Raising flowers use ferrous sulfate, the method should be "reliable", otherwise it will only be harmful and useless!
Northern flowers are easy to have problems, because now many flowers on the market like acidity, northern water quality alkaline, soil alkaline, a lot of southern flowers we can not raise, such as our rhododendron, jasmine, gardenia, including our raised Junzi orchid and the like, are like acidic soil, so we must regularly use ferrous sulfate when we maintain it, how should ferrous sulfate be used? How should I maintain it after use? Today Xiao Qi will tell you about it.
Ferrous sulfate it is a kind of supplementary iron element, adjust the soil acidic fertilizer, we must pay attention to the concentration is not high when we use it, generally used, the concentration is about 1:1000 on it, with water directly dissolved, if you have citric acid or ferrous sulfate companion or the like, we can add a little appropriately to ensure that we mix good ferrous sulfate does not appear to oxidize.
Because ferrous sulfate if you do not add other things, dissolved after the rapid change to brown, this is that it has been oxidized, oxidized ferrous sulfate can not be absorbed by plants, must be mixed after the watering, after about 20 minutes after watering to the flowers to water a water, must be watered thoroughly, so as to be able to ensure that there is no problem. If we have rice vinegar on hand, if we have ferrous semi-aluminum sulfate, we can add a little appropriately, so as to ensure that the iron element of ferrous sulfate is divalent iron, which will not oxidize, and when it is poured, it can be retained for a long time in the potting soil, so that the root system can continue to absorb.
This is the method of use, ferrous sulfate do not water too frequently, because its absorption of iron is not very large, if there is too much in the potting soil, it will inhibit its growth, the frequency of use is guaranteed to be used once in 1 to 2 months, according to the growth of plants to choose, such as when the plant grows very fast, we give him a month to use, when he grows slower, we can give him a time in two months, so that there is no problem.
The best way to use ferrous sulfate is to water into the potting soil, try not to spray on the leaves, because if the leaves are sprayed, it will evaporate through the light and moisture, it will leave some rust color on the leaves, then it will be very ugly, and it is not easy to clean, directly poured into the potting soil, absorbed by the roots, and then supplied to the entire plant to grow and regulate, so that there will be no problems.
If you are in the north, raising acid-loving plants, if your water quality is alkaline, ferrous sulfate must be used regularly, if there is no ferrous sulfate on hand, we can also use chelated iron, you can also use alum fertilizer water to water, but also can play a certain role.
