🌱 How to Care for Chichipe Cactus to Prevent Stem Necrosis?

💧 How to Water

Use the "soak and dry" technique: water deeply every 14-21 days in spring and summer, ensuring the substrate is completely dry before watering again. In autumn, gradually reduce the frequency; in winter, almost completely suspend watering (at most once a month). Always prevent water from stagnating at the base or in the saucer.

☀️ Lighting

Needs at least 5-6 hours of direct sun daily for optimal growth. Place it in the brightest spot available: outdoors in full exposure or a south-facing window with maximum light entry. Lack of light causes etiolation (weak, pale elongation). Indoors, it may require supplemental lighting.

🪴 Ideal Soil

Use a very well-draining substrate: mix 50% cactus soil with 50% gravel, coarse sand, or perlite. Add volcanic rock or pumice to improve root aeration. The ideal pH is between 6.0 and 7.5. Ensure the pot has large drainage holes to prevent moisture buildup.
