Can ferrous sulfate powder be stirred in the soil of the osmanthus pot to adjust the pH of the soil?

Raise osmanthus to regularly give it to replenish the mixed water, this mixed water is to regulate the acidity, some flower friends will choose to use ferrous sulfate directly, but the effect of ferrous sulfate directly will be minimal, ferrous sulfate contains iron, and it is acidic, can regulate the soil, ensure that the soil is acidic, and the iron in it can be quickly absorbed by the osmanthus, there will be no yellowing of new leaves, because osmanthus is a flower in the south, its absorption of iron is relatively large, Ordinary potting soil is missing after it will cause yellow leaves, and in the north to raise osmanthus, we all know that the water quality is alkaline, the soil is alkaline, so it is not good to raise it, as long as the osmanthus is in the growing season, we regularly water him once a month with a mixed ferrous sulfate solution.

Find two catties of water, that is, 1000 ml of water, and then take a few drops of rice vinegar to drop into the water, and then add a level spoon of ferrous sulfate, that is, one gram of ferrous sulfate, stir them thoroughly, so that after stirring evenly, its color is light green, so that the prepared solution is an acidic aqueous solution, which contains iron elements, and it is acidic. We all know that ferrous sulfate will turn black-brown when exposed to the air, and it will become black-brown when mixed with water for 10 minutes and 8 minutes without use, which is oxidation, oxidized is trivalent iron, which cannot be absorbed, we only add some rice vinegar, citric acid and the like when blending, add a little bit on it, and then mix ferrous sulfate, it will not oxidize, and this liquid can be stored for a long time, and it can be used for watering every time, and there will be no oxidation and no absorption. It may not be effective after using it.

Actually, there is not so much trouble, I use rice water to drench flowers, rice water is acidic, which is of great help to the production of flowers.

OK. Soybeans and yogurt are rich in organic matter and are very good organic fertilizers after fermentation. Organic fertilizers are more nutritionally balanced than compound fertilizers. It can provide comprehensive nutrients to plants and is more suitable for plant growth.

Ferrous sulfate is a soluble iron-containing solution that plants are able to absorb. Prevent yellowing and improve soil pH.

The fermentation process of organic matter tends to give off an unpleasant taste, but when ferrous sulfate is mixed, the unpleasant taste is greatly reduced.

It should be noted that it must be mixed with water before it can be used to water the flowers, otherwise it is possible to burn the seedlings.

Try not to pour directly on the leaves, it is best to pour it into the soil.
