It works by reducing soil pH levels, making alkaline or limey soils suitable for these plants. Supplied in a 750g pack, Chempak Sulphur can be applied at any time of year, though it is most effective in warmer soil conditions. Mix it into the soil or compost, or apply it as a top dressing and work it into the surface. It is also safe to use around established container plants and can be dug into the top 6-8 inches for new plantings. A typical application rate of 4oz per sq. yd. (135gms per sq.m.) can lower the pH by approximately 0.5 to 1 unit. It is recommended to wait for soil warming to observe the effects, and further application may be needed to achieve the desired pH. Safety precautions: Sulphur is combustible and may release toxic fumes in a fire; use water for firefighting. Store away from heat sources in its original container. Wash hands thoroughly after use.
