When it comes to gardening—especially when we’re growing fruits and vegetables we plan to eat—reducing the use of chemical products becomes even more crucial.
But how can we eliminate weeds without risking contamination of the soil or nearby edible plants?
Good news: there’s no need to prepare complicated mixtures with dozens of ingredients. With just one or two natural components—often already in your kitchen—you can make an effective homemade weed killer that’s safe for your garden.
Effective Homemade Weed Killers
Here are 5 simple natural weed killer recipes to try today:
White Vinegar: A Time-Tested Classic
This is one of the most effective natural weed killers. To make a less acidic but still powerful solution, combine:
1 liter of white vinegar
2.5 liters of water
500 grams of coarse salt
Mix well and apply using a watering can or spray bottle. Weeds will dry out quickly and become easy to remove.
Potato or Pasta Cooking Water
Simple, budget-friendly, and zero waste! Rich in starch, this water weakens weeds without harming the soil.
Keep the cooking water while it’s still hot (preferably unsalted), and pour it directly onto the areas you want to treat.
Baking Soda
A multi-purpose household staple that also works as a natural herbicide:
70 grams of baking soda per liter of hot water
Apply to the affected areas, but limit use to twice a year to avoid disrupting the soil’s natural balance.
Wood Ash
Ideal if you have a fireplace or wood stove. Wood ash is both a powerful natural weed killer and a great fertilizer.
Simply sprinkle it over mossy areas or spots with unwanted weeds.
Basil Essential Oil
The most expensive option, but highly concentrated and effective. Basil essential oil has natural herbicidal properties:
Add a few drops to 1 liter of water
Mix in a small amount of natural soap (like black soap)
Spray generously on the weeds
