Aluminum sulfate is faster acting than elemental sulfur because it is very soluble. Aluminum sulfate and elemental sulfur can be safely used by homeowners. Green industry professionals however, occasionally use sulfuric acid to reduce soil pH around large, established specimen trees.

Sulfuric acid (commonly available as battery acid) is fast acting, but is very dangerous, and its use by home gardeners is not recommended. The choice of which material to use depends on how fast you hope the pH will change and the type/size of plant experiencing the deficiency. Soil pH can be reduced most effectively by adding elemental sulfur, aluminum sulfate or sulfuric acid. In these soils, consider growing plant species more tolerant of high pH conditions. This is an unfortunate characteristic of soils in some parts of Wisconsin. If soils have a pH above 7.5, adding a soil amendment will probably not reduce pH much because of the ‘free’ calcium carbonate or marl present in these soils.

For soils having a pH of less than 7.5, you should be able to add a soil amendment (e.g., some form of sulfur) and successfully lower pH, if recommended. To determine current soil pH, start with a soil test. Blueberries, rhododendrons and azaleas however, are quite intolerant of alkaline conditions and the soil pH must be maintained at 5.5 or less in order to grow them successfully. Turf, vegetables, annual ornamentals and most perennial ornamentals are very tolerant of a wide range of soil pH levels, and acidifying soil is generally not necessary or recommended. Only a soil test for pH can indicate whether the pH is ‘right’, and ‘right ‘ really depends on the plant you want to grow and the natural pH of your soil. Is your soil pH too high? Probably not, although the popular press urges most gardeners to question whether their garden soil pH is ‘right’.
