Kumquat plants have thornless branches and extremely glossy leaves. They bear dainty white flowers that occur in clusters or individually inside the leaf axils. The plants can reach a height of up to 8 feet and grow 6 feet wide. They bear yellowish-orange fruits that are oval or round in shape. The fruits can be 1″ in diameter and have a sweet, pulpy skin and slightly acidic inner pulp. 

Despite being citrus trees, the flowering season of kumquats arrives much later. Kumquat tree flowers in late spring into early summer. It is an easy-to-care, cold-hardy plant that can tolerate temperatures as low as 18°F (-7°C). 

Kumquat Varieties

Massive harvest of kumquat fruits from a small section of one tree.

Botanically, many of the varieties of kumquats are classified as their own species, rather than a cultivar:

  • Nagami: The most popular variety, also known as oval kumquat.
  • Meiwa: Large round kumquat, a hybrid of ‘Nagami’ and ‘Marumi’.
  • Marumi: Round kumquat, a bit spicier in flavor than ‘Nagami’.
  • Hong Kong: A native version, often growing in hilly or mountain regions of China.

Whichever you choose, kumquat trees produce fruit that is are round, oval-shaped, and bell-shaped. Nagami kumquats, which are the most popular, have oblong, juicy fruits, which can be eaten whole or used to make marmalades. 

All the kumquat trees are self-pollinating, so you only need to grow one tree. The plants require moist soil, so they need ample water to prevent drying of roots. Kumquats can tolerate both frigid and hot temperatures.

Planting a Kumquat Tree

Growing a kumquat tree is very easy. Here’s a breakdown of when, where, and how to plant this attractive evergreen tree. 

When to Plant

You can successfully start a new kumquat plant by planting the seed in spring. Spring is the ideal time for kumquats as the temperature is pleasant with higher chances of rain and, of course, lots of sunshine. Early spring is also the best time to transplant a sapling kumquat.

Where to Plant

Plant in a place where there’s full sun. You can plant them in your backyard or outside on your patio as long as they get well-drained soil. They also do well in pots or containers with suitable drainage holes, but will grow much better if directly planted in the ground. If you must grow them in a container, try an Air Pot, which is expertly-designed to cultivate a healthy root structure. Choose a location where your tree is protected from high wind conditions if possible.

How to Plant

It’s better to purchase a kumquat tree from a local nursery. Kumquat can sprout from seed, but the plant is mostly weak. Choose a sunny spot and plant the tree in spring to ensure that the kumquat is well-established before winter arrives.

After choosing the spot, dig a hole at least 3-5 times wider than the root ball. Carefully place the tree into the hall and ensure that the soil is level with the ground. Tap down the soil for a smooth layer.

Since kumquats need regular hydration, water the plant thoroughly and don’t let the soil become dry. Mist often, at least a few times a week, until the tree establishes.

Add organic mulch to the surrounding area, about 2-3 inches, while keeping the mulch at least 10 inches from the trunk.

Ensure proper watering and soil conditions for about a month and then fertilize. You can use a high-quality citrus formula.

Kumquat Tree Care

A kumquat tree full of fruit I harvested from this past summer.

Kumquat tree, particularly the variety known as nagami kumquat, is relatively easy to grow. However, like other citrus trees, it can’t survive on neglect. When you’re planting the tree, it’s essential to treat it with a lot of care. The journey is extremely rewarding once the kumquat tree begins to bear delicious citrus fruit. Here’s a breakdown of how to nurture and look after it. 

Sun and Temperature

As mentioned earlier, kumquats are best grown in full sun. They need at least 6-7 hours of sunlight every day for healthy root development, and 8-10 is better. If you’re growing them indoors, make sure to keep them near a window for maximum sunlight, or provide a grow light to keep them healthy.

Kumquats do well in USDA hardy zones 9 and 10 and can survive in temperatures as low as 18 degrees F (-7 degrees C). If temperatures drop lower, bring them inside.   


The key to growing any citrus fruit tree is proper watering. If you’re growing kumquats in pots, the soil needs to be moist but not wet. For this, you must ensure the container has suitable drainage holes and that the soil itself drains excess water away. 

Kumquats need regular watering, especially when the plants are young – you’ll often water 2-3 times a week throughout the first year. However, make sure not to overdo it for older trees.

To check for hydration, stick your finger at least 3-4 inches in the soil; if you feel dampness, wait until the soil dries out a little to water again. However, if it’s dry, water the tree until water begins to run out from the bottom of the pot. Trees planted directly in the soil should be watered until the soil’s moist, but not muddy. A soaker hose can help.


Kumquat tree survives well in almost any soil pH. But it can’t survive really sticky, clay-like soils that don’t drain readily. Ensure your soil easily drains away water. If you’re growing in a container, a citrus potting blend is great. Those growing directly in the ground should do a drainage test first.

To do a drainage test, dig a hole at least a foot deep, and fill it with water. If it empties out within about 20 minutes, your soil’s perfect. If the water stays in the hole for over an hour, it may be best to work through some compost or other drainage aid. Even a small amount of sand can improve drainage, but perlite is another good option. 


Apart from the cold winter months, kumquat plants need regular fertilizer. In spring, feed the plant with an all-purpose, slow-release citrus fertilizer. As the plant grows, give it diluted liquid fertilizer, like fish emulsion or liquid kelp on an occasional basis. Always water well before applying liquid fertilizers. Avoid getting fertilizer on the tree itself, only on the soil.


Kumquat tree doesn’t require much pruning except when you have to remove dead or damaged branches that may be sucking up the tree’s resources. If you want to shape the tree, make sure to do so before the flowering season in spring and after harvesting the fruit. 

An occasional pruning to open up the canopy can allow more light and airflow into the upper part of the tree. This helps with future flowering and reduces the chance of diseases taking hold.

Propagating Kumquat Trees

The trees aren’t generally grown from seeds, although they can be. The tricky part about seeds is that you won’t necessarily get an exact clone of their parent plant. If you’re trying to raise a particular cultivar, it’s best to go with another method.

Propagate instead by grafting young branches onto the rootstocks of grapefruits and oranges.  The root systems of most grapefruit and orange trees are typically more resilient to fungal diseases in the soil.


When growing kumquat trees in containers repot every 2-3 years in containers that are at least a few inches bigger than the previous one. The ideal time for repotting is the early part of the leaf-growing stage in spring. 

Harvesting and Storing

Here’s how you should harvest and store the fruit from kumquat trees. 


The harvesting time for most varieties begins from November through January, while for others, it’s from December to April. The fruit is ripe when it’s slightly soft and deep orange. Pick the fruit using scissors or pruning snips to avoid damaging the plant. You can also trim the fruit along with a small piece of the branch. 


Kumquat fruits don’t have a long shelf life because they have thin, delicate peels. If you want to store them for a week or so, keep them in fully covered paper bags or plastic bags at room temperature. However, it’s best to store the fruit in the fridge. 


Even when kumquat trees require lots of care, gardeners don’t face many growing problems.

Growing Problems

After extreme freezing conditions, your kumquat may experience loss of leaves. While they’re hardy down to about 20 degrees Fahrenheit, colder conditions can cause this to happen. Try to keep your tree protected from excess cold whenever possible. Drastic changes in light can also cause leaf drop.

Container-grown kumquats can experience twig dieback and loss of leaves if they become rootbound. Try to prevent this problem by ensuring that the pot’s large enough to satisfy your tree’s needs.


Kumquat trees are susceptible to mealybug infestations, leaf miners, citrus scale, and aphids. Keep the soil well-drained and avoid excess moisture and piling too much mulch around the tree. A good insecticidal soap or a robust horticultural oil or neem oil will help combat the infestation.  


Anthracnose is a common citrus disease. This leaf spot disease can be prevented by spraying the tree three times annually with horticultural oil. If it appears, most copper-based fungicides will clear it up. You may also encounter alternaria leaf spots, and those should be handled similarly to anthracnose.

Citrus blast is a bacterial infection that spreads in parts of the US after wind-driven rain. The bacteria, Pseudomonas syringae, enters into the plant via points of damage from the wind. It causes withering of leaves and can lead to complete death of the plant. Plant your citrus trees with protection from wind, and use a copper-based fungicide to kill off bacteria.

Phytophthora root rot is another issue that may appear. This is usually a fungally-based root rot that is caused by overly-soggy soil conditions. Do not overwater your trees, and you should not encounter this problem.

Frequently Asked Questions

Q. Where do kumquats grow in the USA? 

Kumquat trees are most often grown in Florida and California. 

Q. What are the benefits of eating kumquat fruits?

Kumquat fruits are incredibly high in vitamin C and fiber. Eating them can help strengthen the immune system and support weight loss.

The Top 5 Reasons Why Your Kumquat Tree Isn’t Fruiting – Couch to Homestead

My parents have a kumquat tree and it recently seemed to have delayed fruiting, so we looked to some reasons that could be causing it. While we came across many possible causes, there were a few that were recurring and made the most sense. Here’s what we found.

The best ways to encourage a kumquat tree to fruit are to provide proper sunlight, watering, nutrients, and pollination. Also, allow the tree to reach full maturity and to check the fruiting season. Keeping two or more kumquat trees increases the fruit size and yield, and reduces dropped fruit.

Let’s take a closer look at how you can get your kumquat tree to fruit.

1. Let It Mature

It may seem basic, but sometimes your kumquat tree just needs more time to produce fruit. Plants often need to reach a certain level of maturity before they start to flower.

Kumquats will start to bear fruit in as little as 2-3 years if they’re grafted, or as long as 15 years if they’re grown from seed. If you have a kumquat tree that hasn’t fruited yet, it could very likely be that it’s too young. For quickest results, opt for a grafted kumquat tree over one grown from seed.

The amount of time for a kumquat tree to mature varies depending on whether the tree was grafted or grew from a seed. Grafting the bud of a younger tree to an already mature rootstock lessens the amount of time required to reach fruit-bearing age.

This process also helps guarantee that you can still get blossoms even on a small plant.

Also, recently transplanted trees will often focus on growing roots instead of producing fruit. This can take anywhere from 3-5 years after being relocated before the root system is matured enough to start to grow fruits.

One strategy to speed up fruiting is to prune some branches to encourage the tree to focus on fruit production instead of growing foliage. This also helps prevent leaves from crowding airflow around the tree which can discourage flowering.

However, it is possible to over-prune kumquat trees. If you prune too much, all of the energy from the tree will be focused on leaf regeneration in efforts to survive.

2. Check The Fruiting Season

Kumquat trees bloom in the early summer and their fruits ripen sometime between December to March. If your tree isn’t getting flowers, check its sunlight, watering, and nutrients. If the tree isn’t mature enough, or stressed, it won’t produce flowers.

Generally, kumquat trees need at least six hours of full and direct sunlight to produce flowers.

3. Water Properly

While it seems simple, avoiding over or under-watering your kumquat tree can be a difficult balance. Ideally, the soil should be moist, but not soaking wet.

Generally, young sprouts should be watered a couple of times per week, but mature plants don’t need to be tended as often.

A good way to check if your plant needs to be watered is to stick a finger in the first 2-4 inches of soil and to see if it is still damp. Wait until the soil is dry to water again.

Additionally, kumquat trees thrive in humid environments, so if your plant is indoors try misting the leaves to prevent them from drying out and curling.

Also, check that the soil is well-drained. For indoor trees, this can be done by choosing a pot with good drainage. For outdoor trees, be sure to not use clay-like soils that aren’t capable of draining.

Clay soil will keep the plant sitting in water and will result in root rot. One way to check if your soil drains well is by doing a drainage test. This is done by digging a 1-foot by 1-foot hole and filling it with water. If the hole drains slower than 2 inches per hour, it has poor drainage.

Overall, the best way to water citrus is by deep-watering. Deep-watering is the process of providing more water in less frequent intervals. This trains the kumquat tree to grow longer roots and become more drought-resistant. It also means you don’t have to water as often, so it’s a win-win!

4. Provide Balanced Nutrients

Kumquat trees need the appropriate nutrients to root, leaf, flower, and grow fruit. For kumquats, and most citrus trees, the most critical nutrients are nitrogen, magnesium, phosphorus, and potassium.

One way to tell if your plant is receiving the proper amount of nutrients is to study the leaves.

Pale foliage usually means a lack of nitrogen, and yellow leaves can suggest a wide number of issues.

Chlorosis, or yellow leaves with green veins, often means that your kumquat tree needs more zinc.

And yellow leaves starting at the top of the tree instead of the bottom usually implies a lack of potassium, iron, or magnesium.

Lastly, know that zinc is necessary in small amounts to help produce chlorophyll and enable photosynthesis. Enough zinc can usually be provided through the soil that your tree is planted in.

If you believe your kumquat tree is lacking nutrients, try using a complete, organic citrus fertilizer or quality compost. However, since compost has a neutral pH, you may need to mix in some coffee grounds, sand, or peat moss to increase the acidity slightly).

Keeping a properly balanced pH is also necessary for proper fruiting on Kumquat trees. Like most citrus trees, kumquat trees can be planted in soils with a wide range of pH values. However, slightly acidic soil with a pH of around 6-7 is the best balance for kumquat trees.

At too high or too low pH values, most of the nutrients are less available to the tree. In fact, higher acidic soils can reach toxic levels of nutrients.

A well-balanced pH in the soil provides the right amount of nutrients to support growth and fruiting.

5. Increase Pollination

Kumquat trees are self-pollinating, so they don’t need another citrus tree nearby to produce fruit. However, they can still benefit from cross-pollination, which increases the amount and size of the pollinated flowers and fruits.

You can increase cross-pollination by planting companion plants, beekeeping, or manually pollinating (with a clean q-tip, toothbrush, or paintbrush).

Pollinators such as bees, birds, and butterflies, carry the pollen from male to female flowers. Without pollination, the tree will flower but won’t produce kumquats.

Sometimes outdoor kumquat trees still don’t get enough pollination. One way to increase the likelihood of fruit production is to plant flowers in your garden. This can help attract more pollinators to the kumquat tree’s vicinity and increase pollination levels.

Additionally, planting more citrus for improved cross-pollination can help, but it’s not necessary.

Although rare, some kumquat trees might need to be pollinated by hand to trigger fruit production. This can be done with a toothbrush or a paintbrush.

When you move the brush around the center of each flower around the plant, you are acting as the pollinator.

To learn more about pollination, and how to improve it for your citrus trees (including kumquats), check out my post on citrus tree pollination.

Final Thoughts

To recap, the top five reasons for a lack of kumquat fruit production are:

  1. Age 
  2. Season 
  3. Water
  4. Nutrients
  5. Pollination 

Whether you’re growing your kumquat tree inside in a pot or outdoors in a garden, these factors can greatly affect your tree’s growth and fruiting ability.

Provide 6+ hours of sunlight, only water when the top 2-4 inches of soil is dry, provide a balanced fertilizer, and increase pollination when you can.

Following these best practices will give your kumquat trees the best chance of flowering and fruiting!

General description of the plant

Kumkvat is the birthplace of the Kumkvat. From there, the plant was later introduced to America and Europe. Its name translates as "golden orange". In Japan, another name for the fruit is Kinkan (golden apple).

Kumquat is a very beautiful plant with delicious fruits

The plant is a small tree. At home, it grows up to 1.5 m, and in the wild - up to 4.5 m. The kumquat crown is strongly branched, dense, densely leafy. The leaves are small, smooth, dark green. The kumquat blooms with white fragrant flowers with a rose. Flowers are arranged singly or in inflorescences. The fruits are somewhat reminiscent of tangerines, only much smaller. Their weight does not exceed 30 g, the skin is thin, bright orange. The taste of kumquat fruits is balanced, thanks to the fragrant sweet skin and sour pulp.

2-3 months after flowering, the tree begins to bear fruit. The fruits ripen in late winter - early spring. During this period, the kumquat becomes more decorative, as can be seen in the presented photos.

Nagami Kumquat

Varieties and varieties of kumquat

The Nagami kumquat (Nagami Kumquat) is the most common when grown at home. Outwardly, it is a very decorative plant and is used in the design of bonsai gardens. Its crown is compact and completely strewn with bright orange fruits during the fruiting period. There are garden forms of Nagami kumquat:

  • Nordmann Nagami is a seedless subspecies similar in appearance to Nagami.
  • Variegated - characterized by yellowish or creamy leaves. The fruits first have longitudinal green stripes that disappear when ripe.
Variegated kumquat
  • Marumi kumquat (Marumi Kumquat) is distinguished by the presence of thorns on the branches. The size of the tree of this species is somewhat smaller. The fruits are golden-orange when ripe, with small seeds. The plant is conditionally winter-hardy. In the southern regions it is able to grow in open ground.
Marumi Kumquat
  • A lesser known species of kumquat Meiwa (Meiwa Kumquat) produces fruits with the most intense taste. The tree is very decorative, dwarf, with a dense crown and small hard leaves. The fruits are relatively large, outwardly resembling a lemon. The peel is golden, sometimes with shades of yellow.
Meiwa Kumquat
  • The largest fruit can be found in the variety Fukushi (otherwise Changshu, lat. Fucushii Kumquat). The tree grows a meter or a little more in height, while its crown is sprawling, dense. Its leaves are larger than those of other members of the genus. Fruits can be both oval and pear-shaped. Dessert flavored juicy pulp is surrounded by a thin, very sweet orange skin.
Fukushi kumquat
  • Kumquat Hong Kong (Hong Kong Kumquat) is characterized by dry fruits, the size of a pea. The fruit of this kumquat is practically not eaten. On its branches are numerous long prickly thorns.
Hong Kong Kumquat
  • There is another type of kumquat that is not grown at home - Malayan (MalayanKumquat). At home, it is grown as green hedges. It is distinguished by its impressive size and large golden fruits.

In addition to varieties of kumquat, there are a number of interspecific hybrids:

  • calamondin - a hybrid obtained by crossing a kumquat with a mandarin;
  • limequat, a hybrid of kumquat and lime;
  • orangequat - a hybrid of kumquat and orange.

Planting and caring for kumquats

Kumquats grow in 1-2 months starting in April. The annual growth is up to 10 cm. A young plant gives two growths per year, which distinguishes the kumquat from other representatives of citrus fruits. The tree blooms in the middle of summer for a week. Flowering may occur again after 2-3 weeks. At home, the flowering of the tree must be normalized. By the end of winter, exotic fruits ripen on the kumquat.

With proper care, the tree will bear fruit in winter

Location. Kumquat should be allocated the sunniest place in the house. In summer - create conditions for diffused lighting, you can take it out to the street or balcony. In winter - as much direct sunlight as possible and, if possible, cool air.

Attention! In order for the kumquat to have a miniature size, a small container is taken for planting. For the full development of the tree, voluminous pots are used.

Soil. For planting kumquat, a soil mixture of soddy and garden soil, leaf humus and river sand is used.

Water the kumquat abundantly.

Watering. Kumquats are very fond of watering. They should be plentiful and regular, but without stagnant moisture. In the summer heat and the period of central heating turned on, the plant needs frequent spraying and wiping the leaves with a damp cloth. With excessively dry air, the tree begins to hurt and shed its leaves. It would also be useful to “take a shower” with a kumquat that imitates natural rain.

Attention! Watering should be carried out only with warm water. Otherwise, the tree will shed its foliage.

Cut . Spring is the period of kumquat crown formation. To do this, 2-3 shoots are left on the main branches, the rest are removed. The left shoots are shortened a little, thereby stimulating the growth of young shoots.

Transplant. Once every two or three years, the plant needs to be transplanted. They do this by transshipment so as not to disturb the earthen clod. The soil and drainage layer in the pot must be changed to new ones.

Attention! Transplantation is carried out in early spring before growth begins.

Top dressing and fertilization

Without regular top dressing, the kumquat will not bear fruit. The frequency of fertilization depends on many factors:

  • the age of the tree and its condition;
  • soil used for cultivation;
  • pot sizes.

So, if the kumquat pot is small, you need to feed more often.

During the growth period, the kumquat is fed every ten days with phosphorus-potassium fertilizers. During the dormant period, the number of dressings is reduced to once a month.

Fertilizers are also necessary for fruiting and normal development of the plant

Optimal composition of complex fertilizer (per 1 liter of water):

  • ammonium nitrate - 1/4 teaspoon;
  • potassium chloride - 1/8 teaspoon;
  • simple superphosphate - 1/2 teaspoon.

Responsive kumquat and wood ash infusion.

Diseases and pests

Kumquat is affected by many diseases inherent in citrus fruits. Symptoms of trouble can be:

  • leaf spots;
  • changes in the shape and color of the leaves;
  • shoot panicle;
  • tree shrinkage;
  • build-up.
Spotting on kumquat leaves

Fungal and bacterial diseases (anthracnose, wart, gommosis, etc.) can be cured. If the plant has buds or fruits, they must be removed to save the kumquat's strength. Further, repeated treatment with fungicides is carried out. During this period, it is important to properly care for the tree, restoring its vitality.

Tip. To prevent the development of fungal and bacterial diseases, kumquat can be treated with a 1% solution of Bordeaux mixture 2-3 times during the growth period.

A tree affected by a virus (xyloporosis, trispeza, etc.) cannot be cured.

In an unfavorable indoor climate, kumquats are attacked by aphids, spider mites, scale insects and other sucking pests, which are controlled with special preparations.

Kumquat propagation

Kumquat can be propagated in several ways:

  • seeds;
  • cuttings;
  • rooting cuttings;
  • grafted on rootstocks.

Grown from seeds, young plants do not retain maternal qualities, start bearing fruit late. This method is mainly used by breeders to develop new varieties and grow rootstocks.

Kumquat seedling

Propagation by cuttings is most acceptable at home. Cuttings are cut in the spring, picking up short young shoots of the last year on a fruit-bearing kumquat. The leaves are cut in half. Root cuttings in wet sand, covering the container with glass or film. An impromptu greenhouse is opened from time to time to ventilate the seedlings.

For the speed of rooting cuttings, planting material can be treated with any growth stimulant.

Rooted cuttings are planted in pots with earth. Further care for the seedling is carried out as for an adult plant.

It is quite possible to grow a kumquat at home, providing it with proper care. As a result, you will get not only an elegant decorative tree, but also tasty, healthy fruits.

  • Kumquat is a beautiful plant with useful golden fruits. Kumquat belongs to the subgenus Fortunella, Rutov family. An ornamental plant was brought into the country from China relatively recently and immediately became popular. Kumquat in a flower pot looks attractive, reminiscent of a miniature tree or shrub. Growing kumquat at home is an interesting and easy task, even a novice florist can handle it. By following simple rules, you can grow a tropical plant with fragrant flowers and useful, beautiful fruits.

    Which varieties of kumquat can be grown at home

    Under natural conditions, kumquat grows in southern China, the tree height reaches 5 m. At home, the height of the plant depends on the size of the pot. The plant forms a strong root system and a spherical crown. Kumquat blooms in the first half of summer, numerous snow-white-pink flowers with a pleasant citrus aroma appear on the tree.

    After flowering, orange fruits weighing up to 30 g appear on a domestic kumquat plant. They taste like tangerines, but there is one difference - kumquats are eaten with a peel, as it is soft and has a sweet taste.

    At home, in flower pots, you can grow several unpretentious, miniature varieties of kumquats.

    Nagami. A popular, common variety of kumquat, which can be grown both in apartment conditions and in the backyard. An ornamental tree produces sweet-sour fruits, the size of an olive. The variety has 2 subspecies:

    1. Variegatum - green peel is painted in original horizontal stripes that disappear during ripening.
    2. Nordmann is a seedless variety of kumquat.

    Tip! The Nagami variety is ideal for those who like to grow Bonsai.

    Marumi. Low-growing kumquat variety, forms a miniature tree-like shrub, with thorny shoots. Small, oval fruits are golden in color, have a sweet and sour taste and a pleasant smell. The variety is frost-resistant, therefore, in regions with a warm climate, it can be grown as a street plant.

    Meiwa. A dwarf variety of kumquat, the height of the tree reaches half a meter. Due to its decorative appearance, rather large bright yellow fruits with a sour taste, the variety has become popular with flower growers.

    Fukushi. The variety is suitable for flower growers who have experience in growing kumquats in an apartment. The plant forms a dense dark green crown, among which large, sweet fruits with a thin peel appear in the middle of summer. The Fukushi variety is ideal for growing in greenhouses and winter gardens.

    Obovata. Dwarf, thornless kumquat variety, with a delicate emerald crown. Flowers appear on annual shoots from June to October. Snow-white inflorescences reach 2 cm in diameter, very beautiful and fragrant. The fruits are small with a thin skin and sweet and sour, spicy pulp.

    What conditions should be created for plants

    To grow kumquat at home, you need to create comfortable conditions for growth, development and fruiting. In summer, kumquat prefers to grow in diffused light, in a place protected from drafts. If the weather is warm, then the flower pot can be moved to a balcony or garden plot.

    In winter, kumquats need a lot of light, so they choose a warm, sunny place for this. If the windows face the west or north side, the flower must be illuminated.

    Important! For good growth, the summer temperature should be within + 25 ° C, in winter + 18 ° C.

    Kumquat grows well in high humidity conditions. If the air is dry, as a rule, it comes in winter, when the heating is turned on, the kumquat begins to shed its leaves. To increase the humidity of the air, it is necessary to spray the plant once a week, install a container of water or an air humidifier next to the flower pot. If the temperature is cold in the apartment, then kumquat is not sprayed, since at high humidity and low air temperature, fungal diseases often appear on the plant.

    How to grow kumquats at home

    Kumquats are grown from:

    • seeds;
    • cuttings;
    • bends;
    • by inoculation.

    When propagating kumquat by seeds, it will take a long time to bear fruit, and when eating the fruit, the taste will be below average.

    Propagation by grafting and branching is a difficult and time-consuming process, therefore it is not suitable for beginner growers.


    For propagation of kumquat, a one-year-old, strong shoot, 20 cm long, is selected with branches. 2 annular cuts are made on the trunk and the bark layer is carefully removed, exposing a round area. Leaves above and below the cut are removed.

    A plastic bottle is needed for rooting. The container is cut in the center, a hole is made at the bottom equal to the diameter of the shoot. The shoot is placed inside, the container is filled with nutrient soil and both parts are fastened with tape.

    After 60 days, the shoot will grow the root system, and after separation from the mother bush, it will be ready for transplanting to a permanent place.

    By seed

    Seed propagation is a simple, popular way to propagate kumquats. Even an inexperienced grower can grow a plant from a seed. The main thing is to know that a young kumquat grown in this way will develop for a long time, and the first harvest can be obtained only after 10 years.

    How to make a kumquat cutting root

    Kumquat can be propagated by cuttings all year round, but the best time is mid-April, before flowering begins. In order for the cutting to form a root system faster, it is treated in a growth stimulator (Kornevin or Epin) before planting.

    How to graft a kumquat at home

    Grafting is a complex, time-consuming way of propagating kumquats, therefore it is only suitable for experienced flower growers. As a rootstock, grapefruit, lemon, orange, trifoliate or poncyrus are suitable.

    The kumquat can be grafted by budding or with a butt shield during active growth. For reproduction, a healthy seedling with a diameter of about 2 cm is chosen. After 50 days, the seedling will get stronger and grow the root system. To make the tree look decorative, formative pruning is carried out, removing all shoots above the grafting site.

    A kumquat grown in this way bears fruit after 10 years, but growth and development is much faster. The grafted kumquat has a strong immunity to many diseases and sudden changes in temperature and humidity.

    Planting rules

    Growth, development and fruiting time depend on the correct planting of the kumquat. By choosing the right breeding method and having a little patience, you can grow a kumquat indoors.

    Growing kumquat at home from stone

    Growing kumquats from seeds at home is not difficult if you follow certain rules. This is a long process that requires patience and endurance from the grower.

    1. Pour a 15 cm layer of drainage into the flower pot and fill it with nutritious, well-drained soil.
    2. Seeds are soaked in a growth stimulator for several hours for better germination.
    3. Prepared seeds are buried in moist soil by 1.5-2 cm.
    4. For rapid germination, the pot is covered with polyethylene, creating a greenhouse effect.
    5. Seedlings appear after 10 days.
    6. After the appearance of 4 leaves, the plant is transplanted into a larger pot. To quickly build up the root system, the roots are shortened by 0.5 cm.

    Important! Kumquats grown from seeds will begin to bear fruit in 10 years.

    How to plant a kumquat cutting at home

    Kumquat cuttings are a simple, effective way of propagation. Suitable for rooting are 10 cm flexible, green shoots cut from fruit-bearing plants.

    The lower cut, made at an acute angle, is treated in a growth stimulator and sprinkled with ash. The bottom of the flower pot is covered with expanded clay, covered with wet moss and nutrient soil is added. Several cuttings are placed in a pot to a depth of 2 cm, covered with a glass cap and cleaned in a warm, sunny place. After a month, rooting occurs, and the cuttings can be planted in separate containers.

    How to care for kumquat at home

    Citrus kumquat is a demanding plant, so care at home should be timely and carried out according to certain rules. For rapid growth and development, as well as for beautiful flowering and good fruiting, it is necessary to timely water, fertilize and form pruning.

    Watering schedule

    The frequency of watering kumquats depends on the season. In autumn and spring, irrigation is carried out moderately, in winter watering is reduced, in summer - as the soil dries out. Watering is carried out in the morning with warm, settled water. When irrigated with cold water, the plant will shed its leaves and root rot may develop.

    The need for watering can be determined by the soil. If it dries to a depth of 4-5 cm, then it's time for watering. After half an hour, the excess water formed in the pan is removed.

    How to feed the kumquat

    Without regular feeding, the kumquat will grow well and will not bear fruit. Feeding depends on several factors:

    • pot size;
    • soil quality;
    • plant age.

    From March to October, during active growth and fruiting, fertilizers are applied several times a month. To do this, use liquid top dressing intended for citrus plants, diluted strictly according to the instructions. You can also use 2.5 g of ammonium nitrate, 1.5 g of potassium salt and superphosphate, diluted in 1000 ml of warm water.

    Important! In winter, kumquats are fertilized once a month.

    How to prune a kumquat at home

    In order for a kumquat to have a decorative appearance and begin early fruiting, it is necessary to prune the crown. First of all, the trunk is formed. To do this, it is cut at a height of 20 cm, leaving 4 or more well-developed buds. Further, stem branches will begin to form from these buds, which will become the basis of the tree and will be branches of the first order. Each next order should be shorter than the previous one by 5 cm.

    When a kumquat bears fruit

    To increase and speed up fruiting, you need to know the simple subtleties of how to make a kumquat bloom:

    1. Cultivation method - for early fruiting, kumquats are grown from cuttings. In this case, the first fruits will appear 5 years after planting.
    2. Regulate flowering and ovary formation - a large number of inflorescences takes a lot of energy from the kumquat, which prevents the formation of full-fledged ovaries. The maximum number of fruits is 1 per 10-15 sheets.
    3. Care - regularly fertilize with complex mineral fertilizers.

    Kumquat is a late-ripening citrus species. Flowers appear in July, then after 14 days there is a second abundant flowering. Orange fruits ripen in late winter, early spring.

    Transplanting kumquats at home

    The frequency of transplanting depends on the age of the kumquat. One-year-old specimens are transplanted 2 times a year, a plant at the age of 3 years - 1 time, an adult kumquat is transplanted no more than 1 time in 3 years. You can determine the time by the roots formed from the drainage holes. The optimal time for transplanting is the dormant period, after harvesting.

    Transplantation technique:

    1. Like any citrus plant, the kumquat prefers nutrient-rich soil. You can buy it, or you can mix it yourself. To do this, combine sand, peat, humus and garden soil. For an adult plant, the ratio is 1:1:1:1, for a young kumquat, the amount of sand is increased by 2 times.
    2. Before planting kumquat in self-prepared soil, it must be chemically or thermally disinfected.
    3. The pot is selected 2 cm more than the volume of the previous one.
    4. The bottom is covered with expanded clay and the plant is transferred to a new pot by the transfer method. The voids are filled with nutrient soil, lightly tamping it.
    5. Experienced flower growers recommend mulching the top layer with peat or decontaminated tree bark to preserve moisture.
    6. It is impossible to deepen the kumquat strongly, as the citrus will start to hurt and may die.

    Disease and pest control

    Kumquat is a capricious plant that develops well at high temperature and humidity. If the rules of care are not followed, the kumquat, like any citrus fruit, can be susceptible to diseases and attacked by pests.

    How to deal with pests on the kumquat tree

    The main pests of kumquat are:

    • aphid - affects the leaf plate and young shoots;
    • thrips - destroy the entire green part of the kumquat;
    • spider mite - affects young foliage and root system;
    • scale insect - settles on the trunk, branches and fruits of the kumquat;
    • nematodes - affect the root system.

    Important! When grown in a home garden, kumquats are often attacked by ants.

    You can fight insects with folk remedies together with insecticides. As folk remedies, a decoction of hot pepper, a tobacco-alkaline mixture, an ash alkaline solution are used.

    How to treat kumquat from diseases

    All insect pests are carriers of dangerous diseases, such as:

    • Anthracnose - a fungus that affects leaves, fruits and branches. Leaves and flowers fall, red spots appear on the kumquat fruits.
    • Gommosis - red spots appear on the tree trunk. If you do not start treatment, the bark will begin to die, and gum will flow from the affected area. The disease often appears with deep planting, in the presence of mechanical damage and poor drainage.
    • Citrus wart - the disease affects the fruits, leaves and young shoots of kumquats. The foliage is covered with small yellow spots, which eventually turn into wart growths, the young kumquat branches dry, blurry orange spots form on the fruits.

    Kumquat diseases can be treated with fungicides. For prevention, 3 times a year, kumquat is sprayed with 1% Bordeaux liquid.

    Growing problems

    Some problems may arise when growing kumquats. Very often, the leaves of the plant dry, the ovaries fall off, flowering and fruiting do not occur

    Why does the kumquat shed its leaves and what to do

    The kumquat begins to fall when there is a lack of moisture, low air humidity, and if the plant is not given a dormant period with a decrease in air temperature. In order for the kumquat to go into hibernation, the pot is moved to a bright, cool place, and watering is reduced.

    Also, leaf fall may begin immediately after purchase. This is due to a change in the conditions of detention. To stop the fall of foliage, the kumquat is transplanted into a new substrate, all ovaries and fruits are removed, the earth is shed with warm water with the addition of a growth biostimulator. You can also cover the crown for 10-14 days with a plastic bag.

    Why do kumquats dry at home

    Quite often kumquats begin to dry out at the tips of the leaves.
