Every time I see ferrous sulfate, will think of junior high school chemistry teacher, there are always students write the wrong formula for ferrous sulfate, he was furious on the blackboard to emphasize is FeSO4-7H2O, but also bitterly ah. Thought out of school, will no longer come into contact with ferrous sulfate, I did not expect now home and bottled and bagged ferrous sulfate. Although ferrous sulfate is not a fertilizer, but in the process of raising flowers will be frequently used, which flowers need to use ferrous sulfate?

The role of ferrous sulfate in growing plants

As long as the mention of ferrous sulfate, our first reaction it is used to regulate the soil acidic and alkaline properties, and most of them are applicable to the soil in the north, especially the flowers born in the south, to the north, no matter whether it is planted in the ground or in pots, it is necessary to regulate the alkaline and saline soil to acidic soil or slightly acidic soil, so that flowers can grow normally, or else it will be yellow leaves, leaf drop, until it dries up and dies.

In addition, when the flower leaves appear yellow, while the leaf veins are still green, indicating that flowers have iron deficiency yellowing disease, that is, the lack of iron in the soil leads to yellowing of the leaves, this time, we should use ferrous sulfate solution to supplement the iron, and slowly flowers will return to green leaves.

Need to use ferrous sulfate flowers

Since ferrous sulfate can regulate the acidity of the soil, like slightly acidic or acidic soil flowers, cultivated in the north, certainly the first to adjust the soil properties, although the improvement of soil acidity of sulfur powder, aluminum sulfate, humus fertilizer, etc., but more commonly used is ferrous sulfate solution, although the time limit is short, but the effect is fast.

Family common like slightly acidic flowers are: milan, cyclamen, cinnabar, osmanthus, camellia, etc., like acidic soil flowers are: azalea, gardenia, jasmine, jasmine, camellia, hydrangea, colorful foliage grass, etc., of which gardenia iron-deficiency yellowness disease is very common, as long as the timely irrigation and watering of ferrous sulphate solution, and soon be able to recover.

Ferrous sulfate dosage and common method

Ferrous sulfate commonly used method is diluted with water to pour flowers potting soil, generally in accordance with the proportion of 1:1000 water, or proportion smaller can be, rather light do not thick it, a bite to eat not big fat.

Ferrous sulfate in the diluted, you can irrigate the roots, usually every 15 days ~ 20 days irrigation and watering 1 time, there is a lack of iron reaction, can be shortened to weekly irrigation and watering 1 time, such as flowers to return to normal, and then back to the normal watering cycle can be. Can also be diluted in the foliar spray, supplemental iron, spraying 1 ~ 2 times a month can be.

One more thing, large particles of ferrous sulfate before use to break into powder, easier to dissolve in water.

In summary, ferrous sulfate is suitable for flowers that like slightly acidic or acidic soil, regulating soil acidity, but also for flowers when iron-deficiency yellowing disease, supplemental iron use.
