How to use ferrous sulfate correctly for home gardening (how to use ferrous sulfate for the best effect)

Ferrous sulfate mainly contains iron, which is used in agriculture to regulate the pH value of soil and promote the formation of chlorophyll .

It is mainly used for some acid-loving plants and flowers, such as gardenia, azalea, jasmine and other flowers that have iron deficiency chlorosis, or the soil is alkaline, etc., and ferrous sulfate will be used. So how should ferrous sulfate be used, and what should be paid attention to when using it?

Root irrigation with ferrous sulfate solution

When we grow some flowers that like acid, we should often water them with some acidic fertilizer liquid, such as some decomposed organic fertilizer, or some fermented rice water, fruit peel water, etc., to prevent the plants from having yellow leaves due to iron deficiency.

Once flowers show yellow leaves due to iron deficiency, if the condition is serious, you should immediately repot and change the soil. If the symptoms are milder, you should supplement iron in time, which requires the use of ferrous sulfate.

Ferrous sulfate can be diluted into an aqueous solution at a ratio of 1:1000 and directly irrigated to the plant roots once every 8 to 10 days. Generally, 2 to 3 times can significantly improve the symptoms of yellow leaves.

Ferrous sulfate root irrigation precautions

When watering flowers with ferrous sulfate, you must control the concentration of the fertilizer and try to make the fertilizer solution thinner so that it is easier to absorb and utilize.

If the fertilizer solution is too concentrated, it will not only fail to improve the yellow leaves, but will cause root burn, leading to more yellow leaves and falling leaves, so it is very important to control the concentration.

Ferrous sulfate spray on leaves

In addition to directly adding water to the roots, ferrous sulfate can also be diluted and put into a spray bottle to spray the branches and leaves of the plant. After spraying on the leaves, the nutrients will be absorbed through the leaves, which can more directly supplement the iron element for the plant, and the effect is also very obvious.

Precautions for spraying ferrous sulfate on flowers

When spraying ferrous sulfate on the leaves of flowers, the concentration must be properly controlled. The ratio can also be adjusted to 1:1000.

However, the spraying time should be chosen during the noon time when the weather is clear. After spraying, you should pay attention to keeping the environment ventilated so that the solution can be more easily absorbed and utilized.

Because in rainy weather, after spraying, coupled with poor ventilation, the leaves will not dry for a long time and rot easily.
