Trees, Shrubs, Vegetables, and Flowers

AN ACCURATE SOIL test will tell you where your pH currently stands and will
specify the amount of lime or sulfur that is needed to bring it up or down
to the appropriate level. A pH of 6.5 is just about right for most home
gardens, since most plants thrive in the 6.0 to 7.0 (slightly acidic to
neutral) range. Some plants (blueberries, azaleas) prefer more strongly
acidic soil, while a few (ferns, asparagus) do best in soil that is neutral
to slightly alkaline. Acidic (sour) soil is counteracted by applying finely
ground limestone, and alkaline (sweet) soil is treated with gypsum (calcium
sulfate) or ground sulfur.
