Use Vinegar or Baking Soda to Kill Weeds Dengarden


Are you tired of using harsh chemicals to get rid of weeds in your garden? Do you want a natural solution that won’t harm your plants or the environment? Look no further than your kitchen cabinet for a simple and effective solution – baking soda.

What is Baking Soda?

Baking soda, also known as sodium bicarbonate, is a naturally occurring substance that has many household uses. It is commonly used in baking as a leavening agent, but it also has cleaning and deodorizing properties. Baking soda is a mild alkaline substance that can help to neutralize acids and break down proteins.

How Does Baking Soda Work to Kill Weeds?

When baking soda comes into contact with weeds, it absorbs moisture from the plant, causing it to dry out and die. Baking soda also has a high pH level, which makes it difficult for weeds to survive. It essentially creates an inhospitable environment for weeds to grow.

How to Use Baking Soda to Kill Weeds

Using baking soda to kill weeds is easy and inexpensive. Here’s how:

Step 1:

Mix one tablespoon of baking soda with one gallon of water in a large container. Stir until the baking soda is completely dissolved.

Step 2:

Pour the mixture into a spray bottle or garden sprayer.

Step 3:

Spray the solution directly onto the weeds, making sure to coat the entire plant. Be careful not to spray any nearby plants that you want to keep.

Step 4:

Wait a few days for the weeds to die off completely. You can then pull them out of the ground or simply leave them to decompose.
