A variety of preparations can be purchased in a specialized store, the main task of which is to protect fruit-trees from various diseases and pests. However, not every such product is highly effective and often inadequately priced. In this regard, experienced gardeners advise using a time-tested preparation for this purpose - iron sulfate.
Iron sulfate - what is it?
Iron sulfate has another chemical name - iron sulfate. It is quite popular with gardeners and has been used in horticulture for many years.
Externally, this remedy looks like a crystalline powder, colored pale green. The concentration of the main active component is within 53 percent.
This remedy is essentially a salt formed by the interaction of divalent iron and sulfuric acid. This substance is a crystalline hydrate, and all because each of its molecules combines with 7 molecules of water.
What is it used for?
This remedy is a favorite among long-time gardeners.
And iron sulfate owes its popularity to its rather broad action and its low price.
Horticulture uses this preparation for the following purposes:
- Spring and autumn whitewashing of the surface of tree trunks growing in the garden.
- To get rid of lichen, moss and other fungal diseases.
- To treat grapes as a preventative against a variety of diseases.
- To eliminate the black spot of roses.
- To strengthen trees that are already quite old.
- To kill harmful insects.
- It can be used to heal wounds present on the trunks of fruit orchards.
- To saturate the soil with iron.
This product is not only used in horticulture as it is able to control fungus present on the surface of the walls of the house or the room where vegetables are kept.

Peculiarities of use
This product can be used to treat garden crops only 2 times in a season, namely at the beginning of the spring and in the fall.
Young trees should be treated only in early spring, before buds open, while old trees need a second treatment in the autumn.
It is important! Iron sulfate is not mixed with lime (only with copper sulfate).
The strength of the solution may vary for different purposes:
- A 5% solution is suitable for killing fungal diseases on fruit crops in early spring.
- Only a 0.5%-1% solution is used for preventive purposes.
- The 0.3% mixture is used for rose spraying.
- A 4% solution for treatment of berry bushes is suitable.
- Fall plants are sprayed with a 7% solution.
The bark on young trees is not as thick as on older trees, therefore the solution used for their treatment must be less saturated. This is something to watch out for, especially if the garden is treated twice a season.
Benefits and disadvantages
This treatment has advantages and disadvantages like all others.
- It has a broad action;
- it is inexpensive;
- it poses little danger to humans when exposed because it is low-toxic (if the highly concentrated product gets on mucous membranes or skin, it should be simply washed off with a stream of water, and then there will be no damage);
- Highly effective against diseases that are fungal;
- It has an external effect, it does not get inside the plant.
The disadvantages include:
- is ineffective in the control of pests (you will need additional preparations for their complete elimination);
- it can be used only at the beginning of the spring period (before the opening of buds) and after the fall of leaves, the fact is that such a preparation can damage the leaf plates and young shoots;
- is quickly washed away by rain, after spraying it starts to work after a couple of hours, but the maximum effect is achieved only after 24 h, so if it is raining outside, it is necessary to spray the tree several times.
If the garden is not treated correctly with iron sulfate, this will have an extremely negative effect on its condition. It is therefore very important to carefully read the instructions for use that come with the product before treatment.
