Many bonsai enthusiasts have found that red maple leaves are often difficult to show bright red color during the maintenance process. Why are the bonsai red maple leaves not red? This article will reveal the reasons for this and provide corresponding maintenance suggestions. Environmental factors 1. Insufficient light: Red maple likes light. If it is in a dark environment for a long time, it will be difficult for the leaves to accumulate enough nutrients, which will cause the leaf color to fade and the red color to appear.
2. Uncomfortable temperature: The suitable temperature for red maple growth is 15-25℃. If the temperature is too high or too low, the leaves will lose their original red color. Soil factor 1. Poor soil drainage: Red maple is not resistant to waterlogging. If the soil drainage is poor, the roots will easily rot, affecting the normal growth of the leaves and causing the leaves to become pale.
2. Insufficient soil nutrients: Red maple has a high demand for soil nutrients. If the soil is poor, the leaf color will be affected. Watering factors 1. Improper watering: Red maple is not resistant to waterlogging. If it is watered too much, it may easily lead to root rot and leaf color becoming pale.
2. Insufficient watering: If you water too little, the red maple leaves will turn yellow due to lack of water and lose their red color. Pest and pest factors 1. Red spider: Red spider will absorb nutrients from red maple leaves, causing the leaves to turn yellow and the red color is not obvious.
2. Powdery mildew: Powdery mildew will cause white powder to appear on the leaves of red maple, affecting the normal growth of the leaves and causing them to lose their red color. Pruning factors 1. Improper pruning: Excessive pruning will cause poor growth of red maple leaves and affect leaf color.
2. Not pruning in time: If pruning is not timely, the red maple leaves will turn yellow due to insufficient nutrient supply.
Conservation recommendations: 1, choose a suitable lighting environment to ensure that red maple fully receives light.
2. Choose soil with good drainage and keep the soil moist but not wet.
3, timely watering, avoid too much or too little watering.
4, regular inspection of pests and diseases, timely prevention and control.
