I just use a pencil to poke a hole about 1/2" - 3/4" deep and drop the seed in...I know some people say to make sure the root is facing down but I don't and they seem to find their way. Then just press some dirt over it gently, give it an ounce or two of water and you're on your way.

I've killed off seedlings by overwatering too - now you know what not to do.
