FAQ's
How often should I water a cactus rock garden?
Cactus rock gardens typically need very little water, usually requiring irrigation only every 2-4 weeks during growing season and even less during winter. The specific watering schedule depends on your climate, soil type, and cactus species. Always ensure good drainage to prevent root rot.
What type of soil is best for a cactus rock garden?
Use a well-draining cactus soil mix combined with inorganic materials like pumice, perlite, or coarse sand. The ideal ratio is typically 50% organic cactus soil to 50% inorganic material. This ensures good drainage and prevents water-logging.
Can I mix different types of cacti in my rock garden?
Yes, you can mix different cacti species, but ensure they have similar water and sun requirements. Consider their mature sizes and growth rates when planning your layout. Some species may need more protection from winter weather than others.
What types of rocks work best in a cactus garden?
Use a variety of rocks including decomposed granite, river rocks, boulders, and decorative stones. Ensure rocks are placed securely and won't roll onto plants. Light-colored rocks reflect heat and can create micro-climates, while darker rocks absorb heat.
