Low temperature exercise
Plants have a process of gradually adapting to low temperature. Sudden low temperature will bring freezing damage, but if the temperature drops slowly, many flowers and plants will adapt to the temperature by themselves
Therefore, flower friends should not move flowers and plants indoors as soon as the temperature is low. If the temperature drop is no more than three degrees, flower friends can try to put flowers and plants outdoors to exercise their frost resistance
If the outdoor temperature difference is too large and the flower friends are worried about freezing the flowers and plants at night, they can use the method of bagging at night and ventilation during the day to keep the flowers and plants warm at night
Note: it is difficult for flowers and plants to endure sudden cooling. If the temperature drops by more than 8 degrees, they must be insulated to maintain the temperature before cooling
Plant antifreeze
Cell division agents, abscisic acid and some plant growth regulators can improve the freezing resistance of plants by chemical and biological methods
Plant antifreeze was originally used to help farmers' crops survive the winter. It can also be used in flowers and plants
Usage: in late autumn or early winter, when the temperature is above zero, dilute the plant antifreeze in the proportion of 1:200 and spray the flowers and plants; Dilute at the ratio of 1:400 and irrigate the roots of flowers and plants. About every seven days, two or three times
Three to five days before the cold wave, the flowers and plants can be applied with antifreeze again, which is still sprayed after dilution at the ratio of 1:200 and irrigated after dilution at the ratio of 1:400

Note: plant antifreeze is sold on a treasure. Generally, you can buy it for less than 50 yuan. Flower friends should choose trusted drugs from large manufacturers and don't buy fake goods for cheap

Fertilization
Flower friends can adjust the application proportion of nitrogen, phosphorus and potassium fertilizer, reduce the content of nitrogen fertilizer and increase the content of phosphorus and potassium fertilizer, so as to improve the frost resistance of flowers and plants

Before winter flowers and plants enter the dormancy period, thin phosphorus and potassium fertilizer can be applied every half month. If the temperature is too low and the flowers and plants enter the dormancy period, do not apply fertilizer again. Forcibly waking up the flowers and plants may cause them to receive freezing damage

Dormancy period
Out of self-protection, some flowers and plants will automatically enter the dormancy period when the temperature is too low, lose all their leaves and become "bare pole commander"
Many flower friends may think that the plants are frozen to death. In fact, when the temperature rises and the water is sufficient next spring, the flowers and plants will sprout again

When the flowers and plants enter the dormancy period, flower friends should not water and fertilize them, otherwise they may forcibly awaken their dormancy, resulting in freezing injury, and the gain is not worth the loss
If the temperature at home is too low to ensure the normal overwintering of flowers and plants, flower friends can also promote the dormancy of flowers and plants
At this time, flower friends should gradually reduce the frequency of watering, no longer apply fertilizer, cut off some branches and leaves, and slow down the life activities of plants. Slowly, as the temperature decreases, the flowers and plants will go into dormancy

Strong plant
Flowers and plants are the same as people. If they are healthy and strong at ordinary times and the cold wave comes, they have little chance of catching a cold; If you are not healthy, sick and thin at ordinary times, even a small cooling may bring bad consequences
Therefore, flower friends should pay more attention to flowers and plants at ordinary times. They should water when they should be watered and fertilize when they should be fertilized. They often let the flowers and plants bask in the sun and keep them healthy. Naturally, the frost resistance of the flowers and plants will be enhanced
