that's what I am thinking, plus we are putting 3.5CY of dirt on top of all that. I am buying visqueen rather than landscape fabric to line the edges. It will go about 6" over the top of the surrounding brick, then tuck in and over the cardboard for about 12". That should seal out any grass from the outside and also any grass on the edges of the inside. It should work. Will find out next summer. lol Thanks Caroline.
My peonies from Holland just arrived this morning about 10 minutes ago. yeah
