Tips for Growing Barrel Cacti in Xeriscapes
- Plant in well-drained, sandy or gravelly soil to prevent root rot.
- Choose a sunny location with at least 6 hours of direct sunlight daily.
- Water sparingly, allowing the soil to dry out completely between watering sessions.
- Use cactus-specific or succulent fertilizers during the growing season.
- Protect young plants from extreme cold or frost, as many barrel cacti are sensitive to freezing temperatures.
