Lack of light, lack of fresh air, excessive dryness, draft, sudden temperature drop, dry soil or excessive watering, lack or excess of nutrients - all this leads to oppression of plants, causes not only their painful state, but also creates favorable conditions for pests and disease.

Very often, mainly from novice florists, you can hear the question: “I don’t know what the flower is dying from, what to do? If it’s completely unclear what’s the matter, then you need to sort it out in order, based on the most likely versions.

For example, wilting of leaves when they are hanging with limp rags occurs for several reasons:

  • waterlogging of the soil,
  • overdrying the soil,
  • heatwave.

It is possible to determine whether the plant was overdried or flooded by the state of an earthen coma (see below). And the heat harms potted plants when the thermometer rises from 38 to 45 degrees. Some plants can tolerate higher temperatures (succulents), and many die.

If the leaves do not hang with rags, but simply dry and fall off, a third reason is added - pests. Pests or diseases, in general, can also be identified by making certain efforts (see pests) - by comparing them from photographs (in the section there are photos of scale insects, scale insects, thrips, ticks, etc.)

If the soil looks neither too dry nor too wet, no pests have been found, then you will have to remove the plant from the pot and examine the roots (pests can also be on the roots). If, on examination, it turns out that the healthy roots of the plant fill the entire earthen lump, then the depression is associated with a lack of nutrition, the plant should be transplanted into large pots with fresh soil. If it is found that the roots are lethargic or begin to rot, then again it is necessary to transplant the plant, removing the affected areas of the roots. When examining an earthen coma, it may turn out that it is overdried, in this case, measures must be taken to uniformly moisturize the plant.

When the earthy clod and roots are in order, then the reason should be sought in a lack of light or dry air. In the first case, the plant should be moved closer to the light, in the second case, regular spraying should be carried out, and in addition, in winter, hang the central heating batteries with wet towels. Finally, you need to pay attention to the appearance of the plant. Is the cause of the depression caused by contamination of the leaves, for example with dust, as a result of which the respiration processes are disrupted.

Some growers have a good habit of taking a shower once a week (or at least a month). It is even better to wipe the leaves with a soft sponge. This procedure has a very beneficial effect on the condition of indoor flowers.

To prevent the appearance of thrips, spider mites, all kinds of worms, aphids, as well as pathogenic fungi, it is necessary not only to wash or bathe the plants more often, but also periodically use an infusion of Persian chamomile (feverfew) or tobacco for washing.

Dried, limp leaves must be removed, as they often become a haven for all kinds of parasites. It is also necessary to keep the pots clean, remove dust and mold deposits, and check if the drain hole is clogged. The soil in pots must be loosened regularly, carefully, being careful not to damage the roots. Remove sprouted weeds.

Here are the most common problems that probably everyone who grew flowers faced:

This photo shows a plant (maidenhair) affected by too dry indoor air. In this case, the tips of the leaves first become dry, dry brown spots appear, the leaves turn yellow and die off. The lower leaves also fall and dry up. The photo shows the "severe stage" of dry air damage. Most often, when the air humidity is not much higher than the norm, the matter is limited to dry tips of the leaves (in large plants, for example, dieffenbachia, scindapsus), and in small-leaved plants, in addition to drying a few leaves.

If the ground was waterlogged, then at the same time a very wet earthy clod, yellowed lower leaves. In addition, if measures are not taken, the leaves lose their color, become lethargic and translucent, then rotting of the roots, stems and the death of the plant begins - this is when the plant is flooded. Very often, when waterlogged, the leaves suddenly turn yellow and fall off. Waterlogging of the soil, coupled with high air humidity, is dangerous because crusty growths appear on the leaves of plants - a disease called dropsy.

If the plant is dehydrated, then the earthen lump is overdried, the leaves lose turgor, the leaves dry up and fall off. If the soil is very dry, then watering can be difficult, because water will not absorb well. In this case, it is best to immerse the entire pot in a bowl of warm water until the soil is moist.

Sunburn is another common problem. Not all plants tolerate direct sunlight, with prolonged exposure to the sun, burns appear on their leaves, the degree of damage depends on the time spent in the sun. If this happens, you can only remove the damaged leaves and continue to shade the plants in hot, sunny hours.

lack of light
lack of light

The upper leaves remain firm, but turn yellow. Most likely this is an increased content of calcium in the soil, which is characteristic of some plant species. Water the plant with softer water, such as rain or melted snow.

The leaves turn yellow and fall off. The natural change of leaves is typical for most plants, but if they fall in large quantities, then this is most likely due to waterlogging of the soil or cold draft.

Old leaves turn yellow - in summer due to lack of macronutrients or dryness, in winter - due to lack of light or high temperatures at night.

Dots or spots on the leaves.

If the dots or spots on the leaves are dry, then most likely this is from a lack of water, if they are soft, it is due to waterlogging of the soil.

Light spots on the leaves - the likelihood that the plant has either been watered with too cold water, or has received sunburn, or is damaged by disease or pests.

If the spots on the leaves are weeping and swollen, then this is a disease (see diseases)

The leaves roll up and fall off. This happens when there is a lack of heat, waterlogged soil, or if the plant is caught in a cold draft.

Curling and wrinkling of leaves can be caused by the sudden action of chlorine, with a lack of magnesium, potassium, fluorine in the soil - in old leaves; the young have a lack of molybdenum, boron, copper, magnesium.

The sudden fall of leaves, when they do not even have time to turn yellow, is usually associated with the shock state of the plant, caused by an abrupt change in some conditions (this happens during acclimatization, a plant has just been bought), a sharp temperature drop, watering with cold water, cold draft, a sharp increase in the intensity of lighting in the daytime. Sudden leaf fall in arborescent plants (such as citrus) can be caused by drying out of the soil.

Brown edges and tips of leaves
Brown edges and tips of leaves

Brown tips or edges of leaves. If they are dry, then the most likely cause is too dry air, it can also be the result of physical damage, for example, in contact with glass. If the edges of the leaves are yellow or brown, then this may be due to waterlogging of the soil or lack of watering; too weak or too strong lighting; too high or too low air temperature; excess minerals, dry air, or cold draft. And it can also be when a plant is poisoned with chlorine or potassium starvation. Other symptoms will help determine the true cause.

The stems of the plant are bare from the base - with an acute lack of lighting. Normally leafy in this case, only the tips of the shoots can remain. This can happen at any time of the year and if it is not possible to rearrange the plant closer to the window or to the window sill, then additional lighting will have to be connected. Otherwise, the plant may die.

  • Drooping leaves - when the soil is dry or waterlogged, with an excess of light, especially if the leaves droop at a certain time of the day, when the sun is most intense. Leaves drooping can also be caused by dry air or pests. In addition - a chronic acute lack of potassium, magnesium, copper, excess calcium or hard water. In some plants, this happens due to a sharp change in location.
  • Buds or flowers fall off most often due to dry air, lack of light, insufficient watering, when the plant is rearranged from place to place and when damaged by pests, as well as with an excess of nitrogen. Flowers fade quickly with a lack of watering, dry air, lack of light or too high an air temperature, excess nitrogen and general starvation.
  • The lower leaves dry out and fall off, most likely due to a lack of light, or too high an air temperature, or a lack of watering.
  • Leaves become pale - mostly in too much light, and can also be caused by spider mites.
  • The tips of the leaves turn yellow - excess calcium, insufficient watering.
  • Yellow-brown color of leaves - watering with hard water or chlorinated water.
  • Pale green color of leaves to whitish, mosaic of leaves - a lack of iron, copper or sulfur in the soil.
  • Light green leaves, and the veins on them are green - an excess of chlorine or calcium in the water; general starvation with a lack of nitrogen and iron; inadequacy of soil acidity; root disease; root damage by a nematode; in summer, this happens with an excess of light.
  • Variegated leaves become monochrome green - with a lack of light or with an excess of nitrogen in the soil.
  • Leaves and stems rot - with diseases caused by poor conditions, most often waterlogged soil.
  • Vitreous discharge on the leaves, brown, partially dry spots - unfavorable moisture conditions, excessive watering, high humidity, lack of fresh air, low temperature or lack of light.
  • The plant grows slowly or not at all. For all plants, there is a dormant period in autumn and winter, when it does not grow or grows, but very slowly.

    If this happens in spring or summer, then the reason may be a lack of minerals, and insufficient lighting, and waterlogging of the soil.

  • Elongated stems with small leaves - this phenomenon is more often observed in winter or early spring due to lack of lighting at too high an air temperature. If the stems are pulled out in the summer during the growth period, then most likely this is a lack of minerals or a lack of lighting.
  • The plant does not bloom. In general, the flowering of plants is such a difficult thing - some bloom even with poor care, while others, no matter how hard you try, do not bloom and that's it. But most often it is still due to lack of lighting or short daylight hours. Other reasons may be a violation of the dormant period, excess minerals, dry air, thrips (dinner buds) or transplantation (some plants bloom only in a cramped pot).
  • Short peduncles - irrigation regime is violated (excess or lack of moisture), improper feeding regime, lack of fluoride, general starvation of the plant, late transplanting in autumn, inconsistency of the soil mixture for this plant, strong temperature fluctuations, excess heat during bud growth, incorrect content during dormancy …
  • Green bloom on a ceramic pot or on the inside of a plastic pot is a sign of waterlogged soil (usually due to poor drainage).
  • White crust on a ceramic pot or on the surface of the ground - with an excess of minerals or watering the plant with too hard water.

If you find any of the signs listed above, then in order to finally determine what caused this condition of the plant, look in the encyclopedia and re-read the care tips. As you have already noticed, the same condition of a plant can have many different reasons, sometimes it is generally impossible to find out why the plant is suffering (for example, viral diseases are very difficult to determine), but knowing the conditions that the plant needs will greatly facilitate the determination of the cause. …

Sometimes the plant is simply forgotten to transplant in the spring, but it is recommended to transplant it every year. In general, this is a very common mistake of indoor florists - to forget to transplant the plant when it should be. Many do not consider this necessary, or instead of transplanting they feed the plant, which is wrong. And some transplant plants into completely unsuitable land for him.

If you have not found the answer to the question: why do the leaves of your plant turn yellow, then we suggest you ask it on the "Diseases and Pests" forum in the topic "Collecting a collection of diseases and pests".
