Corpuscularia lehmannii Care Sheet
Common Names:
Ice Plant, Ice Plant Succulent
Scientific Name:
Corpuscularia lehmannii
Description:
Corpuscularia lehmannii, commonly known as Ice Plant, is a low-growing succulent with thick, triangular leaves that are densely packed along trailing stems. The leaves have a powdery, icy-blue coating (farina) that gives the plant its distinctive appearance. It produces small, star-shaped yellow flowers in late winter to early spring.
Light Requirements:
Indoors: Prefers bright, indirect light. A south or east-facing window is ideal. It can tolerate some direct sunlight, especially in the morning or late afternoon.
Outdoors: Thrives in full sun to partial shade. In hot climates, provide afternoon shade to protect from intense sunlight.
Temperature:
Ideal Range: 65-75°F (18-24°C)
Tolerance: Can tolerate temperatures down to 40°F (4°C) but should be protected from frost and freezing temperatures.
Indoors: Keep away from cold drafts and sudden temperature fluctuations.
Watering:
Frequency: Water sparingly but deeply during the growing season (spring and summer), allowing the soil to dry out completely between waterings.
Method: Water the soil directly and avoid wetting the leaves excessively to prevent rot. Reduce watering in winter when growth slows.
Humidity:
Prefers low humidity levels. Good air circulation is beneficial to prevent fungal issues, especially in humid climates.
Soil:
Type: Well-draining cactus or succulent mix.
DIY Mix: Combine regular potting soil with sand, perlite, or pumice in a 2:1 ratio to improve drainage and aeration.
Fertilizing:
Frequency: Fertilize sparingly during the growing season with a balanced, water-soluble fertilizer diluted to half strength, about once every 4-6 weeks.
Type: Avoid fertilizing in winter when the plant is dormant or growing slowly.
Potting and Repotting:
Container: Use a pot with drainage holes to prevent waterlogged soil.
Repotting: Repot every 2-3 years or when the plant outgrows its container. Spring is the best time for repotting to encourage new growth.
Pruning and Maintenance:
Pruning: Minimal pruning is needed. Remove any dead or damaged leaves as necessary to maintain plant health and appearance.
Propagation: Easily propagated from stem cuttings. Allow cut ends to callous for a few days before planting in well-draining soil.
Pests and Problems:
Common Pests: Watch for mealybugs and aphids. Treat infestations promptly with insecticidal soap or neem oil.
Issues: Overwatering can lead to root rot and fungal diseases. Ensure proper watering practices and good air circulation to prevent problems.
Tips for Success:
Handle the plant carefully to avoid damaging the delicate leaves and powdery coating.
Rotate the plant occasionally to promote even growth and prevent legginess.
Protect from extreme temperatures and sudden changes in environmental conditions.
