The cold tolerance is not high, so it should be kept indoors. The temperature should be higher than four degrees, otherwise growth will stagnate. It should be placed on a sunny and well-ventilated windowsill. Keep the window open for ventilation, which is conducive to plant growth. In winter, water and fertilizer requirements become lower, so the amount of watering and fertilization should be appropriately reduced. If the soil in the pot is not too dry, don't water it to avoid watering too much and causing root rot. Pay attention to pest control. Spray water close to room temperature on the leaves to keep them clean.

1. How to spend the winter

1. Overwintering methods

Due to their low cold tolerance, they need to be moved indoors into a warm environment. The indoor temperature cannot be lower than four degrees, otherwise the petunia will grow very slowly and almost stagnantly. Also place it on a windowsill with sunlight and pay attention to ventilation. If the ventilation is good, it can reduce the incidence of pests and diseases and contribute to the health of the plants. Open windows frequently to ventilate the room. In winter, the growth of petunias becomes sluggish and their metabolism slows down. At this time, the demand for water and fertilizer is reduced. You can appropriately reduce the amount and frequency of watering, as well as the amount and frequency of fertilization. Water can be poured after being exposed to the sun, which can increase the temperature of the water and make the water temperature closer to the indoor temperature, which is more conducive to plant growth. If the soil in the pot is not too dry, do not water it to prevent root rot caused by overwatering.

2. Precautions

1. Pay attention to the prevention and control of pests and diseases. In winter, aphids and scale insects can easily cause damage. You cannot spray pesticides directly. Instead, wipe them off with a rag, disinfect the plants, and place them in a ventilated place.

2. In winter, when the indoor temperature is relatively dry, you can sprinkle water close to the indoor temperature on the leaves to keep the leaves clean and contribute to the photosynthesis of the leaves.
