Testing Soil for pH
Determine the pH of your garden soil with an easy-to-use test kit from a garden center or hardware store.
Step 1: Take Samples
Take samples from different parts of the garden, as soil is seldom uniform. Make a note of where each sample comes from so that you can exploit any variations, such as an acidic patch, when you draw up your planting plan. Add the soil to the chemical solution in the test tube and shake to mix.
Step 2: Match Solution Colors to the pH Chart
Dark green indicates alkaline soil, bright green is neutral, and yellow or orange indicates acidic soil.
