This article provides an introduction to the contents: Why do the leaves of potted plants turn yellow? This article will unveil the reasons for the yellowing of leaves and provide corresponding solutions.
Reasons for the yellowing of potted plant leaves1. Improper watering
Watering is the basic skill in caring for potted plants, but improper watering can cause the leaves to turn yellow. Too much watering can lead to root hypoxia, affecting the plant's normal growth; too little watering will cause the soil to dry out, resulting in withered and yellow leaves.
2. Insufficient lighting
Potted plants need an adequate amount of light. If they are kept in a dark environment for a long time, the leaves will turn yellow due to a lack of photosynthesis.
3. Soil problems
Soil that is too acidic or alkaline, as well as compacted soil, can affect the plant's normal growth, leading to yellowing leaves.
4. Improper application of fertilizers
Overuse of fertilizers or the use of unsuitable fertilizers can result in poor absorption by the plant and cause the leaves to turn yellow.
5. Diseases and pests
Diseases and pests are also one of the reasons for the yellowing of potted plant leaves. Common pests include aphids, red spiders, and whiteflies.
Methods to solve the yellowing of potted plant leaves1. Watering in moderation
Based on the plant's growth habits, properly control the watering frequency. Watering should keep the soil slightly moist and avoid waterlogging.
2. Increase lighting appropriately
Place the potted plant in a well-lit area but avoid direct sunlight. If lighting is insufficient, consider using a plant growth lamp.
3. Improve the soil
Regularly change the soil to keep it loose and breathable. Use a mixture of soil such as decayed leaf soil and garden soil, and add an appropriate amount of decomposed organic fertilizer.
4. Reasonable fertilization
Apply fertilizers based on the plant's growth stage and needs, avoid over-fertilization, and choose the appropriate fertilizer type.
5. Prevent diseases and pests
Regularly inspect the plant's leaves and stems. If diseases or pests are found, take measures promptly. Use insecticides or fungicides for control.
There are many reasons for the yellowing of potted plant leaves, but as long as we master the correct methods, we can effectively solve this problem. In the process of caring for potted plants, we should pay attention to the plant's growing environment and adjust care measures in a timely manner to ensure healthy growth and add a touch of green to our lives.
