“The reason for this is that pH is intimately tied to chemical, biochemical, and biological processes, and their interactions,” says Andrew Margenot, UC Davis.
“Testing your garden soil for pH is a very important step in creating and maintaining the best growing environment,” says Margenot. “We recommend testing pH when you create the garden and every few years thereafter (check with your local extension office for the best recommendations for your area). Remember that different plants may need different pH values, so be sure to consult optimal pH values for a given plant when you are working in your garden and using soil amendments and/or fertilizers.”
