1、 Increase nutrients

Spring is the time when it grows vigorously. The nutrients in the soil are limited and it is difficult to meet its needs. If it is an adult plant, it is necessary to control the amount of nitrogen fertilizer and appropriately apply more phosphorus and potassium fertilizer in order to promote the opening of flowers. If it is young plants, it is necessary to increase the amount of nitrogen fertilizer to promote the growth and development of young plants and control the amount of phosphorus and potassium fertilizer. Under normal circumstances, it is OK to apply fertilizer two to three times in the whole spring

2、 Control temperature

It is sensitive to temperature. If the temperature is lower than 10 degrees, it will stop growing; If the temperature is lower than 4 ℃, frostbite will occur; If the temperature is higher than 30 ℃, its branches and leaves will be dry and scorched Therefore, in the process of curing it, it is best to keep the temperature at about 18 degrees to 20 degrees. It is not easy to maintain in the open in early spring. Try to maintain indoors. When the temperature is high in late spring, you can spray water on liger Begonia to cool down, or move to a cool place for maintenance

3、 Increase watering

Before watering it, you need to observe the condition of the soil. If the soil is completely dry, you need to water it. The watering temperature should be similar to the temperature of the breeding environment. If the temperature difference is too large, it will be unfavorable to its growth. When the temperature is high, it needs watering every day
