Cold exercise

Plants need a gradual process to adapt to low temperatures. Sudden low temperatures can cause frost damage, but if the temperature drops slowly, many flowers and plants will adapt to the temperature on their own.

Therefore, flower lovers should not move flowers and plants indoors as soon as the temperature drops. If the temperature drops by no more than three degrees, flower lovers can try to place the flowers and plants outdoors to exercise their ability to resist frost.

If the temperature difference outside is too large and flower lovers are worried that the flowers and plants will be frozen at night, they can use the method of bagging them at night and ventilating them during the day to keep the flowers and plants warm at night.

Note: Flowers and plants can hardly tolerate sudden drops in temperature. If the temperature drops by more than 8 degrees, the flowers and plants must be kept warm to maintain the temperature before the drop in temperature.

Plant antifreeze

Cytokines, abscisic acid and some plant growth regulators can use chemical and biological methods to improve the frost resistance of plants.

Plant antifreeze was originally created to help farmers' crops survive the winter, but it can also be used on flowers and plants.

How to use: In late autumn or early winter, when the temperature is above zero, dilute the plant antifreeze at a ratio of 1:200 and spray it on flowers and plants; dilute it at a ratio of 1:400 and irrigate the roots of flowers and plants. About once every seven days, 2-3 times will be enough.

Three to five days before the cold wave arrives, you can apply antifreeze to the flowers and plants again, still diluting it at a ratio of 1:200 before spraying, and diluting it at a ratio of 1:400 before watering the roots.

Note: Plant antifreeze is sold on Taobao and can usually be purchased for less than 50 yuan. Flower lovers should choose trustworthy agents from large manufacturers and not buy fakes just for the sake of cheapness.

Fertilization

Flower lovers can adjust the application ratio of nitrogen, phosphorus and potassium fertilizers, reduce the content of nitrogen fertilizers, and increase the content of phosphorus and potassium fertilizers to improve the frost resistance of flowers and plants.

Before flowers and plants enter dormancy in winter, you can apply a thin layer of phosphorus and potassium fertilizers once every half a month. If the temperature is too low and the flowers and plants enter dormancy, do not apply fertilizer. Forcibly waking up the flowers and plants may cause them to suffer frost damage.

Dormant period

Out of self-protection, some flowers and plants will automatically enter a dormant period when the temperature is too low, dropping all their leaves and becoming "bare commanders".

Many flower lovers may think that the plants have frozen to death. In fact, when the temperature rises and there is sufficient water in the spring of next year, the flowers and plants will sprout again.

When flowers and plants enter a dormant period, flower lovers should not water or fertilize them, otherwise they may be forced to wake up from dormancy and cause frost damage, which is not worth the loss.

If the temperature at home is too low and it is difficult to ensure that the flowers and plants can overwinter normally, flower lovers can also promote the dormancy of flowers and plants.

At this time, flower lovers should gradually reduce the frequency of watering, stop fertilizing, cut off some branches and leaves, and slow down the life activities of the plants. Slowly, as the temperature drops, the flowers and plants will enter dormancy.

Strong plants

Flowers and plants are like people. If they are healthy and strong, they are less likely to catch a cold when a cold wave comes. If they are unhealthy, sickly and weak, then even a small drop in temperature may bring bad consequences.

Therefore, flower lovers should pay more attention to flowers and plants, water them when necessary, fertilize them when necessary, let them bask in the sun frequently, and keep them healthy. Then their frost resistance will naturally be enhanced.
