Which flowers can't be watered with ferrous sulfate?

Can't pour ferrous sulfate: Chinese rose, clove, forsythia, crape myrtle, acacia, ash, Dendrocalamus, pomegranate flower.

Ferrous sulfate is not a fertilizer for growing flowers. Ferrous sulfate is a kind of chemical solvent. Simple analogy is equivalent to a functional drink for people to drink, which can only increase energy, and is not a formal fertilizer.

Nitrogen, phosphorus and potassium compound fertilizer is fertilizer, so ferrous sulfate can't be used often. If it is the "staple food" of plants, it will make plants intolerant, the soil will be excessively acidified and the leaves will wither.

The role of ferrous sulfate:

1, Control of Verticillium Wilt

Literally, we can know that ferrous sulfate contains iron and plays a role in supplementing iron. If the leaves of plants are yellow and show iron deficiency, ferrous sulfate can be used to prevent and treat chlorosis.

2. Water regulator

Ferrous sulfate plays an acidic role. Many plants like acidic soil, and most of the soil in the north is alkaline, so ferrous sulfate can be used appropriately to improve the pH of the soil.

5. Because of the acidity of ferrous sulfate, ferrous sulfate can improve the acid-base balance of soil, and transform ferrous iron in high alkaline soil into ferric iron, which exists in soil for a long time and reduces its alkalinity, especially for calcareous soil.
