3. Add a Weed Barrier

Completely cover the ground with the cardboard except where there are plants that you plan to keep.
Wet down the cardboard as you go to keep it in place and to shape it around obstacles.
  • Add a weed barrier that is permeable to water and air, cardboard boxes are ideal. 'Scavenged' cardboard boxes can be found at appliance stores or bike shops. You can also buy recycled cardboard rolls. Do not use plastic or types of weed cloth which will not degrade.
  • Overlap the pieces by 6-8 inches so the sun won’t get through. Any lawn showing at the end of the project will come right back.  Two layers of cardboard works well.
  • Wet down the cardboard as you go to keep it in place and to shape it around obstacles.
  • Work around existing plants by ripping and folding the cardboard. It’s easier to rip once wet.
  • Completely cover the ground with the cardboard except where there are plants that you plan to keep.
