Sulphur powder, also known as agricultural sulphur, is an excellent acidifying agent for lowering pH of alkaline soils.
This is very important for plants that require acidic conditions such as azaleas, camellias, gardenias, rhododendrons, ericas, hydrangeas, philodendrons & other acid loving plants. Work the Sulphur powder into the soil and water in well. Deficiencies of Sulphur result in restricted growth and yellow leaves.
