Hardy plants.
If your potted plant is deciduous then congratulations, you don't need special protection for this type of plant, as long as the temperature is not extremely cold, and letting it be exposed to low temperatures outdoors will make it stronger.
Some autumn-sown biennials need low temperatures to promote growth, so be bold and let them test the cold
Wax plum. 
Plum blossom. 
Loquat. 
Pomegranate. Chilled shed plants.
As long as the ambient temperature of these plants is kept above 0, they can survive the winter without special heat preservation measures.
The cool temperatures and short days of winter cause some plants to develop flower buds that bloom brightly towards the end of winter.
Wenzhu. 
Aloe. 
Cyclamen. 
Guarana chrysanthemum. Greenhouse plants.
When the outdoor temperature gradually begins to drop, the daily temperature is about 15, it is necessary to consider taking warm and cold-proof measures for this kind of plant, move to a warmer place indoors, and pay attention to increasing the air humidity around the pot to avoid the air being too dry and causing scorched leaves and falling flowers.
Phalaenopsis. 
Calla. Succulents.
About the temperature. Succulents need to be placed indoors near the window facing the sun, or in a foam box or small shed, wrapped in thermal insulation film, and don't forget to breathe when the weather is fine. In winter, leaf cuttings, cuttings, and repotting are not recommended.
About lighting. In winter, be sure to place succulents in a place where the sun shines for the longest time, as long as the sun is sufficient, the succulents can still shine beautifully.
About moisture. The summer-type species are dormant in the winter, while the spring-autumn and winter-type varieties grow in the spring, autumn and winter.
In winter, especially in January and February, summer varieties can be watered almost without watering, or even without watering, while other varieties can be watered in small amounts.
About frostbite. If a succulent plant is frostbitten, it should not be brought from a cold place to a warm environment all at once, but should be placed in a slightly warm place, thawed slowly, and after a little recovery, it should be transferred to a warm place (of course, some of them are so cold that they may not recover).
It is important to note here that after two days, the plants that have recovered better may appear to be healthy, but have not actually recovered well. For a long time, don't touch them at will, or you will be watered and they will rot immediately. After a week or two, some of the more frostbitten parts will die of the epidermis, and the better parts will start to grow slowly, so try to wait until spring to move them.
