After a fair amount of online research, I settled on the following potting soil recipe. Having repotted many of my 50 typical houseplants, I am having trouble with water running straight through the pots. I pretty sure it is not because of over-dry or over-wet soil. Do you see anything wrong with the following recipe for typical houseplants?
2 parts sterilized compost 2 parts coconut coir 1 part worm castings 1 part perlite 1 part vermiculite 1 part sand
