Temperature conditions for domestic plants

For active growth and development of indoor plants, proper temperature is no less important than proper lighting. Therefore, before acquiring a green "pet", you must find out at what temperature you need to keep this flower house. Some plants to adequately lower or rise in temperature react adequately, enduring all inconveniences. And others can lose the leaves and refuse to bloom even from the slightest draft.

Since "indoor green pets" come from different climatic zones, including tropical and subtropical, they impose different requirements on the ambient temperature.

You will learn in this material what temperature the flowers can withstand in different seasons, and what temperature conditions should be provided for plants in summer and winter.

At what temperature to keep flowers in summer and winter

Summer temperature for indoor plants - not a problem. Summer will not cause you much trouble in terms of temperature for flowers. For most homegrown crops, the warm season is a period of intense growth.

The optimum air temperature for flowers in summer is from 16 to 22 ° С (average temperature for a temperate climate zone, and maximum temperature up to 30 ° С and higher). Do not forget in the warm season to spray the plants with cool water.

In the fall, when the days gradually become shorter, and the conditions for growth are no longer ideal, some plants, both garden and indoor, have a period of rest. For this holiday plants need a cool. The air temperature should be much lower than in heated premises.

If you look in the instructions for the care of individual plants, you will find there information on the winter temperature for each species. According to these data, all plants can be roughly divided into large groups of 3:

  • Plants that need air temperature around 20 ° С even in winter:

Leaf begonia

Cirrus Aralia (Potyscias)


Aralia palmate (Schefflera etegantissima)


Coconut palm (Cocos nucifera)

Aglaonema (Agtaonema)

Calathea (Calathea)

Croton (Codiaeum)

And many others.

  • Plants that prefer moderate temperatures during the dark season (10-16 ° С). This group includes most of our famous indoor species.
  • Plants that from October to February should be kept at temperatures below 10 ° C. To them belong:

Date palm (Phoenix dactylifera)

Bokarneya (Beaucarnea recurvata)

Yucca (Yucca)

Araucaria (Araucaria)

What temperature do flowers stand for?

Unfortunately, the preferences of plants of a particular temperature cannot be determined by their appearance and leaves, as can be approximately learned with regard to the mode of lighting. Even species belonging to the same family rarely have the same requirements, everything is purely individual.

Example: Yucca (Yucca) and Cordyline (Cordyline) belong to the Agavaceae family. Yukka needs a cool place in winter, but cordidine, on the contrary, is very warm. This also applies to most types of cordilina, although there are differences among them too.

In general, only about two groups of plants can be said definitely (and with some exceptions) the following:

  • Most ferns love heat.
  • Most cacti need cool in winter.
  • Palm trees have many different requirements.

If you want your pets to tolerate the winter well, cope with the purchase of each instance, at what temperature the plants feel comfortable.

Insert small plastic plates into pots with separate species, as gardeners always do. On them, note what the optimum temperature is required by this plant, what kind of light it needs and humidity air.

Plants requiring warm air and soil temperatures

Listed below are plants that require warm temperatures when kept at home.

Philodendron (Philodendron)

This plant has been known for over 150 years. It is characterized by long aerial roots. He needs a warm atmosphere all year round. Soil temperature should not be lower than air temperature. Does not tolerate glossy leaves.

Crossander (Crossandra infundibuliformis)

Does not tolerate sunlight, loves high humidity. When spraying try not to wet the flowers. Sensitive to cold and damp at the base.

Ficus (Rubber plant)

There are different types on sale, and they all need a warm location with diffused light. Sensitive to waterlogging. Spray more often in a room with central heating, where the air is dry.

Maidenhair lady's hair (Adiantum capillus-veneris)

Dark brown, wire-like stems are typical of this plant. All year round this plant needs air and soil temperature not lower than 20 ° С, as well as increased air humidity. In a dry atmosphere, it withers.

Shlemnik, or scutellaria (Scutellaria costaricana)

Interesting spike inflorescences bright red flowers. The optimum air temperature for these flowers in winter is not lower than 15 ° С. Do not cut the tops of the stems, because flowers are formed only at the ends of the shoots.

Croton, or Codicium (Codiaeum)

Amazing plant, captivating leaf color from green, yellow and orange to red, almost black. Croton's milky juice irritates the skin and mucosa. The plant does not tolerate drafts. The air temperature in winter should be above 16 ° C.

Dipteracantus, or ruellia (Dipteracanthus)

Creeping plant with soft leaves, which stand out white veins. Does not take out dry air in homes with central heating. Water should only be soft water at room temperature. Can be grown as an ampelous plant.

Peperomia (Peperomia)

In the regions of natural growth is an epiphyte. All year round requires a warm location. In winter, on the cold soil, the bases of the stems may rot.

Effect of temperature on plant life and adaptability

Many types of house flowers are able to adapt to the temperature in the room, i.e. among the indoor crops there are a number of those that can tolerate both elevated and lower temperatures. In order for plants to adapt to temperature successfully, follow these rules:

  • The higher the temperature, the brighter the place where the plant stands.
  • The cooler the room where the flower hibernates, the less it needs to be watered.

Home cultures are always better tolerated by heat than cold. Of course, the elevated temperature for plant life is uncomfortable, they develop poorly, look sick, and therefore require additional care and attention.

The effect of excessively low temperature on plants has more serious consequences. If it is very cold, the flower freezes at worst and cannot be saved by any measures.

If a plant winters from year to year in a very warm room, in a few years it will wither; if it is a decorative flowering species, it blooms very poorly.

Where to keep plants at low temperatures?

If your apartment has adjustable heating, i.e. in the afternoon, temperatures around 20 ° С and at night they decrease by 5-7 ° С, this has a positive effect on the plants, giving them a break for rest. However, this does not apply to those species that should be in a cool place in winter. From the beginning of October, when the heating is turned on, they need to be taken out of the warm rooms “to winter apartments”.

  • Plants that need 12-13 ° C in winter can be placed in an unheated bedroom, in a bright front room or in a stairwell. Make sure that there are no drafts!
  • Plants that overwinter at temperatures just a few degrees above zero are much more difficult to arrange. You can put them in a bright basement or in the attic, in a greenhouse with the appropriate temperature or, if there is no place else, in a bright garage. But in this case the car does not belong there, because plants do not tolerate exhaust gases. If you do not have suitable premises where you can keep plants at low temperatures, attach them to good friends or acquaintances.
  • Sometimes it is recommended to take the plants to the specialized farms for the winter, where they will be provided with proper care. Good advice, but it is a double-edged sword. On the one hand, where to find such a farm? And on the other hand, there are prices that will pay off only when it comes to large, expensive plants in tubs.

Rid yourself of the "winter" problems. Acquire types that in the winter will not make special demands on the temperature regime in your apartment.

In connection with the temperature should be said about some details, especially important for the healthy state of plants.

Temperature fluctuations, i.e. its increase or decrease, various types of tolerance is not particularly good. Therefore, greenhouse specimens purchased in the nursery and brought home, as well as plants that were outdoors all summer, must first stand in some kind of intermediate room in order to gradually get used to room temperature. Some species are particularly sensitive to temperature variations, such as bougainvillea and gardenia.

"Cold feet" can kill the plant. The temperature of the soil in the pot should be about the same as the temperature of the air. If the pot is on a cold stone floor or on a marble window sill, you need to place a wooden plank or some insulating material under it, for example, polystyrene.

Ice patterns on the windows can freeze indoor plants. Make sure that during the frosty nights your players do not touch the leaves of the window glass. If the forecast promises a severe frost, lay cardboard or several layers of newspapers between the glass and the plants.

Floor heating, giving a pleasant warmth from below, is not harmful to plants, except for those that require very low temperatures in winter.
