The temperature in winter is relatively low. Many flowers are not suitable for outdoor maintenance, so thermal insulation measures should be taken. However, different thermal insulation methods can be used for different varieties. They should be cultivated according to their suitable temperature for overwintering

1、 Increase outdoor lighting

For flowers that are relatively cold resistant, they can survive in a low-temperature environment. When they are insulated in winter, they can not be transferred indoors. They can survive normally by placing them in a place with sufficient light and increasing the temperature. They can survive outdoors or on a balcony with sufficient light

2、 Indoor warming protection

Some varieties that are not resistant to severe cold but suitable for room temperature maintenance should be placed indoors for insulation when the temperature drops to about 10 degrees in winter

3、 Bagging light insulation

Some plants also need relatively high temperature to survive the winter, such as jasmine and Narcissus. When the temperature drops to 12 degrees in winter, we need to transfer them indoors. When the temperature is lower than 5 degrees, we need to put on plastic bags and use scissors to tie several pores for ventilation. During indoor breeding, in order to avoid lack of light, move the plants to the window or balcony with sunshine at noon in good weather, receive light for a period of time, and then transfer them back after cooling in the evening
