Ideal Ratio (General Guide)
-
60% Potting Soil
-
20% Lava Rock
-
20% Pine Bark
You can adjust the mix depending on the plant type:
-
For succulents or cacti: Increase lava rock (30-40%) for faster drainage.
-
For orchids or aroids: Increase pine bark (40-50%) for airier structure.
-
For general houseplants: Use the suggested 60/20/20 mix.
Key Notes:
-
Ensure lava rocks are not too large; medium to small sizes work best for root contact.
-
Pine bark should be aged or composted, not fresh, to avoid nitrogen lock.
-
This mix is excellent to prevent root rot and helps oxygen reach the roots effectively.
