It’s about time lawn fertilizers were regulated; they’re waging chemical warfare on the Bay
Most of Maryland’s soils are acid. Unless they are limed every three to five years, they are generally too acid for optimum growth, so that any fertilizer applied is wasted and finds its way into the Bay. During the many lectures I give, I always ask who in the audience have had their soil tested in the last five years. I’m lucky to find even a few. Horticulture is a science, not a game for guessing or intuition.
