Which flowers are not suitable for watering ferrous sulfate, and what flowers cannot be watered with

Camellias, azaleas,GardeniasSuitable for pouringFerrous sulfate

1. Ferrous sulfate can make the soil acidic, so flowers that like acidic soil are suitable for watering ferrous sulfate, such as camellias, azaleas, gardenias, and hydrangeas.

Violet, etc., can also be used to irrigate flowers and plants with yellow leaf disease due to iron deficiency. Ferrous sulphate is only a supplement and cannot be used as the main fertilizer for irrigation, so it should be diluted before irrigation and should not be poured on the plants.

2. Ferrous sulfate can water hydrangea, because hydrangea can grow on acidic soil or alkaline soil, and its flowers are pink on alkaline soil.

3. Ferrous sulfate is a very commonly used acid fertilizer, and ferrous sulfate is often used to adjust the pH of the soil when breeding acid-loving flowers.

It is also an iron supplement, so ferrous sulfate is not a general-purpose fertilizer and cannot be used in place 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.

Ferrous sulfate can enhance the acidity of the soil, which is of great help to some flowers, so what flowers can not be watered with ferrous sulfate, in fact, moon flowers, cloves, forsythia, crape myrtle, acacia, ash, hibiscus flowers, pomegranate flowers, cacti, cactus, etc. are not suitable for watering ferrous sulfate, which will affect the normal growth of flowers, and may even cause flower death. In life, many flowers are suitable for watering ferrous sulfate, which can make the flowers more bright and beautiful, but you can't water ferrous sulfate for the moon flowers, the moon flowers like to grow in alkaline soil, and the ferrous sulfate will increase the acidity of the soil, which is not conducive to the growth of the moon flowers.

Flowers that cannot be watered with ferrous sulfate are:

1. Moon flowers.

The moon flower is suitable for growing in neutral to slightly alkaline soil, and can not be watered with ferrous sulfate, because ferrous sulfate can adjust the pH of the soil, making the soil slightly acidic, which is harmful to the growth of the moon flower.

2. Lilacs. Cloves belong to the myrtle family, it also likes to grow in alkaline soil, so it is not suitable for watering ferrous sulfate, usually we can dry the flowers of cloves, and then soak them in warm water for five minutes to drink, which has high medicinal value.

3. Pomegranate flowers.

Ferrous sulphate cannot irrigate pomegranate flowers, which are deciduous shrub plants with a height of 2-5 meters and a height of 7 meters, their flowers are red, with about 5-7 petals, and pomegranate flowers bear fruit in September-October every year.

4. Hibiscus flowers.

Hibiscus belongs to the family Malvaceae hibiscus, usually we can also call it malaria flower, trumpet flower, hibiscus flower and other names, if it is cultivated in alkaline soil, it will grow very fast, the flowers are bright and beautiful, if you water ferrous sulfate, it will make hibiscus grow slowly.

5. Crape myrtle. Crape myrtle should not grow in acidic soil, when cultivating crape myrtle, if it is watered with ferrous sulfate, it will cause the root system of the plant to rot and blacken, and the flowering period of crape myrtle is from June to September every year, and its flowers are purple or dark red.

Ferrous sulfate is suitable for watering jasmine, gardenia, pothos, bamboo, rhododendron, moon flower, rhododendron, camellia, Milan, spider plant, etc., mainly used as fertilizer for iron-deficient flowers.

Blue or green ferrous sulfate powder is often seen in farmers' markets, and the general ferrous sulfate contains 19-20 iron, sulfur, which is a very good fertilizer. Regular use of acid-loving plants can prevent the occurrence of yellowing. Because iron is necessary for the formation of chlorophyll in plants, when plants are deficient in iron, the formation of chlorophyll is hindered, which will lead to green deficiency in plants, and the leaves will turn yellowish.

The aqueous solution of ferrous sulphate can directly provide iron that can be absorbed and utilized by plants, and at the same time can reduce the alkalinity of the soil.

In fact, in the soil of our north, there is generally no lack of iron, and in alkaline soil, iron becomes insoluble and cannot be absorbed by flowers. Ferrous sulfate will only dissolve and produce iron after it is dissolved in water, and if ferrous sulfate is sprinkled directly in the potting soil, it will not produce iron and has no effect on the growth of flowers to supplement iron. Therefore, when using ferrous sulfate fertilizer, do not water it into the soil, but spray it on the leaves, which are more easily absorbed by the leaves.

Ferrous sulfate should be sealed when it is used, and it should be sealed in time after it is used up.

There are many flowers and plants that cannot be watered with ferrous sulfate.

For example, pomegranate flowers, hibiscus flowers.

Ash, cactus, cactus.

Moon, crape myrtle, hibiscus, cloves, forsythia.

These plants all prefer alkaline soils. If ferrous sulphate is watered, the soil becomes more acidic, which can hinder growth. During the cultivation period, the soil should be slightly alkaline, and the nutrients should be sufficient and the light should be suitable, so that it can grow better and flower.

Extended information: 1. Suitable soil: Soil is prepared according to the habits of flowers and plants, which generally need to be soft, breathable and fertile.

2. Sufficient light: usually bask in the sun, and the flowers that are not resistant to sunlight should be blocked from strong light in time, and should not be placed in the shade for a long time, otherwise it is easy to grow.

3. Suitable temperature: provide a suitable temperature environment according to habits.

4. Appropriate amount of watering: frequent watering for those who like moisture, and less watering for those who are drought tolerant.

5. Reasonable topdressing: use thin fertilizer to apply topdressing frequently.

First, the soil is suitable.

When cultivating flowers and plants, it is necessary to prepare suitable soil according to their growth habits, and most flowers prefer soft, breathable and fertile substrates. However, the pH of the soil.

There are different requirements, if it is acid-like, acidic soil is prepared. If you like alkali, prepare alkaline soil.

2. Sufficient light.

Flowers and plants generally like light, and sufficient light should be provided during the maintenance period. Some plants do not have to worry about the scorching sun in summer, and they can be exposed to the sun, and the more sunlight they have, the more vigorous they will grow. Some plants are afraid of the scorching sun, so they need to block it during the bright light phase in summer.

If left in the shade for a long time, the flowers are easy to grow, which will affect flowering.

3. The temperature is suitable.

Flowering plants need to be kept at a suitable temperature, most plants prefer a warm environment, preferably between 15-25. Some plants have a certain degree of cold tolerance, and they can also bloom in winter, so they do not need to deliberately control the temperature to keep warm. Some plants have poor cold tolerance and can only be potted in cold areas.

After winter, you need to move indoors for wintering, otherwise you will be prone to frostbite.

Fourth, appropriate watering.

Some flowers and plants are drought tolerant, some prefer a humid environment, and the number of watering should be changed according to their respective habits to ensure that there is sufficient water**, so that they will grow vigorously.

Fifth, reasonable top dressing.

Flower plants consume a lot of nutrients during the growth and flowering period, and they need to be topdressed in time during the maintenance period. It is recommended to apply thin fertilizer frequently, which can better absorb nutrients and avoid fertilizer damage.
