🌱 How to Care for Mexican giant cardón to Prevent Botrytis?
💧 How to Water
Water sparingly: once per week in summer, every 12-20 days in spring and autumn, and suspend watering almost completely in winter. Always allow the soil to dry out fully between waterings. Never water the stem directly — water only at the base.
☀️ Lighting
Full sun is essential. Mature specimens require intense, direct sunlight year-round. Young plants can tolerate partial shade initially. When grown indoors, place near a south-facing window with maximum light exposure.
🪴 Ideal Soil
Use a fast-draining cactus mix with coarse sand, gravel, and perlite. Sandy soil with a pH between 6.0 and 8.0 is ideal. Ensure the pot or planting site has excellent drainage to prevent root rot.
