How To Lower pH In Soil With Vinegar

Plant growers need to have some basic knowledge about the pH factor of their soil. They need to know this before they start their garden. Soil pH, simply defined, is a measure of the soil's acidity and alkalinity.

The measured levels range from 0 to 14, with 7 being neutral, below 7 acidic and above 7 alkaline. The optimal pH range for most plants is between 5.5 and 7.0. However, many plants have adapted to thrive at pH values outside this range.

Your plants of choice may prefer either an acidic soil or an alkaline soil. Just bear in mind that plants grown outside their preferred pH will not thrive well. If for instance, you plan to grow azaleas, lilies or hydrangeas, they will thrive in acidic soil with a pH level of 6. Other plants like thyme and geraniums prefer alkalinity with a PH level of 7 or more.

​Do you know how to lower pH in soil with vinegar? Knowing it and doing this enables the garden soil to grow your choices. There surely is a way and it involves two very common chemicals that are already in your kitchen pantry. Vinegar and baking soda can do the miracle for you.

​Soil And Vinegar - Basic Information

As mentioned earlier, different kinds of plants can only survive and flourish in soil with their preferred pH level. With soil pH ranging from 0 to 14 scale, neutral soil has a pH of 7. Below seven indicates that the soil is acidic and above 7 will indicate the soil to be alkaline. Most plants thrive with a pH reading between 6.5 to 7.

Before making any changes to the pH level of your soil, have the soil tested to find out its precise pH level. From such readings, you can start amending your soil's acidity by applying vinegar. Regularly check the pH level. Do this to ensure that your applying of vinegar will not make the soil much too acidic for your plants.

Vinegar in itself is a thinned form of acetic acid. This means that placing it into the soil will naturally increase its acidity. Commercial vinegar found in your grocery store usually has a pH level of 2.4, meaning it's highly acidic. If you are into organic gardening, choose an organic variety of vinegar. There are several brands available out there.

Prepare These Items

1. You'll need a pH meter or some litmus paper. Also, prepare a testing cup.

2. From your kitchen, take some distilled water, vinegar, and baking soda.

Test Your Soil Using A pH Test Kit

  • Determine the pH level of your soil. To do this, you can use a pH meter or even a pH test kit. You can usually find the instructions in the kit.
  • If there aren't any instructions, you can still do it easily. Add a tablespoon of soil in a cup. Then pour some distilled water and put the litmus paper strip or the prong into the soil. Either of these will provide the pH reading.

Test Your Soil Using Materials From Your Home

  • In the absence of a meter or litmus paper, do a homemade version to test the pH of the soil.
  • Take soil samples from your garden. Make sure to take them from the same place. Pour some distilled water on both samples. Add one tablespoon of vinegar to one cup and one tablespoon of baking soda on the other. Then start observing the reactions.
  • If the cup with the vinegar fizzes and bubbles, it means your soil is alkaline given that vinegar is acidic. If the cup with baking soda fizzes and bubbles, your soil is acidic given that the baking soda is alkaline.

Make The Necessary Adjustments To Your Soil

  • Pour vinegar to the soil to lower its pH level.
  • To do this, first, make your vinegar mixture. Combine one cup vinegar to a gallon of water. Then, carefully pour the mixture in the soil to adjust the pH level.
