Teach you to correctly use ferrous sulfate that is loved by sour flowers such as cuckoo, jasmine, gardenia, camellia and so on.

On various learning and communication platforms, friends who like to grow flowers always hear such special words as "sour flowers" and "ferrous sulfate". Many flower lovers cannot correctly understand their meaning, which leads to blind imitation, which not only does not play a good role in flower cultivation, but also hinders the growth of flowers. Today we will take an in-depth analysis of the correct meaning of these two words and how to use ferrous sulfate correctly.

Acid-loving flowers, that is, acid-loving soil, can grow well in an acidic environment, or flowers that can reproduce normally. They are also plants, why do some of them like acid so much? This has a lot to do with their original growing environment. Such as rhododendron, gardenia, jasmine, camellia, Milan and other flowering plants, most of them come from the south of our country. As we all know, due to regional differences and different climatic conditions in the north and south of China, the soil in the south is sour and the soil in the north is alkaline. These sour flowers from the south come to the north through various modes of transportation, which is bound to be unsuitable for the alkaline growth environment of the north, so there will be the phenomenon of bud disappearance and yellow leaf wilting. In addition, the water quality in the north is also alkaline, and if it is not improved, it will aggravate the wilting or death of flowers, and ferrous sulfate can effectively improve the alkaline phenomenon of soil and water quality, and even if these flowers grow normally in the south, can not do without the supplement of iron. Therefore, we suggest that we put some ferrous sulfate when watering sour flowers.

Ferrous sulfate is a soil improver, not a fertilizer. Iron in ferrous sulfate is one of the essential elements for plant growth and the formation of chlorophyll. When plants are deficient in iron, there will be chlorosis of leaves, short growth of plants, yellow leaf disease, scorched leaves and buds, and so on.

Although ferrous sulfate can regulate soil acidity and alkalinity, it should not be overused. Such as rhododendron, jasmine, gardenia, camellia, Milan, kumquat, magnolia and other flowering plants, and some acid-loving foliage plants such as iron tree, tortoise back bamboo, rubber tree, Luohan pine and so on, most of them prefer slightly acidic soil rather than strong acid. excessive use of soil to become strong acid is bad for plant growth. It is generally recommended that when watering these plants, in the peak period of plant growth, using ferrous sulfate solution of 1RU 2000 once a month can play a good role in soil improvement.

Ferrous sulfate is a light green crystal and is easily oxidized in the air, so tighten the mouth of the bottle after each use. If you find that the color is yellow, it means it has gone bad, and stop using it immediately. In addition, ferrous sulfate and dung, cake fertilizer and water are arranged according to the ratio of 1: 3 to 5: 100, put into an airtight plastic container, and become a black-green liquid after full fermentation, that is, alum fertilizer water. After dilution, it is used to water these acid-loving flowers, which not only replenishes the nutrients to the flowers, but also can quickly alleviate the chlorosis caused by soil alkali or iron deficiency.
