Thanks, Zig. I was very pleased to get that 'Cups' at out local Farmers' Market for $3. Score! It's in the ground now and I'm anxious to see it again this year soon. Love those EEs! I image you have a lot of them.
Alas, Bermuda grass has underground runners, runners on top of the ground, and it seeds like crazy. It's one determined-to-survive grass! And it is not so easy to pull out and impossible when the ground is dry. It also forms a solid mat that is just about impossible for anything to grow through or penetrate. Sometimes you have to take desperate measures and flat, dull cardboard is the lesser of all the evils, I think.
I agree wholeheartedly about the weeds. They aren't so bad once you come to terms with them.
