Frequently asked questions

To use the soil pH test kit, start by collecting a small sample of soil from the area you wish to test. Remove any debris, such as sticks or stones, then wet the soil with distilled water to create a slurry. Dip a pH test strip into the slurry, ensuring it's fully immersed, then wait for the amount of time specified in the kit's instructions. After waiting, compare the color of the strip to the color chart provided with the kit to determine the pH level of your soil.

The ideal soil pH range for most garden plants is between 6.0 and 7.0, which is slightly acidic to neutral. However, some plants thrive in more acidic or alkaline soils. It's important to know the specific needs of the plants you're growing, as the correct pH is crucial for nutrient availability.

Yes, the soil pH test kit is suitable for testing the acidity and alkalinity of soil for both indoor and outdoor plants, including garden lawn grass, flowers, vegetables, compost, and more. It's a versatile tool for gardeners and plant enthusiasts to ensure the health and growth of their plants by maintaining the optimal soil pH.

Testing soil pH before planting is important because it helps you understand the soil's acidity or alkalinity, which significantly affects plants' ability to absorb nutrients. If the soil pH is too high or too low for your plants, it can lead to nutrient deficiencies, poor growth, and a lack of vitality. By knowing the soil pH, you can take corrective actions, such as applying lime to raise pH or sulfur to lower pH, to create the ideal growing environment for your plants.

    • Pretty easy to use; accceptable accuracy; cost effective
Size: 1.9L x 1.9W x 4.3H
While using this kit involves a lot more work than the 'push it in and read' type of pH testers, the results are way more accurate than what I got with inexpensive probe-style readers. The cost per test is very reasonable and the instructions provided with the kit are clear and detailed. My biggest hurdle using it was distinguishing the colors on the test strips to compare them with the color key. A larger key and larger strips would have made that easier. While nothing beats the accuracy of a true lab test, for my home garden this kit has been far more helpful and useful than the inexpensive probe readers. Not perfect, but a very workable option to determine soil pH. ... show more

    • Finally I have a test for accurate pH in my soil!!
Size: 1.9L x 1.9W x 4.3H
I tried several meters to test soil pH and they weren't accurate. So I decided to try these pH test strips from Garden Tutor. I finally got an accurate reading. It was hard to determine some of the shades of color against the bottle so I put the test strip into the guide and sent it in to Garden Tutor. Within a few minutes my test strip had gone though their computers, read my strip and sent me back an email with the exact pH. Finally I have a test for pH that I can count on to be accurate. I give Garden Tutor 5 stars for great work and results within minutes!! Thank you. Betty Chase ... show more

    • How accurate are these ph test kits?
Size: 1.9L x 1.9W x 4.3H
Difficulties when getting accurate ph on color chart. In addition, there seems to be a wide disparity between AI ph result and manual ph test results from the chart. AI says 6.3 ph, and manual says 8 or 9 ph. Still usuable.

    • Seems accurate if used correctly
Size: 1.9L x 1.9W x 4.3H
Found the strips easy to use. As directed, 1/2 c of distilled and 1/2 c of soil...mix...wait 30 minutes. Swish just inside the mixture and shake off. I have 2 different gardens and I got a 6.5 on one and a 6.4 on the other. I will use periodically throughout the growing season, too.
