Common Name: Copiapoa Cinerea
Family: Cactaceae
Origin: Native to the coastal deserts of Chile.
Description:
Copiapoa 'Cinerea' is a striking and visually appealing cactus known for its unique, globular form and silvery-gray coloration. This species typically grows to about 15-30 cm (6-12 inches) in height and can reach up to 20 cm (8 inches) in diameter. It features a ribbed surface with prominent tubercles and short, spiny areoles, giving it a distinctive texture. In late spring and summer, 'Cinerea' produces beautiful, funnel-shaped flowers that can be yellow or pale orange, blooming from the crown of the cactus.
Light Requirements:
- Sunlight: Prefers bright, direct sunlight for several hours each day. A south or west-facing window is ideal.
- Avoid: Prolonged periods of deep shade, which can lead to etiolation and weaken the plant.
Watering:
- Frequency: Water thoroughly during the growing season (spring and summer) when the top inch of soil is dry. In fall and winter, reduce watering significantly, allowing the plant to enter dormancy.
- Method: Water deeply at the base, allowing excess water to drain out. Avoid letting the cactus sit in water to prevent root rot.
Soil:
- Type: Use a well-draining cactus mix or create your own by mixing potting soil with sand, perlite, or pumice.
- pH: Slightly acidic to neutral (around 6.0 to 7.0).
Temperature and Humidity:
- Temperature: Thrives in warm conditions between 20-30°C (68-86°F). Protect from frost and extreme cold.
- Humidity: Prefers low humidity; avoid high humidity environments to reduce the risk of rot and fungal issues.
Fertilization:
- Frequency: Fertilize during the growing season with a diluted cactus fertilizer once a month. Do not fertilize during winter dormancy.
- Type: Use a balanced, water-soluble fertilizer formulated for cacti.
Repotting:
- When: Repot every 2-3 years or when the cactus outgrows its container.
- Method: Carefully remove the cactus from its pot, ensuring minimal disturbance to the roots, and replace with fresh, well-draining soil.
Pests and Problems:
- Common Pests: Watch for mealybugs, spider mites, and scale. Treat infestations promptly with insecticidal soap or neem oil.
- Rot: Overwatering can lead to root rot. Ensure proper drainage and allow the soil to dry out thoroughly between waterings.
Additional Tips:
- Propagation: Copiapoa 'Cinerea' can be propagated from seeds or offsets. Seeds should be sown in a well-draining medium and kept warm and moist until germination.
- Display: Ideal for container gardens, rock gardens, or as a unique specimen in a succulent collection. Its striking appearance and beautiful blooms make it a standout addition.
With the right care, Copiapoa 'Cinerea' can thrive and bring a touch of elegance to your cactus collection!
