What’s a Good pH Number?

The pH of a soil is shown by a numbered scale which goes from 1 to 14. Any number below 7 is known as acidic soil. Anything above 7 means your soil is alkaline. The Goldilocks zone, which is the pH that is just right for most plants, goes from 6.2 to 7.2. Although there are some plants that do better with acidic soil, the majority of plants will be best served by a neutral soil.

When to Test

You can test your soil at any time during the year, but if you have a lot of plants you’ll be putting in during the spring or fall, you may want to test the soil before then. If your soil isn’t the right pH, you’ll have time to take corrective measures before you plant.

What Kinds of Testers Are Available?

Soil pH testers come in three different types. There are pH test strips, chemical colored dyes and meters.

Test strips can be tricky if you aren’t good at distinguishing subtle shades of color. The colored dye testers also require you to use a color chart to determine the pH level, but it doesn’t generally require as much distinction between shades. The meters use a probe that you stick into a soil and water mixture, or directly into the soil in some cases. You can then read the results off a numbered gauge on the unit.
