Ground-grown flowers and plants use less ferrous sulfate because their roots "look for" the iron they need from the soil. Potted flowers and grasses are prone to iron deficiency yellow leaves, which affects plant growth. For example, the hanging orchids, geraniums, camellias, jasmine, gardenias, bougainvillea, moon seasons, etc., which we see every day, may appear iron deficiency yellow leaves in the summer. When iron deficiency yellow leaves appear in flowers and plants, the use of ferrous sulfate has a good effect. Some flower friends say that the use of ferrous sulfate for flowers and plants has no effect, that is, you are not used right, otherwise there will be no such thing as ferrous sulfate. Flowers and grass yellow leaves with ferrous sulfate, 4 "key points" do not know, spend money in vain.
Some flower lovers have heard that ferrous sulfate can treat yellow leaves of flowers and plants, and no matter what the cause of yellow leaves, ferrous sulfate is used. This use not only can not treat yellow leaves, but also may lead to rapid death of flowers and plants. Ferrous sulfate can only treat iron deficiency yellow leaves, and is ineffective against arid yellow leaves, rotten root yellow leaves, and diseases and insect pest yellow leaves.
How to determine whether the yellow leaves of flowers and plants are iron deficiency yellow leaves? Mainly look at the location where the yellow leaves appear. The iron-deficient yellow leaves of flowers and plants first appear at the top of the branches, that is, the new leaves turn yellow and the old leaves are normal. And dry yellow, rotten root yellow leaves, diseases and insect pests yellow leaves, most of them are the bottom of the old leaves yellow first, the new leaves are nothing. In addition, flowers and plants with clear leaf veins, when iron deficiency yellow leaves appear, are often yellow and white, and the leaf veins are still emerald green.
After the ferrous sulfate is dissolved, it can be sprayed foliarly or irrigated with roots. Some flowerers have iron deficiency yellow leaves in their flowers and plants, and the effect of foliar spraying of ferrous sulfate solution is not obvious at this time. Because when the flowers and plants appear iron-deficient yellow leaves, the potting soil has alkalized. Soil alkalinization affects the absorption of iron ions and also affects the growth of flowers and plants. Foliar spraying of ferrous sulfate can only absorb iron ions, and does not change the acidity and alkalinity of the soil, and the yellow leaves do not turn green so quickly.
If you want to make the leaves of flowers and grasses that already have iron deficiency yellow leaves green, you can irrigate the roots with ferrous sulfate solution when the pot soil is dry, and supplement iron ions while changing the acidity and alkalinity of the soil. If the yellow leaves are already more and more serious, you can irrigate the roots and foliar sprays at the same time, use them every 10 days or so, and use them 3 times in a row, and the situation will improve significantly.
When raising some flowers and plants that are prone to iron deficiency yellow leaves, regular use of ferrous sulfate has a good preventive effect. If the prevention work is done well, there will be no worries about yellow leaves. Because when the flowers and grasses appear yellow leaves, it has affected the growth of the plant. For example, when raising jasmine, rhododendron, gardenia, camellia and other flowers and plants, the use of ferrous sulfate solution once a month can effectively prevent the appearance of iron deficiency yellow leaves. Especially in the area where the water quality is alkaline, it is necessary to rationally use ferrous sulfate.
When using ferrous sulfate solution to prevent yellow leaves of flowers and plants, it can be sprayed foliarly or irrigated with roots. If you feel that it is inconvenient to irrigate the roots, or you will worry about problems, then foliar spraying can quickly replenish iron elements and make the leaves of flowers and grasses emerald green and shiny.
The use of ferrous sulfate for flowers and plants is not the more you use the better. Overdose can also have side effects, causing the leaves of flowers and plants to turn yellow and dry or the whole plant to die. Some flower lovers have heard that ferrous sulfate can prevent and treat yellow leaves of flowers and plants, regardless of whether their flowers and plants are iron deficient, whether there is a risk of iron deficiency, they buy a can to come back and use it. As a result, the flower grassland originally did not have yellow leaves, and yellow leaves appeared when used. These yellow leaves are not caused by iron deficiency, but by improper use of ferrous sulfate.
When using ferrous sulfate, be sure to use it quantitatively according to the instructions, and don't feel that it is okay to use more than you want. Sometimes using a little more may affect the growth of flowers and plants. In addition, the best way to use ferrous sulfate is to mix it with organic fertilizer to make fertilizer alum water, which can not only improve fertilizer efficiency, but also supplement iron well, so that flowers and plants grow healthily.
