Boy PJ, you have been busy.  I used the Victorian trench idea (although I didn't know it had a name) in one of the beds out front.  The grass around it is mostly weeds and Buffalo grass so it works perfectly, nothing aggressive like Bermuda grass. I do have to clean up the edge several times a season, you all know I'm excessive in neatness...no weeds or grass in my beds! I know, it's a sickness.

You guys have all been so busy.  You all will be ready to sit back and enjoy all the bounty of the seasons.
