Add a layer of gravel or coffee filters to prevent soil loss
Best Soil Mix for Containers
Never use regular garden soil it’s too heavy and poorly drained for pots.
Recommended Mix:
Potting Mix (base layer)
Compost or Worm Castings (nutrients)
Perlite or Pumice (aeration)
Optional: Coconut Coir for water retention in hot climates
✅ Pro Tip: Mix fresh compost into your containers every 4–6 weeks to refresh nutrients.
