Manutec - Sulphur
Sulphur is one of the essential elements to plants. It is necessary for the formation of Chlorophyll – the green, light absorbing pigments in plants. A sulphur deficiency results in yellowing, usually of the whole plant, and small leaves with rolled down edges. Sulphur is also the most economical and effective way of lowering the pH of soil. This is particularly important when growing azaleas, camellias and rhododendrons, as these plants prefer strongly acidic soils.
Follow the directions on the package and apply accordingly. Sulphur is recommended for acidifying Alkaline soils
