Arranging cacti in an outdoor plant box can transform your space into a striking desert-inspired oasis. Here’s the best way to do it:

1. Choose the Right Plant Box: Opt for a shallow, wide container with drainage holes to prevent waterlogging. Terracotta or concrete boxes work well for cacti.

2. Select Complementary Varieties: Mix tall, columnar cacti (like saguaro or organ pipe) with shorter, round varieties (such as barrel or hedgehog cacti) for visual interest.

3. Mind the Spacing: Leave enough room between plants to account for growth—typically 6–12 inches apart, depending on the species.

4. Use Well-Draining Soil: Fill the box with a cactus-specific potting mix or amend regular soil with sand and perlite for better drainage.

5. Add Decorative Touches: Scatter small rocks or gravel around the cacti to mimic a natural desert landscape and reduce weed growth.

6. Position for Sunlight: Place the plant box in a sunny spot where the cacti will receive at least 6 hours of direct sunlight daily.

With these tips, your outdoor cactus arrangement will thrive and become a eye-catching focal point in your garden!
