I think this is a wondrful idea but I wish I had known about it earlier in life.
I do the Ruth Stout method and it is great for those of us in our senior years. You just can't beat it if you have access to old hay. Just throw it on the ground in fall, pull aside and plant in spring. Add a Little more around plants. No weeding, no or very little watering. Enriches the soil, keeps it moist and keeps out weeds. I never weed, fertilize or water. Just keep nice thick layer of hay.
But I will pass this idea of the trenches onto younger ones.
