How to Grow

Choosing a Location 🌞

To ensure your Mezcala Old Man Cactus thrives, select a spot that receives full sun exposure for at least 6-8 hours daily. This cactus loves warmth, so aim for temperatures between 20°C to 30°C (68°F to 86°F) for optimal growth.

Soil Preparation 🌱

The right soil is crucial for your cactus's health. Use well-draining soil to prevent root rot, and maintain a pH level between 6.0 to 7.5 for the best results.

Planting Techniques 🌵

When planting, dig a hole that is 2-3 inches deep. Space your cacti 12-18 inches apart to allow for proper air circulation and growth.
