What if the flowers and leaves turn yellow?

There are many reasons why flowers and leaves turn yellow, and we should take different methods according to different reasons.

1. Illumination: direct sunlight can easily lead to burning and scorching of leaves, yellowing and drying of leaf edges and tips, and maculae in direct light. On the other hand, the lack of light for a long time can easily lead to poor growth and soften the leaves.

Methods: cut off the burnt yellow and dry leaves, put them in a cool place, and slowly wait for recovery. Those who lack light for a long time need to move it to a place with light.

2. Moisture: when the plant lacks moisture, the old leaves will first turn yellow, then start yellowing from the top to the bottom, and wither and yellowing from the edge of the leaves. Stagnant water in the basin can easily lead to plant root decay, affecting absorption, resulting in yellowing of leaves.

Methods: if you are short of water, you should replenish water in time, avoid high temperature evaporation at this time, and wait for the plant to recover; if you pour too much water, put the plant in a place with sufficient ventilation and light, and let the water evaporate.

3. Iron deficiency: the plant iron deficiency showed that the mesophyll was yellow and gradually formed a network, which had an obvious effect on the young leaves.

Methods: it can be diluted with ferrous sulfate with water, and then sprayed on the yellowing leaves.

4. Fertilization: in the process of flower cultivation, plants lack nitrogen, phosphorus and potassium fertilizer, so they will turn yellow from the old leaves, and then the new leaves will turn yellow. Excessive application of fertilizer can also lead to yellowing of plants due to overnutrition.

Methods: appropriate amount of rarefied mature fertilizer or compound fertilizer was applied to meet the demand of nitrogen, phosphorus and potassium in the process of plant growth. If too much is applied, it should be diluted or replanted.

5. Soil: the soil is not suitable for plants, and there will be yellow leaves.

Methods: the pH was improved or replanted.

6, temperature and humidity: the growth environment is too dry or high temperature leads to large evaporation, which is easy to make the leaves yellowing, low-temperature and cold-resistant plants are easy to frostbite, leaves yellowing and withering.

Methods: in the high temperature environment, spray water near the plant to maintain the surrounding humidity; pay attention to sun protection and cooling in summer and keep warm in winter.

To raise a plant, it is necessary to adjust various growth conditions according to its variety preferences. Only in this way can a good plant be cultivated. At the same time, when there are adverse symptoms, we should prescribe the right medicine in time.
