Heat as well as light, moisture, air, nutrients is one of the main conditions of plant life. Plant growth is accelerated with increasing temperature and with decreasing temperature slows down. But it is usually in the range of 12 Â° C to 32 Â° C, at a high or low temperatures, plant growth slows or stops.
On the temperature regime, houseplants require heat or cool the room. In warm indoor temperature fluctuates between 15 Â° C - 20 Â° C, cool - in the range 8 Â° -12 Â° C. In warmer areas contain plants in tropical countries. Plants subtropical countries and hardy plants in tropical countries grow and develop well in cooler areas. There are also plants are not demanding to room temperature (aloe, aspidistra, dracaena, Cleve). They grow in warm or in cool place.
Many plants are very sensitive to sudden temperature changes. It should be remembered that in winter the temperature near the window by 1 Â° C -2 Â° C lower than in the room and on the windowsill, below the 3 Â° C -4 Â° C, can be up to 5 Â° C -8 Â° C. Best of all, if you have a room thermometer. Deleterious effect of too high temperatures exacerbated by dry air and lack of light.
If the plant does not specify the temperature, and says so: moderate, not below 12 Â° C, it does not mean that the plant should grow at 13 Â° C constantly. The fact is that specifies the lower limit, which is possible for a short time, a day - twice. But if the plant is growing at its temperature limit, then it will just vegetate (unless the plant is in a state of rest). Temperature for good growth and development should be optimal. That is, for plants requiring moderate temperature - 15-18 Â° C, cool - 12-15 Â° C, heat-loving - 18-22 Â° C.
The temperature of the earth in the pot at 1 Â° C -2 Â° C lower than the surrounding air. Therefore, for some plants (euharis, gardenia, Ficus, etc., are those who write about plants that they like to keep your feet warm) is required soil heated (using the hot water in the pan, electric lamps, aquarium heaters, and so n .). Requirements to heat the plants are different in different periods of growth and development. For example, the germination of seeds of some plants require high temperature to 30 Â° C, and emerged seedlings contain at a lower temperature. During rest the plants require a lower temperature than in the period of growth.
Plants are placed on the window sill to protect both the cold air coming from windows or cracks in the frames, and the warm air batteries. This combination of cold and warm air from different directions, to plant the most unfavorable. Really can be useful pieces of foam, or a large piece of foam along the sill, and a width to cover the battery. This prevents the hot, dry air from the battery to the plant. If this page is no, you can put each pot on a separate piece of foam high, however obkladyvayut new household or office equipment. In this case, the pot will be placed much higher and farther from the hot and cold battery sill.
In a period of rest, if it is required for the plant, the temperature must be such that there was no growth, ie, it must be close to the minimum recommended temperature. Not all plants need a mandatory rest period, so try to follow the recommendations on the contents of specific plants.
