Mix the Ingredients
In a large spray bottle or bucket, combine the vinegar and salt. Stir well until the salt dissolves completely. Add the dishwashing liquid and mix gently to avoid excess foam. -
Apply Directly to the Weeds
On a dry, sunny day, spray the solution generously on the leaves and stems of the weeds. The sun helps boost the weed-killing effect by dehydrating the plants faster. -
Avoid Overspray on Desired Plants
This natural weed killer is non-selective—it will damage or kill any plant it touches. Protect flowers, vegetables, and lawn grass by applying only to the targeted weeds. -
Repeat as Needed
For tough or deep-rooted weeds, reapply after 2–3 days until the plant is completely wilted and dry.
⚠️ Important Tips & Precautions
-
Best used in non-planting areas like walkways, driveways, gravel, and fence lines.
-
Avoid spraying before rainfall, as water will dilute the solution and reduce effectiveness.
-
Wear gloves if you have sensitive skin, as vinegar can be irritating.
-
Do not use in vegetable beds unless you’re targeting weeds away from crops.
🌿 Why This Works — The Science
-
Vinegar is acidic and dries out plant tissues quickly.
-
Salt dehydrates plants, disrupting their water balance and preventing regrowth.
-
Dishwashing liquid breaks down the waxy surface of leaves, allowing the vinegar and salt to penetrate more effectively.
This combination acts as a natural herbicide that works within hours on small weeds and within days on larger ones.
