Flowers and trees "afraid of the cold" how to do?

Every winter is a more distressing season for flower growers, because the temperature drops rapidly in this season, and the flowers and trees that are "afraid of the cold" will be frostbitten or frostbitten to death. What methods should flower growers take in order not to watch the flowers and trees freeze?

One: trim the note

As the weather gets colder, some flowers will enter a dormant period, such as rose, jasmine, mulberry, chrysanthemum, pomegranate and other branches that blossom at the top. Before entering the room, you should have "plastic surgery" to cut off old, weak, sick, withered branches and overgrown branches. This is conducive to air circulation, promote its germination of new branches, reduce nutritional consumption, and lay the foundation for better overwintering.

Second, expand the basin and increase the soil.

Flowers and trees entering the growing period, such as poinsettia, magnolia, cyclamen and rhododendron, have passed the dormant period and began to enter the peak growing season. Before entering the house, the pots should be enlarged, the soil should be increased, and the organic fertilizer of flowers should be added to provide sufficient nutrition for the flowering period before and after the Spring Festival.

Third: prevention and control of diseases and insect pests

Some flowers and trees, after high temperature burns in summer, encounter diseases and insect pests such as aphids, red spiders and small white moths in autumn. They should be thoroughly controlled before entering the house, and pests must not be brought indoors.

Four: improve the environment

In winter in the north, the condition of indoor flower cultivation is poor. Before entering the house, according to the habit characteristics of flowers and trees, according to their different needs for temperature, light and ventilation, according to their different needs for temperature, light and ventilation, we can try to create a "microclimate" to adapt to the growth of different flowers and trees. For example, the balcony is installed to keep the temperature above 5 ℃, so that dormant flowers and trees can survive the winter normally, or make full use of windowsill and floor-to-ceiling doors and windows to build flower racks and film sheds to create a good growth environment for flowers and trees.

In winter, flower growers should enter the open-air potted flowers in the courtyard, flower bed, windowsill, balcony and other places in time, but before entering the room, they must do a good job in the early stage in order to really prevent the freezing of flowers and trees.
