Why do geranium leaves curl. Ambulance for geraniums: what to do if the leaves turn yellow

REASONS WHY GERANIUM LEAVES CURL If the leaves curl from below, then the geranium lacks such an element as nitrogen. Nitrogen is considered very important chemical element in plant life. Nitrogen is involved in many chemical processes, and, thanks to this element, the plant has beautiful and lush foliage with rich green color. If there is not enough nitrogen, then the plant looks unimportant. However, an excess of nitrogen also negatively affects the plant, especially the flowering one. As a result, the plant begins to grow fat, leaves will actively develop, but there will be no flowers at all, or very few. Often, leaf curl can begin due to an excess of potassium. This substance is vital for the plant, because thanks to it the plant receives nutrition and has the opportunity to stock up on the necessary substances. But an excess of potassium is harmful. Lack of light Geraniums can start curling their leaves for other reasons as well, such as light. Many books on floriculture write that geraniums tolerate direct sunlight. However, from my own experience, I want to say that this is not always true. It is better to provide the plant with diffused light. By the way, the leaves can curl from dry air and high temperatures. Geranium, however, loves coolness more than heat. Improper watering Watering can also play a role, both good and not so good. For example, if a geranium lacks moisture, then its leaves begin to curl, which delays the evaporation of moisture. Due to the constant overflow, problems can also begin, because due to excess moisture, the earth is compacted and almost no air enters the roots. Geraniums need to be watered only when the top layer of the earth dries out. After watering, try to loosen the ground. Pests Most dangerous reasons leaf curl is a disease and pest. If you notice that something is wrong with the leaves, be sure to inspect the plant carefully from all sides for signs of pests (mites, for example). All these living creatures settle on flowers and begin to suck all the juice out of them. Fortunately, today you can get rid of pests, as there are powerful drugs on sale. It is enough to process the plants several times and there will be no trace of insects. True, getting rid of ticks is a little more difficult, since their larvae are very tenacious and begin to develop in favorable conditions. Diseases The most unfavorable cause of leaf curl can be a viral disease. Unfortunately, getting rid of viral diseases is very difficult, sometimes even impossible. It is often best to get rid of plants to prevent the spread of infection. Not only twisted leaves speak of a viral disease. There are also symptoms such as ugly flowers, they look like torn ones. And the leaves become curly and even young. Sometimes the leaves can curl because the pot has become cramped, in which case the plant needs to be repotted. If you took soil on the site for planting geraniums, then perhaps it has earthworms, which can cause leaf curl, or larvae of other living things. In this case, the plant will have to be transplanted. Now you know why geranium leaves curl. There may be more reasons, but I only know these, if you know other reasons, I will be glad if you share them.

There can be many reasons why geranium leaves curl, and this is not always due to illness. Often the cause of this phenomenon can be ordinary starvation, or rather, lack of nutrition. To understand the reason, you need to carefully examine the plant and understand exactly where the leaves are twisted, at the top, or at the bottom.

Why do pelargonium leaves turn yellow A simple and at the same time unusual plant is geranium, ...

Hello my dear friends! I know how bitter it can be when your favorite plants start to hurt. BUT…

Geranium, (or kalachiki, pelargonium), is one of the most popular plants among flower growers. Her lush and bright umbrellas decorate window sills for almost a whole year, and in summer flower beds and balconies are often decorated with pelargonium. Despite the well-known unpretentiousness of the plant, sometimes the question arises: why do the leaves turn yellow in room geranium And how can I make her look healthy again?

Why do room geranium leaves turn yellow: the main reasons

It is no secret that in most cases the reason why the leaves dry and turn yellow in indoor plants, is the wrong care. If the situation is not corrected, this can ultimately lead to the complete death of the plant. Therefore, you should study the typical shortcomings in growing geraniums at home.

Errors when planting and transplanting a plant

Sometimes the reason why geranium leaves turn an unhealthy yellow color and begin to die off gradually is the wrong pot. If its size is too small for the root system (especially in plants whose age is several years old), then the pelargonium does not have enough capacity for development. But should not choose too big pot: in this case, the active growth of the roots will begin at the geranium to the detriment of the green mass and flowering, which is also undesirable.

When planting a plant, it is important to make good drainage. Perfectly fit bought in flower shop or the economic department of the expanded clay supermarket. If there is not enough drainage, then excess moisture will not leave the soil. Also, proper air circulation will be disturbed. In some cases, the yellow color of the leaves provoke damage to the roots during inaccurate transplantation.

Lack of minerals

stock minerals in the soil is a resource that is rapidly depleting. Yes, and immediately after transplanting into a new soil, the elements in it are not always contained in the required quantities. But Geranium expends a lot of energy on flowering and growth. Therefore, there is a need for additional and regular introduction of mineral complexes into the soil by root feeding. The need for them increases during the growing season, when pelargonium is actively growing and blooming. The lack of minerals often leads to the fact that the leaves turn yellow. But it is important to remember that an excess of elements will also adversely affect the condition of the plant.

Improper care at home

As already said, geranium is a fairly unpretentious home flower, feeling good in the room. But in order for diseases and yellow leaves not to appear, it is necessary to try to provide it with suitable conditions in which the plant will feel comfortable.

Pelargonium loves light, but direct sunlight is detrimental to its leaves. Can do a lot of damage appearance plants low and excessive humidity in the room. Its optimal rate is 50-60%. Geranium dries in cool drafts. In autumn and winter, it is advisable to keep the pot away from heaters in the apartment - the heat from them will make the leaves turn yellow and dry. It is better to take it out to a cool glazed balcony if the temperature in the loggia is kept around 12 ° C, reducing watering to 1 time per week.

Another common mistake is related to watering. Its frequency should depend on the time of year: in the warm months, geraniums should be watered more often. You should also pay attention to the quality of the water. If it is too hard, it will lead to excess calcium in the soil. The leaves will react to this and turn yellow. To make water suitable for irrigation, it must be defended for several days; add a couple of drops of lemon juice or a small pinch of citric acid.

How to care for geraniums (video)

What to do if geranium leaves turn yellow

The plant can be saved if timely action is taken. necessary measures. First of all, you should:

Make sure the pot is suitable for the geranium and has good drainage. If necessary, it is necessary to transplant as soon as possible into a dish that meets all the criteria. If the geranium blooms, then all flower stalks must first be carefully cut.
Place the pot on the sunny side. If direct rays fall on the plant, you will need to create temporary artificial shading. It is important that the pelargonium does not stand in a draft.
Avoid exposure to geranium heaters.
If possible, maintain an acceptable temperature in the cold season. In the remaining months, there are no strict recommendations in this regard.
If the air is too dry, you can put a container of water or moistened expanded clay next to the pot. Florists do not recommend spraying.
Adjust watering and fertilizing plants. It should receive enough water and minerals. But overflow and excess of elements are also destructive.

In caring for pelargonium in an apartment, it is best to follow the golden mean rule. If the mistakes described above are corrected in time, the flower will not disappear and recover quickly, delighting with carved green leaves and abundant flowering.

Pelargonium: other diseases and care errors

Geranium leaves speak for the health of the whole plant. This is a kind of indicator that can indicate possible diseases pelargonium, the wrong scheme of watering and fertilizing. There are some specific "symptoms" that can tell a lot.

Dry edges of geranium leaves

If the edges of the leaf plates began to dry at the geranium, then there can be two reasons for this condition:

The plant receives insufficient moisture. Usually such drying is observed if the pot is in a very hot place. It is better to rearrange the geranium in partial shade.
The root system of pelargonium suffered. You can try to transplant the plant by treating the roots with a weak solution of potassium permanganate. But for safety reasons, it is better to cut and root the cuttings in water or soil so as not to lose the variety.

Leaves curl inward

If the leaves of pelargonium began to twist inward, then this may be evidence of an imbalance in minerals. This condition is caused by a lack of nitrogen or an excess of potassium. Nitrogen in large quantities is needed only in the stages plant growth, therefore, the leaves of young plants are often curled. In order to prevent deficiency or oversaturation of elements, it is recommended to use ready-made complex mineral fertilizers for flowering plants: the substances in them are in the right proportions.

Often, pests become the cause of twisted leaves at the edges. Most often - spider mites. To detect it, you need to examine the leaf plates of pelargonium from all sides. It is advisable to use a magnifying glass. The tick is easily treated chemicals- insecticides. It may take several treatments.

Much more dangerous than a viral infection. With it, the inflorescences also acquire a clumsy, ugly shape. In this case, it is unlikely that it will be possible to save the geranium. It should be thrown out of the house to prevent the spread of infection to other houseplants.

Pelargonium wilts in a pot

If the geranium wilts in a pot and slowly dies, then the reason lies in the root rot. This disease can easily destroy the plant. Such pelargonium is usually thrown away, cutting off healthy cuttings for further rooting. Tools must then be disinfected. To avoid root rot, you should try not to flood the plant and make good drainage.

Blackening geranium leaves

Geranium leaves turn black with improper care. Dry spots are associated with insufficient moisture, and “wet”, slippery to the touch, on the contrary, with its excess. Sometimes mealybugs are the cause of black spots. The plant infected with them begins to throw off the leaves. Sooty fungi form at the places of life of the worms, due to which a black coating appears. This disease is treated with insecticides.

white patches on the plant

The leaves are getting smaller

Pelargonium leaves inevitably shrink with age. If the plant is too old, then cut off its freshest shoots for further rooting. Other causes of small leaves in pelargonium may be:

nitrogen starvation (you must additionally add a substance in the form foliar feeding);
low humidity in the room;
high air temperature.

Pelargonium leaves turn yellow and dry: preventive measures

It is much easier to prevent yellowing of the leaves than to cure an already diseased plant. In order not to have to fight to save your beloved geranium, you should:

Transplant pelargonium in a suitable pot in time.
Find a place for her, closed from drafts, with a sufficient amount of diffused light.
Water as the earthen coma dries out.
Apply mineral complex fertilizers suitable for flowering plants in time. The application rates and schedule are indicated in the instructions for the product. During the flowering period, it is recommended to do root top dressing twice a month. Organic fertilizers will also be useful.
AT winter time you need to try to provide geraniums with coolness.
Regularly inspect the plant for infestation by pests, bacteria, fungi and viruses, providing treatment if necessary.

Yellowing of geranium leaves is an alarming sign. It is important to understand in time the cause of such an ailment of the plant. After carefully examining it and analyzing the conditions for keeping pelargonium, you can find what provoked such a reaction. The sooner the errors are corrected, the less harm will be done to the geranium.

Florists often observe a picture withered or yellowed leaves on your pets. It often happens that yellowed foliage turns out to be natural phenomenon tissue death. But it also happens that the wrong care is to blame.

For lovers, such dying off of yellowed leaves happens regularly. How to help and how to save geraniums, we will write in this review.

If geranium leaves begin to dry, turn yellow or curl, you should understand the reasons for the violation of the care of a houseplant to save him from death in the future.

Classmates

Mistake one - the wrong flower pot

Each plant requires choose the right container. Geranium in the case of a cramped flower pot will be deprived of the opportunity to develop and grow normally.

Too much capacity will also be inappropriate, this will contribute to the growth of a large root system to the detriment of active flowering and green mass.

Mistake two - improperly organized transplant

In addition to the competent selection of the container, it is also important to select the nutrient soil and organize the drainage layer. As a drainage, it is recommended to use a special tool - expanded clay. It is purchased in flower shops. Thanks to expanded clay, excess liquid will not linger in the pot when the owner waters his pet. And also the root system will be available Fresh air. Inaccurate transplantation can also cause wilting and yellowing of the foliage if the root system is damaged.

If premature transplantation occurred during the flowering period, flower stalks are removed from the plant for successful rooting.

Mistake three - depleted soil

In the event that the plant is already quite mature and has not been transplanted for more than 3 years, it soil is depleted, devoid of useful trace elements. Pelargonium during flowering absorbs a significant supply of mineral elements from the soil. If at the vegetative moment the necessary complex is insufficient, this will affect the condition of the geranium foliage and the scarcity of its flowering.

Mistake #4 - Wrong Care

Despite the fact that geranium is considered unpretentious, non-compliance with its basic requirements for care may lead to death.

geranium especially needs to sunshine , but direct rays, like most of plants, she tolerates with difficulty. Therefore, yellow spots on pelargonium leaves may appear as result of sunburn.

The next important parameter for "kalachiki" is air humidity. The optimal humidity indicator for pelargonium is 50-60%. If the humidity level is exceeded, after a while the plant will let you know. If the leaves of the geranium have turned yellow, it will become clear why this happened in a hot or too humid room.

In autumn, the plant should be protected from drafts and a sharp cold snap. Dry leaves on the plant may appear as a result of exposure to cool air currents. With the onset of the autumn-winter period, the irrigation regime is also subject to adjustment. At this time, water should not be allowed to stagnate in the container. Also, do not water pelargonium during the season of lower temperatures.

It is necessary to protect the plant from one more "trouble" - from too hot and dry air coming from the heater. The indoor plant must be removed from the flow of warm air at a safe distance. It is useful to know that geranium prefers a temperature of 12 degrees to a greater extent than too dry air in the apartment. Therefore, the plant can be safely taken out to the glazed balcony in the autumn before a significant cold snap sets in.

Irrigation water quality also matters. If there is a high content of calcium in the liquid, this will inevitably affect the condition of the plant, and the foliage may turn yellow. To prepare water for irrigation, it is recommended to keep it for a couple of days and change the chemical composition by adding a small amount of citric acid or a couple of drops of lemon juice.

Signs and causes of problems in geraniums

The foliage of a plant is almost always calling card condition of a pet. If it begins to dry, turn yellow or fade, then there are problems or care recommendations are not followed.

If the edges of the foliage dry in pelargonium

If a dry border is found on the foliage, one of two reasons should be eliminated:

plant stay under the aggressive rays of the sun;
damage to the root system.

In the first case, it is enough to move the container with pelargonium to openwork penumbra.

In the second case, it is necessary to transplant into fresh soil with a drainage layer and root processing. If the condition of the plant causes concern, it is recommended to play it safe and cut the cuttings for subsequent rooting.

The reason for the appearance of a dry border on the foliage of geraniums in most cases is the lack of moisture in the soil or the surrounding air.

If geranium leaves curl inward

First you need to figure out why geranium leaves twist inward. One of the reasons why this happens is a violation of the mineral balance. The first reason is the insufficient content of nitrogen in the soil, which can be replenished by applying organic fertilizer. Another reason could be too much potassium. In order not to return to such a problem in the future, it is recommended to use mineral-based complex fertilizers. To do this, it is enough to water the plant with the addition of a concentrated mineral complex.

In the event that the plant is regularly fertilized taking into account the season, watering is carried out on time, pest attacks can be the cause of twisted foliage. For example, a spider mite, which is easy to detect by turning the leaf. One or two insecticide treatments will be enough to save the plant.

Another cause of wilting and yellow foliage on geraniums is a viral disease that is difficult to treat. You need to get rid of such pelargonium in as soon as possible to keep the infection from spreading.

If an unsatisfactory condition (withering with a yellow leaf) of geraniums at home is found, rot on the roots can be suspected first of all. In this case, cuttings are taken from the plant, the tools and the container are processed after the diseased plant, and its remains are thrown away.

Why do black spots appear on geraniums?

If black spots are found on the foliage of pelargonium, one can also judge the overflow of the home flower and its death. Dark spots can also be a consequence of the presence of mealy worms. If these insects exist, insecticidal formulations are used.

Preventive measures against the appearance of yellow foliage

With plants, as with humans, diseases are easier to prevent than to cure. Therefore, it is recommended to take preventive measures.

Practical preventive tips for caring for geraniums:

transplant every 3-4 years in a suitable size container;
transplant in accordance with the recommendations for the soil, processing, if necessary, the root, and the organization of the drainage layer;
carefully select a suitable place for a houseplant at home;
moisten as needed (check the humidity of the earthen coma);
during the growing season provide regular top dressing;
compliance with recommendations on the microclimate for pelargonium;
regular examination for the presence and provision of timely treatment.

Actions when yellow leaves are found in geraniums

To begin with, the plant is subjected to inspection and analysis of the causes of the appearance of yellow leaves. Next, the foliage with a dry border or spots is cut off. Then they act as necessary and eliminate the cause of damage to the plant.

As an ambulance for geraniums, you can apply watering with a weak solution with the addition of iodine.

Periodically, when watering, experienced flower growers recommend adding a couple of drops of wine during watering for active growth and development of the root and ground parts of the geranium.

Geranium lovers have noticed that pelargonium will fully open when watered. warm water with a couple of drops of wine and obligatory pruning in February.

Yellowed bottom sheets and an elongated trunk will indicate a lack of lighting. To change the situation, you can pinch the top, rearrange the geranium closer to the light and continue to wait for frequent flowering.

Sunburn is manifested by yellowing, then drying and death of the leaf. The solution to the problem is simple - remove from direct sunlight deep into the room.

To make sure that the geranium does not suffer from waterlogging, you can use a wooden skewer, which should be stuck into the ground to the very bottom for 20 minutes. When the skewer is removed from the soil, it will clearly show how deep the soil has dried out. The best option is to loosen the soil before each watering, which is done as needed and thrown to extremes.

We hope this review provides answers to questions about why geranium leaves begin to turn yellow, what conditions it needs to provide and what to do to help the affected plant.

Are the leaves of your favorite geranium turning yellow and drying? This means that you are not properly caring for the plant or that it has been attacked. dangerous pests or disease. Below we have listed all possible reasons yellowing of pelargonium, as this is also called beautiful flower, as well as methods that will help quickly bring the plant back to life.

plant care mistakes

The main reason for the loss of attractiveness of indoor plants is improper care. If your geranium in the apartment also began to turn yellow and dry, be sure to check out the list of factors that are unfavorable for flower development:

Insufficient or bright lighting

Geraniums love to live on a windowsill, which receives plenty of daylight during the day. Therefore, if the flower does not have enough light, its leaves may turn yellow. But keep in mind that pelargonium is also intolerant of direct sunlight, under the influence of which yellow or brown burns may appear on the leaves of the flower.

Too much watering

This is the most common cause of yellow leaves on a geranium bush, as this flower does not like excess moisture. Geranium is a drought-resistant plant that needs to be watered no more than once a week (you can increase the frequency of watering only in hot summers).

Lack of regular watering

Room geraniums have a very bizarre character, because from a lack of moisture, it can behave in the same way as with its excess. Therefore, it is important to water the flower every time the soil in the pot dries out by 2.5 cm. To increase the time between watering, use mulch (it can be marble chips, crushed stone, synthetic materials, pine bark, peat, tea, moss).

The wrong soil

For good growth, geranium roots need loose, fertile soil. Flower growers recommend buying a substrate for her in a store, and not digging in the yard. In ordinary sand or loam, the flower will show poor growth.

High air humidity

An excess of moisture can be felt by the plant not only by the roots, but also by the leaves. Therefore, do not spray geranium leaves - this can make it turn yellow.

Heat

Geranium shows the best growth at + 20 ° C, while at more high temperatures its leaves may turn yellow. More often this happens in winter, when the air temperature in the room rises from the battery under the windowsill on which the flower stands.

hypothermia

Pelargonium can turn yellow even when too low temperatures, because when hypothermia begins the natural process of the death of the flower.

Lack of feeding

For fast and active growth, geraniums need nitrogen, phosphorus, potassium and iron. Top dressing should be applied along with water during every third watering or once a month. As a top dressing, choose a universal fertilizer for indoor plants with a minimum amount of nitrogen.

herbicides

If the leaves of a geranium are turning yellow and slowly drying around the edges, try to remember if they have been exposed to herbicides for weed control or other chemicals. Leaves of plants can change color even after being exposed to drops of air freshener.

small pot

If the root system of the flower exceeds the volume of the pot, the plant will not receive the right amount nutrients(and possibly moisture). Increase the volume of the pot gradually, otherwise the plant will throw all its strength into building up the root system and stop delighting with bouquets of flowers. The diameter of the new pot should exceed the diameter of the old one by only 2 cm.

drafts

If your geranium is standing on a window that opens for ventilation even in autumn and winter, the leaves of the plant will turn yellow all the time. But as soon as you rearrange the pelargonium pot away from drafts, it will immediately change.

Lack of drainage

A layer of drainage must be present in a pot with geraniums in order to remove excess moisture from the roots. Otherwise, the roots of the flower may rot, and with them the whole plant may gradually rot.

Diseases accompanied by yellowing of the leaves

If you take good care of geraniums, but its leaves turn yellow anyway, you should look for one of the following diseases in the plant:

Gray rot

Except for the yellowed leaves, gray rot can provoke the appearance of gray rot leaves with a velvety coating along the edges. To get rid of it, try planting geranium bushes and put the pot in a lighted place. Remember to remove diseased flowers and leaves, and sprinkle ashes on the affected areas.

Alternariosis

The presence of yellowness and brown spots with a light center - clear sign alternariosis. At high humidity, spots can become covered with a brown coating. What to do with such a disease? Let the soil in the pot with the flower dry out in the sun and treat it with fungicides.

Rhizoctonia rot

Affecting the roots and stems of the flower, one of the consequences of such rot can be the yellowing of geranium leaves. You can recognize the problem by dark depressed spots on the stems, along which the fungus begins to multiply over time. gray color. To save the flower, stop watering and treat it with fungicides.

verticillium wilt

The first sign of this fungal disease is the yellowing of the lower leaves of the geranium. Progressing, verticillium wilt completely destroys the plant. You can overcome the fungus only by removing the yellow foliage and treating the soil with fungicides. In case of severe damage, it is better to throw the plant and soil away.

Rust

The first sign of rust is brown dots on the stems, after which the leaves of the flower may begin to turn yellow and fall off. When infected, the flower should be transferred to a dry room, reduce the intensity of watering and treat with fungicides.

Pelargonium pests

whitefly

Pelargonium has a weak immunity to the whitefly, which likes to settle under the leaves of the flower and lay its larvae there. If the pest has time to create a large colony on the geranium, the leaves of the plant may turn yellow or brown. You can recognize the whitefly by its characteristic white wings and a small body length - up to 2-3 mm.

A soapy solution will help get rid of the larvae and adults.

Aphid

If the geranium leaves curl inward and turn yellow, it is most likely attacked by aphids. To get rid of it, regularly cut off and burn the affected leaves, and wash the flower itself with a solution of ash and soap.

What to do if the leaves of room geraniums turn yellow?

To restore the attractiveness of a geranium flower and stop the yellowing of the leaves, use 6 rules:

Transplant the flower into a larger pot. When transplanting, use good quality soil and don't forget about drainage.
Move the pelargonium pot to the sunny side of the house, where there are no drafts. Remember to create artificial shading from direct rays.

Remove the plant from heaters.
Maintain the air temperature in the pelargonium room at 20°C.
If the air in the apartment is dry, place a container of water next to the flowers, but do not spray them.
Maintain regular watering and fertilizing.

Geranium loves moderation in temperature, watering and even light. Given these factors, you can very quickly return the flower to attractiveness and abundant flowering.
