If you mean a homemade weed killer, be careful: many viral “recipes” (especially those using strong acids, excessive salt, or unsafe chemical mixtures) can damage soil, harm nearby plants, and create safety risks.
For a simple, lower-risk approach:
Option 1: Vinegar-based spot treatment
- Use household vinegar (commonly 5% acetic acid) as a spot spray on unwanted weeds.
- Apply on a dry, sunny day.
- Spray the leaves directly, avoiding grass, flowers, and garden plants you want to keep.
- It works best on young weeds; established perennial weeds may regrow.
Option 2: Non-chemical methods
- Pull weeds after watering when soil is soft.
- Use mulch (wood chips, straw, or leaves) to block sunlight.
- Use boiling water carefully on weeds growing in cracks in driveways or paths.
Avoid mixing vinegar with bleach or other cleaners—dangerous fumes can form. Also avoid using large amounts of salt in soil areas where you want plants to grow, because it can make the soil unsuitable for vegetation.
If you tell me where the weeds are (lawn, driveway cracks, garden beds, or around trees), I can suggest the safest method for that situation.
