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.
