4. Kill and Prevent Weeds
Forget chemical applications and use a tarp as a substitute. To use a tarp to kill weeds and grass, place the tarp on the section to kill. Then stake down the tarp and add weight to it. The time it takes the vegetation to die will vary upon weed type, region, and season. Note: It may be necessary to cut holes in the tarp for it to lay flat on the ground.
