I use that on some of my veggies, I like it.I bought liquid worm poop from home Depot, It's been working pretty well... I used too much once and they got fertilizer burned... the bottle claims its like 99% worm poop.
if you searched worms, i think you'll find it was suggested NOT to put live worms in your pots. they'll most likely die. and it's no problem if they do, they're 90% water. but they'd be better off alive in your compost pile.you should put live worms in... search worms on this site. but if there dead I guess do that I don't see how it could be bad.
