🌱 How to Care for Leaf Cactus to Prevent Mealybugs?

💧 How to Water

Water when the top two to three centimeters of soil have dried out, keeping the substrate lightly moist through the growing season and cutting back in cooler months; unlike desert cacti, Leuenbergeria can suffer from underwatering as much as from soggy roots.

☀️ Lighting

Provide several hours of bright, indirect or filtered light daily; a spot with morning sun and afternoon shade works well, since intense all-day direct sun can scorch the leaves in dry climates.

🪴 Ideal Soil

Use a loamy, well-draining potting mix enriched with organic matter, similar to a general tropical-plant blend rather than a lean cactus mix, and keep the pH close to neutral, around 6 to 7.5.
