develop a green thumb

So some of the herbs have died, but the huge basil pot is doing great. Where can I get good organic potting soil here? I want to go someplace besides Home Depot.

I can’t wait to set up pots and pots of herbs on our front balcony. Every time I buy fresh basil I get annoyed, because it’s so great growing it. My last apartment wouldn’t work for growing things, though, so it’s been a while for me. After mastering herbs first, maybe I can move on to veggies. Is there enough room out there?
