How to increase air humidity by planting flowers on the balcony of a building?

The most direct way to increase air humidity is to spray water on leaves or in the environment, which also reduces the balcony temperature and allows potted flowers to thrive. Spraying water on the leaves can also wash the leaves, which is beneficial to photosynthesis and promotes the growth and development of potted flowers. Plants suitable for foliar spraying are: pine, cypress, rubber tree, palm, brown bamboo, azalea, camellia, asparagus, lily, orchid, evergreen, Guangdong evergreen, calla lily, tortoise plastron, ferns, various flowers and trees in tropical, subtropical and warm temperate zones, and wet flowers growing in lower forests or canyons. But pomegranate, crape myrtle, elm, maple, peach, plum and other deciduous flowers and trees, if sprayed as usual, will make the plants grow white, damage the appearance and greatly reduce the flowering period. Succulent flowers such as cactus can only be sprayed on leaves at hot noon. Foliar spraying should be carried out by spraying, which can be wetted many times. Every time it is sprayed too wet, it will increase the water content of the basin soil, causing the waterlogging to be difficult to dry and the root system to rot.

The watering of balcony environment can be carried out many times with the increase of temperature, but it can only be carried out in the morning or afternoon after the balcony ground becomes cold. If you sprinkle water at noon or before the balcony floor is cold, the hot air will transpiration, which will affect the growth of flower pots, and the potted plants shaded by the balcony floor will be suffocated by the hot air immediately. It is best to spread a layer of 1.5 ~ 2 cm thick straw mat on the balcony floor and flower stand. Because of the large amount of water absorption, with the help of temperature, a large amount of water vapor can be generated. In addition, there is a shade shed on the flower stand, and the water vapor is slowly emitted, which can keep the microclimate on the balcony and flower stand at a certain humidity. This is simpler and safer than sprinkling water on the floor and the surrounding environment.

Flowers that spend the winter indoors should also have a certain air humidity, and most of the flowers raised at home are inhabited. For potted flowers that like humidity, you can cover them with plastic film or put a pot of warm water 20℃ higher than room temperature in the cover at the same time to increase the air humidity in the small environment. In a family with heating equipment, you can also spread a wet cloth on the radiator, so that steam can be generated when heating, and a local humid environment can also be created.
