Cold proof of flowers in the ground: cover with earth

Before the frost strikes, first clean up the dead branches and rotten leaves close to the ground, then cover the roots with hay, sawdust, fallen leaves, etc., and then cover them with a layer of soil for compaction. This will not only keep warm, but also change the physical structure of the soil, which can make the plants grow more vigorously in the coming year

Cold proof of open flowers: straw binding

For small shrub flowers such as roses and Bauhinia at home, you can choose to gather and bind their branches and leaves with a straw rope, and then tie them tightly with straw at the periphery. Before that, you can cut the long branches first, and finally bury them in the periphery of the straw and pat them, so that the beautiful flowers can spend the winter at ease

Cold proof of open flowers: covered with plastic film

We all know that plastic film has heat preservation effect. How can we cover plastic film in the face of delicate flowers? The best way is to cover the double-layer plastic film, and the two films should be separated by 10 cm, so as to better improve the thermal insulation effect. It is suggested to lift the upper film at noon every day to prevent the high temperature from affecting the daylighting of flowers

Cold protection of open flowers: watering method

According to the specific heat capacity of water, watering will transfer the heat of deep soil to the surface and drive the air temperature near the plants to increase, so as to achieve the effect of thermal insulation

Did you remember all that? Xiaobian would like to say that in addition to the above methods, it is also important to pay attention to the nutrition of plants on weekdays and enhance the cold resistance of plants. The top priority is to learn reasonable irrigation, scientific fertilization and make flowers grow healthier
