How to use ferrous sulfate to grow flowers correctly

In fact, ferrous sulfate is suitable for potted flowers and trees that prefer acidic soil, especially potted flowers and trees in the south such as azalea, gardenia, camellia, etc.

Its main function is to improve the pH value of the soil in the flowerpot and avoid the phenomenon of yellowing, weakness, or even scorching and falling off of leaves of flowers and trees due to the weakening of the acidity in the soil.

The correct way to use ferrous sulfate to grow flowers and trees is to apply ferrous sulfate reasonably according to the pH value of the soil of the potted flowers and trees. Generally speaking, when the leaves of acid-loving flowers turn yellow, or the loam of the potted flowers and trees is alkaline .

When symptoms such as alkali reversion, compaction, and airtightness appear, diluted ferrous sulfate solution can be used for watering.

The dilution ratio is : add 1% ferrous sulfate into the diluted fertilizer, stir evenly and pour it into the potting soil, about 2 to 3 times a month. Its effect is similar to alum fertilizer water.

During the vigorous growth period of acid-loving flowers and trees, apply diluted ferrous sulfate solution once every 10 to 15 days. The dilution ratio should be 0.5% to 1%. Avoid applying too concentrated or excessive solution, which will affect the growth and development of flowers and trees.

After applying the diluted ferrous sulfate solution, the yellow leaves of flowers and trees will gradually turn green. This is one of the effective ways to properly apply ferrous sulfate to grow acid-loving trees.

Of course, other methods can also be used to improve the problems of yellowing and falling leaves of flowers and plants.

For example, adding a few drops of salt-free rice vinegar to the water every time you water it, or using diluted lemonade to water flowers and trees, is also a good way to improve the pH value of the soil .

However, for flowers and trees with dark green leaves that do not like acidic soil, as well as flowers and trees such as roses and pomegranates that prefer neutral soil, there is no need to use ferrous sulfate for watering frequently to prevent physiological effects on the flowers and trees.
