Step 1: Gather LOTS of newspaper
Step 2: Stockpile grass clippings
Step 3: Plant your garden
Step 4: Lay out the newspaper and cover with clippings
Step 5: Water your garden
You may need to do some minor weeding around the base of the plants but for the most part 95% or more of the weeding you normally do will be eliminated. Add more clipping during the year as needed. At the end of the year, rototill the clippings and the paper into the garden. No need to pull anything up at all. I find this works many times better than just clippings alone.
