Which plants need to supplement ferrous sulfate?

Gardenia, rhododendron, jasmine, orchid, radish, asparagus, tortoise shell bamboo, violet, colored grass, hyacinthus orientalis and other plants need to be supplemented with ferrous sulfate.

When ferrous sulfate is put into the soil, it can neutralize the soil. For plants that like to grow in acidic soil, when the soil is too alkaline, it will affect the normal growth and nutrient absorption of plants. At this time, ferrous sulfate will be diluted and poured into the soil to change the pH of the soil.

Flowers containing ferrous phosphate should not be used, such as rose, clove, forsythia, crape myrtle, acacia and pomegranate, because these flowers will like slightly alkaline soil, so ferrous sulfate is not needed.

The following plants need to add ferrous sulfate:

Gardenia: Gardenia is a common southern flower, which likes acidity and is suitable for supplementing ferrous sulfate.

Rhododendron: Rhododendron is also a kind of acid-loving flower. Supplementing ferrous sulfate can improve the acidity and alkalinity of soil and lay a foundation for growth.

Jasmine: Reasonable supplementation of ferrous sulfate during the growth of Jasmine is helpful to its growth.

Milan: Milan also needs to supplement ferrous sulfate, but the dosage should not be too large.

The main function of ferrous sulfate is to change the pH of soil, so flowers that like acidic soil are very suitable for watering with ferrous sulfate, such as camellia, rhododendron, gardenia, hydrangea and violet. , are very suitable for watering with ferrous sulfate. Ferrous sulfate is rich in acidity, and the diluted ferrous sulfate can reduce the alkalinity in the soil.

In addition, it should be noted that when ferrous phosphate is used, only flowers can be irrigated, and ferrous phosphate cannot be directly sprayed on roots or branches and leaves.
