Soil-less Potting Medium


1 part coconut coir
1 part screened compost
1 part vermiculite or coarse builder’s sand
1 tsp lime or dolomite lime per gallon
½ c worm castings per gallon, or balanced fertiliser per recommended rates

Break up the fibres of the coconut coir and soak until hydrated.  Remove from water and mix soaked coir with vermiculite.  For seed-starting planting mixes, pass the compost through a ¼ inch screen; for transplants and established plants, use a ½ inch screen.  Add the remaining ingredients and mix thoroughly.  Prior to planting, wet the mixture until it feels like a damp, wrung-out sponge.
