How to grow a tangerine tree from seed

How to Germinate Tangerine Seeds | Home Guides

By SF Gate Contributor Updated September 10, 2020

Tangerines (Citrus reticulata) are citrus fruit similar to small, sweet, loose-skinned oranges. Originally from Southeast Asia and southern China, a tangerine tree can be grown in California and other areas of the United States, in U.S. Department of Agriculture plant hardiness zones 8b through 11, notes Floridata.

By growing tangerines, you can save money, add ornamental value to your home or garden, and stop worrying about chemicals used on the fruit you eat. While tangerine trees are usually started by grafting, growing a tangerine tree from seed is a satisfying long-term project.

  1. 1. Disinfect Tangerine Seeds

    Fill the sink with water and add 1 teaspoon of bleach. Wash the tangerine seeds in the liquid to disinfect them. Rinse them off with water. Skip this step if you purchased your seeds and didn't extract them directly from the fruit.

  2. 2. Begin Seed Germination

    Soak the seeds in water for eight hours to help promote the germination process.

  3. 3. Prepare Seed Pots

    Sanitize the pot or flats you will be using by soaking them in diluted bleach for 15 minutes, advises Fine Gardening. Once dry, fill a 3-inch diameter pot with moist potting mix up to approximately 1 inch from the top. Tamp the soil with your fingers so it's firm in the container. As an alternative, use a seed-raising flat or peat pellets.

  4. 4. Growing Tangerines in Pots

    Place up to three seeds on the soil surface, spaced an equal distance apart. Cover them with a 1/2-inch layer of soil. Lightly press down on the soil to firm it over the seeds.

  5. 5. Moisten Tangerine Seeds

    Fill a spray bottle with water and use it to moisten the top layer of soil. Pouring water onto the soil may work as well, but be careful not to wash away the seeds or get the soil too wet which may cause a fungal infection, notes Fine Gardening.

  6. 6. Cover Seed Pots

    Stretch a piece of clear plastic wrap over the pot to insulate the seeds. Secure the plastic with an elastic band. This helps to keep the soil moist.

  7. 7. Maintain Warm Temperatures

    Place the pot in a warm room so the seeds can germinate. Check the soil regularly and spray with water as needed to keep it moist at all times. Aim for a temperature between 65 and 75 degrees Fahrenheit. Avoid drafty windows and place a heating pad under the pot or position it near a heater, if needed.

  8. 8. Expose Seedlings to the Sun

    Relocate the pot once the seeds germinate. Expect the seeds to germinate over a period of two weeks. Remove the plastic wrap and place the pot in a location where it's exposed to sunlight.

  9. 9. Transplant Tangerine Seedlings

    When they are 4 inches tall, transplant the tangerine seedlings to larger pots. If you live in a warmer climate, you can also transplant directly into the garden, after the last frost in your area. Tangerine trees grown from seed may not bear fruit for 10 years. Fruit on seed-grown trees may not be the same as the fruit from which the seed was taken.

How deep should tangerines be planted?

The depth of the hardy types should be around ¾ inch for planting, with grapefruit varieties requiring a bit more space.

The common citrus trees (oranges and tangerines) are classified as "hardy" or "sensitive".

Hardier oranges can grow in soil that is slightly colder than sensitive ones.

The hardier citrus should be planted at least six inches deep, and the sensitive types need to be buried about three feet.

The kind of soil a tree grows in will affect this as well, with clay pots or heavy soils requiring deeper planting depths than lighter ones.

Where do you grow tangerines?

Tangerines are an uncommon fruit and can be expensive to purchase.

Growing tangerine trees from seeds is a rewarding project with plenty of benefits for the gardener.

Tangerines thrive in coastal areas, though they will grow well on other types of soil as well.

The plants require full sun exposure or at least six hours each day.

Tangerines are a member of the mandarin family and have similar needs.

Tangerine seeds should be planted in the soil during late winter or early spring, so they can grow plenty of roots before summertime when citrus plants require lots of water to thrive.

The seedlings will need at least one inch of water each week to stay healthy.

Tangerines need plenty of fertilizer throughout the growing season, including high nitrogen and potassium levels for vigorous growth.

When do you grow tangerines?

Tangerines grow in the winter months, specifically December through March.

These are cold-hardy citrus trees because they can withstand temperatures as low as 20 °F (-12 °C).

They require a frost to bloom and fruit well.

Most citrus trees must be grown in containers because they can't tolerate cold.

The tangerine is an exception; it will grow and produce fruit, even when planted outside during the winter months.

This makes gardening with these plants a lot easier than other types of indoor or outdoor planting.

How do you propagate tangerines from seeds?

You will need to gather seeds from an adult tangerine tree.

If you are unsure of the quality or type, use a few more than required if some do not germinate.

The fruit should be fully ripe and feel heavier than its size would suggest, with a gelatinous seed mass inside when squeezed gently.

Take care due to the rough skin on the fruit and avoid any that are bruised or damaged.

Once you have your seeds, soak them in water for about 24 hours to help loosen the tough outer layer before planting them.

The seed coats should peel off easily after soaking, but it can be tricky, so use a little soap if needed.

You will also need to cut off any excess pulp, peel, and pith before planting.

The seed should then be placed about ½ inch into the soil/compost mix with approximately ¼ to ½ of it exposed above ground level.

If you are growing your tangerines outside in a pot or container, make sure that they have plenty of space for the vine to grow and that the pot has good drainage.

If you are planting them in a garden bed, be sure to give plenty of space for root growth with well-drained soil/compost mix or use an underlayment if necessary (such as aerated clay pebbles).

If growing your tangerines indoors, make sure they have enough light, and don't forget to water them regularly.

The tangerine seedling will emerge from the ground in about one month with a robust root system and no signs of soil on its roots or trunk.

It should also have all five true leaves visible at this stage: thick, glossy green leaflets that grow opposite each other.

How much light does tangerines need?

Tangerines need a lot of light to grow.

They prefer full sunlight, so be sure not to plant them under other trees or plants that will block the sun from reaching their leaves and fruit.

The best time for planting tangerine seeds is during the fall, when days are shorter but still long enough for good sunlight exposure.

How do you water tangerines?

Wet tangerines soil every other day.

They need a deep watering about once per week.

If you use an overhead sprinkler, make sure that the roots are not soggy and in danger of rotting to death because the ground is too saturated with moisture.

This can happen if you have been raining a lot or living near bodies of water where the soil is saturated.

How do you fertilize tangerines?

Tangerines, like most citrus plants, need a lot of potassium.

Typically they are fertilized with nitrogen and phosphorus as well.

The best time to fertilize is when the plant has finished blooming.

When you see new growth coming in after rain or irrigation, it's the perfect time for fertilizer application.

You can also add fertilizer to the soil before planting.

Mulch should be added in late winter or when new growth starts in the spring and fall seasons.

This is done for several reasons, but primarily it will keep moisture levels down, which can help protect against fungal diseases that overwinter on living leaves like scabs and preserve water for the plant's root system.

How do you get rid of pests and diseases on tangerines?

Several pests and diseases can attack tangerine trees.

The most common pest is the citrus red mite; this tiny parasite attaches itself to leaves and sucks out the sap, which causes them to turn brown.

To get rid of these critters, you should use commercially available products or another method such as spraying with soapy water or using citrus oil.

Diseases are also common on tangerine trees, but they're less likely than pests to kill the tree.

Some of these diseases include leaf chlorosis (yellowing), sudden decline (symptoms: wilting and yellow leaves), and root rot (symptoms: brown roots).

If you detect one of these diseases, you should remove the affected tree and replace it with a new sapling.

How do you harvest tangerines?

The best way to tell if a fruit is ripe enough for harvesting is by checking the color.

Mature, sun-kissed oranges should be bright and vibrant in hue with no signs of green or brown on their skin.

If they have some discoloration, it's likely due to the time of year or a light rainstorm.

When you're ready to harvest, gently pull on an orange and feel it give way with slight pressure.

You can also use your thumbnail against the skin as another test for ripeness.

If there is resistance when you press into the fruit, it may not be ready for harvesting.

If the fruit is ripe, it will come away from the tree quickly, and you may have to shake or jiggle them free of its stems.

Be sure not to break off any part of a stem when removing tangerines.

This can be hard if they've had one long season on the branch, but it's much easier if the fruit has been on a tree for many years.

When you pick tangerines, make sure they are free of any pests or diseases that may have made them unfit to eat before removing their stems with your fingers.

You can also use scissors or pruning shears as an alternative.

How long does it take to grow tangerines from seeds?

Growing tangerines from seeds can take anywhere from two to four years.

It just depends on the variety of tangerine and how well you grow them.


Tangerine trees can be grown successfully indoors and outdoors so long as they're given plenty of sun exposure each day.

Whatever your preference may be for how you want to grow tangerines, we've provided some tips on getting started below.

Let us know if you have any questions about these methods, and let us help you begin growing delicious citrus fruit at home today.

How to grow a tangerine from a stone?

At home, you can grow not only traditional plants, but also exotic crops. A tangerine can become an interior decoration, which, knowing the rules, can be grown on your own.

Have you ever grown tangerines from seed? If not, or if you tried, but nothing worked, read our article on how you can grow mandarin at home. Is it possible to grow a tangerine from a seed?

Growing mandarin from the stone is a long process that will not bear fruit soon. But, if you take an adult citrus plant in a store, then it is likely that when the living conditions change, it will die. And the cost of such a tree is not affordable for everyone. Indoor mandarin seedlings are very rare, so it remains to grow a tree from seeds on your own.

The experience of amateur citrus growers confirms that at home it is really possible to grow a plant from a stone that will bloom and bear fruit. To do this, you need to try and create conditions close to natural.

Important! Indoor mandarin grows up to 1.5 m and usually blooms at 6-8 years of age, but this period can be significantly reduced by grafting and proper pruning.

The fruits are set by self-pollination and stay on the branches for several months.

Growing mandarin from stone

And now more about how to grow mandarin from stone at home conditions.

The most suitable time for planting seeds is the autumn-winter period, when the fruits naturally ripen in nature. From the eaten tangerines, choose a dozen thick, rounded seeds. Bones have good germination, but to be sure, it is better to plant more of them.

Seeds that are still damp are planted immediately in the ground. If they had time to dry before planting, they are placed in wet gauze for a couple of days to improve their germination. After pecking, the sprout is planted in pre-prepared cups.

Mandarin soil

Before planting mandarin seed it is important to know that the plant does not tolerate acidic and alkaline soils. Heavy clay and too light peat mixture will not work either. The best option for citrus fruits would be nutritious, loose, permeable soil with a slightly acidic and neutral reaction.

You can take a ready-made mixture for citrus fruits or prepare the soil yourself from soddy, leafy soil and manure, preferably horse, humus in equal parts. Here also add coarse river sand in the amount of 10% of the total mass.

Sift the mixture thoroughly. Heat treatment is carried out: 10 liters of substrate in an iron bucket are poured into 1 liter of water, covered with a lid and boiled for half an hour. After cooling, you can start planting.

Mandarin pot

Ordinary plastic cups with a volume of 100-200 ml or small pots about 10 cm high are suitable for planting seeds. did not stagnate. After the seedlings grow up and the root system fills the entire earthen ball, they are transplanted into containers a couple of centimeters larger than the previous ones.

How to grow indoor tangerines from the stone step by step, read in the next paragraph.

How to plant a tangerine stone - step by step expanded clay.

  • Pour prepared soil, moisten.
  • One seed is planted in each glass to a depth of 1-2 cm.
  • To maintain moisture and rapid germination, cover hermetically with foil.
  • Containers are placed on a bright windowsill with a temperature of 20-25ºC.
  • After 2-3 weeks, seedlings indoor mandarin will appear and the film will need to be opened little by little so that the shoots gradually become accustomed to fresh air.

    Care for homemade tangerines

    Basic care for tangerines from the stone is as follows:

    • moderate watering with barely warm settled water, without overdrying and overmoistening of the soil;
    • daily spraying;
    • citrus fertilizer according to instructions during the growing season.

    Important! It is possible to successfully grow tangerines, but the main difficulty lies in creating the right wintering conditions.

    In cold weather, plants can be kept both in a warm and in a cold room, but care, depending on the chosen method, will differ significantly.

    On a cold balcony or in an unheated room, it is important to maintain positive temperatures throughout the day, but not to exceed +5°C. If the room is dark, you will have to turn on artificial lighting for 12-14 hours. It is necessary to ventilate the room daily and make sure that the tree is not in a draft. To avoid freezing of the roots under the pot, be sure to put a piece of foam.

    Water the plant very rarely and little by little. They don't fertilize. In the spring, when the frosts pass, the plant is taken out into the street. Gradually resume watering and top dressing.

    Important! To avoid burning the leaves, the flowerpot is placed in the shade for a couple of weeks, only then it is gradually moved to the sun.

    If the tangerine is in a warm room in winter, it is very important to maintain daylight hours for him, using additional lighting. In warm conditions, the plant does not go dormant and continues to grow, so watering and fertilizing continue, but the dosage should be halved.

    To maintain air humidity, the crown is sprayed with water several times a day. If the tree pot is on a cold windowsill, place an insulating substrate under it. Ventilate the room often, avoiding drafts. In the spring, when the air temperature outside is the same as indoors, take the tree outside, gradually accustoming it to the air.

    How to graft a tangerine from the stone?

    In order for the tangerine tree from the stone to start flowering earlier, it is grafted at 2-4 years of age. You can vaccinate in different ways, for example, using budding. To do this, you need a kidney of a fruit-bearing tree. If there is nowhere to get it, try to find tangerines with twigs in the store. The main thing is that the branch is not dried and not frozen. Collect a few branches, renew the cuts, wrap them in a damp cloth and place them on the bottom shelf of the refrigerator for a week. If after this time the cuttings have not deteriorated, they can be taken for grafting.

    Grafted indoor mandarin seedlings usually begin to bear fruit at 4-5 years of age.

    Mandarin top dressing

    During the entire growing season, the plant needs frequent top dressing. Seedlings in the first year do not fertilize, they have enough useful substances that are contained in the soil. In the second year of life, they are fed with special formulations for citrus fruits or diluted manure infusion.

    When stone tangerine bears fruit , it is fed with special fertilizers according to the stage of development. In the spring, nitrogen preparations are used to build up the leaf mass, during flowering and fruiting - compositions where calcium and phosphorus predominate. By winter, top dressing is gradually stopped.

    Mandarin formation

    In order to grow a mandarin at home from the stone into a lush tree with a rounded crown, a forming pinch is made for it. It is important to know that the fruiting of a citrus tree is possible only on branches of the 4th-5th order. When the seedling grows up to 30 cm, they begin to pinch it, removing the ends on all shoots after 4-5 leaves.

    Important! Indoor mandarin also needs sanitary pruning: weak, dry and growing shoots are periodically removed.

    Transplantation of mandarin seedlings

    Young indoor mandarin seedlings are transplanted every year as the roots of the earthen coma in the pot are mastered. Adult, fruiting trees - once every few years. If the plant is large, then once again it should not be disturbed. You just need to replace the top layer of soil in the pot with a new one.

    Transplanting is best done in spring. The plant is watered so that the clod of earth is well behind the walls of the pot, and transferred to a new, 5 cm larger flowerpot with arranged drainage. Make sure that the trunk is in the center of the pot, and the root collar is at the same level with the ground. Water and, if the soil has settled, add a little earth.

    Most of our children, and often we ourselves, adults, began our acquaintance with botany with a tangerine. Orange, fragrant, with bright slices and inconspicuous seeds, it led us to the question: is it possible to grow such a miracle on our own? And if this question overtook us not far from the pot of earth, even if it was already occupied by some kind of plant, the seeds immediately went into the soil. And after a while, the already forgotten experiment turned into a difficult task: how to care for and get fruits from your own tangerine in home-grown conditions? In the article we will talk about this.

    Mandarin from the stone - analyzing the difficulties

    Before deciding to grow a mandarin from the stone, you need to think: how much are you ready to work to achieve the result, and what exactly do you want from the tree you grow - just decorative or also fruits? Are you ready to wait? Mandarin from the stone grows quite slowly. Are you willing to experiment? In order for the plant to bloom, it will take more than one year, and it is not uncommon for a tangerine to not bloom at all, then you will need to help it.

    In addition, if a tangerine grown from a stone produces fruits, they are not similar to those from which the seed was taken (in order for the variety to repeat, it is necessary to propagate it vegetatively - by cuttings, grafting). However, what happens, in any case, pleasantly surprises!

    Planting mandarin

    What seeds to plant?

    For planting tangerines, it is best to take seeds from the numerous hybrids offered for sale today. They sprout faster, bloom earlier, in most cases produce edible fruits and are easier to graft. It is very simple to distinguish them from real tangerines: real ones do not have seeds in their fruits, or there are very few of them, and hybrids are always with seeds.

    Selected seeds should not be thin, as if withered, deformed or with a blackened tip. It is good that there are at least five tangerine seeds, since not all will germinate, and if the plants are planned for grafting, then at least ten, because grafting is not always successful.

    Preparing the soil and choosing a pot

    The next task is to prepare the substrate. It should not contain peat, as the mandarin does not like acidic soil. Therefore, the substrate is either bought in a store, marked pH = 6.5-7 (neutral soil), or made independently by mixing two parts of well-rotted humus, two parts of forest land (from under deciduous trees) and one part of sifted river sand. If there is no humus, you can just take non-acidic soil and sand.

    Now you need to choose a container for planting. The first pots for young tangerines are quite capable of becoming plastic cups with a volume of 200 ml, bowls, at least 7-9 cm deep (always with a drainage hole) or small pots.

    Planting mandarin seeds

    There is a common rule for all citrus fruits: the faster the seed from the fruit gets into the soil, the higher its germination. Therefore, after eating a tangerine, you do not need to dry its bones, you must immediately place them in the ground, digging them to a depth of 4 cm.

    If, for some reason, tangerine seeds could not be planted immediately, then, in order to slightly speed up the germination process, it is recommended to soak them for several days. At the same time, the dishes in which they will lie should be flat, the cloth should be damp, but not flooded with water, the place should be warm, but not in the sun. So that the rag in which the tangerine bones are wrapped does not dry out, the saucer can be placed in a plastic bag, slightly cover it, but do not tie it.

    From seed to seedling

    There is no way to tell how long it will take for a seed to germinate and sprout. In some cases, it is 15 days, but more often - about a month. In any case, before germination, it is important to monitor soil moisture and air temperature, which should not fall below +20 ° C and exceed +25 ° C. At the same time, it is not recommended to place pots in a mini greenhouse, tangerines sprout so well, and plants grown in greenhouse conditions will then need to be accustomed to room conditions.

    Transplanting mandarin seedlings

    If the mandarin seeds are planted not in separate pots, but all together in a bowl, when four leaves appear (it is believed that citrus fruits do not have cotyledon leaves), it is time to transplant them into separate cups. From the resulting seedlings, the most powerful are selected, and the weak and deformed ones are discarded, obtaining plants that are stronger and more capable of growth and development.

    Sometimes it happens that two sprouts grow from one tangerine seed (citrus fruits have multiple seeds). In this case, you can do two things: either pinch a weaker plant, or plant the sprouts in different pots - usually each of them has its own root system.

    The next mandarin transplant should be oriented towards root development: as soon as the roots occupy the entire volume of the cup, the plant is transferred to a larger pot. But immediately planting a seedling in a large amount of land is highly discouraged, because in this case waterlogging of the soil often occurs, which significantly depresses the plant.

    Young mandarin trees are replanted annually. Fruiting - once every 2-3 years, increasing the diameter of the pot not by 1, but by 4-6 cm. When planting, it is important to make sure not to deepen the root collar.

    Old plants and large specimens of tangerine are not replanted, but every few years the top layer of soil in a pot is carefully removed, replacing it with a new, fertile one.

    Mandarin shaping

    Mandarin is one of those plants that often needs to be shaped. The first pinching (if he has not started branching himself) is done when the seedling reaches a height of 30-40 cm. This technique causes the tree to start up side shoots of the first order. But this is not enough for flowering, because mandarin bears fruit only on branches of the 4th-5th order. Therefore, pinching is continued, removing the tips of all shoots after 4-5 leaves, as well as weak shoots and those that grow inside the crown. In general, the formation takes 3-4 years.

    But to force branches of the first order, you can go the other way - to reject the shoots with the help of fixation. This method is more time consuming, but quite interesting. For its implementation, one end of the wire is fixed on a twig, and the other is fixed with a hairpin at the edge of the pot so that the formed mandarin shoot leans closer to a parallel position with respect to the ground.

    Mandarin care at home

    The care of tangerine trees varies somewhat depending on their age and purpose. If the specimen is young (up to 5 years old) or grown solely for the sake of green foliage, it needs regular watering (the soil must be kept moist, but not flooded), spraying (quite frequent) and a lot of light (with shading in the summer from the bright midday sun and illuminated in winter days).

    During the warm months, the tree can be taken out into the air (gradually accustoming) to a place protected from the wind. Once a month, it is useful for a mandarin to arrange a warm shower.

    Like other citrus fruits, mandarin has the ability to turn the leaves towards the main light source. Therefore, for a more uniform formation of the crown, it can be rotated around its axis. But this should be done no more than 10 ° C at a time and no more than once every two weeks, because citrus fruits do not like rearrangements and may react negatively to them.

    If the tangerine has begun to bloom, then, in addition to the usual care, it needs a period of winter dormancy, at a temperature of +10..12 ° C with more rare watering (it is necessary to allow the earth to dry out a little), a gradual increase in temperatures in the spring and optimal temperature conditions for the formation of buds (within +16..18 °C). As well as moderate heat in summer - no higher than +25 ° C (at a higher temperature, the flowers may crumble) and careful spraying (water should not fall on the flowers).

    Since tangerines ripen for about 6 months, many people have a question: should the tree rest in winter or should it be illuminated with a lamp so that the fruits ripen? Answer: arrange. Even at +10..12 °C, tangerines slowly ripen.

    Tangerine feeding

    Small tangerines are not fed, they are simply transferred to a larger pot. But older plants need to start fertilizing from the beginning of spring growth until autumn. This must be done with a special fertilizer for citrus fruits or mullein infusion (1:10 with water) every two weeks. Suitable for top dressing and chicken manure (tincture 1:20 diluted at the rate of 1:20 with water).

    If the tree is planned to be transplanted, mandarin must be fed at least three days before this event. After transshipment, they return to fertilizers no earlier than 2 weeks later. In winter, tangerines do not feed.

    The first fructification of tangerines

    The tangerine, grown from the stone, begins to fructify in the 5th-6th year. Its fruits do not exactly repeat the taste of the mother variety and may differ from it in size, sweetness, aroma, but not only in the direction of deterioration of these qualities (as is commonly believed), but also in the direction of improvement (here - as lucky).

    At the same time, the first fruiting does not yet fully reveal all the characteristics of the plant obtained from the seed. Therefore, if the tangerine has blossomed and set fruits, it needs to provide the most attractive conditions so that the tree can prove itself during repeated fruiting.

    How to make a mandarin blossom?

    It's good if the mandarin blossoms by itself. And if not? In this case, he can be encouraged to do so. It is necessary to take a copper wire and wrap it tightly around the base of the tangerine trunk so that it is pressed into the bark. This will disrupt the sap flow process and make the plant “think” about offspring - bloom. After six months, the wire must be removed, and the wounded place should be treated with garden pitch - it will recover quickly enough.

    However, the method will not work if the mandarin has not formed a crown and has not had a dormant period. Therefore, before starting the experiment, it is necessary to help the tree grow branches of the 4th and 5th order and go through a cold winter.

    Mandarin grafting

    Another way to get fruit from a tangerine seedling is to graft it. To do this, it is necessary to grow a stock (tangerine from a stone) to the thickness of a trunk with a diameter of a simple pencil (about 6 mm) and find a scion - a small segment of a shoot taken from a varietal mandarin, or rather, a kidney (eye) with a leaf petiole.

    At a height of 7 cm from the soil on the rootstock bark, make a very sharp cut, preferably with a special budding knife, in the shape of the letter "T" in such a way that it does not cut through the wood. The length of the cut should be about 2.5 cm, the upper jumper (the cap of the letter “T”) about 1 cm. Insert the cut mandarin bud (with the leaf petiole) into the bent ends of the bark (carefully push them away with a knife) and press the bark back. Treat everything with garden pitch and wrap it tightly with blue electrical tape, leaving the petiole out. Place the grafted plant in the greenhouse from the bag.

    If the mandarin grafting is successful, the bud will take root within three weeks, the petiole of the leaf will turn yellow and easily fall off. If the vaccination is not successful, the petiole will turn black.

    In case of success, the greenhouse is gradually ventilated, gradually increasing the session time. A month after the appearance of a shoot from a new bud, the stem of the mandarin rootstock is cut with a pruner at a height of at least 5 mm from the grafting site, obliquely. The bandage is removed. The cut is treated with garden pitch.

    Mandarin care during flowering/fruiting

    In the phase of flowering and fruiting, mandarin needs more phosphorus and potash fertilizers than nitrogen. Watering should be regular, but not excessive. When the plant blooms, it must continue to be sprayed, but in such a way that water does not fall on the flowers.

    In most cases, mandarin sheds extra flowers and ovaries, self-regulating the load. If this does not happen, he needs to be helped by removing extra flowers and tangerines, leaving one fruit on the plant for every 15-20 leaves.

    If ripening tangerines burst, it means that the plant is watered irregularly, or experiences an excess of nitrogen. In order for the mandarin to lay flower buds, he definitely needs winter rest.

    Mandarin Pests

    It has been observed that mandarins grown from seed are much more resistant to environmental influences and pests than those that can be bought in a store. But, unfortunately, he also has malicious enemies. Most of them are afraid of ultraviolet light and high humidity, so maintaining good plant conditions is also a prevention against them. Who is it? Spider mites, scale insects, mealybugs, and also aphids.

    Measuring only 0.3-0.6 mm, it is virtually invisible to the human eye. But you can calculate it by the presence of small light dots on the underside of the leaves of the plant and the presence of the thinnest cobweb. If a tick is found, the fight against it should be immediate.

    The first thing to start with is to thoroughly wash the plant with warm running water using laundry soap. Then it is necessary to spray the tangerine with Fitoverm, Intavir, Aktelik or other insecticide several times at intervals (7-10 days).


    It is a convex oval-shaped plate with a size of only 4 mm. The main sign of its presence is a sticky syrup-like coating that appears on the leaves of the plant. If the pest is not destroyed, the tree quickly depletes and dries up.

    You can try to cope with the scale insect by treating the tangerine with a soapy solution with the addition of kerosene: for 1 liter of water, 5 g of soap and 10 g of kerosene. Spray up to twice a week.

    But more effective treatments (from 3 to 5 times with an interval of 15 days) with insecticides Aktara, Fitoverm or others, which can always be found on sale. However, after such treatment, the fruits from the tree cannot be eaten and it is necessary to change the top layer of earth in a pot.


    It is quite easy to detect: the pest resembles a white fluffy coating scattered over the plant in the form of small dots, 3 to 6 mm in diameter. You can fight the worm manually, painstakingly collecting individuals, with the help of insecticides - Karbofos, Decis, Intavir or infusion of soap and garlic (2 cloves of garlic per 0.5 l of boiling water insist 4 hours).


    Almost everyone is familiar with this pest: 1 to 3 mm long, light green in color, multiplies rapidly, lives in colonies. The harmfulness of aphids lies in the fact that it sucks juices from young shoots and leaves of mandarin, deforming them and depleting the plant.

    In the fight against it, repeated (with an interval of 5-7 days) washing the plant with a solution of laundry soap, spraying with infusion of garlic (1 head of finely chopped garlic per glass of water, leave for 2 days), infusion of tobacco (40 g per 1 liter of water) ).

    Mandarin growing problems

    Yellowing and leaf drop

    This problem can have different causes. It is important not to rush, carefully analyze the condition of the plant and make the correct diagnosis. In adult tangerines, the leaves may turn yellow and fall off due to their old age. But at the same time, the tree itself looks healthy and develops normally.

    General lightening of the foliage may indicate insufficient plant lighting. In this case, care must be taken to rearrange the tangerine closer to the light, or arrange artificial lighting for it.

    Dropping mandarin leaves can begin due to too dry air (in the absence of regular spraying, especially during the heating season), improper transplantation (when the root neck is deepened, choosing too large a pot), drafts. If one of these reasons is found, they simply need to be eliminated.

    Drying and falling off of the lower leaves of mandarin, despite the fact that the leaf begins to dry from the tip, is associated with regular waterlogging of the soil. This phenomenon occurs either as a result of excessive care, or because the pot is too large in relation to the seedling. In any case, the plant must be transplanted into an appropriate pot with fresh, loose (breathable) soil, after removing rotten roots.

    If yellowing starts from the bottom of the crown and spreads to the top, this indicates a lack of nitrogen. In this case, the mandarin must be fed with nitrogen fertilizers.

    Light yellow color of young mandarin leaves, gradually passing to older leaves, indicates chlorosis (lack of iron).
