In the eyes of horticulture enthusiasts, Buxus sinica is loved for its evergreen and beautiful shape. Many caregivers encounter a problem during maintenance: the middle of Buxus sinica leaves turn yellow. This phenomenon not only affects the ornamental value of Buxus sinica but may also pose a threat to the health of the tree. This article will delve into the reasons for the yellowing of the middle of Buxus sinica leaves and provide corresponding control measures.
Reasons for the Yellowing of the Middle of Buxus sinica Leaves1. Soil problems
Buxus sinica is strict with soil requirements. If the soil is too heavy or poor, it can lead to insufficient nutrient absorption by the roots, which in turn causes the middle of the leaves to turn yellow. Soil waterlogging can also lead to root hypoxia, affecting the normal growth of Buxus sinica.
2. Improper watering
Watering is a crucial aspect of Buxus sinica maintenance. Excessive or insufficient watering can cause the middle of the leaves to turn yellow. Too much watering can lead to soil waterlogging and root hypoxia, while too little watering can cause the soil to dry out, preventing the roots from absorbing sufficient water and nutrients.
3. Improper fertilization
Improper fertilization is also one of the reasons for the yellowing of the middle of Buxus sinica leaves. Over-fertilization can lead to high soil salinity and root damage, while under-fertilization can cause insufficient nutrient supply and leaf yellowing.
4. Pest and disease infestation
Buxus sinica may be affected by pests and diseases during growth, such as aphids and red spiders. These pests extract nutrients from Buxus sinica, leading to the yellowing of the middle of the leaves.
5. Insufficient lighting
Buxus sinica requires ample sunlight. If it is kept in a dark environment for an extended period, the middle of the leaves may turn yellow.
Control Measures1. Improve soil
In response to soil problems, choose loose, well-draining soil and regularly loosen the soil and fertilize to ensure the normal growth of Buxus sinica roots.
2. Reasonable watering
Based on the growth habits of Buxus sinica, keep the soil moist without excessive or insufficient watering to prevent root damage or insufficient nutrient supply.
3. Scientific fertilization
Based on the growth stage of Buxus sinica and soil fertility, fertilize appropriately to avoid over-fertilization, which can lead to high soil salinity.
4. Control pests and diseases
Regularly inspect Buxus sinica and take timely measures when pests and diseases are found. Pesticides or biological control methods can be used to reduce the impact of pests and diseases on Buxus sinica.
5. Provide sufficient lighting
Place Buxus sinica in a sunny environment to ensure its normal growth.
There are many reasons for the yellowing of the middle of Buxus sinica leaves. Caregivers need to analyze and control based on the actual situation. By improving the soil, reasonable watering, scientific fertilization, controlling pests and diseases, and providing sufficient lighting, the yellowing problem of the middle of Buxus sinica leaves can be effectively solved, restoring vitality to the plant.
