Re: How to amend your soil

RE:
1 - 5 gallon already used soil
1 - 5 gallon of Sphagnum Peat Moss
1 - 5 gallon of Perlite
1 gallon of Worm Castings
1 cup of Azomite

should work. My basic potting soil recipe is something organic like compost, something fluffy like peat moss or coconut coir, something loose and free draining like perlite or rice hulls in roughly equal amounts. You basically have that, except that your 5 gall of already used soil has had a lot of the nutrients and texture depleted out of it. You are making up for the nutrients with the worm castings and azomite. What is left is texture. As has been mentioned, the used potting soil gets kind of broken down in to smaller particles which can compact. The azomite and worm castings are both also very fine textured. You could make up for that by increasing the proportion of perlite or adding in something else with a coarser texture, maybe some coarse sand or a bit of shredded bark.
