Removing weeds from the garden is always a tiring, challenging chore as weeds can be very "stubborn" to get out of the ground.

If you don't want to use herbicides to eliminate weeds, there are numerous all-natural ingredients that can help you in this regard.

Below, we explain how you can make an effective herbicide using just a few products you probably already have in your pantry:

DIY weed-killer made with vinegar and salt

White vinegar and salt are two easily-sourced ingredients for making an effective DIY herbicide that will not damage the ecosystem. Applied to the leaves and stems of weeds, these two ingredients desiccate and kill off weeds efficiently.

Whilst they can be used individually, these two ingredients mixed together are a very powerful herbicide. Here's a recipe you can follow:

  • mix together one cup of white vinegar, a spoonful of salt and a spoonful of ecological dishwashing liquid in a liter of water;
  • pour the mixture into a spray bottle;
  • spray the mixture over the entire surfaces of the weeds, leaving it to act for 24 hours;
  • after 24 hours, remove the dried-out weeds, making sure not to leave any roots; and repeat this operation if necessary.

This weed control mixture can be stored in an air-tight container and can be reused whenever necessary.

In addition to the foregoing, you can use various other natural products as herbicides:

  • sodium bicarbonate (baking soda): baking soda can be incredibly useful in the garden as a herbicide; simply mix it with water in a 1:4 ratio and spray onto the weeds;
  • lemon juice: a common ingredient in the kitchen, the citric acid in lemon juice can kill weeds; again, use lemon juice in a 1:4 ration with water and spray it directly on the weeds;
  • Castile soap: thanks to its saponins, you can spray this soap directly onto the weeds (after mixing/diluting it with water).

So, how do you choose the most suitable herbicide for your garden? There are different factors that you will have to consider here: the type of weeds to be eliminated, for example (some herbicides are more suitable for eliminating annual herbs, while others may be more effective against perennial herbs); the quantity of weeds to be eliminated is also crucial: if there are a lot, more concentrated herbicides are recommended.

All in all, it's worth giving these all-natural weed-killers a try, no?
