These flower-growing rumors may have deceived you for years! Don't be fooled again

Rumor 1: Keeping volatile potted plants indoors is harmful to the human body

The truth: In fact, the concentration of volatile substances in flowers is very low in the air. Before reaching a concentration that is harmful to human health, they can produce strong odor stimulation. At this time, you only need to move it away or ventilate it in time. Therefore, it is completely possible to grow it indoors.

Rumor 2: Green plants at home can help you deal with smog

The truth: Potted plants cannot actively absorb dust particles in the air. Apart from having a certain adsorption effect on dust, they do not have any special functions in dealing with haze.

Rumor 3: Green plants such as cacti can protect against radiation

The truth: Current research shows that the electromagnetic field strength around computers and other household appliances is far less than the limit of safety guidelines, so there is no need to worry or protect against computer radiation. In addition, there is no scientific basis to support the claim that potted cacti can protect against radiation better than other things.

Rumor 4: Placing succulents at home may harm your heart

The truth: The toxic substances contained in succulents of the genus Euphorbia and the Euphorbiaceae family can indeed cause symptoms of heart poisoning, but if the juice is not ingested or in contact with the plants and they are simply displayed for viewing, it will not cause poisoning or heart problems.

Rumor 5: Green plants and bamboo charcoal can effectively absorb formaldehyde

The truth: Activated carbon materials such as bamboo charcoal can only adsorb formaldehyde but cannot truly absorb it. Although plants such as spider plants have a certain ability to absorb formaldehyde, the actual amount absorbed is limited. It is still necessary to open windows for ventilation at ordinary times.

Rumor 6: Green plants such as Euphorbia milii contain carcinogens and should not be grown at home

The truth: Potted flowers such as Euphorbia milii do contain substances that promote cancer, but the content is not high. The body will not absorb these substances unless they are taken orally. Leading to cancer promotion.

Rumor 7: Domestic pitcher plants can catch mosquitoes

The truth: The staple food of pitcher plants is terrestrial insects such as ants, and their efficiency in capturing mosquitoes is actually low. Sometimes their insect-catching bottles will become breeding grounds for mosquitoes, so we cannot expect them to kill mosquitoes. In addition, pitcher plants are extremely sensitive to the air humidity of their growing environment and are difficult to maintain in ordinary households.

Rumor 8: Green plants compete with people for oxygen at night

The truth: Green plants consume oxygen at night but release a lot of oxygen during the day. Compared with humans, the oxygen they consume is almost negligible, so there is no problem of "competing" with humans for oxygen. On the contrary, they can make the air have more oxygen ions.
