For the bed shown previously, I just left out the log separators in the lily area. By doing that, I'll still be able to dig and separate as necessary.
It's a really fun and rewarding process. I can say with quite a bit of confidence that I'll never plant directly into this ground again! Even my water-lovers get planting pockets now.
