As living standards improve, more and more families are choosing to grow flowers indoors, allowing green plants to add vitality and vibrancy to their home environment. Many novice plant enthusiasts encounter a frustrating problem—why do the leaves of indoor plants turn yellow? This article will reveal the reasons behind yellowing leaves in indoor plants, helping you better care for your greenery.
Soil Problems
1. Soil Compaction: Long periods without repotting or improper fertilization can lead to soil compaction, affecting the plant's root respiration and causing the leaves to turn yellow.
2. Unsuitable Soil pH: Different plants have different requirements for soil pH. If the soil pH does not match the plant's needs, it will also cause the leaves to turn yellow.
3. Waterlogged Soil: Waterlogged soil can lead to oxygen deprivation in the roots, causing root rot and subsequently affecting the color of the leaves.
Improper Fertilization
1. Over-fertilization: Excessive fertilization can damage the plant's roots, affecting nutrient absorption and causing the leaves to turn yellow.
2. Under-fertilization: Long periods without fertilization or insufficient fertilizer prevent the plant from getting enough nutrients, causing the leaves to gradually turn yellow.
3. Improper Fertilization Timing: Fertilization should be done during the plant's active growth period and avoided during its dormant period.
Light Issues
1. Insufficient Light: Indoor plants kept in dark environments for long periods cannot perform sufficient photosynthesis, causing the leaves to turn yellow.
2. Excessive Light: Prolonged exposure to direct sunlight can scorch the plant's leaves, leading them to turn yellow.
Pests and Diseases
1. Pests: Pests such as aphids and spider mites suck nutrients from the plant, causing the leaves to turn yellow.
2. Diseases: Diseases such as root rot and leaf spot can damage the plant's roots, affecting nutrient absorption and causing the leaves to turn yellow.
Environmental Factors
1. Temperature: Indoor temperatures that are too high or too low can affect plant growth, leading to yellowing leaves.
2. Humidity: Unsuitable indoor humidity can cause the plant's leaves to lose water, resulting in yellowing.
Plant Variety
1. Plants that have high requirements for light, water, soil, etc., are prone to yellowing leaves if not cared for properly.
2. Plants with weaker vitality are more likely to show signs of yellowing leaves in harsh environments.
There are many reasons for yellowing leaves on indoor plants, including soil, fertilization, light, pests and diseases, environmental factors, and plant variety. Understanding these reasons helps us to better care for indoor plants, allowing them to thrive. In the process of growing flowers, we should adjust our care measures according to the specific needs of the plant and create a good growing environment for them.
