1 T Beneficial Bacteria (Root Zone)

Mix together well.

1 part fine soilless mix (above mix or commercial)

1 part vermiculite

Mix together well.

 

Basic Container Mix

1 part horticulture vermiculite or perlite

1 part peat moss or coconut coir

1 part compost or worm compost

Soil straight from the garden shouldn't be used for potting mixes.  Even the best garden loams compact too quickly in containers and could possibly contain disease.
