About maintaining optimum moisture for indoor plants care must be taken as well as ensuring the correct temperature and light conditions. It is important to bear in mind that we are talking about air humidity for flowers and soil moisture, because most homegrown crops need regular (without fanaticism) watering and systematic leaf spraying. The only exception is the group of cactus and other succulent plants that can permanently store moisture.
For the normal development of plants you need not just air, but containing a certain amount of moisture. In nature, dew and rain give moisture to the air. Indoors, this natural air humidification does not occur. So how to be in this case?
On this page you will learn which flowers like dry air, and which plants are adapted to high humidity, as well as how to increase the humidity in the room to the optimum.
Do home plants need air?
Plants breathe, like people. But for breathing, they need first of all carbon dioxide, and then oxygen.
When you are in a stuffy, unaired room for a long time, you have headaches. Plants also feel bad in such an atmosphere: they can not breathe properly, weaken and nyko. Do you still doubt whether plants need air? Then just watch your “green pets” in adverse conditions, and you will see everything with your own eyes. In order not to ruin the flowers, the rooms where plants "live" must be aired at least from time to time.
Air more often, but not too long each time. In winter, you can open windows only on those days when there is no frost. The air in the life of plants is very important, so the smaller the room, the more often it needs to be ventilated.
When airing, make sure that no drafts occur: almost all plants cannot stand them, the majority of foliage begins to fall off. If drafts cannot be avoided, move the flowers away from the danger zone. Draft sometimes occurs due to loose old frames.
If there is something wrong with your pets, but you do not know what the matter is, conduct a draft test. Light a match and bring it to the cracks in the window frame: if the flame fluctuates or goes out completely, you need to urgently repair the cracks.
Remembering the high value of air for plants, do not forget that absolutely all flowers do not like, and sometimes do not tolerate some substances contained in the atmosphere.
A pair of paints, smells of turpentine and preservatives for impregnating wood are harmful to plants. If you are planning to repair the apartment, find a temporary shelter for 2-3 weeks for your plants, and until all smells disappear, do not return them home.
Tobacco smoke can also cause significant damage to plants. A few cigarettes a day, of course, will not hurt them very much, but constant smoking in the room leads to browning of the leaves.
Gas in the air, many indoor plants can not stand. When the gas heating system is closed, usually nothing bad happens. But if you constantly cook something on the gas stove, the plants may wither.
If you are not sure whether there is gas in the air of your apartment, check this with a bunch of carnations with unblown buds: they quickly react to the presence of gas in the air, the flowers do not open, but, on the contrary, tightly contract.
Air is important not only for the leaves of plants: the roots also breathe. Therefore you must ensure that there is enough air in the soil. For this you need:
- Often loosen the surface of the soil so that fresh air penetrates inside;
- Watering is not too abundant, so that the air voids in the soil are not filled with water.
Indoor plants that carry dry air and flowers that love moderate humidity
Indoor plants, quietly carrying dry air, include:
Euphorbia mile (Euphorbia milii)
Very strong, strong plant, tolerant both to a cool, and to a warm place. Tolerates drought. Prickly stems, milky sap of leaves and stems is poisonous, therefore transplanting Wear gloves.
Platicerium, or flat roads (Platycerium)
This is another plant adapted for growing in dry air. It is very large, bizarre. Pubescent leaves can not be cleaned and sprayed. Never pick brown, mantle leaves. Immerse in water often.
Adenium, or desert rose (Adenium obesum)
Strong plant with strikingly beautiful flowers. Unfortunately, this room color, loving dry air, is rarely sold. 2 blooms once a year.
With relatively moderate humidity 40%, desert plants and large, massive species normally feel. But most of our indoor plants require a minimum moisture content of 50-60% and even higher. This means that you have to humidify the air in the apartment. It is necessary to proceed from the fact that plants with coarse, leathery and as if wax-covered leaves tolerate dryness of the air better than those with large and soft leaves.
And remember: contain in the same room flowers, who love dry air, and plants that prefer high humidity, will not work.
Content of indoor flowers in the open air
Some plants - palm trees, agaves, ivy grow well in the event that spends the summer outdoors. They love the warm summer rain, washing their leaves, always fresh air and sun. Under these conditions, they are gaining strength and are fully prepared for the coming winter.
Most plants do not tolerate frost, therefore, it is possible to expose indoor plants to the garden only when the threat of frost has passed, i.e. somewhere in the middle of May, after the May return of the cold. The transition from one medium to another should not be abrupt. The lighting outside is much more intense than on the sunny window sill in the room. Plants are not used to it. Therefore, it is best to expose the plants to the outside on the air, on a slightly overcast day. But even in such a case, the first 2-3 of the day should be kept in a shade.
Back in the house bring "vacationers" to the first night frosts, but not immediately into the heated room, but first in a cooler place - in the bedroom or on the stairwell.
It is better to transfer the plants back to the apartment too soon, than too late.
It is very important to find a suitable place for each plant carrying or not carrying dry air.
In the sun you need to place:
Coleus (Coleus blumei, hybrids)
Date palm (Phoenix dactylifera)
Orange (Citrus aurantium)
Chinese rose (Rosa chinensis)
In partly shade place put:
Ivy (Hedera helix)
Hydrangeas (Hydrangea macrophylla)
Araucaria (Agais heterophylla)
All indoor cultures exposed outside for the summer must be protected from the winds. Do not expose plants from the room with soft, sensitive leaves that are easily damaged by heavy rain.
This includes leafy:
Uzambarsky violets (Saintpaub ionantha, hybrids)
Maidenhair lady's hair (Adiantum)
These are all such plants whose leaves can not be sprayed.
Of course, staying outdoors in the summer will be a real rest for plants only with regular watering and top dressing. Gardeners spend less time on it, because they bury clay pots with plants to the edges in flower beds or beds. Under the bottom of the pots leave a small empty space so that the earthworms can not penetrate the inside of the pot through the drainage hole. If you moisten the ground well beforehand, most of the work on irrigation can be laid on the rains. So at the same time solved the problem with the release.
Plants adapted to high humidity
Household plants who love moisture are much more than those who prefer dry air:
Cirrus aralia, or poliscias (Polyscias)
It should not be placed in a too hot room in winter, otherwise the leaves will dry out even at high humidity. This moisture-loving flower is easily affected by pests. Water only with soft water.
Aralia palmate, or shefflera (Schefflera elegantissima)
Young plants are especially beautiful. The plant is not very cheap to purchase. Does not tolerate temperature fluctuations and requires regular watering.
Allamanda (Altamanda cathartica)
A very beautiful, but capricious climbing plant that clings to the supports, which requires temperatures below 18 ° C in winter. Does not tolerate hard water. In February-March, a radical pruning.
Akalifa (Acalypha hispida)
Inflorescences spiciform, consisting of red flowers, resemble "cat's tail." Spray daily during flowering; in dry air is subject to pest invasions. In January and February, the old copies are cut off.
It needs warmth and high humidity (other species should be in a cool place in winter). The tips of the leaves quickly turn brown. Good drainage is very important. Do not be too carried away with feeding. Coconut palm tree (Cocos nucifera) Large plants (with one frond) or sprouted nuts are on sale. Grow very quickly. The tips of the leaves sometimes turn brown. Does not tolerate burning sunlight. TO pests and diseases is stable.
Attractive single plants. Leaves with a beautiful pattern. Water only with soft water. The soil should be loose, permeable, warm; air temperature is high.
Croton (Codiaeum variegatum)
Many varieties with different leaf color. Does not tolerate direct sunlight, need a diffused light and high air temperature. The soil should be warm. Water only with soft water.
Effect of humidity on home plants
Air humidity is directly related to its temperature. The colder the air, the higher its humidity. On hot summer days the air is dry, just like in the winter in a room with heating. In such situations, the plants try to help themselves: they evaporate water through the stomata of leaves and thus moisturize and cool the air next to them. The higher the temperature and the drier the air, the more water the plant must evaporate. Sometimes the amount of evaporated water is so large that it does not remain in the soil and the roots have nothing to feed up to the leaves. The plant dries out gradually.
The first signs of dry air are the brown tips of the leaves of plants such as palm trees or papyrus. In addition, there are pests such as spider mites, which love dry air.
Heating batteries are often located under the windows so that the cold air from the window glass immediately heats up and does not go further into the room.
For plants such heating is unfavorable: they are on the windowsill above the radiator and overheat. Remembering the high influence of moisture on plants, you will help your flowers if:
- Make the narrow windowsills a little wider so that the heated air deviates from the plants;
- Put all the plants in plastic pots, and then there will be no additional evaporation of moisture through the walls, as is the case if the pots are clay.
But the most important rule to follow is to constantly monitor that the humidity of the air in the room with the plants is close to optimal, suitable for your pets.
The moisture content in the air is called relative humidity and is measured in percent.
If you want to know what is the relative humidity in your apartment, buy a hygrometer (a device for determining the humidity of the air). Sometimes it is sold complete with a barometer and thermometer as a home "meteorological station." But this is not at all necessary, since There are many methods based on experience. In a room with a normal temperature, the humidity of the air usually does not exceed 40%.
How to increase the humidity for indoor plants?
The easiest way to humidify the air is to reduce the temperature, but this is completely impossible in the summer, and in the winter in an apartment is not recommended. Therefore, you need to resort to other methods to increase the humidity for flowers.
Plants that require high humidity should be regularly, preferably daily, sprayed with a spray bottle (spray).
- Spray the top and bottom sides of the leaves.
- Use only soft, not containing lime (or, at least, settled) water, otherwise lime leaves will remain on the leaves. To avoid shock from the cold, heat the water to room temperature.
- Never spray plants when bright sunshine - this leads to leaf burns.
- Do not spray in the cool evenings - in such cases the leaves dry out badly and at the same time create ideal conditions for the development of fungi.
It is important to remember! Not all plants love spraying. For example, leafy begonias with pubescent leaves should never be sprayed, and azalea flowers after spraying take on an unsightly, sloppy look.
In some plants it is recommended to cover the flowers with a sheet of cardboard. You can just spray the air around the plant. For particularly sensitive crops there are ways to indirectly moisten the air.
To maintain optimum soil moisture for indoor plants, place the flowerpots in a moist environment. To do this, you will need an extra pot of much larger size than a flowerpot. You can immediately put the 3-4 pot with plants in an empty balcony drawer. Fill the gaps between the walls of the pots and the outer containers with expanded clay. Keep the clay all the time wet, and evaporating water will humidify the air.
The required soil moisture for plants can be provided in another way. Fill a deep tray with pebbles, cover with water so that the top of the pebbles protrudes outside. Place a plant pot on the pebbles.
Creating a greenhouse room, you can provide your plants with moisture in the air and in the soil for a while even a long vacation.
- Place the plant in a large clear plastic bag.
- Water the plant well.
- Stick a few high sticks into the soil so that the packet does not touch the leaves.
- Tie up the bag at the top so that the air can no longer penetrate inside. On the inside of the bag, the evaporating moisture will flow all the time and fall into the soil.
The industry also came up with something to create a better, not too dry climate for plants (and people) in apartments.
- There are small evaporators that are hung directly on radiators. They are short-lived, but it's better than nothing.
- You can buy an electric humidifier: a sprinkler, evaporator or evaporator; The latter has established itself better than others. The evaporator consumes a lot of energy. The sprayer runs almost silently. All effectively moisturize the air, but, unfortunately, are not cheap.
- Room fountains in various versions can be installed according to your taste and wallet. In any case, they greatly improve the indoor climate.
If you put several plants close to each other, some of them will evaporate water and increase the humidity of the air for other colors. They can be planted together in one container or simply assembled in a close group.
In the same container should always be plants with the same requirements for the location and rules of care.
If you plant several plants in one container, choose one of two things:
- Or you put there potted plants, which makes it easier to remove them if necessary,
- Or take the plants out of the pots and plant them all together in the prepared soil, and they get more nutrients and grow luxuriantly. The disadvantage of the latter method is that the roots intertwine and grow together, and if you need to extract one species, you can harm all others.
