Vinegar Beats Weed Barriers for Schoolyard Weed Control

After landscape fabric and rock mulch failed to stop weeds in a Sunday school yard, the answer is simple: vinegar. Weeds grow in soil that accumulates on top of barriers. Vinegar (5% household, 14% pickling if available) sprayed on hot days kills top growth safely—no toxic residue for children or pets.

Why Barriers Fail

• Blown-in soil creates a seedbed atop fabric.
• Less than 3 inches of mulch lets light through.
• Plastic barriers create anaerobic, sour soil underneath.

Vinegar Application

Fill a garden sprayer with straight vinegar. Spray thoroughly on a hot, sunny day. Reapply every few months as needed. Cheaper and safer than Roundup or Ortho products, which only kill contacted roots and leave poison residues.

For total vegetation elimination (playgrounds), vinegar works. For lawns, build rich soil organically—weeds won't thrive there.
