How to maintain the flowers after watering ferrous sulfate?

After watering the flowers with ferrous sulfate, put them in a cool and ventilated place to raise the flowers, do not contact the light first, and you can maintain and manage them normally after one day.

When watering ferrous sulfate, the leaves should be sprayed evenly as much as possible, which can reduce the yellow leaves and promote the yellow leaves to turn green. The time for pouring ferrous sulfate must be the most suitable in the evening, and after watering, it can be absorbed by the plant at night. If watering during the day, do not expose the plant to light after watering, otherwise it will burn the leaves and roots.

Flowers should add a little citric acid to the water before using ferrous sulfate, keep the water acidic, avoid the appearance of yellow leaves due to iron deficiency in flowers, and pay attention to the watering cycle.

When watering flowers with ferrous sulfate, try to spray the leaves evenly, which can reduce the yellow leaves, promote the yellow leaves to turn green, and after watering for 20 minutes, you should use water to dilute the ferrous sulfate in the soil.

It is necessary to water in time to dilute the ferrous sulfate in the soil as much as possible, so that the roots of the flower can absorb the ferrous sulfate and the leaves of the plant can become greener.

Freshly fertilized flowers and plants should be protected from direct sunlight and should not be used together with ammonia nitrogen fertilizers and fertilizers with calcium, magnesium, manganese, copper, etc., which can affect the iron complexes in ferrous sulphate and thus affect iron absorption.

Summary. After ferrous sulfate is mixed with water, it will quickly oxidize and become the same color as rust, and the oxidized ferrous sulfate water cannot play a regulating role, so the ferrous sulfate aqueous solution should be prepared and used now, and should not be stored for a long time.

It is precisely because ferrous sulfate is easy to have strong oxidizing properties, so ferrous sulfate is not suitable for foliar top dressing, because the ferrous sulfate remaining on the leaves is easy to oxidize quickly, and become rust-like residue on the leaves, forming unsightly scars, and it is difficult to remove.

How long does it take for ferrous sulfate to water flowers to see the effect.

The concentration is high for about a month, and the effect can be seen for about two or three months.

Ferrous sulphate is a commonly used acid fertilizer, and is often used to adjust the pH of the soil when cultivating acid-loving flowers.

The role of ferrous sulfate fertilizer, ferrous sulfate is an acid regulator to adjust the pH of the soil, and it is also an iron supplement, so ferrous sulfate is not a universal fertilizer, nor can it be used instead of other fertilizers.

Ferrous sulfate is not a panacea, but it is a fertilizer for acid-loving flowers to supplement iron and adjust soil pH, which is used in the cultivation of acid-loving flowers, and is generally used in combination with watering.

For example, the soil and water in the northern region are alkaline, and when breeding rhododendrons, gardenias and other acid-loving flowers, it is necessary to often add ferrous sulfate to the water to irrigate, and use the acidity of ferrous sulfate to neutralize the alkalinity of the soil, so that the potting soil is maintained at a weak or weakly acidic level, and at the same time supplement iron. The concentration of ferrous sulfate root irrigation should not be too high, and it is recommended to control the concentration at 800-1000 times of root irrigation, which is relatively safe.

After ferrous sulfate is mixed with water, it will quickly oxidize and become the same color as rust, and the oxidized ferrous sulfate water cannot play a regulating role, so the ferrous sulfate aqueous solution should be prepared and used now, and should not be stored for a long time. It is precisely because ferrous sulfate is easy to have strong oxidizing properties, so ferrous sulfate is not suitable for foliar top dressing, because the ferrous sulfate remaining on the leaves is easy to oxidize quickly, and become rust-like residue on the leaves, forming unsightly scars, and it is difficult to remove.

Correct use of ferrous sulfate for flower cultivation:

1. Not all flowers can be raised with ferrous sulfate.

When ferrous sulfate grows flowers, it can make the soil slightly acidic, so ferrous sulfate is only suitable for flowers that like acidic soil, such as jasmine, gardenia, pothos, bamboo, etc., but flowers that like alkaline soil can not be used.

2. Do not directly sprinkle ferrous sulfate powder in the basin.

Ferrous sulfate will only dissolve and produce iron after it is dissolved in water, and the iron at this time can be absorbed by flowers for their own growth, and if ferrous sulfate is directly sprinkled in the potting soil, it will not produce iron and has no effect on the growth of flowers. Therefore, you must remember to dissolve it in water and then pour it into potting soil.

3. Ferrous sulfate needs to be sealed, and it is now used and dispensed.

Ferrous sulfate should be sealed when it is used, and it should be sealed in time after it is used up and placed in a dry place. Many people may also know that if ferrous sulfate is exposed to the air or its solution is placed openly, it is easy to oxidize ferrous sulfate, and the oxidized ferrous sulfate will lose its effect when it is used to water flowers.

4. Ferrous sulfate solution has a better effect as foliar fertilizer.

After ferrous sulfate is dissolved in water, you can pour the solution into a watering can and spray the solution on the leaves, which can also make the flowers grow better, and the effect is better than pouring it in the potting soil. However, ferrous sulfate spray on the leaf surface is easy to be oxidized, and after oxidation, it cannot be absorbed by flowers, so to prevent this from happening, spray a little less each time.

Here's how:

1. Ferrous sulfate is usually prepared into a solution according to the method, because the aqueous solution of ferrous sulfate can be directly provided to flowers to absorb and utilize iron, and can reduce the alkalinity of the soil to make it acidic.

2. The potting soil is mixed with ferrous sulfate and dissolved into a concentration of ferrous sulfate solution of 5 grams to 7 grams per pot to irrigate the potting soil, but the soluble iron poured into the soil will be quickly fixed and become insoluble iron-containing compounds and fail.

3. In the peak season of flower growth, the ferrous sulfate is mixed with the fertilizer water that is cooked with organic fertilizer to prepare alum fertilizer water, and the effect is good if it is diluted 10-15 times. Ferrous sulfate is easily soluble in water, so it should be used with it, and should not be stored for a long time to prevent oxidation and failure.

How to use ferrous sulfate for watering flowers, are you really using the right method?

How do you water flowers with ferrous sulfate? The use method is explained in detail, and it is very effective for dealing with the yellowing of flowers and leaves!

Don't panic when the rhododendron is yellowed, and if you pour ferrous sulfate, the flowers will bloom more delicately.
