The right weed killer depends on the weed and where it is. For young weeds in driveways and beds, an OMRI-listed vinegar burndown works fast; for tough perennials over large areas, a systemic glyphosate concentrate kills to the root. Both demand PPE and careful, label-directed use.
A glyphosate-free, OMRI-listed vinegar weed killer that's great for burning down young weeds on hardscapes — corrosive, contact-only, and best for spot use, not deep-rooted perennials.
- Driveways
- Patios
- Glyphosate free
- Spot treatment
- Organic
Pros
- Glyphosate-free, OMRI-listed burndown that visibly wilts weeds within hours in sun
- No soil-residual activity, so treated areas can be replanted relatively soon
- Effective on young annual weeds in cracks, driveways, and gravel
Cons
- 20% vinegar is corrosive — it can cause serious eye and skin irritation, so goggles and gloves are required (far stronger than kitchen vinegar)
- Non-selective and contact-only: it burns tops but often doesn't kill established perennial roots, so weeds regrow and need repeat sprays
- Works best in hot, sunny weather; can damage any green plant it drifts onto
A conventional, budget systemic herbicide for clearing large or perennial weed problems root-and-all — powerful but non-selective, so use PPE, follow the label, and consider lower-toxicity options for small jobs.
- Large areas
- Perennial weeds
- Systemic kill
- Fence lines
Pros
- Systemic action kills weeds down to the root, including tough perennials that vinegar only burns back
- Very economical — a small concentrate bottle makes many gallons of spray for large areas
- Rainproof within about 2 hours and effective on a broad range of weeds and grasses
Cons
- Non-selective — will kill any green plant it contacts, including lawn grass and garden plants
- Synthetic herbicide with label PPE and re-entry requirements; glyphosate is subject to ongoing health debate and some local restrictions — read the label and check local rules
- Can move within/through plants and requires care near desirable roots, water, and pollinator-visited blooms

Frequently Asked Questions
- Is vinegar weed killer as strong as glyphosate?
- No. Horticultural 20% vinegar is a contact burndown — it wilts weed tops fast but usually doesn't kill established perennial roots, so weeds regrow. Glyphosate is systemic and kills to the root, but it's non-selective and synthetic. Match the tool to the weed.
- Are these weed killers safe around vegetables?
- Both are non-selective and will damage any green plant they touch, so keep them off desirable and edible plants. Spray on a calm day to avoid drift, wear gloves and eye protection, and follow the label's replant intervals before planting treated soil.
