It is impossible to grow a healthy garden without periodically treating trees and shrubs with protective agents against pests and diseases. One of such means is iron vitriol.
Ferrous sulfate (according to the chemical formula - ferrous sulfate) is a small turquoise crystals, soluble in water. The content of the active substance in the finished powder is 53%. Usually, iron sulfate is used as an aqueous solution for spraying or as a part of whitewash for trees and shrubs.

Application of ferrous sulfate
Ferrous sulfate is traditionally used for:
- destruction of harmful insects;
- prevention and treatment of fungal diseases (scab, blotches, powdery mildew, fruit rot, gray rot, black cancer, etc.);
- getting rid of moss and lichen;
- disinfecting wounds and hollows in trees;
- treatment and prevention of chlorosis (plant diseases arising from a lack of iron in the soil).
Vs harmful insects (including hibernating under the bark) iron sulfate is used at a concentration of 500 g per 10 liters of water. Trees are abundantly sprayed with this solution before bud break. The second treatment is carried out in late autumn - in November.
Iron vitriol against mosses and lichens
To get rid of lichen and mossesthat often appear on old trees, iron sulfate is also very effective. Berry bushes and stone trees are sprayed with a 3% solution (300 g of iron sulphate per 10 liters of water). Seed trees require a more powerful concentration - 500 g of iron sulphate per 10 liters of water.
It is not easy to remove moss and lichens from trees, but after treatment with a solution of iron sulphate, they themselves leave the bark
Spraying performed in early spring or autumn, when the leaves have fallen. As a rule, two treatments are needed at intervals of two weeks. After that, mosses and lichens die and fall off the bark themselves.
Fight against fungal diseases
To cope with fungal diseases, a weaker solution of ferrous sulfate (30 g of substance per 10 liters of water) is used. Treatments are carried out 2-3 times every 5-7 days.
Disinfecting Trees with Iron sulfate
During wound disinfection, cracks, hollow 100 g of ferrous sulfate is diluted in 10 liters of water. The resulting solution is treated with damaged tree tissue.
Iron sulfate against chlorosis
Spraying of iron sulphate helps to get rid of chlorosis that occurs in plants due to a lack of iron in the soil or a lack of fertilizer. To prepare a solution, 50 g of ferrous sulfate is dissolved in 10 liters of water. Spraying performed every 4-5 days to restore the green leaf color. For the prevention of chlorosis, a lower concentration is effective: 10 g of vitriol to 10 liters of water.
Precautions when working with the drug
Iron sulfate is an unsafe substance. To prevent it from harming you and your landings, follow certain rules for working with it:
1. Carefully read the recommended concentration of the solution in the instructions. 5-7% solutions may be used only in spring (before bud break) or in autumn, when there are no leaves on the plants. During the growing season should prefer lower concentrations (0.1-1%).
2. Dilute iron vitriol in glass or plastic dishes.
3. Wear gloves.
4. In case of contact with ferrous sulfate in the eyes, rinse thoroughly with running water.
Iron sulfate, caught on the leaves and green cuttings, can cause their burns.
Proper use of ferrous sulfate will help rid the trees in your garden from insect pests, fungal diseases, mosses, lichens and other ailments. No wonder this drug is considered the most versatile in gardening.
