Hmmm, it says natural on the package but didn't see organic. Still do not see a reason you can't use it. As far as worm poop goes I mix worm castings in with my pro-mix.
anyone know if i can use this "worm poop" fertilizer (2-1-1)
Worm castings are worm poop, if you look closely at the first pic you can read what this stuff is derived from. Natural and organic are not the same, worm castings organic, this stuff not so sure, but doesn't matter to some people.
