Why do roses lose leaves in winter?

1. Causes of leaf drop

1. Lack of light: This type of plant has a weak ability to resist the cold. If it is not placed in a sunny place in winter, the leaves of the plant will fall off easily, so it should be placed in a sunny and warm place in winter; if the leaves have fallen off, it can be moved to a bright place at this time to allow the plant to grow new leaves.

2. The temperature is too low: In winter, the temperature is relatively low and the plants' ability to resist the cold is somewhat poor, so if you do not pay attention to the maintenance of the plants, they will easily be frozen. In this way, the roots of the plant can no longer absorb nutrients for the growth of the leaves of the plant, so the leaves fall off. At this time, the plant should be placed in a plastic greenhouse with a temperature of >15℃, so that the plant will grow new leaves again.

3. Improper watering: The potting soil of the plant needs to be kept moist in winter. If the plant is given too much water in winter, it will affect the breathing of the plant roots, and in severe cases it will cause the plant to lose its life. In winter, wait until the soil in the pot is a little dry before watering the plant.

4. Excessive fertilization: This type of plant has a relatively high demand for fertilizer, but giving too much fertilizer may also cause the leaves of the plant to fall off. It is generally not necessary to apply fertilizer to the plants in winter, but it is sufficient to apply it once after entering winter. If too much fertilizer is applied, you can water the plant to dilute the fertilizer or change the soil for the plant.
