Which plants need iron supplementation
If you want to know which plants need iron supplementation and a brief introduction to three plants that can prevent yellow leaves by supplementing iron, let's take a look together.
The biggest worry for indoor gardening is the yellowing of plant leaves. Once the leaves show signs of yellowing, it's difficult to know where to start or how to solve the problem, especially for新手 gardeners. When faced with yellowing leaves at home, they can only look on helplessly, wanting to deal with it but not knowing how to resolve it.
Plant leaves turn yellow due to a variety of factors, the most common being overly wet soil,积水, and poor soil aeration, which can cause slight yellowing of the leaves. As long as watering is controlled in everyday care, a small amount of leaf yellowing is not a major issue, and it's sufficient to remove the yellow leaves.
To prevent the yellowing of plant leaves, it's necessary to supplement trace elements to the plants when needed. Potted flowers consume the most nutrients during growth. After a plant has been grown for two to three years, the soil in the pot basically contains no nutrients. You either need to repot the plant or supplement it with trace elements.
Plants' primary need for trace elements is iron. Sometimes, the leaves of the plants in our homes show a widespread light green color, which is caused by a lack of iron. Osmanthus is a common example. It has a large number of leaves and a high bloom rate, requiring a significant amount of iron, so its leaves tend to yellow frequently.
Which plants need iron supplementation
Osmanthus: The demand for trace elements in osmanthus is among the highest in the plant world. This is because it blooms in autumn and produces a large number of flowers, densely covering the branches with petals. It consumes a lot of nutrients during the blooming period. For potted osmanthus over two years old, it's necessary to supplement with ferrous sulfate. It can be dissolved in water and watered directly into the soil according to the correct proportions.
Gardenia: Gardenias, from the moment they are brought home, require the preparation of ferrous sulfate. Gardenias are typical southern plants that need acidic soil to grow normally. Their leaves are very glossy green, and they look unattractive when they turn yellow. Therefore, it's essential to use ferrous sulfate to acidify the soil and supplement trace elements.
Monstera: Monstera is also one of the most common green plants in home gardening and is very easy to care for among ornamental plants. It can also be grown in the north. To keep its leaves green for a long time, in addition to fertilizing, ferrous sulfate is also an essential nutrient. For plants with a large number of leaves and that do not shed leaves all year round, trace elements should also be used during fertilization.
I have all these three plants at home, and these are the experiences I have accumulated during the maintenance process. Gardenias and osmanthus both need to be supplemented with iron every autumn. Gardenias require acidic soil for growth, and osmanthus requires iron. Having ferrous sulfate at home is key to indoor gardening.
