General landscape plants prefer a balanced pH, as these plants absorb the nutrients at hand much more efficiently when in a neutral environment. The Metroplex clay-based soil generally has a pH level of 8.4, which is considered to be very alkaline. Even though our rich native soil may be loaded with nutrients, the elevated pH level prevents the plant from efficiently up-taking the nutrients. Common results associated with high pH include yellowing leaves (Clorosis), stunting, or even plant death. The products in this list will achieve a neutral pH, which makes all the nutrients available to your plants, for accelerated, healthy and vibrant growth.
