Product Overview
This easy-to-use Jonathan Green Soil pH Test Kit determines pH levels in just ten minutes. The kit includes 10 pH test capsules, one water dropper, a color comparator, complete instructions for adjusting soil pH, and a pH preference list for over 450 plants for the lawn, garden, and home. It is important to use either distilled water or rainwater when performing this test in order to get accurate pH readings. Tap water has been pH adjusted by municipal water authorities and will affect the reading.

When testing and amending your lawn’s soil pH, aim to get your soil’s pH between 6.2 and 7, as turfgrass thrives in slightly acidic to neutral soil.

  • How do I test soil pH?

    You can test your soil’s pH by sending a soil sample to your state university cooperative extension office, who will send it off to a lab for a small fee, or by using an at-home testing kit.


    To perform a soil pH test with the Jonathan Green Soil pH Test Kit, follow these steps:


    1. Collect soil samples from your lawn

    Gather small soil samples from four different sections of your lawn by using a gardening trowel to dig four to six inches deep into the lawn’s surface. Mix all four small samples together for one, cohesive sample to use for your test. Make sure to remove all debris from your sample and proceed to the next step.

    2. Fill test container with soil sample

    Once you have your comprehensive soil sample, remove the cap off of the color comparator and take out the capsule. Make sure the pH color chart is in place, then fill the test container with your prepared soil sample. Carefully separate the two halves of the capsule and pour the contents into the test container.

    3. Add distilled water to the test container

    Using the provided dropper, add distilled water to the test container. Do not use tap water for your soil pH test, as it usually contains acidic or alkaline components.

    4. Shake test container and allow to settle

    After adding distilled water to the test container, shake thoroughly and allow the test container to settle for one to five minutes.

    5. Observe test container for results

  • How to take a soil sample

    Steps to take a soil sample


    • With a shovel or a spade* dig a V-shaped hole to sample depth of 4-6 inches (excluding any thatch), then cut a thin slice off to the side.
    • Do this in 4 or 5 places in the section of the lawn to be tested.
    • Mix soil samples together in a clean, plastic bucket. If the bucket has been used to hold fertilizer or other chemicals, wash it thoroughly before using it for soil samples.
    • Let the sample dry well before testing. Place it in a ziplock bag or coffee can. Approximately one quart is recommended.
    • Make sure to use distilled water for testing.


    *Tools should be either stainless steel or chrome-plated. Do not use brass, bronze, or galvanized tools because they will contaminate samples with copper and/or zinc.

How to Use


  • Using a trowel or soil sampler probe, take soil samples from several parts of your lawn. Avoid touching the soil with your hands.
  • Place your soil samples into a clean container.
  • Mix soil samples together thoroughly, breaking up the samples with a trowel or large spoon.
  • Remove any small stones, organic material such as grass, weeds, or roots, and hard particles of lime.


  • Remove the cap from the comparator and take out the package of capsules. Make sure the color chart (film) is in place.
  • Fill the test chamber to the soil fill line with sample soil.
  • Holding the capsule horizontally over the test chamber, carefully separate or cut the two halves of the capsule and pour the powder into the test chamber.
  • Using the dropper provided, add the distilled water to the water fill line.
  • Fit the cap onto the comparator, making sure it is sealed properly and caps tightly. Shake thoroughly.


  • Allow soil to settle and color to develop for about a minute.
  • Compare the color of the solution against the pH chart. For best results allow daylight (not direct sunlight) to illuminate the solution.
