Throwing out soil, to me, as an organic gardener…. makes as much sense as throwing out your oven after you used it once. That’s just me. 😀
Start with a 3 gallon grow. Broke it up and pulled all the excess roots out. I leave some roots in as it’ll just get composted in.
Add some Pro-Mix BX, Leaf Compost, worm castings, 2-4-3 chicken manure (has 8% calcium) and Azomite. In 3-4 weeks this will be ready to go. It could go now that leaf compost has enough nutes to grow in. It just gets better letting it process.
Cheap, easy way to add some fertility and reuse your old soil.
