What Causes the Outside of Big Chinese Rose Buds to Turn Black
The blackening of the outside of big Chinese rose buds may be due to the unsuitable soil for the plant growth, requiring an immediate change to a suitable growing soil. It could also be caused by excessive watering or insufficient lighting during maintenance, necessitating a reduction in water (G-Y) and an increase in lighting. It may also be due to disease.
1. -- Excessive Watering --
The blackening of the outside of big Chinese rose buds during growth may be caused by excessive watering during maintenance. Excessive watering leads to root rot due to waterlogging, preventing the buds from growing normally and resulting in blackening and rot. Therefore, during the flowering period of Chinese roses, it is necessary to supply water appropriately and avoid getting water on the buds.
2. -- Insufficient Lighting --
The blackening of the outside of big Chinese rose buds may also be due to insufficient lighting during maintenance. Insufficient lighting prevents the buds from developing and growing normally, leading to blackening and rot. Therefore, it is necessary to provide ample lighting and shade appropriately when the lighting is too strong.
3. -- Unsuitable Soil --
The blackening of big Chinese rose buds may also be due to unsuitable soil for the plant growth or soil alkalization, preventing the plant from growing normally. You can add an appropriate amount of vinegar solution or water soaked with orange peels to the planting soil to make it slightly acidic, helping the plant grow healthily.
4. -- Disease Infection --
If big Chinese roses are affected by diseases during growth, it can lead to blackening of the buds. It is necessary to immediately cut off all blackened buds and burn them, then spray the plant with an appropriate amount of disinfectant to kill bacteria. To prevent further bacterial infection, it is also necessary to change the planting soil and plant the plant again after disinfecting the soil.
