🌱 How to Care for Hedgehog Cactus to Prevent Spider Mites?

💧 How to Water

Water every 14 days in spring and summer, allowing soil to dry completely between waterings. In winter, reduce to once a month or stop entirely. Overwatering is the number one cause of death — when in doubt, do not water.

☀️ Lighting

Requires full direct sun — at least 6 hours per day. Outdoors, choose the sunniest spot available. Indoors, place within 12 inches of a south-facing window. Insufficient light leads to etiolation and failure to bloom.

🪴 Ideal Soil

Use a well-draining cactus mix with added coarse sand or perlite (50/50 ratio recommended). Avoid heavy clay-based soils. A slightly acidic to neutral pH of 6.0–7.5 is ideal. Good drainage is more important than soil richness.
