I was initially put off the idea of making a lasagna bed because I thought I'd have to look at a expanse of mulch with nothing in it for an extended period of time. So, when I finally made one under the white birch I left spaces for a few holly shrubs, which I added right away, and then I added sunken pots of annuals while I waited for the materials to break down. This satisfied my "want-it-now" sense of visual appeal.
