you can use just about anything, but there's a few guidelines to stick to.

Don't use miracle grow, or any other fertilizer infused soil, unless it's organic. Organic soils work really well.

make sure that the soil drains well - you may want to fill the bottom of the pot with sand or pebbles to help it.

don't use soil from outside off the ground - you never know what sorts of bugs you may be scooping up as well - spend a few bucks and buy a good bag of soil.

And if you can find something with worm castings, or bat guano in it, or anything along those lines - then you're really well set!
