How cold-resistant are begonia flowers?

Begonia flowers are cold-resistant at MINUS 20 degrees, and the plants are very cold-resistant. In the south of China, they can usually be put outdoors for winter. In winter, after plants enter dormancy, it is necessary to control the amount of watering and stop fertilization. When the weather is clear, plants can be placed in a position with sufficient light to enable them to carry out photosynthesis and accumulate nutrients.

Begonia flowers are cold-resistant to MINUS 20 degrees

Begonia is an arbor plant of Malus in Rosaceae. Its plants are warm-loving, cold-resistant and have strong adaptability to climate. Generally, it can withstand the low temperature of MINUS 20 degrees. These plants are very hardy. In winter, if you are in the south, you can put it outdoors. If it is in the north, when the outdoor temperature reaches MINUS 30 degrees, the plants should be moved indoors for maintenance.

Begonia flowers like light, and the light is weak in winter, so they can be placed in a position with sufficient light. In sunny weather, sufficient light can make plants carry out photosynthesis, accumulate nutrients and promote plant growth. After being exposed to light for a long time, sprinkle some water on the leaves properly to avoid water shortage.

The growth temperature of begonia flowers is above 15℃. Water plants properly in spring, generally 1 ~ 2 days 1 time to keep the soil moist. The high temperature in summer limits the growth of plants and slows down their growth. Generally, it is poured every 3 to 5 days 1 time. The evaporation in summer is large, so it is necessary to increase the air humidity and properly sprinkle water on the blades.

During the growth period of begonia, it takes about 10 days, and applying 1 times of dilute fertilizer solution, mainly nitrogen fertilizer, can make the leaves brighter and greener. Apply 1 times phosphate fertilizer about 30 days before flowering to ensure the quality and quantity of flowers, and the concentration should not be too high. In winter, plants will enter a dormant state and need to control water and stop fertilization.
