooting.
Common Issues and Troubleshooting
Overwatering is a common problem, with symptoms like mushy, translucent leaves and soft, decaying stems, indicating root or stem rot. If these signs appear, stop watering and let the soil dry completely. For severe cases, repot into fresh, dry soil after trimming any rotted sections.
Underwatering is less harmful than overwatering. Symptoms include shriveled, wrinkled, or crispy leaves. To rehydrate, water thoroughly until the soil is saturated and drains. Leaves should plump up within a day or two.
Insufficient light causes etiolation: leggy, stretched stems with widely spaced leaves. This happens as the plant stretches for light, leading to a weakened, elongated appearance. Move the plant to a brighter location with indirect sunlight; pruning stretched growth encourages a more compact, bushier form.
Pests like mealybugs and spider mites can affect Crassula mesembryanthemoides ‘Tenelli’, though severe problems are uncommon. Mealybugs appear as small, white, cottony masses in leaf axils; spider mites create fine webbing and tiny leaf spots. Remove mealybugs with diluted rubbing alcohol on a cotton swab; manage spider mites with insecticidal soap sprays.
