What are some ways to improve the cold tolerance of flowers?

The first trick is to reduce the light.

Light not only promotes the growth and development of plants, but also provides a warm environment for flowers and plants. In order to improve the cold resistance of flowers and plants, it is necessary to gradually reduce the light duration and light intensity. The weather is already relatively cold in late autumn, and if you do cold training by then, it will be late, so you generally choose to do cold training in the middle of autumn.

Gradually reduce the light intensity, you can move indoors for maintenance, but pay attention to open the window, and place the pot at the window. It can also be placed outdoors for maintenance, but pay attention to shading. The shading here is not to reduce the damage to the leaves from strong light, but to reduce the temperature.

The second trick is to increase the temperature difference.

The temperature difference in autumn is relatively large, sometimes the weather is clear during the day, but there is a sudden rainstorm at night, the temperature is very low in the rainy days in autumn, you can put the flowers and plants outdoors to maintain, but you should do a good job of avoiding the rain. Try not to let the rain water the flowers or damage the leaves.

We improve the cold resistance of the plant, not the resistance to blows, and too much and too rapid rain can easily damage the leaves and flowers. Curing in a low temperature environment can not only improve the cold resistance of flowers and plants, but also have a good coloring effect on some succulents. Some succulents come out of shape in autumn, and the temperature difference between day and night is one of the factors that makes the succulent leaves more vibrant.

It can be said that it kills two birds with one stone.

Improving the cold tolerance of flowers can be achieved by fertilization, such as potassium fertilizer and potassium dihydrogen phosphate can improve the cold tolerance of flowers, and can also achieve the cold tolerance of plants by controlling the potting soil moisture of flowers.

Summary. Hello, happy to answer your <>

The following methods can improve the cold resistance and heat resistance of flowers, indoor insulation Set up insulation sheds for some potted plants that are cultivated outdoors but have poor cold tolerance, after winter, you can move the potted plants indoors for maintenance, the indoor temperature is relatively warmer, and the most important thing is to avoid the invasion of cold winds. If it is an outdoor plant and cannot be moved indoors, you can set up a simple thermal insulation plastic shed, and if you are a potted plant, you can put a large plastic bag, which can also have a certain thermal insulation effect. If the temperature is very low, it also needs to be covered or tied with straw, cotton cloth, etc. to keep warm.

After keeping the potted plants in the room with sufficient light, you need to pay attention to maintaining sufficient light, and should be placed in a sunny position, such as the south balcony, and should be careful to avoid placing them in a dark corner.
