🌿 “This burns weeds in 1 day—and they never grow again” — does it work?
That headline is mostly clickbait. Some homemade treatments can make weeds wilt or turn brown within a day, but that doesn’t mean the roots are dead. Vinegar, boiling water, and similar contact treatments mainly damage the plant tissue they touch; established perennial weeds can grow back from their roots.

What about the famous vinegar + salt recipe?
You may have seen recipes containing vinegar, salt and dish soap. They can burn the foliage of small weeds, but university extension specialists caution against using salt because it can accumulate in soil and damage desirable plants and soil health.

Also, stronger horticultural vinegar is not the same as kitchen vinegar. Concentrated acetic acid can cause serious skin and eye burns, so it shouldn’t be treated as a harmless household ingredient.

A safer natural approach
For a garden or yard, a more reliable long-term strategy is:
Pull or dig young weeds, removing as much root as possible.
Mulch about 3 inches deep around desirable plants to suppress new weeds.
Remove weeds before they produce seeds.
For weeds in cracks in patios or driveways, boiling water can work on young weeds, although deep-rooted plants may return and need repeat treatment.

Bottom line: A weed can look completely dead in 24 hours and still have a healthy root system. There is no universal homemade mixture that guarantees “never again.” For persistent perennial weeds, root removal or an appropriately labeled herbicide is generally much more reliable.
