How the substance is used in gardening
Ferrous sulfate is commercially available from horticultural centers. Crystals of turquoise color, they are small in size, dissolve well in water. The substance is contained in the powder at a concentration of 53%, it is diluted with water and used to treat plants.
The following uses are possible:
- spraying;
- whitewash.
Ferrous sulfate has proven itself well, it is used in the following cases:
- destruction of harmful insects that have appeared on landings;
- disinfection of places where branches and hollows are cut, treatment of wounds on bushes and fruit trees;
- combating chlorosis, which occurs due to iron deficiency in the soil;
- treatment of fruit and gray rot, combating scab and powdery mildew, prevention and treatment of other diseases of fungal origin;
- destruction of lichens and mosses that appear on trees.
Vitriol is used not only for treatment, but also for preventive purposes. If it is necessary to destroy pests, a solution is prepared to process the plantings in the following proportion: add 500 g of powder to a bucket with a capacity of 10 liters, stir thoroughly. Trees are processed before buds bloom on the branches. The second procedure is carried out in late autumn, in October or November, the exact dates depend on the region.
If you need to get rid of lichens and mosses, which often begin to grow on old trees, use a solution at a concentration of 3%. To do this, dissolve 300 g of ferrous sulfate in 10 liters of water. The same product is suitable for spraying stone fruit trees and berry bushes. But when processing pome seeds, the concentration should be increased, a 5% solution will work effectively. To do this, dissolve 500 g of the product in a 10 liter bucket.
You need to spray the plants 2 times a year. The first processing is performed in early spring, until green leaves appear on the branches. The second time the trees are cultivated in the fall, after the foliage has fallen off them.
If in the fall after the treatment the lichens have not fallen off, you can spray the trees again, but at least 2 weeks should pass between the procedures. After that, the mosses dry up, the bark becomes clean.
Ferrous sulfate is also effective in the fight against fungal diseases. To cope with them, gardeners should use a solution of lower concentration. For this, 30 g of the substance are dissolved in 10 l of water. Planting is processed 2-3 times, between procedures should pass from 5 to 7 days.
What to look for
Often, with a deficiency of iron in the soil, the plantings change color to a pale green. This indicates that chlorosis has begun. With this disease, less chlorophyll is formed in the leaves, the activity of photosynthesis is reduced because of this.
To combat chlorosis, 50 g of the substance are dissolved in 10 liters of water. Plants are sprayed every 4-5 days until the leaves are bright green. If disease prevention is required, it is enough to add 10 g of ferrous sulfate to the water.
Vitriol is used for disinfection of sections, cracks, treatment of places from which the bark was removed. To do this, make a solution based on 100 g of powder.
When working with ferrous sulfate, gardeners should take the following precautions:
- Strictly observe the proportion. The concentration should not be exceeded, it may harm plantings. Solutions, the concentration of which is 5-7%, can be used only in spring, until the buds bloom, and also in late autumn, when the foliage completely falls off.
- During the growing season, the concentration should not exceed 1%, it is recommended to reduce it to 0.1%.
- You can prepare the solution in a glass or plastic container. You need to work with gloves.
- If the substance accidentally gets into your eyes, rinse them thoroughly with running water.
Summer residents should remember that a concentrated solution of ferrous sulfate that gets on the leaves and green shoots can cause burns. Despite this drawback, the drug is considered universal, it is widely used by gardeners.
