Agricultural Sulphur (Lowers PH) x 3kg

Directions for use

Lowering Soil pH: Prior to application determine the pH of your soil. Use a pH test kit or probe to determine the pH level to be achieved. To lower the pH of the top 10cm of soil by one unit. e.g. pH 7.5 to pH 6.5 use the following number of grams per square metre:
Sandy Soil - 25 - 50 grams
Loam Soil - 50 - 80 grams
Clay Soil - 80 - 120 grams
Important: Work into the top soil and water in well. Avoid contact between plant foliage and Sulphur. If contact occurs wash off thoroughly with water.

Applying to a volume of soil: To reduce the pH by one unit add approximately 400 grams per cubic metre (1000 litres) of soil or potting mix

To correct a Sulphur element deficiency: Apply 25 grams to each square metre of soil, work into top soil and water in well.

Note: 1 heaped tablespoon holds approximately 20 grams of sulphur

Important Note

Sulphur is one of the essential elements to plants. It is necessary for the formation of Chlorophyll - the green, light absorbing pigment in plants. A sulphur deficiency results in yellowing, usually of the whole plant, small leaves with rolled down edges. Sulphur is also the most economical and effective way to lower the pH of soil. This is particularly important when growing azaleas, camellias and rhododendrons, as these plants prefer strongly acidic soils.
Note: Sulphur is recommended for acidifying soils with a pH of 8.5 or less. Soils with a pH above 8.5 usually contain high levels of limestone which would require excessive applications of sulphur and may give disappointing results.

Important Note: Sulphur is insoluble in water. When applied to soil, it is gradually converted to acid and reduces the soil pH. The actual effect of pH change can be observed after approximately 4-6 weeks. Hence it is very important to monitor the pH after this period and repeat the application if necessary.
