As a favorite for home decoration, penjing (bonsai) is loved for its graceful shape and unique charm. Many enthusiasts encounter the issue of yellowing leaves during the care process. This not only affects the aesthetics of penjing but also brings trouble to the caregivers. This article will unveil the reasons behind yellowing leaves in penjing flowers and provide corresponding solutions.
Soil problems1. Soil waterlogging: Soil waterlogging can cause root hypoxia, affecting the plant's normal growth and leading to yellowing leaves.
2. Soil compaction: Soil compaction hinders the penetration of water and nutrients, causing insufficient absorption by the plant and resulting in yellowing leaves.
3. Improper soil pH: Different penjing plants have different soil pH requirements. An unsuitable soil pH can lead to poor plant growth and yellowing leaves.
Watering problems1. Overwatering: Overwatering can cause soil waterlogging and root hypoxia, leading to yellowing leaves.
2. Underwatering: Insufficient watering can cause the soil to dry out, preventing the plant from absorbing enough water and nutrients, and causing the leaves to yellow.
Lighting problems1. Insufficient lighting: Penjing plants require adequate lighting. Insufficient lighting can lead to slow growth and yellowing leaves.
2. Excessive lighting: Long exposure to strong sunlight can cause leaf sunburn, leading to yellowing leaves.
Pest and disease problems1. Spider mites: Spider mites extract the sap from plant leaves, causing yellowing leaves and, in severe cases, leaf drop.
2. Rot disease: Soil waterlogging or excessive watering can lead to root rot, causing yellowing leaves.
Fertilizing problems1. Over-fertilizing: Over-fertilizing can cause high nutrient concentrations in the soil, preventing plant absorption and resulting in yellowing leaves.
2. Under-fertilizing: Insufficient fertilizing can prevent the plant from obtaining enough nutrients, causing the leaves to yellow.
Solutions:
1. Improve the soil: Replace with new soil, ensuring good soil drainage and preventing soil compaction.
2. Control watering: Adjust the watering frequency and amount based on the plant's growth habits.
3. Adjust lighting: Place the penjing in suitable lighting conditions, avoiding long exposure to strong sunlight.
4. Prevent and control pests and diseases: Regularly inspect the penjing and take timely measures to prevent and control pests and diseases.
5. Fertilize rationally: Apply fertilizers based on the plant's growth stage and needs.
