Testing your soil pH with vinegar and baking soda


Knowing the pH level of your soil can make a difference for the future state of your plants. A slight shift in it’s pH level can noticeably increase and accelerate your plant’s growth

For majority of plants, the ideal soil pH is a neutral level. Using a test probe, a neutral level soil will register as a seven. But even without a test probe, there are other ways to measure your soil's pH level.

One way is by using simple household items like vinegar, baking soda and water. The best news is it doesn’t even take any time at all!


How to test your soil’s pH with vinegar and baking soda

Estimated time: 5 minutes


You will need


Two bowls


Baking Soda

Distilled Water



  1. Scoop three to four spoonfuls of soil in each of the bowls
  2. In one bowl, add water to the soil until it turns muddy. More water than soil should do the trick. Then add at least a quarter cup of baking soda to the mix. If the soil fizzes or forms bubbles, you soil’s level is acidic, below the neutral level.
  3. In the other bowl, add vinegar to the soil. If the soil fizzes or forms bubbles, your soil’s level is alkaline, above the neutral level.
  4. If neither bowls fizz, rejoice! You soil is alive with a neutral pH level. 
  5. Optional: If both bowls fizz, conduct the experiment again.

Once you determine the level of your soil, you can do one of two things: begin planting or adjust your soil level.

If however you want to change the levels of your soil, do not fret. Changing the soil’s levels is a lot simpler than you may think, all you need is patience to watch your soil to improve. We have a simple guide for that here.
