17. Adjust Soil pH
If you want to grow a specific shade of Hydrangea or an acid loving plant like Blueberries, the pH, which refers to the relative acidity or alkalinity of your soil, is incredibly important. Some region’s soils are naturally more acidic or alkaline than others, while other factors like adjacency to acidic trees like pine trees can significantly affect the dirt.
There are many kits available at garden centers and big box stores that allow you to test your soil and get a relatively accurate reading of the pH. If you are planning on doing a large landscaping project, take several tests throughout the project area as the pH can vary widely, even within relatively small areas.
