After the leaves of the rose appear yellow in winter, it should be solved according to the situation. Improper water and fertilizer should be watered appropriately to avoid waterlogging, and fertilization should be stopped; If the light is insufficient, the sunlight should be increased, and when there is no light, the light can be used to fill the light; low-temperature frostbite should be heated and anti-freeze, and the temperature should be controlled between 15~26 °C to avoid low temperatures below 10 °C; The impact of pests and diseases should keep the growth environment ventilated and hygienic, and prune the diseased leaves and spray them with chemical solutions for control.
Solution to yellowing leaves in winter
1. Appropriate water and fertilizer
In winter, the growth rate of the rose is slow, and the demand for water and fertilizer is reduced, and overwatering or overfertilization at this time will cause its leaves to turn yellow. To water it in small amounts, generally see that the pot soil is dry before watering to moisten the soil, do not accumulate water, and stop fertilizing to avoid burning the roots and causing it to grow poorly.
2. Increase light
Because of insufficient light, the rose does not have enough chlorophyll to synthesize, resulting in yellowing of the leaves of the rose in winter, it is necessary to increase the light in time and place it in a sunny position to maintain it, so that the rose can better carry out photosynthetic growth. If cloudy weather occurs, lights can be used to supplement the light.
3. Heating and anti-freezing
In winter, when the temperature is relatively low, it is easy to freeze the rose and make its leaves turn yellow. It is necessary to control the temperature of the rose growth environment, preferably at about 15~26°C, so that it can grow healthily, and there should be no low temperature environment below 10°C.
4. Pest control
If the leaves turn yellow in winter due to the impact of pests and diseases, it is necessary to treat its growth environment, keep it clean and ventilated and free of germs, cut off its damaged leaves, and regularly spray relevant chemical solutions to prevent and control them to grow healthily.
