Worm castings

[Redeyedfrog]

I think the biggest advantages are its very high quality, it's totally organic and it only cost scraps and lawn clippings, and it's nearly impossible to burn your plants and I never run out of the stuff, win win win!

Just to clarify, worm castings are the solids produced by worms; worm wee is the liquid used as a fertiliser. Both are excellent, though have different uses. The castings are excellent in soil mixes, for adding structure and beneficial microorganisms. And the liquid makes a fine fertiliser (and again is living, therefore adding beneficial microorganisms to the rootzone when used).
