Plants are happiest when their soil is at the right pH. Adjusting pH isn’t rocket science. Soil pH test kits, such as C-I-L® Soil Test Kit, and adjusters like C-I-L® Dolomitic Limestone or GreenEarth® Granular Gypsum are widely available and easy to use. Follow these short steps to help your plants thrive.
Test the area of soil you are concerned about with a soil pH test kit. Most plants grow well in soil with a pH between 6.0 and 6.8, but some do better if the soil pH is a little higher or slightly lower. Check our plant pH preference chart for your plants’ preferred pH.
If your soil pH is too acidic, apply lime. If your soil is too alkaline, apply sulphur or gypsum. The product you use will have a recommended amount.
Soil pH changes slowly, but it does change. Continue to check your soil every year or two, or more often if your plants do not grow well despite proper fertilization.
