What to do if plant leaves turn yellow in summer

Reasonable watering

Water is the source of growth for all things. Most of the reasons why plant leaves dry and turn yellow may be due to water.

The temperature is high in summer and water evaporates quickly. During the daily maintenance of flowers, if watering is not done in time, it is likely to cause the plants to wilt. At this time, you should pay attention to replenishing water to the plants in time; but if the plants have yellowing and withering leaves due to long-term lack of water, you must not water them suddenly in large quantities at this time. At this time, due to osmotic pressure, plasmolysis is likely to occur, causing cell damage, which will endanger the health of the plants.

As the old saying goes: Everything reaches its limit and then turns into its opposite. Excessive watering can cause water accumulation and root rot, which will manifest itself in the form of yellowing leaves on the plant.

Therefore, when caring for plants in summer, you must pay attention to watering them appropriately and reasonably.

In addition, the best time to water is in the morning or evening, and the water used for watering should be dried in the sun. If you use tap water directly, it is very likely that the water temperature will be too cold and stimulate the plants, causing damage to the plants.

Reasonable lighting

The second reason for yellowing leaves on plants in summer is light. Flowers are divided into two types of light habits: sun-loving and shade-loving. Many people have misunderstandings about this, thinking that sun-loving flowers should absorb more light, while shade-loving flowers should not be exposed to light. However, they do not know that this view is wrong.

The light intensity in summer is very high, and even many sun-loving plants cannot tolerate the scorching sun. Long-term direct sunlight will burn the leaf epidermis, causing the leaves to curl and dry up. To avoid the above situation, the lighting time should be adjusted in time, and attention should be paid to shading to prevent flowers from direct sunlight.

Although some plants like shade, photosynthesis is required for plant growth. Appropriate exposure to scattered light is very necessary for plant growth. Long-term lack of light will not only cause the plant to grow slowly and the leaves to be lifeless, but also easily induce diseases. At this time, we should fertilize the plants appropriately and adjust the light in time.

Reasonable fertilization

Many people will find that the plants are weak and the leaves have lost their green color during the maintenance process. At this time, it is very likely caused by the lack of nutrition of the plants. As long as the plants are fertilized reasonably and carefully maintained, this phenomenon will improve after a period of time.

If too much fertilizer is applied, "root burn" is likely to occur. You should know that the roots are important transmission organs of plants. Once the roots are damaged, it will naturally show up in the leaves and other places. Yellowing of leaves is one of them. In this situation, you should dilute it with clean water in time, or stop fertilizing immediately, and then continue fertilizing after a period of maintenance.

Pest control

When the yellowing leaves appear, you can check the leaves immediately to see if there are any insect pests on the plant. Once discovered, you can prune or manually expel them, or use pesticides if necessary.

If the yellowing of leaves is caused by disease, timely medication and sterilization should be carried out to ensure that the right medicine is used.

How about it? After listening to me talk so much, have you gained anything? In fact, no matter what the reason for the yellowing leaves is, it is caused by improper operation in our daily maintenance process. This requires us to treat every plant with care. Only in this way can the flowers feel the care of their owners and grow more vigorously to repay us!
