Acidic soils are commonly referred to as "sour." Acidity is the characteristic of soils that have a pH level of less than 7. Such a low pH is suited to plants that thrive in acidic soil (as opposed to alkaline or "sweet" soil), including the delightful 'Minuet' laurel shrubs.
To satisfy plants that crave acidity (often called "acid-loving" plants), acidity can be raised (meaning soil pH will be lowered) by using commercial fertilizers containing ammonium-N, an ingredient that will be found, e.g., in fertilizers sold specifically for azaleas and blueberries.
By contrast, plants that like sweet soil may perform poorly in acidic soils. Soil pH can usually be raised by applying lime
