Geranium is a houseplant known for its unpretentiousness and beauty. There are many varieties of this decorative culture (more than 400 species), which have spread throughout the world.

Unfortunately, like other plants, geranium has certain problems that arise during the life cycle of a plant if certain care rules are not followed.

Small leaves

Small leaves are one of the most common problems with geraniums and can be caused by a variety of reasons.

Why is this happening?

  • One of the reasons why the leaves have become small may be the small size of the container in which it is planted or poor drainage in it.
  • In the event that the pot is selected correctly and the correct drainage is arranged in it, but the leaves are still too small, you need to pay attention to the soil, it may have become impoverished.
  • In addition, if geranium has been growing for a long time and at this moment the flowering period is underway, it may be time to thin out its leaves somewhat.
  • Another reason may be an inconvenient temperature regime for geraniums - the plant does not like high and low temperatures.

What can I do to fix the problem?

There are several ways to solve the problem:

  1. change the pot to a larger one;
  2. change the microclimate in the room;
  3. improve drainage;
  4. replace the soil;
  5. carry out foliar feeding with nitrogen fertilizers;
  6. trim the leaves (no more than 1 time per year).

If you exceed the dosage of fertilizers, you can create a new problem - burn geranium leaves, so you must follow the requirements that the manufacturer indicates on the packaging of the fertilizer bag.

How to prevent crushing?

  • As a preventive measure, in order to preserve the decorative properties of the plant, it is necessary to carry out a regular annual image (the period of the end of the winter season and the beginning of the spring).

    Cut geranium stems can be used as seedlings, growing new plants from them.

  • The second option is to pinch the top of the plant, which will stimulate the growth of side shoots, which make the plant even more beautiful by increasing the "fluffiness".
  • In addition, it is recommended to regularly change the pot to a larger one to create a larger base for the crop roots and add rich new soil.

Little greenery

In that case, if the number of leaves on a decorative culture clearly does not correspond to the norm, do not rush to get rid of such a specimen - the problem is solvable, but first you need to find out the reason.

Why is this happening?

  • A careful examination of the plant should be carried out for the presence of parasites that may interfere with the natural growth of leaves.
  • In the event that insects are not found, it is worth paying attention to the acidity level of the soil and the composition and amount of dressings used.
  • Another reason may be not enough light for the plant's leaves to grow.

What can I do to fix the problem?

Depending on the diagnosed cause of the problem, it is necessary:

  1. change the soil;
  2. use top dressing within the recommendations on their packaging;
  3. put geraniums in a place with sufficient natural light;
  4. if insects are found, use special countermeasures - insecticides.

How to prevent?

As a preventive measure, it is necessary:

  1. conduct a weekly inspection of the plant in order to identify parasites;
  2. do not exceed the required amount of foliar dressing;
  3. put a pot of geraniums in a bright place;
  4. periodically turning it in different directions to the light source (but not to the bright sun).

Greenery does not grow

If geranium has a complete lack of leaf growth, then the issue must be resolved in a cardinal way.

Why is there no growth?

This problem arises in cases where the plant receives a small amount of light, nutrients, or the level of soil acidity is significantly below normal.

What should I do?

To solve these problems, you must:

  1. determine the level of soil acidity, if it is below 5.5 pH, it is necessary to increase it to 6.5 pH - in such a soil, soil nutrients will be available for geraniums;
  2. put the plant in a lighted place;
  3. use liquid fertilizers created specifically to improve the process of leaf growth, without exceeding the norms specified in the instructions.

Geranium leaf problems can be varied. We have prepared articles on why the leaves turn white, turn red or turn yellow, including at the edges and completely, as well as why spots curl or appear on the leaf plate and how to solve these problems.

How to prevent?

As a preventive measure, it is necessary:

  1. always place the plant in a place with good (but not excessive) level of natural light;
  2. carry out foliar dressing and watering on time.

Leaves and flowers fall

This frustrating process can be frustrating for any geranium owner, but there are a number of possible solutions to this problem as well.

Causes of the phenomenon

  1. The reason for this situation is most often the indoor microclimate that is inadequate for geraniums.
  2. Acute deficiency of trace elements necessary for the plant.
  3. Another reason may be parasites that eat the plant from the inside.

In all three cases, you should immediately help the problem plant.

What should I do?

Based on the problematic, the solutions are as follows:

  1. it is necessary to change the temperature regime (moderate temperature, geranium does not like heat or cold);
  2. the humidity in the room should be moderate (geranium does not like either high humidity or excessive dryness);
  3. carry out foliar feeding in order for the necessary trace elements to enter the ground;
  4. treat the surface of buds and leaves with a special bacterial spray against insects.

Preventive measures

It is not recommended to change the location of the geranium after the buds have already appeared, it is necessary to monitor the indoor microclimate and carefully examine the plant at least once a week for the appearance of parasites.

Turn black

Almost all problems associated with leaf diseases are caused by improper care, bacterial diseases are a rarity among them, but you should not forget about them, the most dangerous is gommosis.

Causes of blackening

Leaf blackening is caused by xanthomonas campestris, a bacterium that spreads in high humidity and high temperatures on infected cuttings. Visually, this is displayed in the form of blackened leaves, which begin to die off over time.

How to cope with an illness?

For the treatment of this disease it is necessary:

  1. remove blackened leaves and cuttings;
  2. stop watering and feeding;
  3. use fungicides to destroy the causative agent of the disease.

Preventive measures

As a preventive measure, it is imperative that:

  1. disinfect the tools with which grafting is carried out;
  2. provide geraniums with moderate watering;
  3. carry out high-quality drainage;
  4. place the plant in a place with good natural light.

Other diseases

The list of plant leaf diseases is not limited to those listed above, unfortunately, there are still many types of diseases.

There are fungal diseasesstriking this decorative culture. Most often, the fungus appears in conditions of high humidity, which can be caused by both excessive watering and the general atmosphere in the room where the geranium is located.

The fungus looks like a dark, fluffy bloom on the leaves and stems in the form of small spots that begin to increase in size over time.

For the prevention of this disease, it is recommended:

  1. clean the soil in the pot from foreign organisms and weeds;
  2. also watering directly into the ground above the roots, but not on the stems and leaves.

For treatment it is necessary:

  1. cut off all affected leaves;
  2. remove the top layer of soil and loosen the soil well;
  3. treat the plant itself with fungicides.

Most geranium diseases can be avoided if the care requirements and a number of preventive measures are met:

  1. it is necessary to provide the culture with good lighting;
  2. water moderately;
  3. make a simple drainage;
  4. it is also recommended to take out geraniums to the balcony or to the courtyard, or to ventilate the room well.

The result of all these actions will be an abundant flowering of a plant with a pleasant smell of fragrant essential oils, which will undoubtedly improve the atmosphere in an apartment or house.
