9 natural herbicides that you can prepare at home to eliminate weeds and protect your flowers

Are you opposed to using the chemical herbicides available on the market, but you are too lazy to remove the weeds from your garden manually? 

Fortunately, for you, there is a solution, it is economical and environmentally friendly, at least much more so than the chemical herbicides!

Here's what you can do just by utilizing practically only the things you already have in your house and most of all without damaging your beautiful flowers.



  • Baking Soda. This ingredient is great for preventing weeds from growing. However, it can also eliminate those already present. Just cover them completely with a tablespoon or more of baking soda, sprinkling it on the leaves and roots of the weeds.
  • Cooking salt. Cooking salt prevents weeds from taking root, and eliminates them slowly. You can sprinkle salt directly on the weeds, or boil a solution of salt water in a ratio of 1:2 and spray the solution on the affected areas. 
  • Paper newspapers. Place the pages from the newspaper where you want to totally eliminate the weeds, perhaps where they are already deeply rooted. You can get rid of the weeds with a few sheets of newspaper, that will deprive them of the air and light, necessary for growth. 
  • Corn flour. Sprinkle some corn flour where you want to eliminate weeds that are already present or where you do not want them to grow. 
  • White vinegar. White vinegar acid is excellent for killing weeds. Spray a little white vinegar on weeds regularly, more frequently if it rains right after an application.


  • Boiling water. There is nothing more natural than a herbicide based on boiling water. And it works! 
  • Dishwashing liquid.  If you are desperate, you can try to prepare a powerful homemade solution based on dishwashing liquid combined with white vinegar, cooking salt, and dishwashing liquid in equal parts, pour everything into a spray bottle and spray the weeds. 
  • Mulch. You can also think about mulching your plants or covering the base of the plants you are growing and the surrounding soil with a natural cover such as tree bark, pebbles, gravel, etc. and in this way, you will smother the existing weeds and at the same time keep them from re-growing. 
  • Vodka. Make an organic weed killer spray by combining two tablespoons (30 ml) of vodka and a few drops of dishwashing liquid to two cups of water.
