Soil pH

Soil pH

Soil pH can occasionally be a factor. Fortunately, the St. Louis region generally has neutral or slightly acidic soil. Most Missouri native plants will thrive in St. Louis, and surrounding counties. if you are especially concerned about any particular area of your lot, a soil test is an easy and inexpensive way to assess if there is a problem with soil chemistry or composition. There are many online resources on this subject. The first link below is a short video with Nathan Brandt from the University of Missouri Extension instructing on the techniques of soil sampling.
