Soil problemsSoil is the foundation for the growth of houseplants, and any issues with the soil can easily lead to yellowing leaves. Here are some common soil problems and their solutions:
1. Soil compaction: Soil compaction can make it difficult for roots to breathe and absorb nutrients. Solution: Loosen the soil and add organic fertilizer.
2. Excessive soil acidity or alkalinity: Soil that is too acidic or too alkaline can affect plant growth. Solution: Use neutral soil or adjust the soil pH.
3. Insufficient soil nutrients: Long-term lack of fertilization or improper fertilization can lead to nutrient deficiencies. Solution: Fertilize regularly and choose a suitable fertilizer for houseplants.
Improper wateringWatering is an important aspect of houseplant care, and improper watering can also cause yellowing leaves. Here are some common watering problems and their solutions:
1. Overwatering: Too much water can lead to root hypoxia and affect plant growth. Solution: Control watering frequency and avoid waterlogging.
2. Insufficient watering: Prolonged lack of water can cause plant leaves to wilt and even die. Solution: Keep the soil moist but avoid waterlogging.
Insufficient lightLight is essential for plants to perform photosynthesis, and insufficient light can lead to yellowing leaves. Here are some common lighting problems and their solutions:
1. Insufficient light: Move the houseplant to a place with sufficient light, such as a windowsill or balcony.
2. Excessive light: Avoid placing the houseplant in direct sunlight to prevent sunburn on the leaves. Solution: Provide appropriate shading and adjust the lighting angle.

2. Pest infestation: When pests are found, promptly clear them and use insecticides for prevention and control.
Improper fertilizationImproper fertilization can also cause yellowing leaves in houseplants. Here are some common fertilization problems and their solutions:
1. Over-fertilization: Excessive fertilization can lead to plant poisoning and symptoms such as yellowing leaves. Solution: Fertilize moderately and avoid over-fertilization.
2. Insufficient fertilization: Long-term lack of fertilization or improper fertilization can lead to nutrient deficiencies. Solution: Fertilize regularly and choose a suitable fertilizer for houseplants.
