Searles Iron Sulphate 500g
Essential element in the formation of Chlorophyll.
Deficiency symptoms vary somewhat with plant species, however a general symptom is the yellowing in between leaf veins. This is most noticeable in the younger leaves. There is usually a sharp distinction between the yellow and green portions. Fruit may also have poor colour. In severe cases, the whole leaf turns yellow, including the veins.
Some Australian native plants are very sensitive to the nutrient Phosphorus(P). Iron sulphate can be beneficial for use around these plants as the iron sulphate helps to lock up phosphorus in the soil and acidify the soil at the same time.
Simply sprinkle some iron sulphate onto the soil around these plants and water in. Not only will it help deliver essential Iron to these plants but also reduce the soil pH which in turn helps to make the Iron in the soil more beneficial. For severe cases of high pH (over 7), use Sulphur Powder to reduce pH, however in mild cases the Iron sulphate will achieve a beneficial and satisfactory result.
