It is very important to maintain the air humidity necessary for flowers in the room. Some plants, such as asparagus, will never flower in a dry room, even if watered as needed. In especially whimsical plants, too low air humidity causes the shoots and buds to fall off, slows down growth.

In nature, plants live only in those places where the climate is most convenient for them. And the climate for a plant is a three-dimensional concept, it consists of temperature, illumination, soil moisture, soil structure and air humidity. In our apartments, the air humidity is very dependent on the weather, especially when the heating is turned off. Even with closed windows in spring or summer, in rainy weather, the humidity in the rooms is rarely below 50%. But in winter the air is greatly dried by heating systems. Sometimes the air humidity is 10-15% (when the batteries are very, very hot in severe frosts), and when it freezes slightly, the boiler rooms lower the temperature of the water in the batteries, and the humidity can be 30-50%. For some plants it is comfortable, for others it is not enough moisture.

How to increase air humidity

High humidity at home can be maintained in a number of ways. The most affordable method is spraying. During the growing season, most plants are sprayed daily in the morning and evening. Do not spray the plant in the sun, as you can burn the leaves. Carefully sprayed or not sprayed at all (other methods of air humidification are used), plants with stalk-enclosing leaves - in such plants, the base of the leaf petiole wraps around the stem, like a wrapper wraps around it. Stagnant water in the axils of these leaves can cause decay, especially in cold weather. Do not spray plants with pubescent (velvety) leaves (gloxinia, violets).

I must say that spraying is effective when the room temperature is about 24-26 degrees and relative humidity is about 30-40%. But if the room is a little hotter - from 26-30 degrees and even higher, then spraying is already ineffective - the moisture instantly evaporates.

What water to spray flowers

The spray water must be soft. Hard water containing salts can leave streaks on the leaves. If, when spraying, water gets on the window glass, then from salt impurities, after a week, clean glass loses its transparency. Therefore, for the purpose of humidification, it is advisable to use boiled water or distilled water.

The spray water must be warm. Cold water on leaves can leave yellow or brown spots on especially sensitive plants. Therefore, fill a bottle or spray bottle with water that is warm to your hand. When droplets are blown out, the water cools down and reaches almost room temperature on the leaves.

When a plant necessarily requires moist air, specific recommendations are usually given - place the plant pot on a tray with water, wet pebbles or peat. But sometimes concepts such as 'frequent spraying', 'regular spraying' or 'periodic spraying' are used. What do they mean by this?

Frequent spraying and regular spraying are the same thing, spraying in the morning and in the evening.

Intermittent spraying means spraying at least once a day, or every two days, this usually applies to those plants that do not require constantly humid air and periodic spraying plays a hygienic role or refreshing the plant rather than increasing moisture.

If the plant does not need to be sprayed, then it does not need to be sprayed, but if nearby plants are sprayed, then it will not be harmed either.

If the plant does not tolerate spraying, then do not place it next to the plants that you will spray so that water does not get on it. In extreme cases, the air is sprayed around such plants, and then from a very fine spray bottle.

How to increase air humidity without spraying

If spraying does not help to increase air humidity or flowers cannot be sprayed, other methods have to be looked for.

Wide containers of water will help humidify the air - this can be any tray, baking sheet or cat's tray. You can increase the humidity of the air by covering the soil in a pot or between pots with moss and keeping it moist. True, the moss will most likely have to be changed periodically - it rots. And also to lift and check the condition of the earth under it. Here it is important to moisten only the moss, but not to create increased moisture in the soil. Otherwise, insects (mushroom gnats, puffs) may start in the soil, which are invisible in the moss, but can cause significant harm. If heavily damp moss lies directly on the surface of the soil, the roots of flowers can rot from waterlogging.

If the source of dry air is a battery, then it is advisable to hang it with a damp sheet (folded in several layers) or a large terry towel. If you wet the fabric in the morning and in the evening, you can reliably protect the leaves from the directional hot stream and increase the humidity.

And of course, for the sake of this, humidifiers were invented - devices that can measure humidity and increase it. When choosing a humidifier, pay attention to the power - more powerful humidifiers work faster and more efficiently in large rooms. It is advisable to pour only boiled or distilled water into the humidifier, even if the water is not very hard in your area, there is a high probability of salt dust settling on surfaces or salt deposits inside the device.

What you need to know about air humidity:

The main rule about air humidity is that it is never possible to compensate for a lack of relative air humidity with more abundant or frequent watering. The main mistake newcomers to floriculture make is trying to increase watering when the plant is suffering from dry air.

Signs of insufficient air humidity

The ends or edges of the leaves dry out, flowers do not form, ovaries and buds fall off, when flowers bloom, they do not last long, quickly wither, spider mites often attack plants. If at the same time the soil is moistened regularly, strong overdrying of the soil is not allowed, then the point is only in the dryness of the air.

Signs of excessive air humidity

It should be remembered that excessively humid air can be as harmful to plants as dry. If the humidity is too high, microflora harmful to flowers develops intensively - pathogens of various diseases (gray rot, spots), rot spots appear on leaves, flowers or stems. By itself, high humidity does not harm the plant, if not for all the moisture-loving microbes. But the absence of air movement contributes to their reproduction. That is why in orchidariums, where there is very high humidity, several fans are placed at once.

Some plants that do not require high humidity or tolerate dry air (30-40%):

Aloe and most leafy succulents, acacia, albicia, aspidistra, asparagus, adenium, bokarnea, gasteria, hydrangea, hibiscus, ginura, wild rose, Kalanchoe, callistemon, coleus, desert cacti, clivia, euphorbia, stonecrop, oleander, some types of peperomia, radermacher, strelitzia, sansevieria, stapelia, stephanotis, sparmania, tradescantia, tolmia, ficus, haworthia, hemantus, chlorophytum, cypress and some others.

Air humidity for cacti

You know that cacti love to be sprayed, despite the fact that they are written about. The only thing that must be considered in this case is to spray from the smallest spray nozzle so that the water droplets are like specks of dust. Spraying is done early in the morning and in the evening, at a time when dew falls on the street. Spraying is carried out only in summer and only in a warm room. At the same time, drafts are avoided. You will say what it is for, but, firstly, this is a hygienic procedure, and secondly, dew loss is characteristic of almost all latitudes where cacti grow in nature, only the dew there is not the same as in our meadows - legs are knee-deep, but very light.

Air humidity for Saintpaulias

Violets (Saintpaulias) do not like getting water on the leaves, but in summer on the hottest days they suffer from dry air. Therefore, on such days, the pots of violets are removed from the windowsill and placed on the floor, because below, near the floor, the coolest and less dry air (beware of drafts), in addition, the air around the violets is sprayed from the smallest spray several times a day, this method greatly facilitates the plants to survive the heat.

A way to increase air humidity

In the summer, in the very heat, I sprayed the curtains on the window with a powerful stream from a spray bottle at night, so that they were very damp, the humidity increased and not only the flowers, but also people began to breathe easier, the curtains dried up by morning and did not lose anything from this. I did the same on very hot nights as a deputy, when the boiler house spared no coal and the batteries were fiery. In addition, during the heating season, I got into the habit of putting a damp terry towel, folded several times, on the radiator; I had to wet it three times - in the morning, after work and at night. In addition, I sprayed all the plants in the morning and evening. As a result, my plants not only do well, but also grow beautifully, among them maidenhair and asparagus, which blooms every year.
