ðą How to Care for Hedgehog Cactus to Prevent Spider Mites?
ð§ 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 â when in doubt, do not water.
âïļ Lighting
Requires full direct sun â 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.
ðŠī 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 6.0â7.5 is ideal. Good drainage is more important than soil richness.
