The use of ferrous sulfate in horticulture: It is generally suitable for plants that prefer acidic soil, especially potted camellias, azaleas, and gardenias. Leaf yellowing or even browning due to reduced acidity in the potting soil can be addressed by applying ferrous sulfate. Ferrous sulfate is an inorganic chemical fertilizer that promotes the synthesis of chlorophyll in plants. However, it should not be applied frequently; only four to five times a year is allowed, as frequent application can affect root growth. If there are any application methods, there are two: one is application at the roots. Dissolve ferrous sulfate in fertilizer solution or clean water and apply it directly to the plants; the concentration of the solution should be maintained at 1-2%. Alternatively, ferrous sulfate can also be placed directly on the topsoil in the flower pot, where it will gradually be absorbed as watering occurs. For a 20cm pot, 1g is sufficient for the first application. The second is foliar fertilization. Ferrous sulfate can be dissolved in water and used for foliar fertilization with a sprayer; it is absorbed through the stomata on the leaves, thereby exerting its fertilizing effect directly. When spraying, it is best to do so in the early morning or late evening on a calm day with no wind or rain. The usage rate can be 0.1%-0.3%; it can also be used in combination with urea, which yields better results. A chemical compound called ferric citrate has the same effects as ferrous sulfate; both of these compounds are available in chemical stores, and their preparation and application methods are identical. We are all engaged in chemical production or related work; laboratories generally have ferrous sulfate, and using it can help ensure that potted flowers survive, preventing the situation where they bloom heavily in the first year, bloom in the second year, do not bloom in the third year, and are left with just empty pots by the fourth year. 】
