Are you interested in a garden technique that involves much less work and just as good results as the usual methods? Try Lee Reich's "top down" prescription. In brief it involves protecting the topsoil using:
1) Minimal soil disruption (no digging!)
2) Soil protection (mulching or cover crops--no weeding!)
3) Drip irrigation (if irrigation is needed).
4) Balanced soils (sensible amendments or fertilizers)
The details he provides sound reasonable, and he also quotes many experts or studies to back him up. A good read for either novice or experienced or gardeners. My only caveat is that "weedless" means "almost no weeding", but still that sounds great to me.
