Why does soil pH matter?

Most plants prefer a pH of 6.5

Soil pH determines its acidity (sourness) or alkalinity (sweetness). For gardening, most plants prefer a soil pH between 6 and 7 with 6.5 being your target soil pH.

Maintaining proper soil pH prevents "nutrient lockout"

If soil pH is too extreme for plants, it creates an unhealthy environment by limiting the nourishment that is available to the plants.

Maintaining proper soil pH helps promote growth and vigor

Plants under stress are much more prone to poor health. Keeping pH at the proper level for the plants in your garden is one way to help.

Step 1: Collect a representative soil sample

Using a garden trowel or spade, dig a small hole (about 6 inches deep) and slice a sample from the edge of the hole as if you were cutting a thin slice of cake. Put this sample in a bucket or large container. Repeat this process a few times around your garden site. Mix soil samples thoroughly and remove any stones, grass, etc.

Step 2: Add soil to a cup or testing jar

Using a tablespoon put 8 level tablespoons (4 ounces) of the mixed soil into a clean plastic cup or testing jar and thoroughly mix with 8 level tablespoons (4 ounces) of water for 30 seconds.

Step 3: Dip strip into solution

For best results, let the soil/water solution sit for 20 minutes before testing. Briefly mix solution one more time and wait 10 seconds for the soil to settle a bit and then dip one pH test strip into the solution. Hold the strip in the solution for 3 seconds.

Step 4: Match color pads to color chart

Remove the pH test strip and shake it vigorously to remove any dirt on the pads. Depending on soil pH, some or all the color pads will change color. Match the resulting color(s) with the color chart that accompanied the pH test strips to determine your soil pH. If you are having difficulty choosing a pH, use our simplified chart to zero in on your soil pH.
