Is there a good way to make homemade potting soil out of local soils that are heavily clay-dominant? Potting soils typically use perlite or vermiculite for drainage; could I sediment sand out of the soil, or would I be better off using crushed brick as larger aggregate?
Right now my model is 2 parts sedimented soil (silt + sand = maybe 10% of total makeup), 1 part biochar, 2 parts compost.
