The purpose of fertilizing the flower is to make it grow more prosperous, but improper operation is counterproductive. No flower friend asked me that the cuckoo's leaves blackened after using ferrous sulfate. What should I do in this case? Today, let's analyze the reason.

This flower friend's pot of rhododendron obviously uses too much fertilizer and burns flowers. Rhododendron is an acidic flower. It is understandable to supplement ferrous sulfate once a month. However, we must apply thin fertilizer frequently, and we must grow flowers and fertilize. We must remember this rule. What should we do if the cuckoo blackens in a large area now?

Change the basin soil, replace these soils with too high ferrous sulfate content, because, as a trace element, ferrous sulfate can occupy a little bit in the basin soil. If there are too many elements in the soil, the black leaves can only become more and more serious. In a few days, the basin soil can be replaced, the roots can be washed with clean water several times, the remaining ferrous sulfate will be washed away, and then some nutrients will be balanced. Loose and breathable nutritious soil, then, cut off these blackened leaves, trim the diseased branches to keep the soil slightly wet, and put them in a place of ventilated and scattered light, so that the plants can be bagged and moisturized, and there are a few holes in the bag for ventilation, so that it is possible to recover.

Let's talk about the use of ferrous sulfate as a chemical fertilizer for the treatment of chlorosis. The demand in the soil is very small. For some southern flowers, it is enough to apply it once a month, and the maximum amount is 1: 1000. For example, our mineral water bottle is 500 grams of water, half a gram of ferrous sulfate is enough, not necessarily every month, but also at intervals. After we buy a bag of ferrous sulfate, it will be enough to water it for one year, and then pour it with clear water every ten minutes, so that the whole flowerpot is filled with this trace element, and the root system of the flower will be evenly absorbed and grow better.
