Ferrous sulfate as fertilizer can supply a lot of iron to plants and flowers (the iron content of ferrous sulfate is 19% - 20%), but if the application method is improper, it will lead to excessive iron fertilizer or burn flowers and plants poisoning. So how to water and fertilize the flowers is the best way? Lvyuan Environment Group Co.,Limited tells you the following methods:

1. The ferrous sulfate solution is prepared according to the method, because the ferrous sulfate solution can be directly provided to the flowers to absorb and utilize the iron, and can reduce the alkalinity of the soil, making it acidic reaction.

2. The pot soil was irrigated by adding ferrous sulfate into the pot soil, which was dissolved into 0.2% - 0.5% ferrous sulfate solution of 5g-7g per pot. However, the soluble iron in the pot soil would soon become insoluble iron compounds and become invalid. In order to prevent iron from being immobilized, the method of spraying 0.2%-0.3% ferrous sulfate solution onto the leaf surface is better than irrigation. However, due to the very small mobility of iron in flower bodies, spraying the iron solution to the green leaves only after spraying, so it is necessary to spray the leaves continuously for 2-3 times to achieve better results.

3. In the peak growing season of flowers, the effect is good when ferrous sulfate is mixed with organic fertilizer and water to make alum fertilizer and water diluted 10-15 times. It should also be noted that ferrous sulfate should not be spread on the surface of basin soil, and should be applied and mixed on the spot, otherwise it is easy to be oxidized into high valent iron and become invalid.

Precautions for ferrous sulfate fertilization: when applying ferrous sulfate in highly alkaline basin soil or soil, potassium fertilizer can promote the movement of iron ions in plants, but it should not be applied together with ammonia fertilizer and fertilizer containing calcium, magnesium, manganese, copper and other elements, because these elements will have antagonistic effect on iron and counteract the effect of iron ions. After application, try to avoid direct sunlight, which will cause iron ion precipitation in the solution and affect the effect.
