Which Plants Need to Supplement Ferrous Sulfate
Ferrous sulfate is suitable for浇灌 gardenias, milias, Chinese roses, azaleas, jasmines, etc. It is an inorganic salt without odor. Phosphate iron is rich in iron elements and can supplement iron for flowers, preventing chlorosis. However, ferrous sulfate makes the soil slightly acidic, and can only be watered on flowers that grow well in acidic soil.
Ferrous sulfate is an inorganic salt without odor, commonly used to water flowers for healthy growth. Some flowers are suitable for it, while others are not. What flowers is ferrous sulfate suitable for? How to water for better results? Let's discuss this next.
What Flowers Is Ferrous Sulfate Suitable for
Not all plants need to use ferrous sulfate. It is mainly used for southern foliage plants grown in the north to adjust soil pH and increase soil iron content.
For example, iron trees, azaleas, camellias, osmanthus, hanging orchids, poinsettias, jasmines, gardenias, and other foliage plants can all use ferrous sulfate.
Plants lacking iron can also use ferrous sulfate, with specific symptoms of iron deficiency being yellowing of new leaves and yellowing of veins in old leaves. If these conditions are met, it can be identified as iron deficiency.
However, ferrous sulfate makes the soil slightly acidic, and can only be watered on flowers that grow well in acidic soil.

How to Water Flowers with Ferrous Sulfate for Better Results
1. Watering Application
Before using ferrous sulfate, you should first understand the plants you are growing. If they are acid-loving plants like azaleas and milias, you can use ferrous sulfate. It can supplement iron elements for the plants and also improve soil acidity.
If the plants prefer alkaline soil, do not use ferrous sulfate to avoid reverse effects.
Ferrous sulfate is a fine powder containing iron elements, which can supplement some damage caused by iron deficiency in plants and also change soil acidity.
Generally, the purity of ferrous sulfate sold on the market is around 95%, regardless of packaging size. The usual dilution concentration for watering is about 1:1000, which means 1 gram of ferrous sulfate mixed with 1000 milliliters of water.
【Use as a Solution】
The most common way to use ferrous sulfate is to mix it with water to form a solution and then water the flowers. Plants will absorb the iron directly from the soil and also improve the soil's acidity.
【Frequency of Use Should Be Noticed】
Ferrous sulfate can be used to water flowers, but the frequency of use should not be too high. Long-term use can lead to overly acidic soil and also cause soil compaction.
There are generally two situations for using ferrous sulfate, one is diluting it with water for watering. Specifically, mix 1 gram of ferrous sulfate with 1000 milliliters of water, dilute it, and then water the potting soil. Use it once every 15 days or so.
After using it consecutively for two times, take a short break before continuing. Except for very acid-loving plants, slightly acidic plants should not use ferrous sulfate for an extended period.
2. Mixing with Soil
The second situation is direct mixing with soil. For acid-loving plants, when repotting or changing soil, a small amount of ferrous sulfate can be mixed with the potting soil, stirred evenly, and then used for repotting.
Note that the content of ferrous sulfate should not be too high. Depending on the size of the potting soil, use 2 grams as a guideline. For larger pots, a bit more can be used, and for smaller pots, reduce accordingly.
The Functions of Ferrous Sulfate
1. Ferrous sulfate contains sulfur and iron elements, which can provide essential nutrients for plants during growth.
2. The iron in ferrous sulfate can enhance the absorption of nitrogen, phosphorus, and other elements by flowers and regulate the plant's oxidation-reduction process, promoting the absorption of various elements.
3. Ferrous sulfate can prevent chlorosis, avoid leaf yellowing and shedding; it can also prevent rice blast disease, chlorosis, and (T-J) disease.
4. Ferrous sulfate is acidic and can neutralize the alkalinity in the soil, lowering the soil pH and improving the soil's acidity, which is beneficial for plant growth.
5. It can promote the formation of chlorophyll and enhance the photosynthesis of flowers.
