Non‑Toxic Weed Control in Landscape Stone Around a Pool

Organic Option: Vinegar

Undiluted household vinegar (5% acetic acid) or horticultural vinegar (20%) can kill emerged weeds. It’s non‑selective, contact‑only (no root translocation), so repeat applications are needed for perennials. Safe for stone, but avoid overspray on desirable plants.

Herbicide Option: Glyphosate (RoundUp)

Glyphosate is absorbed through leaves, moves to roots, and kills the whole plant. It degrades quickly in soil (no long‑term residue). Once leaves dry (few hours), it’s safe for people/pets. Precautions:

• Spray on calm, mild day (40–75°F).
• Wet leaves only; no runoff.
• Wear protective clothing; avoid inhaling mist.
• Shield pool water and desirable plants.

Comparison

Vinegar: organic, repeated effort, no soil residue.
Glyphosate: systemic, longer control, low environmental persistence when used correctly.

Choose based on weed type and personal preference.
