🌱 How to Care for Spiral Cactus to Prevent Mealybugs?

💧 How to Water

Water sparingly and only when the substrate has completely dried out—typically once every 3 weeks during spring and summer. In winter, during the dormancy period, significantly reduce watering. Excess water combined with poor drainage is the most common cause of root rot.

☀️ Lighting

The plant loves intense, direct sunlight—adult specimens grow best with at least several hours of full sun per day. Young, recently rooted cuttings should be protected from the harshest midday sun to avoid sunburn.

🪴 Ideal Soil

Plant in a well-draining, sandy substrate designed for cacti and succulents. If you do not have a ready-made mix, you can combine universal potting soil with coarse sand or pumice in a 50/50 ratio to ensure rapid water drainage.
