I like the idea of using bags of leaves as insulation!
I seem to have some kind of drainage fetish and I'd find a low, boggy spot a continual challenge. But if you have a big enough space that you don't need to use every square foot for beds, maybe having the variety is a good thing.
My very first drainage project ever reminded me that (as we all know, even me), water runs downhill. However (which I had forgotten), then it STAYS right there unless you give it an exit path to an even lower spot.
P.S. That bag of "Soil Pep" is the worst soil conditioner I ever bought, made or imagined. It was mostly coarse wood chips, and created an ugly solid mass of fungus when I buried too much in one bed. The nitrogen deficit probably contributed to nothing growing well that year in that bed. It is, at best, an adequate mulch.
