Most indoor flowers can easily tolerate a short drop in temperature to +10 º. How to act if signs of frostbite or freezing appear on indoor plants is described on the website of the Ukrainian publication Ukr.Media.
“Signs of freezing can manifest themselves in different ways. Ficus, hibiscus, Kalanchoe, monstera, violets, and begonias become covered with spots,” the publication says. “Codium and others similar to it react to excessive cold with drooping leaves.”
If there are warm rooms left in the house, then the plants should be moved there.
“Just don’t just place them close to a heat source – this will only make them worse,” the article noted.
Watering frozen plants is under no circumstances recommended.
If the temperature in the room does not rise, the affected plants should be sprinkled with warm water, dissolving any anti-stress drug or growth stimulant in it. After this, install a greenhouse made of plastic or cling film over the indoor plants.
