How do outdoor plants keep warm in winter?

1, balcony lighting: most flowers can continue to grow around 10℃ in winter. If the balcony at home is free, it is a good choice to put flowers on the balcony during the day, which will not occupy indoor space, but also keep the potted plants warm.

2. Indoor thermal insulation: For flowers with strong cold tolerance, they can be moved indoors for maintenance. The indoor temperature is obviously higher than the outdoor temperature, so that potted plants will not freeze to death. It would be better if there is heating in the room.

3, plastic film: If there is no heating, room temperature can not meet the needs of plants, you can also use plastic film to build a potted greenhouse, so that potted plants will enter the greenhouse, warm as spring. Pay attention to drilling several holes in the plastic bag to prevent the plants from being suffocated.

Precautions:

In winter, plants with weak sunshine, light preference or slight shade tolerance will have yellow leaves if they are placed in dark or weak light for a long time. Such as Milan, Poinsettia, Jasmine, Fusang, Geranium, Camellia, Cyclamen, Cycas, Rhododendron, Clivia, etc., need sufficient sunshine in winter.

After winter, the temperature is low, the water evaporates slowly, and the water quantity should be reduced appropriately. For plants that grow slowly in winter and are in a semi-dormant state, the basin soil should be dry. In winter, because of the low temperature, the water used for watering flowers should be stored or dried in utensils. It is forbidden to water flowers directly with tap water to prevent the root system from being damaged by excessive temperature difference.

Because the temperature drops in winter, the metabolism of flowers is slow, or they enter a dormant state, potted flowers should be strictly controlled. Shade-tolerant flowers should avoid root rot and defoliation caused by excessive watering, and the watering time should be around noon.
