Houseplants: lighting, watering, spraying, temperature - 4 main conditions of

Adding a new houseplant to the collection, we obtain also information on it - the necessary level of lighting and watering, feature of leaving... But what “shade-enduring“ means, for example? And how it is correct to carry out “plentiful watering“? Together with the author of the book about window plants we understand terms and we study the dangers which are concealed on a usual window sill.


It is possible to divide with a certain degree of convention all plants into the following categories:

Solar location - well lit place with a quantity of direct sunshine. As a rule, it is window sills southern or Hugo - the east / western windows.

Bright scattered lighting - well lit place, but already without direct sunshine. It can be east or western window sills, regiments or supports on insignificant removal from windows (already at distance about 50 cm from a window intensity of lighting decreases almost twice). Even usual easy curtains give effective dispersion.

the Penumbra is already location on some (to 3 m) removal from a window. Practically as same it is possible to consider illumination level near windows with northern orientation.

At the solution of a question of intensity of lighting is taken into account and such features as objects behind a window (or their absence), the floor height, purity of windowpanes and even color scale of finishing of the room and furniture (at light paints intensity of lighting is higher).

Influence of illumination on blossoming
the ratio of duration light and a night-time is of great importance For a number of plants.
For plants of short day (for example, a shlyumberger) a signal to blossoming is reduction of light day till 8 o`clock, otherwise they will only begin to expand, but will not blossom.
Some short-day plants for laying of flower kidneys even should be closed dark caps to sustain a proper correlation of length of day and night.
At long-day flowers (for example, at a saintpaulia), on the contrary, blossoming comes in the spring when day is extended, and nights become shorter. Using artificial additional lighting, it is possible to force such plants to blossom all the year round.
Having watered


Because in room floriculture “natives“ from various climatic zones are used, and the amount of moisture is required to them a miscellaneous. So, for example, the cactuses and other succulents which are “not spoiled“ in native deserts by regular watering learned to survive, accumulate moisture in fleshy stalks or leaves and it is rational to spend it. And at the cyperus growing in boggy places at the slightest drying of the soil leaves begin to dry quickly and at watering renewal are not restored any more.

Plentiful watering - a plant is watered right after drying of an earth lump, and the surplus of water which filtered into the pallet is merged approximately in an hour as some of its quantity still can be absorbed to the soil. It is possible having watered with an immersion method (only for clay pots or wattled baskets) when the pot with a plant is immersed in water to the level of the soil and wait until vials of air stop leaving.

Moderate watering - after drying of an earth lump becomes a pause in of 1 - 3 day.

Rare watering - the break between waterings can be from a week to several months.

of Accurate algorithm of watering of houseplants is not present

and cannot be as both the frequency, and volume depend on many factors at once: the plant size in what container it grows, the surface area of the soil to which there is an evaporation of moisture, temperature and humidity indoors etc. It is necessary to resolve this issue individually.

the easiest way - to touch the soil. At plants which are recommended to be watered plentifully do not allow drying of a surface of an earth lump. At those to which moderate watering is shown it is necessary to check a condition of the soil at a depth of of 2 - 3 cm - if it is dry, then it is time to water. It is desirable to carry out such inspections daily or every other day in a warm season (in the winter in cool rooms it is possible to do it once a week).

should Water with

plants accurately, an equal soft stream it is close to a soil surface. Water should not wash away roots and get on leaves (an exception representatives of family bromeliyevy which, on the contrary, should pour a little water in sheet sockets make). As the main indicator of correctly organized watering serves the beautiful magnificent plant with juicy bright leaves.

Fast drying up of leaves, their sluggish hung look, emergence of yellowness, the short period of blossoming or subsidence of buds can signal

that it is not enough moisture. And yes the more so emergence of a mold will indicate emergence of brown spots, rotting of stalks or foliage your excessive diligence. Also you should not forget about periodic loosening of the soil - roots need not only water, but also air. Neither that, nor another gets into a dense earth lump with a crust on a surface.

For watering it is desirable for p to use warm (room temperature or is a little warmer) defended (one - two days) tap water. It is possible to apply rain or thawed snow, but only in case of a favorable ecological situation in the region. And water from springs or keys can be even more rigid or saturated with iron, than water that will also not do good to plants.


Spraying of plants


relative humidity of air near is necessary for

For normal growth to the majority of plants of of 70 - 80%. In premises this indicator is practically always lower than (50 - 55%). (about 30%) air is Especially dry in the winter when from - for constantly closed windows there is no intake of more damp air from the street, and in rooms humidity strongly decreases from - for heating devices. In dry air evaporation and from a soil surface, and from a surface of leaves strongly increases. Some species of houseplants have devices for decrease in evaporation (omission on leaves, a wax raid, and at cactuses - transformation of sheet plates in prickles). These plants do not need humidity increase.

But for the majority of houseplants humidity of 30 - 40% is insufficient

for normal development. Decorative effect of leaves suffers first of all, and at the blossoming cultures flowers very quickly wither. The easiest way of increase of humidity - spraying from a usual spray, it is only necessary to use the smallest as water drops on leaves can focus sunshine and provoke burns.

However not all plants can be sprayed. Cultures with the trimmed leaves, for example, of a sinningiya (they too sometimes need to be sprayed), or with a velvety surface of sheet plates (arrowroot) badly transfer drop moisture, on their leaves ugly dark stains are formed. In similar cases it is possible to use also other ways of increase of humidity of air: pallets with wet gravel, double pots which space between walls is filled with peat or a moss - a sphagnum, spraying only air or curtains around a plant.

can gain Good effect, using household humidifiers, they are capable to regulate humidity in all room, and not just around a separate plant that will do good to all residents. During creation of pottery groups it is necessary to remember that humidity in the center of composition is higher, than at the edges therefore more hygrophilous plants should be put in the middle.

But if you regularly spray plants and emergence of a mold or spots of gray decay on leaves or flowers began to notice

, think not only of change of the mode of watering. Perhaps, plants stand too closely, and damp air in the depth of composition stands, or you overdid with spraying as drop moisture, accumulating on foliage, flows down, as a rule, in a pot, partially replacing watering. At care of large many-tier groups it makes sense to add periodically to water fungicide preparations (for example, “Fitosporin - M“, “Trikhodermin“, etc.) .



In room floriculture generally use plants of tropical and subtropical belts. And if tropical plants are good almost all the year round and demand almost identical conditions of keeping and in the winter and in the summer (the dormant period at them is not expressed), then natives of subtropics got used on two - three months in a year when on their homeland there come adverse conditions for development, to fall as if into hibernation. At them intensity of all vital processes temporarily decreases, they slowly grow, some even dump leaves. But during this period there is laying of flower kidneys, the plant gains strength before the new period of active life. Therefore for plants which are recommended to be contained in the winter in more cool conditions it is necessary to observe such mode strictly. Respectively, it is necessary to reduce, and even to reduce to a minimum their watering during this period.

Also the accurate interrelation between length of light day, intensity of lighting and temperature condition exists. The light day is longer and lighting is brighter, the admissible temperature and vice versa, reduction of lighting has to correspond to decrease in temperature indoors is higher. Surely there has to be also a difference between daytime and night time temperatures (2 - 6 ° With , and for some types and 5 - 6 ° Ñ).

Special danger is constituted by streams of cold air in the winter when airing and strong overcooling of roots if the container costs on a marble floor or a cold window sill. During airing of a plant it is better to transfer to other room and if it is difficult then to cover with the newspaper. If window leaves open often, then it is necessary to think of filters (better from transparent materials, for example, of plexiglas) which would direct air streams by plants. That the soil did not overcool from a floor or a window sill, put a pot on some heat-insulating material (the tree, plywood, isobosoms will approach).

the Favourite place for placement of houseplants is the window sill. But very few people reflected that this and one of the most “difficult“ places for a plant. On the small square, sometimes at the same time there can be different climatic zones: at glass burns the hot sun, and at night everything stiffens as in the Arctic, in a window leaf blow into ice winds, and from batteries heat rises dry, as in the desert.

the Major task - to try to smooth all these extremes, and some of them was able to use for the benefit of plants, for example, lower temperatures near glasses will be pertinent in a dormant period to natives of subtropics.
