Causes of leaf fall in indoor lemon

Lemon is a hybrid type evergreen citrus plant. Indoor cultivation is done for fruit and for decorative purposes. The plant is whimsical to growing conditions, but has resistance to disease. If the leaves of lemon fall, this is a symptom of a violation of the rules of care.

Causes of leaf fall in indoor lemon

Causes of Foliage Loss

Indoor lemons lose their green leaves for the following reasons:

  • insufficient lighting;
  • excessive soil moisture in the pot;
  • lack of sufficient nutrients in the soil;
  • dry indoor air;
  • oversupply of fertilizers;
  • incorrect transfer to a new container;
  • insufficient amount of water;
  • low ambient temperature;
  • a sharp change in the place of cultivation;
  • temperature differences.

Lemons are semi-deciduous plants. Loss of foliage in winter is not a natural process, but a symptom of the influence of external factors on the plant. The presence of one problem causes small losses of leaves and their yellowing. If the leaves of lemon fall, then there are several negative factors.

Light effect

One of the most common causes of foliage falling in house trees is improper lighting. The main time of lack of light for a lemon is winter. During this period, the fruit needs more ultraviolet light, because the air in winter is cold and less humid.

Rules for lighting a lemon in winter:

  • Location The plant feels better on the windowsill from the south or east. It is forbidden to grow room lemon near heating appliances: they will cause drying and loss of foliage.
  • Using mirrors. So that the leaves do not dry, they are placed around the plant. So they reflect the sun's rays. As a result, the lemon receives a sufficient amount of ultraviolet radiation.
  • Lighting. If it is not possible to provide room lemon with natural light, use artificial. For this, the plant is illuminated with special ultraviolet lamps or daylight devices.

If the lemon dropped its leaves in the warm seasons, change its place. A window sill is chosen, which is exposed to direct sunlight for at least 3 hours a day. In summer, the plant is taken out to the terrace or balcony.


Homemade lemon drops leaves due to excessive watering. This causes stagnation of water in the soil, waterlogging occurs. The soil is not loose enough. The roots do not receive the required amount of oxygen. This causes stress in the plant, which is determined by the fact that the leaves have fallen.

As a result of waterlogging, roots and capillaries die off in a houseplant. The nutrition of the roots is deteriorating, which affects the state of the crown of the tree. New shoots are not formed, and there are not enough useful elements to maintain the old ones. Leaves begin to turn yellow and fall. Waterlogging also causes the appearance of fungal diseases of roots and tree branches.

Lack of moisture

A small amount of moisture also adversely affects the lemon. Drying and curling of the leaves is a symptom of the drying of the soil layer. Dead leaves of home-grown citrus fruits gradually fall off, and there is not enough moisture to develop new ones.

With a lack of moisture, the roots of their end die off. The circulation of juices in the trunk and branches worsens, the plant enters the stress stage and dies. Flowers and ovaries do not appear.

To restore the condition of the lemon. if the leaves are dry, restore watering. You can’t drastically introduce moisture into the dried soil: this will lead to an excess of water in the root system and, as a result, to the disease.

The lemon tree is resuscitated gradually. Before watering, foliage is sprayed so that the crown is saturated with moisture. Then gradually introduce moisture into the soil. Its amount is increased with each new application, until the lemon is in a normal condition.


Spray the plant regularly

Young citrus requires constant spraying of the crown under normal conditions. A suitable temperature for the development of a houseplant is 18 ° C-20 ° C. In the hot season, plants are sprayed 2-3 times a week.

In winter, the number of procedures depends on the power of the heating devices. If the air is warm, and the plant dries and takes off the leaves, spraying is carried out daily. At a cool temperature, 2-3 procedures are performed per week.

If moisture is not applied on time and the air is dry, the leaves fly around. To revive it, the plant is regularly treated. Also room lemon is put away from heating appliances or covered with a cloth during the day. Lack of moisture will stop buying a humidifier.

Cold air

In winter, lemon feels normal at a temperature of 12 ° C-14 ° C. With colder air, the plant discards leaves. It is forbidden to grow lemon in the winter on an unglazed balcony or street.

To restore a plant, it cannot be sharply brought into heat. Lemon does not tolerate sudden changes in temperature, and therefore will lose even more leaves from the crown.

Room temperature is increased gradually. During care, carefully monitor the condition of the leaves and shoots. If they look better, the temperature is slightly increased. Also, the tree is protected from drafts.

Soil depletion

Soil for growing lemons should contain:

  • zinc;
  • potassium;
  • cobalt;
  • iron.

Also, the plant requires regular application of phosphates and natural fertilizers from humus, deciduous land, peat and ash. They are needed for the active growth of shoots, maintaining the crown, the appearance of the ovary and fruits.

Signs of a lack of nutrients in the soil:

  • the appearance of yellowness on the leaves;
  • withering of the crown;
  • sheet shape change;
  • drying of the shoots.

If you do not saturate the soil with minerals in time, the tree will lose foliage, and the fruits will stop developing. So that the bush does not drop the foliage, top dressing begins to be applied regularly.

In the summer, 2 times a month make mineral fertilizers and organic substances. In the cold seasons, top dressing is applied once a month. If the tree does not bloom, phosphorus is not introduced.

Pests and diseases

In lemons, the leaves fall and when infected with pests:

  • Scale shield. She feeds on the juices of the tree, which causes a lack of foliage. Symptom of the disease - small holes on the leaves.
  • Aphids. It feeds on substances from leaves, which causes them to wilt and dry. Identify by the presence of small black dots.
  • Spider mite. Appears during the flowering period. Determined by the web on the branches.

The action of pests causes the plant to dry out, its leaves crumble. For the fight, chemicals are used, as well as alternative methods. A decoction of garlic and onion peel helps a lot.

To get rid of aphids, green leaves are rubbed until they have fallen. Soap solution can also help with spraying.

Lemon leaves fall off due to fungal infections. They appear with an excess of moisture in the soil, affect the branches and root system. To revive the lemon, all affected segments are removed, the wounds are treated with growth stimulants. The plant is transplanted into new soil.


In order to prevent the death of a domestic plant, it is necessary to properly care for it. A healthy lemon has many fruits and blooms beautifully. When growing, it is forbidden to abruptly change the room. In summer, they monitor the night temperature.

To combat fallen leaves, prophylaxis is carried out so that he does not throw off the lemon. Also, a houseplant requires the formation of a crown and regular transplantation into a large capacity.
