The right potting soil is the foundation of every healthy houseplant. Without a good mix, roots cannot breathe properly, water remains for too long, or your plant receives too little nutrition.

Why the right potting soil is so important
Good potting soil retains moisture without becoming saturated, allows air to reach the roots, and contains sufficient nutrients. The perfect balance consists of three components: moisture, air, and nutrition.
The 3 building blocks of good potting soil
- Drainage – prevents wet roots and root rot
- Aeration – allows roots to breathe
- Nutrition – gives your plant a good start
