How to Make Homemade Roundup to Kill All Weeds

Weeds can be a real nuisance. They steal nutrients, water and sunlight from desirable plants, and they make lawns and parks look unsightly. Moreover, some weeds serve as food sources for pests (such as grasshoppers). Roundup is a chemical herbicide designed to kill broad-leafed weeds.

Pulling weeds by hand can be laborious.

While you cannot duplicate Roundup exactly at your home, you can make a weed-killer that mimics Roundup.

  1. Purchase a bottle of distilled vinegar, such as Heinz or Mizkan.

  2. Pour the distilled vinegar into a watering can or spray bottle.

  3. Cover any plants that you do not want to harm with a plastic sheet.

  4. Spread the distilled vinegar over the weeds. Distilled vinegar contains a high level of acid and will kill any weeds it comes in contact with.


Other homemade Roundup alternatives include rock salt (will ruin soil and prevent future growth), boiling water and rubbing alcohol.


Any homemade weed killer will be nonselective, meaning that it will kill anything it touches -- including desirable plants and grasses. If this is a concern, consider purchasing a selective herbicide or weeding by hand.
