Compost as Mulch
Spread 2 to 6 inches of compost as a mulch over your garden instead of bark mulch. The compost does as good a job at keeping the weeds down, while also adding to your soil.
Burnout Instead of Roundup
BurnOut, an all natural grass and weed killer, is made from vinegar (acetic acid), clove oil, lemon, and other natural plant oils. Use it on walkways and other places where weeds are growing where they shouldn't.
Try just plain white vinegar on weeds in walkways and driveways. Careful to hold spray the weeds! Your most inexpensive option--give it a try.
