Indulging in gardening is a rewarding hobby, but pesky weeds can quickly turn your garden into a battleground. Chemical weed killers may be effective, but they can harm beneficial plants and contaminate groundwater. If youre searching for an eco-friendly and cost-effective alternative to tackle those persistent weeds, look no further! In this article, well explore a popular and natural solution: the baking soda weed killer recipe.

Understanding the Power of Baking Soda

What is baking soda?

Baking soda, scientifically known as sodium bicarbonate, is a versatile substance commonly used in cooking and cleaning. This white crystalline powder boasts a range of properties, including being a mild abrasive, deodorizer, and pH buffer.

How does baking soda kill weeds?

Baking sodas weed-killing abilities stem from its disruptive effect on the pH balance of plants. When applied to the leaves or soil, baking soda causes the plants protective cuticle to weaken, leading to dehydration and eventual death. Additionally, baking soda inhibits chlorophyll production, which robs the weeds of vital nutrients, further contributing to their demise.

The Baking Soda Weed Killer Recipe


  • 1 gallon of distilled white vinegar
  • 1 cup of table salt
  • ½ cup of dish soap (preferably biodegradable)
  • ¼ cup of baking soda


  1. In a large container, mix the distilled white vinegar and table salt until the salt dissolves completely.
  2. Stir in the dish soap, ensuring it is well incorporated.
  3. Gradually add the baking soda to the mixture while stirring gently.
  4. Transfer the solution to a spray bottle or a garden sprayer for easy application.

Applying the weed killer:

  1. Select a sunny day to apply the baking soda weed killer, as sunlight improves its effectiveness.
  2. Shake the spray bottle or garden sprayer vigorously to ensure even distribution of the solution.
  3. Aim the nozzle directly at the weeds and apply the solution generously, making sure all parts of the weed are adequately coated.

  1. Wear protective clothing, including goggles and gloves, while handling the weed killer solution.
  2. Keep children and pets away from the treated area until the solution has dried.
