In the northern part of our country, there will be heating in winter, at this time, if potted flowers are planted indoors, it is easy to cause the leaves to dry up or even turn yellow, so how to deal with this situation?

For some time after heating, the ornamental plants raised at home have different degrees of dry yellow leaves, some of which are dried up and some of them are withered at the edge of the leaves. What is the cause of all this?

This is mainly due to the dryness of the decline in indoor air humidity after heating. Air humidity plays an important role in the environmental factors of plant growth. Many family flowers and trees like humid air, requiring air humidity of more than 70%, and tropical plants such as "aerial root" tropical orchids need higher air humidity. In the case of heating, the humidity in the room is generally about 40%, which is far from meeting the needs of plants for the environment. Such as Phalaenopsis, Cymbidium and Belgian rhododendron cannot grow normally when the air is dry. When the air is dry, there is a large amount of water transpiration in flowers and trees, and the rate of water absorption in roots is less than that of transpiration, resulting in the imbalance of water in flowers and trees, resulting in the phenomenon of scorched leaves and fallen leaves.

The common moist flowers and trees in the family are: tortoise-backed bamboo, Jianlan, Phalaenopsis, Cymbidium, slipper orchid, Magnolia, Magnolia, Dendrobium, Cartland, Zhu Jiao, Magnolia, pineapple, iron orchid, fire crane, pocket coconut, autumn begonia, peacock bamboo taro, purple-backed bamboo taro, apple bamboo taro, ruby, emerald, spider holding egg, asparagus, leaf-changing wood, parasol, evergreen, green apple, weeping leaf banyan and so on. At this time, the correct maintenance method is: should often spray water to the leaf and the surrounding ground or use a humidifier to increase air humidity, but when spraying water should avoid basin soil too wet, in order to prevent rotting roots. Methods such as spraying and washing branches and leaves or covering the basin soil with plastic film can also be taken to increase humidity.

Flower friends can appropriately increase air humidity according to the habits of plants, so that plants can survive the winter safely.
