How to Care for Cacti

1. Watering Tips

Proper watering is essential to avoid overwatering, which can lead to root rot.

2. Light Requirements

Cacti thrive in bright light, but the intensity depends on the species.

Indoor Care: Place near a south-facing window.
Outdoor Care: Gradually expose to direct sunlight to prevent burns.

3. Best Soil for Cacti

Cacti need well-draining soil to prevent waterlogged roots.

Use a commercial cactus mix or make your own with sand, perlite, and potting soil.
Avoid heavy, compacted soils.

4. Choosing the Right Pot

Drainage: Ensure your pot has drainage holes.
Material: Terracotta pots are ideal as they wick moisture away.
Size: Choose a pot slightly larger than the root ball.

5. Fertilizing Your Cactus

Use a balanced, low-nitrogen fertilizer during the growing season (spring and summer).
Avoid fertilizing during winter dormancy.

6. Temperature and Humidity

Cacti prefer dry air; avoid placing them in humid rooms like bathrooms.
