Geranium, (or feces, pelargonium) is one of the most popular plants among flower growers. Its lush and bright umbrellas adorn window sills for almost a year, and in summer, flower beds and balconies are often decorated with pelargonium. Despite the well-known unpretentiousness of the plant, the question sometimes arises: why do the leaves of room geranium turn yellow and how to give it a healthy look again?
Why leaves turn yellow at room geranium: the main reasons
It is no secret that in most cases the reason why leaves of indoor plants dry and turn yellow is improper care. If the situation is not corrected, this may ultimately lead to the complete death of the plant. Therefore, you should study the typical shortcomings in the cultivation of geraniums at home.
Errors in planting and replanting a plant
Sometimes the reason why the leaves of geraniums get an unhealthy yellow color and begin to gradually die out is an improperly selected pot. If its size is too small for the root system (especially in plants whose age is several years old), then pelargonium is not enough capacity for development. But too big pot should not be chosen: in this case, the geranium will begin active root growth to the detriment of green mass and flowering, which is also undesirable.
When planting a plant, it is important to make good drainage. Expanded clay bought in a flower shop or in the economic department of a supermarket is ideal. If there is insufficient drainage, then excess moisture will not leave the soil. The correct air circulation will also be disturbed. In some cases, the yellow color of the leaves provokes damage to the roots during an inaccurate transplant.
The stock of minerals in the soil is a resource that quickly runs out. And immediately after transplanting into a new soil, the elements in it are not always contained in the required quantities. But after all geranium spends a lot of energy on flowering and growth. Therefore, there is a need for additional and regular application of mineral complexes into the soil by root top dressing. The need for them increases during the growing season, when pelargonium is actively growing and blooming. A lack of minerals often leads to leaves turning yellow. But it is important to remember that an excess of elements will also negatively affect the state of the plant.
Improper home care
As already mentioned, geranium is a rather unpretentious home flower, feeling good in the room. But, so that diseases and yellow leaves do not appear, you must try to provide her with suitable conditions in which the plant will feel comfortable.
Pelargonium loves light, but direct sunlight is destructive to its leaves. Low and excessive humidity in the room can cause great damage to the appearance of the plant. Its optimal rate is 50-60%. Geranium dries in cool drafts. In autumn and winter, it is advisable to keep the pot away from heating appliances in the apartment - the heat from them will make the leaves turn yellow and dry. It is better to take it to a cool glazed balcony if the temperature in the loggia is kept at around 12 ° C, reducing watering to 1 time per week.
Another common mistake is watering. Its frequency should depend on the time of year: in the warmer months, geranium should be watered more often. Attention should be paid to water quality. If it is too hard, this will lead to an excess of 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 drops of lemon juice or a small pinch of citric acid.

What to do if geranium leaves turn yellow
The plant can be saved if necessary measures are taken in time. First of all:
- Make sure the pot is suitable for geraniums and has good drainage. If necessary, it is necessary to transplant as soon as possible into suitable dishes according to all criteria. If the geranium blooms, then all the flower stalks must first be carefully cut.
- You should put the pot on the sunny side. If direct rays hit the plant, you will need to create temporary artificial shading. It is important that pelargonium does not stand in a draft.
- Eliminate the effect on the geranium of heating devices.
- 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 near the pot. Flower growers do not recommend spraying.
- Adjust the watering and top dressing of the plant. It should receive enough water and minerals. But overflow and excess elements are also disastrous.
In caring for pelargonium in an apartment, it is best to adhere to the rule of the "middle ground". If you correct the errors described above in time, then the flower will not disappear and recover quickly, delighting with carved green leaves and plentiful flowering.
Pelargonium: other diseases and errors in care
Geranium leaves speak about the health of the whole plant. This is a kind of indicator that can indicate possible diseases of pelargonium, an incorrect irrigation and feeding scheme. There are some specific “symptoms” that can tell a lot.
Geranium leaf edges dry
If the geraniums began to dry the edges of the leaf plates, then there can be two reasons for this condition:
- The plant receives insufficient moisture. Usually this drying occurs if the pot is in a very hot place. It is better to rearrange the geranium in partial shade.
- The root system of pelargonium was affected. You can try to transplant the plant, treating the roots with a weak solution of potassium permanganate. But for safety, 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 the pelargonium began to curl inward, then this may be evidence of an imbalance in the mineral substances. This condition is caused by a lack of nitrogen or an excess of potassium. Nitrogen in large quantities is necessary only in the stages of plant growth, therefore, the leaves of young plants are often curled. In order to prevent deficiency or oversaturation with 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 leaves twisted around the edges. Most often - a spider mite. To find it, you need to examine the sheet plates of pelargonium from all sides. It is advisable to use a magnifier. The tick is easily treated with chemicals - insecticides. It may take several treatments.
Where viral infection is more dangerous. With it, the inflorescences acquire a clumsy, ugly shape. In this case, saving geranium is unlikely to succeed. It should be thrown out of the house to prevent the spread of infection to other indoor plants.

Pelargonium wilt in a pot
If geranium withers in a pot and slowly dies, then the reason lies in the root rot. This ailment 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.
Geranium leaves turn black
Geranium leaves turn black when improperly maintained. Dry spots are associated with insufficient moisture, and “wet”, slippery to the touch - on the contrary, with its excess. Mealyworms sometimes become the cause of black spots. A plant infected with them begins to fold leaves. Sooty fungi form at the earthworm sites, due to which a black coating appears. This disease is treated with insecticides.
White plaque on a plant
White plaque on geraniums is a sign of a spider mite. To get rid of it, you need to remove parasites from the plant, and then carry out the treatment with a special composition: a solution of acaricidal agent.
Leaves are fading
Pelargonium leaves inevitably fade with age. If the plant is too old, then you should cut off its freshest shoots for further rooting. Other causes of small leaves in pelargonium may be:
- nitrogen starvation (it is necessary to additionally add a substance in the form of foliar top dressing);
- low humidity in the room;
- high air temperature.
Pelargonium leaves turn yellow and dry: preventative measures
It is much easier to prevent yellowing of the leaves than to cure an already diseased plant. So that you do not have to fight to save your beloved geranium, you should:
- Replace pelargonium in a suitable pot on time.
- Find for her a place that is closed from drafts, with enough diffused light.
- Water as the earthen coma dries.
- Make timely mineral fertilizers suitable for flowering plants. The norms and schedule of application are indicated in the instructions for the tool. During the flowering period, it is recommended to do root dressing twice a month. Organic fertilizers will also be beneficial.
- In winter, you need to try to keep the geraniums cool.
- Regularly inspect the plant for infection with pests, bacteria, fungi and viruses, providing treatment if necessary.
Yellowing of geranium leaves is an alarming sign. It is important to understand the cause of such a malaise in time. After carefully examining it and analyzing the conditions of pelargonium, you can find what provoked such a reaction. The sooner errors are corrected, the less damage will be caused to geraniums.
