Does Baking Soda Kill Weeds?


Baking soda is a common household item that has many uses. One such use is weed control, but does baking soda really kill weeds? Some gardeners swear by it, while others are skeptical.

It is believed that baking soda works as a natural herbicide by interfering with photosynthesis and disrupting the pH of the plant. When applied to the leaves of weeds, it can cause them to dry out and die. However, there is limited scientific evidence to support this claim, and the effectiveness may depend on the type of weed and application method.

While baking soda may not be a guaranteed solution for weed control, it can be used as an alternative to harsh chemical herbicides. It is safe to use around children and pets and can also be used as a general cleaner in the kitchen and bathroom.

According to an article published by The Spruce titled “Using Baking Soda in the Garden,” mixing 1 cup baking soda with 1 gallon of water may help control powdery mildew on plants.

When baking soda meets weeds, it’s a literal and figurative deathmatch.

Understanding the Effects of Baking Soda on Weeds

Baking soda is a common household item used for various purposes, including as a weed killer. Understanding the impact of baking soda on weeds is essential for effective use. Here are some key points to consider:

  • Baking soda works by raising the pH level of the soil, making it more alkaline, which inhibits the growth of plants, including weeds.
  • The effectiveness of baking soda as a weed killer may vary depending on the type of weed and its stage of growth.
  • Baking soda may harm nearby plants and should be used with caution.

It is also important to note that while baking soda may be effective for removing weeds, it is not a long-term solution and may require frequent applications. According to a study by the University of Connecticut, using vinegar as a weed killer is more effective than baking soda.

How Baking Soda Works to Kill Weeds

How Sodium Bicarbonate Eliminates Weeds

To get rid of weeds, using baking soda or sodium bicarbonate is an effective and budget-friendly approach. It works by altering the pH levels and causing dehydration in plants.

A 6-Step Guide to Using Baking Soda to Control Weed Growth:

  1. Prepare a mixture of baking soda and water in a ratio of three tablespoons per gallon.
  2. Incorporate soap or detergent to the mixture as it helps enhance its uniformity on leaves.
  3. Use a spray bottle or garden sprayer to apply the solution onto weeds and avoid spraying adjacent plants.
  4. Wait for sunny weather or a time when rain isn’t expected within at least six hours after application as it allows maximum absorption for the weed-killer.
  5. After approximately two days, monitor the treated area for any leftover vegetation which requires removal using gardening tools.
  6. Avoid planting desirable plants on contaminated soil.

Using Sodium Bicarbonate Considerations

While sodium bicarbonate is an efficient alternative for weed control, it works best with small-scale gardening rather than large farms due to its concentration requirements. Additionally, watering areas with untreated weeds results in new growth; therefore, it needs consistent monitoring.


It is crucial to maintain precision overusing baking soda since over-applying may trigger soil acidity affecting desirable plant growth negatively. For larger gardens, using vinegar, rock salt, or cornmeal gluten meal may be more efficient options for weed reduction while preserving the environment.

Who needs expensive chemicals when you can eliminate weeds with everyone’s favorite baking ingredient? Turns out baking soda isn’t just for muffins and murder scenes anymore.
