Clivia is not considered a demanding plant, however, it blooms only in a cramped pot, after a short period of dormancy.

Not all indoor plants bloom at home. Some do not bloom either in a greenhouse, or in a greenhouse, or at home, others can bloom only in greenhouse conditions that are closest to natural ones, but there is also a large group of plants that bloom in indoor conditions. Among them there are demanding and not very, completely unpretentious, which, even when they forget to care for them, not only grow, but also bloom (for example, some types of cacti, pelargonium, etc.).

Let's try to consider the most likely reasons why plants do not bloom, bearing in mind that they should bloom in indoor conditions.

Little light

First of all, this is a lack of lighting, and not necessarily direct sunlight (not all plants tolerate them), but bright diffused light. Almost all flowering plants need good lighting, few plants bloom on the northern windows, and even more so in a semi-dark room. But many plants bloom beautifully under artificial light, especially with fluorescent lamps.

Even if there is no natural light at all, but the lighting with lamps is properly organized, the plants will grow and can bloom well. Therefore, if the plant does not bloom, then first you need to think about whether it has enough light. You should also take into account the length of daylight hours, usually at least 10-12 hours.

Wrong soil

For some reason, very little attention is paid to the correct composition of the soil mixture, and rarely does anyone check the acidity (pH) of the soil before applying it. Although in fact, it is not uncommon for purchased potting soil mixtures to have a pH far from what was indicated on the package. Most plants prefer soils with a slightly acidic reaction of pH 5.5 - 6.5 (these are asparagus, amaryllis, begonias, primroses, calceolaria, pelargoniums, tradescantia, etc.). Some plants prefer acidic soils with a pH of 4.5 - 5.5 (azaleas, hydrangeas, gardenias, calla lilies, camellias, fuchsias, anthuriums, etc.), few plants like soil with a neutral pH of 6.5 - 7, 5 (roses, chrysanthemums, cineraria). Many of the plants listed above will not bloom if you plant them in soil with inappropriate acidity, or if their bloom is sluggish. Therefore,if your plants have enough light, work out the soil to see if it is good enough for these flowers.

Incorrect transplant

This is one of the main reasons for the lack of flowering in indoor plants. In this case, there can be many violations: too spacious or too tight container (for example, clivia blooms well when the pot is cramped); root damage, even minor or completely invisible, especially in plants that reproduce only by dividing the bush (for example, spathiphyllum), can lead to the fact that even a rather unpretentious plant does not bloom for a long time. Transplanting at the wrong time of the year, for example, in autumn or winter, is even fraught with the death of the plant. Planting bulbs too deep when a lot of earth is sprinkled on top.

Plant nutritional disorders


Adeniums can grow on northern windows, but they will bloom only on sunny windows, or with additional lighting.

This point includes situations when the plant is starving, it has not been transplanted or fed for several years (it may have been planted in very infertile soil), or when it was fed too much with fertilizers, especially if these dressings are incorrectly selected. For example, they contain a lot of nitrogen. In such cases, they say - the plant "fattens" - it forms large juicy green leaves, vigorously grows new shoots, all forces are directed to vegetation.

Sometimes plants need to gain strength for the next flowering, to increase the mass of the storage organ. For example, after flowering cyclamens grow tubers, storing nutrients for future flowering. Therefore, when the plants have faded, the cyclamens cannot be immediately cut off and taken to the basement. It is necessary to continue to water the plants little by little, reducing feeding, and when the leaves turn yellow and die off, cut them off and put the tubers for storage.

Violation or absence of a rest period

Not all plants, but many, in order to bloom in winter or spring, need a dormant period, which consists in keeping in fairly cool conditions and very limited (sometimes almost dry). Illumination depends on the plant - some go through a dormant period in a shaded place, others in a fairly bright place. Usually, the care recommendations tell you whether the plant needs a mandatory dormant period or not (see the Encyclopedia).

Air is too dry

It can also be the reason for the lack of flowering in indoor plants. It should be noted that if the temperature in the apartment is higher than 26 ° C, then periodic spraying only temporarily refreshes the plant, and this is not enough. Therefore, if the plant needs very humid air, such as orchids, then the pot with the plant will have to be placed on a tray with water (wet pebbles), and possibly also sprayed.

Damage by pests

Oddly enough, this is not the most common reason for the "non-flowering" of plants, but nevertheless, with a very strong defeat, for example, by thrips or whitefly, the plant not only grows and develops poorly, but also does not tie buds. If the pest did not have time to greatly spread on the plant, then it can bloom, but then it will begin to lose both buds and flowers.

There are other, less common reasons why the plant does not bloom. This may be incorrect pruning - in some plants flower buds are laid only on young shoots of the current growth, in others - on last year's old shoots. Or a violation of watering, for example, severe overdrying or watering with chlorinated or hard water, can cause the concrete to fall off. Many plants have their own characteristics, for example, orchids bloom in a dry period, when the rains stop in nature (the air humidity is still quite high), if you start to water them abundantly or spray them at the beginning of bud formation, then you can not wait for the flowers, but the plants a new growth of the vegetative mass will begin.
