Can one of you tell me what I should plant these things in, as far as dirt is concerned? I have 6 or 8 of those bricks with the holes in them, and I thought that would be a good edge for a bed. I just don't know what to put in the holes. I've got some very small gravel/grit, and I'm sure that would be a good place to start, but there is no dirt in it to speak of. The only other thing I have on hand is compost and Miracle Grow garden soil. I am not sure that either of those would be a good choice. Not sure of the dirt to grit ratio, either. This is a whole new world for me! I can easily dig some dirt up, which would be plain old dirt, with nothing added, so hopefully that will work, but I need suggestions!
