How to use Sulphur Powder in the garden?

Flower of Sulhur plays a very important role in the development of various plants. For cultivated plants, it is not only an ingredient that contributes to proper nutrition, but also plays an important role in their protection. As a protection measure, it is even more important than as a nutrient shaping the size and quality of plants.
- when applied before flowering, it inhibits the development of apple rusty and spider mites. It plays an important role in the protection of apple trees, especially against the most dangerous disease, i.e. apple scab.
- like nitrogen, magnesium, phosphorus, potassium and calcium, sulfur belongs to the macronutrients of plants. With its deficiency, plants cannot function properly, and the symptoms of its deficiency resemble those of a lack of nitrogen. Sulfur supports the absorption of nitrogen from the soil.

Acidification of the soil with Sulphur Powder:

For acidification, sowing of powdery or granulated sulfur is used. It is slow and requires some time to be fully effective. After small doses sown in autumn, you can grow plants in spring, but if you need to use the maximum dose (2.5-3.5 kg./10 m2), you should wait at least one year with the cultivation. Sulfur can also be used after planting the plants, but a single dose should not exceed 50-100 g / 10 m2 of the area in this case.


In order to maintain a low pH level in the cultivation of acidophilic plants, avoid the use of compost, manure, as well as basic mineral fertilizers (e.g. calcium, magnesium nitrate, calcium ammonium nitrate) - they increase the soil pH.

    Hello HD. Is it possible to obtain ‘wetable’ sulphur? I am trying to reduce the tendency for some of my grape vines to annually develop powdery mildew and although I have been recently using sulphur powder from you as a dust I feel a spray schedule would be more effective. As an alternative would sodium bicarbonate spray be as effective and what concentration would you suggest?
    Many thanks, David Lodge
