Knowing your soil's pH is an important aspect of gardening. Most plants grow well in neutral soil, with a pH level around 6.5. Levels above seven mean that your soil is alkaline, and pH levels below seven mean that it is acidic. Most plants that thrive in neutral soil can handle a little bit of acidity or alkalinity. However, soil that is too far on either end of the spectrum may only be suitable for certain plants unless it is amended to neutralize its pH.
Water the soil.
Remove the top two inches of the soil.
Stick the probe four to five inches into the soil. Twist the probe around a bit to ensure that it has sufficient contact with the soil.
Leave the meter in the soil for at least 60 seconds.
Read the meter. In analog models, an indicator will point to the specific pH of your soil. Digital pH meters will display a number indicating the pH of your soil.
