Before purchasing a plant, you need to know the light conditions it needs. The amount of light in rooms depends on the size of the windows and their location. It is most beneficial to have windows facing south-east and south-west. Plants on such windows will be illuminated in the morning and almost all day. South-facing windows are better lit in winter, but in spring and summer they get very hot, so in the afternoon it is better to shade the plants on them, except for the most sun-loving ones (adeniums, pachypodiums, etc.).

The windows facing west and east are almost equally illuminated, only at different times of the day and practically do not require shading. For some reason, many people have a strange attitude towards the northern windows, some even believe that it is impossible to grow plants on them at all, this is not so. There are a huge number of plants (we will give some below) that grow well on the northern windows, moreover, there are cases when cacti were grown on the northern windows (and they are, as you know, light-loving), and they not only grew beautifully, but even bloomed.

The larger the windows, the more light the plants receive, the closer the plants are to the window, the better their illumination. For any arrangement of windows, you should not shade them with thick curtains (if the description of the plant speaks of shading, then a tulle curtain is enough for this, you can have a mosquito net if the plant is on the windowsill).

Lighting at different times of the year

A very important point: at different times of the year, the intensity of sunlight in our windows is different, conditionally, the whole year can be divided into two periods, for central Russia:

  • From March to August, i.e. spring-summer - during these months there is an intensive growth of all plants, and flowering in most. During this period, the sun can be very aggressive, and all the recommendations below on the content, or rather the correspondence of various plants to the cardinal points, are given precisely for this period. When it comes to shading, this only applies to spring and summer.
  • From September to February: the period of passive sun, daylight hours are greatly reduced, the sun is low, plants naturally want to slow down growth. But the problem is that they only "want", "want", some "dream" - but usually they cannot, due to the fact that the temperature at home remains high enough due to the included heating. Therefore, the plants continue to grow (in the range from 14 ° C and above), but from a lack of light they stretch and disfigure. During this period, almost any plant can be safely placed without shading on the sunniest windowsill. They are not afraid of the sun on the south window, because it rarely shines, shortly and the rays are oblique.

North windows

There are many beautiful indoor plants that require diffused light and are therefore well suited for placement on or near a north window. The flowering plants of the northern window include saintpaulia, or the uzambara violet, exotic hybrids of Scherzer's anthurium, cyclamens, and Kalanchoe. Hybrid types of begonias are also suitable for this, for example, the Lorrain begonia. If there is enough space on the windowsill, then you can place an unpretentious but beautifully flowering passionflower on it, which, although photophilous, will bloom on the northern window (after flowering, it is cut off). Most bromeliads will grow well on the north window as well. Some palm trees can be placed near the window, for example, a beautiful hovea or Lorer's date. On the north window it is worth considering the temperature difference, i.e.Plants in warmer rooms tend to need more water than plants in cooler rooms.

Plants for the north window

Aglaonema, maidenhair, aspidistra, asparagus, aucuba, angular begonia, oriental biota, helksina, dracaena bordered, fragrant dracaena, zygocactus, saxifrage, kalanchoe, red caraguata, large-reed groundwort (not variegated), ligoderae, ligodera gray and dull-leaved peperomia, nightshade, ferns, ivy, passionflower, sansevieria, scindapsus, spathiphyllum, selaginella, tolmia, fatshidera, fatsia, ficus, climbing philodendron, fittonia, rhomboid cissus, cineraria, cyperia.

South windows

Growing plants on the south window is more troublesome than on the north one, as few plants will endure prolonged exposure to direct sunlight. Often, at the hottest time of the day, you will have to create shading, in the form of a gauze or tulle curtain. This is inconvenient because when you are at work, there is no one to do this and the plants may suffer.

Therefore, you need to carefully select plants on the sill of the south window. Only the most resistant and sun-requiring plants can be placed on the windowsill itself, for example cacti and other succulents, hibiscus, adenium, passionflower, etc. If you read in the recommendations for caring for the plant that it is light-requiring, but needs shading, then place it on a table near the south window under the protection of a tulle curtain. Such a place is ideal for such decorative leafy flowers that need bright but diffused light, for example, ficuses, arrowroot, myrtle, hamerops, cissus, coleus, hoya

Plants for the south window

Aloe, bokarnea, bouvardia, Sambac jasmine, Japanese camellia, coleus, coffee, laurel, mammillaria, prickly pear, oleander, stonecrop, Chinese liviston, plectrantus, rheo, fuchsia, haworthia, cerius, echinocactus, yucca. It should be borne in mind that each species of the same genus may have a different need for the sun, for example, some types of aloe grow well in the southern window, and some burn out, the leaves turn gray.

Eastern windows

The eastern windows have much less illumination than the southern ones, and they differ from the western ones in that in the morning the rays are not so scorching and shading is not required on the eastern windows. The plants of the east window include:

asparagus, aucuba, tree begonia, hairy begonia, metal begonia, emerald begonia, griselinia, narrow-leaved dracaena, dracaena deremena, butcher, myrtle, ivy, cissus, pittosporum, japanese fatsia, violet ficus ussumbar, epiphyllum blunt.

Western windows

Western windows, as a rule, are warmer than eastern ones, shading on them is not done only for very light-loving plants, because it is easier for the plant to get burns on the western window than on the eastern one, look and observe for yourself, if the leaves begin to fade, then you need to shade. Western window plants include:

asparagus, begonia rex, bilbergia drooping, veronica Andersa gasteria, eugenia, low jasmine, sansevieria, strobilantes, Akkerman's phyllocactus, Gunther phyllocactus, date palm, cissus, hamerops, eucalyptus, echmea.

All the examples of plants given are calculated on the fact that the plant will be placed on the windowsill, and not in the room.

And also for those who are guided not by the cardinal points, but by the illumination of the room:

Light, without direct sunlight (window sill, where direct sunlight does not fall, or a place near a very bright window):

Azalea, anthurium, asparagus, royal begonia, bromeliads, grapes, dizigoteca, dieffenbachia, zygocactus, columnea, monstera, peperomia, pilea, ivy, spathiphyllum, scindapsus, philodendron, fuchsia, chlorophytum, cyclamen, sheflera.

Direct sun occasionally (window sill or place in the immediate vicinity of the east or west window):

Balsam, beloperone, ginura, zebrina, capsicum, codiaum, kufeya, nertera, poinsettia, sansevieria, lead, Saintpaulia, nightshade, sparmannia, tradescantia, rubber ficus, chlorophytum, hoya, chrysanthemum.

Solar window (sill of the southern window or a place in its immediate vicinity):

Agapanthus, acacia, bougainvillea, bouvardia, heliotrope, hibiscus, hippeastrum, jasmine, zebrina, irezina, cacti and other succulents, callistemon, coleus, lantana, citrus fruits, nerina, oleander, oxalis, passionflower, rosacea, celargonium.

  • All flowering indoor plants prefer slightly brighter lighting than decorative leafy species, since light is essential for the formation of flower buds.
  • Plants with variegated leaves require more light than plants with green leaves.
  • Light walls in the room reflect light, i.e. make the room brighter.
  • Plants suffer if they are often rearranged from place to place, especially with different illumination.
  • In winter, the plants must be placed closer to the window, or the plant must be illuminated additionally when signs of lack of light appear.
  • Dirty glass blocks up to 40% of the light, so try to clean your windows more often. In winter, you can take advantage of the opportunity and wash the glass at any above-zero temperature.
  • A newly transplanted and just purchased plant should be shaded for the first two weeks. Also, most plants need to be shaded from the midday sun.
  • Some plants periodically need to be turned in different directions to the light source (unless there are buds on it), for uniform leaf formation.
  • There are exceptions to all these rules, so read in detail about your plant and the rules for its maintenance in the encyclopedia section.
Signs of a lack of light Signs of excess light
  • Leaves are pale and smaller than they should be
  • There is a tilt of the top of the bush (branches) towards the light source
  • The plant does not bloom or the flowers are small and dim
  • The stems of the plant are elongated with very long internodes
  • The variegated leaves turn green
  • The lower leaves turn yellow, dry up and fall off
If the plant has stood in the sun and:

  • The leaves are lethargic, drooping
  • Leaves become faded (discolored like faded tissue)
  • Some parts of the leaf are discolored or reddened
  • Brown spots on leaves
