What causes the yellowing and drying of plant leaves?
This article provides information on why plant leaves turn yellow and dry up, as well as the reasons behind yellowing and drying leaves, with the following details:
Inappropriate environment, high or low temperatures can cause the plant to have yellow leaves. In summer, when temperatures are too high, it is necessary to frequently spray water to cool down, and in winter, measures should be taken to keep warm; improper watering and fertilizing can also cause yellow leaves in the plant. Later on, it is necessary to wait until the soil is dry before watering and strictly control the amount of fertilizer applied; unsuitable soil, soil compaction can lead to poor growth in the plant, and it is necessary to loosen the soil in a timely manner.
1. Inappropriate Environment
In the process of caring for flowering plants, if the temperature of the care environment is too high or the plant is exposed to low temperatures and frost damage, it will affect the normal growth of the plant, causing the leaves to turn yellow and dry. Therefore, in the summer when the temperature is too high, it is necessary to spray water around the leaves to cool down, and in winter, the plant can be moved to a warm room, keeping the room temperature above 10℃.
2. Improper Water and Fertilizer Application
In the process of caring for plants, it is necessary to manage water and fertilizer properly. If there is a lack of water or nutrients, the roots will not be able to absorb water and fertilizer normally, causing the leaves to turn yellow and dry. If too much water and fertilizer are applied, it will burden the roots, affecting normal absorption and causing the leaves to become burned and dry. In later management, it is necessary to wait until the soil is dry before watering and strictly control the amount of fertilizer applied.
3. Soil Compaction
In the process of caring for plants, it is necessary to adjust the pH of the soil according to the plant's growth habits. If acid-loving plants grow in alkaline soil for a long time, it will cause the plant to have yellow leaves and dry up. It is necessary to pour a diluted solution of ferrous sulfate into the soil to adjust the soil's pH.
4. Excessive Sun Exposure
Flowering plants thrive in a gentle environment. If exposed to excessive sunlight, the leaves will turn yellow and dry. Therefore, in the summer when sunlight is too strong, it is necessary to set up a layer of shade net above to weaken the intensity of the light. It is also necessary to frequently spray water around the leaves to help the plant recover growth as soon as possible.
The above information is a complete introduction to the reasons for the yellowing and drying of leaves, and what causes the yellowing and drying of plant leaves, for everyone to learn and understand!
