The temperature of 18-23 ° C, which is maintained in living quarters, is optimal for most indoor plants. For a short time, many plants can easily tolerate temperatures slightly higher or lower than usual. However, a prolonged increase or decrease in temperature should not be allowed.
Most of your plants will be comfortable if you keep the temperature around 20 ° C in winter and around 23 ° C in summer.
Tradescantia, epiphyllum, dracaena, cordilina, ficus, philodendron, cyperus, etc.
Some types of palms (date, Kentia), all cacti, orchids, bromeliads, fittonia, etc.
Even a short-term drop in temperature to 7-9 ° C can cause the death of thermophilic plants such as pineapple, some types of passionflower, wax ivy (hoya), alocasia, plumeria.
Plants that thrive in a cool room: olive, fuchsia, agave, oleander, agapanthus, roses, cyclamens, daffodils, crocuses, etc.
In a bright ventilated place at a temperature not exceeding 10 ° C, they feel great: yucca, grevillea, fatsia, camellia.
Proper ventilation of the premises is a very important condition for caring for indoor plants. Fresh air is essential for plant life and development. However, try to avoid drafts. In some woody plants, for example, ficuses, hibiscus, a decrease in temperature as a result of a cold draft can cause leaves to fall off, and the plant will lose its decorative qualities.
In the summer, the temperature can be regulated by ventilation, in the winter - use the heating controller on the batteries.
Also in winter, you can use the heat of the batteries if you build up the windowsill. To keep the pots from overheating, you can put a piece of styrene foam on the windowsill.
It should be remembered that when the temperature drops below the optimum, plant growth slows down and stops completely at a certain period. A too strong drop in temperature can cause the death of the plant.
In cooler rooms, it is necessary to place the inhabitants of the subtropical zone with a cool winter period: ivy, butcher, azalea, bulbous at rest. The optimum winter temperature for them is around 10 ° C.
Tall and heat-loving plants should not be placed near the window or balcony door.
Hot and dry air from central heating radiators is also a plant hazard. Never place the pot with the plant close to the radiator, as the roots will overheat and often dry out, and the top of the plant will be in a stream of hot air rising from the radiator. This will damage the root system and cause leaf fall.
If your room does not have metal-plastic windows, then by all means make insulation, seal all window gaps for the winter.
Small pot holders will also help prevent hypothermia. Cold air flowing down from the windowsill will bypass the pots without overcooling the root system of the plants.
