Indoor lemon: description and care at home


Pavlovsk lemon can be considered a symbol of Russian home citrus growing. History says that in 1860, the Nizhny Novgorod merchant Karachistov brought a lemon seedling from Turkey to the village of Pavlovo and planted it in a tub. Years passed, the lemon gave birth, and over time, almost every window in the village was decorated with lemon trees with golden fruits. That line of trees became known as Pavlovsk lemon.

But in fact, lemons were grown in tubs before. And not only in the greenhouses of kings and shahs - in Russia, it was rare that a landowner’s estate did not have its own greenhouse where lemons ripened.

It is believed that lemon arose as a result of natural hybridization of other citrus fruits. According to some sources, it is a hybrid of citron and bitter orange. Already in the 12th – 13th centuries, it was grown in India and Pakistan and quickly gained popularity in countries with tropical and subtropical climates. And the ability of lemon to adapt to closed ground today allows lemons to be grown even beyond the Arctic Circle.

Lemon (Citrus limon) from the Rutaceae family is an evergreen tree or shrub with thick shoots covered with sparse thorns. The leaves are oblong, oval-shaped, dark emerald green, glossy.

The flowers are single or paired, 2–3 cm in diameter, pure white or creamy white, strongly recurved, with a delicate aroma. The buds and outer side of the flowers are pinkish in color. Budding lasts about 1 month, and flowering lasts up to 1.5 months. The fruits are egg-shaped, yellow, with juicy flesh of greenish-yellow color, sour-tart taste, ripen 8-9 months after the end of flowering. Most varieties have seeds.

The leaves and peel of the fruit contain a large amount of phytoncides, thanks to which lemons growing at home improve the atmosphere of rooms, protecting against staphylococcus and E. coli, its essential oils increase human performance. By the way, among all citrus fruits, lemons and grapefruits purify the air the best. Oranges and tangerines to a lesser extent (1).

Fruits grown independently contain the maximum amount of useful substances. They strengthen the immune system and have a beneficial effect on the cardiovascular system. Water or tea with lemon is an excellent remedy against colds, vitamin deficiency and poisoning.

Lemons are grown outdoors in subtropical regions. However, this citrus has long been grown in tubs. Moreover, in the summer, these plants are traditionally taken out into the garden under the canopy of trees. It is important to return the plants to warm rooms in time, because during short-term frosts (-3 ° C) the shoots freeze, and the fruits are even more sensitive.

An adult tree in indoor conditions can produce 10 - 20 lemons.

Varieties of indoor lemon

To grow lemon at home, it is important to choose the right variety. The best option is varieties that have long been adapted for such conditions or specially created, which do not exceed 2 m in height and are shade-tolerant. If you have a choice, it is better to buy a seedling grown from a cutting, because sellers of grafted lemons do not always indicate the rootstock. And this is important, because these can be seedlings for open ground.

Traditionally, the lemon varieties grown in Russian homes are Pavlovsky, Meyer and Lunario. However, the range of lemon seedlings is wider, so you can choose the most suitable one for a particular living space. Particularly interesting are the remontant varieties, which bloom and bear fruit 2 to 4 times a year.

Pavlovsky. An ancient Russian variety with a rounded compact crown up to 1.5 m high. The fruits are large with thin smooth skin, juicy sweet and sour pulp and a large number of seeds.

The variety is early-bearing - blooms 3 years after rooting of cuttings, remontant, blooms 2 times a year - in spring and autumn.

Meyer. One of the best high-yielding varieties of Chinese origin with a rounded crown, up to 2 m high, relatively small leaves, multi-flowered inflorescences, round bright yellow fruits with thin shiny skin - they are very juicy, sweet and sour, with a special flavor.

The variety is remontant, blooms 4 times a year.

Lunario ( Four Seasons ). An ancient Sicilian high-yielding variety with a beautiful crown shape, barely reaching 1 m in height. Very characteristic fruits are elongated in shape with a pronounced neck and “navel”, thin smooth skin of light yellow color. The taste is weak, not very sour, but with a strong aroma. The pulp is slightly juicy.

The variety is remontant and blooms every new moon, so the tree almost always has ripening fruits and flowers.

Villa Franca. An American variety with oval smooth fruits, yellow juicy sweetish pulp and dense skin. It is distinguished by large emerald-colored leaves and a small number of thorns.

Genoa. Italian high-yielding variety up to 1.5 m high with a lush crown. The fruits are round and medium in size with a yellowish-green rough skin, juicy and aromatic pulp with a sour taste.

Kursk. An early ripening, high-yielding variety with oval fruits weighing up to 140 g with thin skin. Tolerates shade and low temperatures well.

Lemon 008. Russian high-yielding variety up to 1.5 m high with round fruits. The peel is medium thick, slightly wrinkled, yellow in color. The pulp is very juicy and sour.

The variety is remontant - it blooms and bears fruit at the same time all year round.

Maikopsky. A high-yielding variety with oval oblong fruits weighing up to 150 g. The peel is medium thick, glossy, ribbed. The variety is early-bearing – it blooms in 2–3 years.

World. A high-yielding domestic variety with beautiful round fruits weighing up to 400 g, bright yellow, with thin skin. The pulp is juicy, with a strong special aroma. A distinctive feature of the variety is that the fruits can be collected in clusters of several pieces.

Novogruzinsky (Novoafonsky). A productive variety up to 2 m high with a spreading crown, round or elliptical fruits with thin yellow skin, juicy sweet-sour pulp. A characteristic feature is quite a lot of thorns.

Tashkent. Uzbek early-fruiting and early-ripening variety with small (up to 85 g) fruits, with thin orange peel. It is distinguished by small leaves and flowers, blooming twice during the year.

Anniversary. Uzbek early ripening variety with round fruits and dense yellow skin. It has a high degree of shade tolerance.

In general, lemon does not have any incredible care requirements, but there are nuances that must be taken into account.

How to graft a lemon tree

Lemon from the seed begins to bear fruit 6-7 years after planting. To speed up this process and grow a tree of your favorite variety, you can use the grafting method.

If you graft a lemon correctly, it will begin to bear fruit within 2-3 years.

To complete the process, it is necessary to grow a seedling, give it time to grow stronger and develop roots. The second stage is to prepare high-quality maternal material. This may be a cutting of an adult lemon variety intended for home cultivation. You will also need some material: pruning shears or a sharp knife, tape, garden varnish, and a damp cloth.

The best period for vaccinations is April-August.

Budding method:

  • Hands and instruments are disinfected.
  • At a trunk height of 5 cm, a T-shaped cut is made on the bark - horizontal 1 cm and vertical 2.5 cm.
  • The grafting branch is cut at an angle (a thin plate with bark should remain).
  • A cutting is inserted into the cut - it should adhere tightly to the tree.
  • The grafting area is wrapped with adhesive tape.

You can graft two kidneys at the same time.


Grafting by budding method

Cleft grafting method:

  • The tree is cut at a level of 5 cm.
  • The grafting material is selected - it must match the size of the trunk.
  • An oblique cut of the scion (in the shape of a blade) and a horizontal cut 2-3 cm deep on the trunk are made.
  • The branch is inserted into the cut, the grafting site is wrapped with tape and treated with garden varnish.

All leaves are removed from the grafted plant, the lemon is covered with a glass jar or bottle. If the scion turns black after a few days, the grafting was unsuccessful.


Grafting into cleft

In the process of growing a lemon tree, it must be fed with fertilizers for citrus fruits, rich in the microelements of zinc and boron. Pruning has a good effect on quality fruiting. First, the central shoot is cut off at a height of 20 cm. Branches of the second and third order need to be pinched when they grow 18 cm; flower buds form on shoots of the fourth order.


Lemon trimming

Growing a lemon tree at home in order to obtain its fruits is a painstaking, lengthy process that requires a lot of effort and patience. It is necessary to ensure the correct temperature, humidity and lighting levels. Propagating lemons from seeds is the most affordable option for beginning gardeners. Having carried out a high-quality grafting, you can expect a harvest already 2-3 years after planting the tree.

Caring for indoor lemon at home

In general, lemon does not have any incredible care requirements, but there are nuances that must be taken into account.

Priming

Lemons are fairly large and fast-growing plants, so they need nutrient-rich soil to grow in a small container. It should be loose, water- and breathable. Ideal soil is loamy with a neutral reaction (pH 6.5 – 7.0)

Most often, a special soil for citrus fruits from a reliable manufacturer is used.

You can prepare soil for lemon yourself. One of the recipes is this: take equal proportions of turf and leaf soil, rotted horse manure, peat and washed river sand. For specimens older than 5 years, the share of turf soil is doubled. Be sure to pickle the mixture and check the acidity level (2).

Lighting

To successfully grow lemons, it is important to provide the plant with good lighting. The best option is a window sill in the southeast direction. Despite its love of light, lemons must be shaded from direct sunlight in summer. By the appearance of a tree it is easy to determine when it does not have enough light: new leaves are small, pale, shoots are weak, and there are few flowers. In this case, it is necessary to either move the plant to a brighter place, or turn on additional illumination with phytolamps, especially in winter.

When kept in cool conditions in the spring, the lemon wakes up early and begins to grow actively. At this time, it is necessary to increase the illumination, and when it gets warmer, move the lemon to the balcony or garden. In the garden, the lemon tree is placed under the light, diffused shade of trees.

Temperature

Lemon is a subtropical crop, so the comfortable temperature for it is 14 – 16 °C. But it easily tolerates both lower temperatures in winter and summer heat. However, it is important for him that the difference between day and night temperatures is no more than 6 °C. Especially during the flowering period.

In indoor conditions, some varieties of lemon also bloom in winter, so on a cold windowsill you need to place a piece of polystyrene foam or thick cork under the pot and separate it from the cold glass with film. But the plant also needs to be protected from the heat of the battery, for example, by hanging a damp cloth on it - this will also increase the air humidity.

Lemon loves fresh air, but not drafts. Therefore, regular ventilation must be carried out carefully so that the plant is not exposed to jets of cold air.

Humidity

Humidity plays a vital role in successfully growing lemons. If in the warm season lemons are often taken out into the garden or onto the balcony and there are minimal problems with air humidity, then during the heating season dry air causes great harm to the plant.

The optimal air humidity for lemon is 60 – 80%. If it is lower in summer and the temperature is high, then it is recommended to spray the plants with clean, soft water at least once a day. In winter, the humidity in a living room is always low and the temperature is above 20 ° C, so it is recommended to use air humidifiers or spray the plants 2-3 times a day, place the pot in a deep tray with wet expanded clay, and next to the pot there is a wide vessel with water.

It is also important to wash the plant regularly, removing dust and dirt from the leaves.

Water the lemon rarely, after the top layer of soil has dried to a depth of 1.5 - 2 cm), but generously, draining the water from the pan after 3 - 5 minutes. The water should be settled and at room temperature.

For watering, spraying and a full shower, it is recommended to use rain or filtered water at room temperature with the addition of a pinch of citric acid per 3 liters.

Fertilizers

Lemon nutrition should be balanced. Experienced citrus growers prefer to use special complex fertilizers, or fertilizers such as Ideal or Zdraven. Complex fertilizers must contain boron, manganese and zinc.

Practice shows that lemons respond well to fertilizing with infusions of wood ash and vermicompost.

Feeding

At home, lemons rarely have a dormant period, so the plants are fed all year round. From March to October, fertilizing watering is done once a week using Ideal fertilizer. From November to February – once a month.

To stimulate the formation of fruits and prevent shedding of the ovaries, the drug Bud is used.

During the period of growth and ripening of the fruit, the lemon is fed 2 times with an interval of 2–3 months with a solution of wood ash – 1 tbsp. spoon per 1 liter of water.

When transplanting, a root formation stimulator is added to the water for irrigation.

Trimming

As a result of pruning, it is important to obtain a tree with a low trunk and a harmonious fluffy crown. This will allow you to get a good and stable harvest. The process of forming a lemon crown is long and leisurely.

It is better to prune lemons at the end of winter or in the first days of spring - this increases the chances of active fruiting.

Pruning begins in the first year of life: the trunk is shortened to a height of 20–25 cm. However, it is important that there are 4 buds left on it for the growth of side branches.

In the second year of life, the lemon begins to form a crown. Trim the crown and long side branches, cutting off approximately 10 - 20 cm of the shoot. This is done in the second half of February. Pinching of shoots is carried out during the spring, shortening rapidly growing young shoots. But don’t get carried away with pinching, since it is at the tips of the branches that the inflorescences appear.

In addition to formative pruning, lemons also require sanitary pruning. Individual branches may dry out. But there is no need to rush to remove them, because even on a seemingly dry shoot, dormant buds can come to life.

Transplanting a plant

Lemon is a long-living plant. Planted from a tiny seed, after a few years it turns into a small neat tree. And then the years go by, and the lemon is already a fairly large tree with a spreading crown. Therefore, replanting a plant is the most important care procedure. The step-by-step sequence of actions is as follows:

  1. Place the prepared soil in a new pot, the bottom of which already has drainage. Lightly moisten the soil in an old pot and leave for 5 hours.
  2. Carefully remove the plant from the pot, keeping the earthen lump. If the tree is more than 10 years old, its roots are cut by 2 cm; for young trees this is not necessary.
  3. The lemon root system is immersed in a light pink solution of potassium permanganate for 3-5 minutes.
  4. The plant is carefully placed in a new container, the roots are straightened, after which they are carefully sprinkled with earth and compacted. It is important to prevent the lemon from falling, but you should not compact the soil too much - root rot develops in roots deprived of oxygen.

How to grow a lemon tree from a seed at home

After moderate watering, the pot with lemon is transferred to partial shade, where it will spend a week. Then the plant is returned to its original place.

Additional Information! Knowing how lemon grows will allow you to transplant on time. It is recommended to do this every 5 years or if the tree is “uncomfortable” in a tight container.

Propagation of indoor lemon at home

Lemons are propagated by seeds, cuttings and layering. However, the seed method is used only for further grafting, because without it, the seedling will bear its first fruits in 20 years. Lemon can be propagated by layering only if you already have an adult tree.

The most affordable way to propagate lemons at home is by cuttings. The best time for cutting cuttings is from April to July, when flowering has finished and the development of the tree has slowed down. At this time, the most favorable conditions for rooting are warm and light.

Cuttings should be cut and trimmed using a sharp and disinfected instrument.

The shoot from which the cutting is removed should be semi-lignified, green in color and bend easily. For rooting, a cutting with 2 to 4 leaves is enough. The lower cut is made oblique right under the bottom sheet, the top cut is 1 cm above the sheet, the bottom sheet is removed. The remaining leaves are shortened by half to reduce moisture evaporation. The lower cut of the cutting is soaked in a root formation stimulator for 8 - 10 hours.

To root the cuttings, you need a pot with drainage holes. Pour a layer of fine expanded clay, then soil (about 2/3 of the height of the pot), consisting of equal parts of leaf and turf soil with the addition of vermiculite or coarse sand. Then pour sand and vermiculite in 2 layers. Water with settled warm water with the addition of trichodermin.

Cuttings are planted, deepening them by 1.5 - 2 cm. If 2 - 3 cuttings are rooted in one pot, then they should not touch each other with leaves.

The planted cuttings are sprayed with warm water (2–3°C above room temperature), covered with a glass or plastic cap, or placed in a greenhouse. The rooting process takes place in a warm and bright place, but without direct sunlight. The cuttings are regularly watered, ventilated daily and sprayed with water.

In favorable conditions, after 1 month roots will appear and the cutting will begin to develop. After this, gradually, over 10 days, the shelter is removed.

The cuttings are grown in the same pot, adding fertile soil and ensuring regular fertilizing watering. And only the grown cuttings are transplanted into a separate pot with special soil.

Rooted lemon cuttings can bloom in 1 year, but the flowers must be removed.

Landing

Planting a lemon tree at home in a pot is done from seeds. Planting material is taken from purchased fruits. To plant seeds, choose large lemons. For successful cultivation, special soil is selected.

To plant a lemon tree use:

  • purchased soil for citrus fruits;
  • flower mixture;
  • soil with peat;
  • leaf soil;
  • soil with sand and organic fertilizers.

Lemons prefer light, slightly acidic soil with good water permeability. Cultivation begins in a small pot or cup. Indoor lemon also requires drainage.


Lemon needs good lighting

Landing sequence

  • Place drainage at the bottom of the pot. Its volume should not exceed 20% of the total size of the pot.
  • Place a layer of substrate on top. It is loosened until fluffy. The soil layer should not be higher than the neck of the pot.
  • Plant the seeds. They are placed at a depth of 1.5-2 cm. The seeds are planted immediately after extraction from the fruit.
  • Place the pot in a bright room. The suitable temperature for seeds is 19°C-21°C.

It is better to plant 10-15 seeds at a time. This will allow you to select the strongest shoots for replanting. Pot shards, nutshells or small pebbles are suitable for drainage. Also, before planting, seeds are treated with biostimulants.

Seedling care

For indoor lemons, maintaining a constant temperature is important. For better germination, the lemon tree sprout is covered with cling film or half a plastic bottle. The first shoots appear after 2-4 weeks. The seedlings are kept under cover until 3 leaves appear. From one seed 1-2 shoots grow.

The plant is moved to its usual place. The soil in the containers is regularly loosened to provide access to moisture and oxygen.

Replanting indoor lemons at home

Lemon transplantation is carried out for the first time after you have purchased a seedling. Then it is done annually at the end of February until the age of 5, and then only when the root system outgrows the pot (the roots penetrate the drainage holes). But every year you need to remove the top layer of soil and add fresh soil.

To replant, remove the lemon from the pot, lightly shake off the soil, cut off the damaged roots, and sprinkle the cuts with charcoal.

One-year-olds are planted in pots with a diameter of 10–15 cm, two-year-olds in pots with a diameter of 15–20 cm. Then, with each transplant, the diameter of the pot should be 4–5 cm larger than the old one. For an adult fruit-bearing lemon, a pot with a diameter of about 50 cm is sufficient.

The lemon pot should have a classic cone shape, smooth inner walls, with a diameter equal to or slightly less than the height, and good drainage holes. First, pour a 2 cm layer of drainage material into the pot, then 2 cm of river sand and 6–7 cm of prepared soil.

The seedling is lowered into the pot and, slightly compacted, fresh soil is added. Then water, excess water is drained from the pan.

When transplanting, it is important not to bury not only the grafting site, but also the root collar.

To prevent diseases, add 2-3 tablets of Glyocladin to the soil.

Hybrid species of lemon trees for home cultivation

Since lemon is a natural hybrid, the tree does not have separate species. Based on the alpha hybrid, breeders have developed varieties for growing ornamental lemon trees. These hybrids do not differ in the shape of foliage or root system and do not require an individual approach to care. The shade of the flowers, the skin of the fruit, as well as its size and yield may differ.

Lemon Novogruzinsky

Grows up to two meters. Lush crown with thorns on the branches. In a year it can bear up to two hundred small fruits.

Lemon Pavlovsky

It also does not exceed two meters in height. The crown is not very lush. The annual harvest is up to 50 fruits. However, lemons are very large, 100-150 grams. The peel of the fruit is very thin.

Lemon Lisbon

A standard two-meter tree with thorns on its branches. Produces approximately 40-60 thick-skinned, large fruits per year.

Meyer lemon

A miniature tree about a meter high. Lush crown and thorns on the branches. Lemons have orange peel, are large and heavy. Productivity is up to 50 fruits per year.

Lemon Jubilee

Trees grow up to half a meter. It differs in the size of the fruit. Some specimens weigh half a kilogram.

Lemon Genoa

A low tree within a meter. Very dense crown. There are no thorns. The peel of the fruit has a greenish tint, but the taste is not characteristic of lemon - the pulp is saturated with sugars. It produces several hundred fruits per year.

Diseases of indoor lemon

The lemon tree is most often affected by late blight, horse rot and scab. However, in recent years, viral diseases have also become common.

Late blight. It causes flowers to fall off, dark spots on leaves and twigs to dry out.

When signs of the disease appear, it is necessary to remove the affected shoots and spray the plant and soil in the pot with Bordeaux mixture (3).

Scab. The scab pathogen causes round spots to appear on leaves, shoots and fruits, which turn brown over time.

When a disease is detected, the first step is to remove the damaged parts, and then treat the plants with Bordeaux mixture or Strobi.

Root rot. It causes shedding of ovaries, leaves and drying out of branches.

First of all, it is necessary to inspect the root system, remove the affected parts, sprinkle the cuts with crushed coal and transplant the plant into new soil. And dig Glyokladin tablets to a depth of 1 - 2 cm.

Viral mosaic. Manifests itself in the form of yellow spots and curling of leaves. The disease causes growth retardation and plant depression.

It is impossible to cure the plant - the affected lemon is destroyed. For prevention, it is necessary to follow agricultural practices and promptly destroy pests.

Tristeza. This disease corrodes woody shoots, causing leaves to turn yellow and branches to dry out. The virus is spread by aphids.

The plant cannot be treated - the plant must be burned.

Gum treatment. A physiological disease provoked by sharp temperature fluctuations, excess nitrogen in the soil and lack of microelements.

Treatment consists of cleaning and treating damaged areas with a solution of potassium permanganate, replacing the soil, balanced nutrition, and watering with warm water.

Reproduction

Indoor lemons are propagated by cuttings and grafting. For cuttings, choose shoots 4-5 mm thick and at least 12 cm long. The lower cut is made under the bud, and the upper one above it. Each cutting should have 2-4 leaves and 3-5 buds.

The segments are treated with biostimulants for root growth and lowered with the lower cut into warm water. After 2-3 days, they are planted in glasses to a depth of 3 cm. For cultivation, a flower mixture with organic fertilizers and river sand is used.

Cuttings do not have a root system, so spraying is used to moisten the plants. They are processed 2-3 times daily. For spraying, use settled water at a warm temperature. The suitable temperature for cuttings is 22°C-24°C.

Roots appear in 4-6 weeks. After their appearance, the plants are transplanted into separate pots.

A rootstock is taken for grafting. It is a young seedling, the thickness of its branches is at least 1 cm. It is also used on orange bushes. An ungrafted lemon develops worse.

Pests of indoor lemon

Mealybug. The appearance of a mealybug can be noticed by a “snowy” coating on the leaves and sticky drops.

If no action is taken, the plant will slow down and even stop growing. The simplest method of prevention is moist air and regular wiping of the leaves with a damp cloth. However, if the infestation is severe, pesticides must be applied. In indoor conditions, it is better to limit yourself to Bitoxibacillin or Fitoverm. In warm weather, you can take the plant out into the open air and use Aktara or Bankol (3).

Shield. It affects the trunk, branches and leaves; its colonies look like dirty drops, sticky to the touch. The activity of scale insects leads to yellowing and shedding of leaves, flowers and ovaries, and oppression of the plant.

At the beginning of infection, washing the plant with a sponge and soapy water has a good effect. Remove pests from the trunk and branches with a cotton pad soaked in alcohol, then wash with water. Scale insects can be completely destroyed by using Actellik or Fitoverm (3).

Spider mite. Damages leaves, which as a result curl into tubes and fall off. It reproduces most aggressively in a dry atmosphere.

To destroy spider mites, use increased air humidity, daily spraying with clean water and treatment with sulfur preparations - colloidal sulfur or Tiovit jet (3).

Rules for growing lemon fruits

The development and ripening of fruits on a lemon tree takes from 7 to 9 months. During this period, several rules must be observed:

  • avoid temperature changes;
  • do not turn or move the flower pot again;
  • Do not trim stems or leaves.

The foliage of the tree plays a very important role in the ripening of lemons. It is she who provides them with carbon dioxide and nutrients. It is believed that at this time at least ten leaves should grow on the plant for each fruit.

Ripe lemons are picked one and a half to two months after formation. If not harvested on time, the skin will become thick and rough, and the flesh will become dry.

Popular questions and answers

We asked agronomist Oleg Ispolatov - he answered the most popular questions from gardeners.

How to choose indoor lemon?

When buying a lemon, pay attention to its appearance: the leaves should be shiny and rich green. No signs of pests or diseases. Be sure to inspect the leaves from the underside. The root system is developed, but it is undesirable for the roots to grow through the drainage holes.

What kind of pot is needed for indoor lemon?

The pot for each transplant should be 2–3 cm larger in diameter than the old one. This rule is. The height of the pot should be 2 times less than the diameter of the top part. Lemons need to be replanted regularly, so the shape of the pot should be classic, strict, without any protrusions or decorations.

Why does indoor lemon turn yellow?

Most often, yellowed lemon leaves indicate that there is not enough iron in the diet. Therefore, feed the fertilizer with iron or spray it with Ferovit.

Why do indoor lemon leaves fall off?

Dropping leaves indicates stress in the plant. And it can be caused by a sudden change in location, lighting, or errors in watering and fertilizing.

Why do indoor lemon leaves curl?

Curling of lemon leaves clearly indicates a lack of macro- and microelements: - copper - the leaves darken and begin to curl from the tip of the leaf;
– magnesium – leaves turn pale and curl; – potassium and boron – leaves turn pale and curl. Adding these batteries will pause the process.

Why do the fruits of indoor lemons fall off?

There may be several reasons.
The first flowering is often weak and barren. But even during abundant flowering, some of the fruits will definitely fall off - this is how the plant signals that it is not ready for a big harvest. But it often happens that the shedding of the ovaries is caused by insufficient light and nutrition. Pests can also weaken the plant. Sources

Pests and diseases

If lemons do not bear fruit, this is a sign of infection. Symptoms include yellowing of foliage and wilting. Although the lemon tree is a plant that has good pest resistance, it is susceptible to fungal diseases.

Causes of yellow leaves:

  • dry air;
  • lack of nutrition;
  • staying near heating appliances in winter;
  • pest infestation.

The disease leads to drying out and loss of foliage. To prevent illness, lemons are regularly sprayed and watered. Fertilizers are also applied at the required time. If a tree is crying, there is an excess of moisture in the soil.

Types of indoor lemon pests:

  • spider mite;
  • aphid;
  • whitefly;
  • scale insect;
  • white mosquitoes;
  • mealybug.

To combat them use:

  • "Aktellik";
  • "Akarin";
  • "Fitoverm";
  • "Kleschevit."

If pests appear, lemons are treated with onion peels or garlic infusion is used. Take 200 g of product per 1 liter of water and infuse for a week. Wiping the leaves helps against aphids.

The indoor plant is exposed to fungal diseases of the branches and roots. The reason for their appearance is excess moisture in the soil. For treatment, the affected segments are removed, the wounds are treated with growth stimulants and the tree is transplanted into new soil.

Preparing soil for lemon seeds

Before you start planting seeds in the ground, you need to prepare the pots and soil. For active germination of grains, both special soil for citrus plants, sold in flower shops, and homemade soil are ideal. If purchased soil is already ready for use, then homemade soil needs to be given a little time and attention. It should consist of:

  • ½ turf land;
  • ½ humus soil;
  • a small amount of fertilizer - charcoal and/or peat.

Advice.
Flowerpots for planting must be spacious and deep so that the root system has room for its growth and development. Planting a grain in the ground:

  1. Expanded clay, pieces of charcoal or foam plastic are placed at the bottom of the flowerpot (this material will serve as drainage).
  2. The pot is filled with prepared or purchased soil.
  3. The earth is moistened with rain or purified water.
  4. Several grains are planted in a container and immersed to a depth of 0.5-1 cm.
  5. The flowerpot is covered with film to create greenhouse conditions.


With proper planting, sprouts appear quite quickly.
After 2-2.5 weeks, the first sprouts will appear on the surface of the soil, the strongest of them are transplanted into another container for further germination.

How to feed lemon?

Lemon can bloom and bear fruit in the 2-3rd year. Caring for indoor lemon is:

  • timely watering;
  • regular spraying;
  • competent feeding.

Once a month, after watering, add a dose of nitrogen fertilizer dissolved in water (urea or ammonium nitrate - 2 g per 1 liter of water) into the soil. This is especially true for soil poor in organic matter. Nitrogen gives strength to plants; during spring and summer, a powerful leaf apparatus is formed, with which the tree safely endures all the hardships of winter. You can water with diluted slurry of low concentration (1:30).

Under no circumstances should you fertilize with microelements. Unlike other plants, lemons do not have hairs on their roots. Their role is played by mycorrhizal fungi. They seem to stick to the roots of the lemon, and through them the whole plant is fed. Mycorrhizae themselves feed on organic matter, for example, humus. They decompose it, forming valuable substances, which they first feed on themselves, and then feed the lemon. Trace elements kill mycorrhiza, thus the tree is depleted and will soon die. Excessive nitrogen feeding is not good for lemons. The tree can grow with a powerful crown to the detriment of fruiting.
