The recently cultivated flowers suddenly began to wither, and the leaves became very dry, all yellow, and some were still red. What's the matter? Is there something missing?

Too much water and water can easily lead to poor root respiration and serious root death, which affects plant water absorption. Of course, too little water is easy to wither.

Light, light will turn yellow if it is not long enough, and the sun will turn yellow. Some flowers wither easily if the temperature is too high.

If it is in full bloom, a lot of phosphorus and potassium fertilizer are needed in full bloom. If the soil is not enough, potassium will be transferred from the old leaves to the flowers, so the old leaves will turn yellow first, and if they are not enough, they will wither.

If the fertilizer is too heavy, the leaves will burn and wither.

The increase of alkalinity of basin soil affects the absorption of nitrogen and iron by roots, leading to iron deficiency and hypoxia, chlorophyll deficiency and yellowing.
