How do petunias survive the winter?

1. Wintering Methods

Since it is not very cold-resistant, it needs to be moved indoors into a warm environment. The indoor temperature cannot be lower than four degrees, otherwise the petunia will grow very slowly, almost to a standstill. It should also be placed on a windowsill where there is sunlight and ensure ventilation. Good ventilation can reduce the incidence of diseases and pests and contribute to the health of plants. Open windows frequently to ventilate the house. In winter, the growth of petunias becomes slow and their metabolism slows down. At this time, the demand for water and fertilizer is reduced. The amount and frequency of watering, as well as the amount and frequency of fertilization can be reduced appropriately. Water can be poured after being exposed to the sun, which can increase the temperature of the water, making it closer to the indoor temperature and more conducive to plant growth. If the soil in the pot is not too dry, do not water it to prevent excessive watering from causing root rot.

2. Precautions

1. Pay attention to the prevention and control of diseases and pests. Aphids and scale insects are prone to harm in winter. Do not spray them directly with pesticides. Instead, wipe them off with a rag, disinfect the plants, and place them in a ventilated place.

2. The indoor temperature is relatively dry in winter, so you can sprinkle water close to the indoor temperature on the leaves to keep them clean and help their photosynthesis.
