Beginner Cactus Care in Perth, Australia: Water, Light, and Soil Basics

Core Principles

• Soil: Fast-draining mix (50% potting soil + 50% coarse sand/pumice/perlite).
• Pot: Terra cotta with drainage hole; no saucer holding water.
• Light: Brightest possible indirect light indoors; morning sun outdoors after acclimation.
• Water: Only when soil is completely dry. In Perth's Mediterranean climate: ~every 2–3 weeks summer, monthly winter.

Identifying Your Cactus

Care varies by species. Desert globulars (e.g., Echinocactus) need less water than jungle cacti (e.g., Schlumbergera). If unsure, post a photo to a cactus forum or local nursery for ID.

Common Beginner Mistakes

1. Overwatering (the #1 killer).
2. No drainage holes.
3. Peat-heavy soil that stays wet.
4. Direct sun on unacclimated plants.

Golden rule: When in doubt, don't water. Cacti survive drought far better than soggy roots.
