🌱 How to Care for Chilean Cacti to Prevent Mealybugs?

💧 How to Water

In summer, water approximately every 10–14 days, only when the substrate is completely dry. In spring, every 2–3 weeks. In winter, stop watering completely or water at most once a month. Never let the roots sit in water—overwatering causes root rot, which can quickly destroy the entire plant.

☀️ Lighting

Eriosyce require full sun or very bright partial shade with at least 6 hours of direct sunlight per day. Indoors, place them as close as possible to a south-facing window. A lack of light causes etiolation (stretching) and prevents flowering.

🪴 Ideal Soil

Use a specialized cactus substrate containing at least 50–80% mineral components, such as coarse sand, gravel, or perlite. Top-dress the area around the root collar with gravel or coarse sand to prevent moisture buildup and fungal growth. Good drainage is an absolute necessity.
