I have figured on doing the back to Eden gardening type, for one bed next spring but will get it ready this fall for next spring planting. I live on a gravel pit of large and small rocks some as big as pick up trucks. it drains too well and no matter how much I pick rocks more just pop up and we are talking some the size of giant potatoes. the soil drains well but doesn't hold water at all so even amending and tilling doesn't work here but the lasagna gardening type does work and the back to EDEN works on the same principal. It will work with hard clay type soils also or any type of soil. worst case is you try it in a 10 foot x 10 foot area or smaller and see how it works for you if it fails you tried if it is a success you expand the idea to the rest of the area one strip at a time or all at once. I haven't tilled in three years now and won't till ever if I have my way. I can plant early with the lasagna beds as early as april first it still snows some times on april first have pic to prove it. but the beds are warmer and the dirt is easy to move aside and put seeds in. I just do crops that like to start in the cold first. then they get done and I can do some warmer weather crops in the second go around.
