Soil for a coffee tree: how to choose the composition of the soil and what to feed the plant with? Selo.Guru

general description

Coffee trees belong to the Rubiaceae family. Traditionally, they are divided into several types according to the type of grains obtained. For the consumer, the difference comes down to taste. Most coffee comes from a plant called Arabian coffee (or Arabica) , the second most popular species of Congo coffee (or Robusta). The taste of the latter has a fairly pronounced sourness.

Coffee tree in nature. Ethiopian Harar variety, Arabica

Typically, Arabica is a low-growing plant, and Robusta is a tall plant . But under different growing conditions, it is quite possible that the growth of Arabica will not be inferior to that of Robusta (for example, Arabica grown in the Hawaiian Islands).

Congolese coffee. Karamu variety, Robusta

The fruits of the coffee tree, or coffee beans, are structured exactly the same for all representatives of coffee trees and differ only in size and flavor. The core of coffee beans, actually the seed of the fruit, is the very substance from which the well-known drink is obtained. Depending on the type of coffee tree, from each of them you can get from 0.2 to 10 kg of coffee beans per season.

Opened coffee fruit with two beans inside

There are about a hundred species of the Rubiaceae family in the world, growing in different parts of the globe.

Some of them can be adapted for growing at home in our area. The main problem in growing is not providing the temperature or lighting conditions for the coffee tree; coffee thrives at temperatures from +20°C to +24°C and can be grown in the shade.

The problem is creating the necessary atmospheric pressure for growing coffee, because under natural conditions it grows at altitudes from 900 to 2500 meters above sea level; and this is neither more nor less, a few hundred millimeters of mercury difference. However, this is only critical for industrial coffee growing. We are not chasing an abundant coffee harvest in a temperate continental climate, are we?

Preparing the soil for cultivation

Coffee loves acidic soils, which corresponds to the conditions of its homeland. The pH level for coffee should be between 4.5 and 5.5. At the same time, some gardeners recommend using soils for azaleas, hydrangeas or rhododendrons for coffee trees at home. However, you should pay attention to the acidity level.

If it is slightly higher than recommended (for example, soil pH for azaleas is 4.0), it can be used to grow a coffee tree, but if the soil is highly acidic (pH = 3.5), then it is better not to do this.

Fruiting coffee tree (Arabica), grown at home

Sometimes inexperienced gardeners purchase soil suitable for growing citrus fruits for a coffee tree. It is only partially suitable for the coffee tree, since its composition is acceptable, but it is more neutral than slightly acidic. You also need to know that approximately six months to a year after the start of active growing season, the soil under the coffee tree changes its composition and ceases to be acidic, shifting to neutral acidity.

In both of the considered cases, to ensure a normal acidity level for coffee, it is recommended to “acidify” the soil once a month. This is best done with lemon juice in a concentration of 3-4 drops per 1 liter of water. If you don’t have lemon on hand, you can use citric acid (2-3 grains per 1 liter of water).

The roots of the coffee tree are quite long, penetrating deeply into the soil. To ensure they have adequate supply of nutrients and air, it is necessary to use well-drained and loose compounds. The matted soil must be loosened and humus or peat added to it (depending on the acidity).

You can prepare the soil yourself. For this you will need:

turf soil – 1 part
leaf soil - 1 part
humus - 1 part
coarse river sand – 1 part
peat – 2 parts

Sometimes it is recommended to add 0.5 parts of sphagnum moss to this composition for greater looseness.

Caring for a coffee tree at home

When caring for a coffee tree at home, you need to take into account several important nuances that will ensure active growth, lush flowering and abundant fruiting of the exotic plant.

Despite the fact that the plant grows in the tropics, it does not need direct sunlight. If the light is too bright and the air temperature is too high, it will not bloom. It is best to place the tree on a western or northern window with diffused light. When placed on a windowsill on the south side, the flower pot should be at least 1-2 m from the window.

When growing an exotic plant, you need to remember that a coffee tree in a pot does not tolerate any movement in space very well. That is why the pot with the plant can be moved no more than once every 4-5 years, otherwise it will drop flowers.

Air temperature and humidity

When caring for a coffee tree at home, attention should be paid to maintaining optimal temperature and humidity. In the summer, the plant grows actively at temperatures from +22°C to +30°C. In the winter months it should not fall below +13°C.

The coffee tree requires high air humidity - at least 70%. To do this, on summer days the plant needs to be sprayed with clean, settled water; in winter, additional irrigation is not required if the flower pot is placed away from heating radiators.

Pot and soil

To grow a coffee tree, you need to choose a container that is slightly larger than its root system. The pot shouldn't be too big. The best option is if it is 3-5 cm larger than the earthen lump with the roots of the plant. Otherwise, the soil in the container begins to acidify, leading to the death of the root system of the coffee tree.

The soil for the coffee tree should be loose and breathable. You can prepare it yourself:

peat, humus, garden soil and river sand (in equal parts);
peat, turf soil, river sand, manure humus, leaf soil, sphagnum moss (1: 4: 2: 2: 4);
peat, leaf turf and coarse river sand (2:1:2).

To care for a coffee tree at home, you can also use store-bought nutrient substrates - a citrus substrate best meets the requirements of an exotic plant.

Planting coffee seeds

Coffee can be grown either from seeds or from cuttings. Cuttings, of course, are preferable, since it is quite possible to make it bloom and bear fruit in the first year, however, they are not always possible to find.

Coffee seeds

Coffee seeds have relatively good germination, but only in the first days, sometimes weeks after being picked from the branches. Over time, germination deteriorates significantly. Therefore, if you buy grains for planting, their quantity should be quite large.

The percentage of germinated seeds for coffee is generally considered to be around 10%.

Seeds are prepared for planting as follows: the grain is cleared of the outer shell and soaked in a 0.2% solution of potassium permanganate. After which it is dried and planted in a small individual pot.

Arabica young shoots

Later, when the shoot grows enough, it is transplanted into a stationary pot. The composition of the soil in pots should be the same as for growing an adult tree.

Planting is carried out according to the standard scheme: a third of a small pot is drainage (egg shells, small pebbles, gravel), then soil is laid in which a hole 1 cm deep is made. The grain is placed in this hole with the flat side down and covered with a layer of soil. This position of the grain will allow it to break through to the surface with less problems.

Sprouted coffee beans

After planting, it is recommended to create greenhouse conditions for the grains (humidity about 90-95%, temperature about +25°C). Such conditions can be achieved either in a mini-greenhouse, or by placing pots with grains in the sun and covering them with plastic film or glass. Once a day, it is necessary to ventilate the soil surface by removing the film or glass for 5-10 minutes.

Planted grains are watered abundantly, however, watering must be done using a tray. It is prohibited to pour water from above onto the ground. Watering is carried out once every 2-3 days; The criterion for the need for watering is dry soil on top of the pot. The soil should not be allowed to dry out.

How to care for a potted Arabian plant

When the planted seed has sprouted and the first green shoot is clearly visible, it’s time to start studying the growing conditions of Arabica. This Arabian tree requires special care.

Let's look at the main nuances of how to care for Arabica coffee:

The tree loves moderate lighting; if you periodically turn the pot, you will get a good crown, but there will be no harvest.
The dwarf coffee variety Nana grows up to 40 centimeters in height, so you don’t have to worry about its growth when placing it on a brighter windowsill.
The temperature in summer should not exceed 25 degrees; in winter, a temperature of 17 degrees must be observed.
The tree needs regular watering, and the water temperature should be warmer than the temperature in the room.
Arabica is fed in the off-season using solutions of mineral fertilizers.

To replant a tree without losing the plant itself, this procedure is carried out once every 2 years.

Important! When replanting, it is necessary to increase the size of the pot by 2 centimeters from the previous one.

A variety of Arabian coffee in Russia for growing from seeds can be purchased at a low cost. In Moscow you can find trusted sellers and breeders of plantings.

First transplant

If everything was done correctly, the first shoots will appear within the next 4-6 weeks. As soon as the plant reaches a height of 2-3 cm, it must be accustomed to room temperature. First you need to increase the ventilation time by 2-3 times.

Every day the ventilation time must be increased in order to reduce the time the plant stays in the greenhouse to zero within a month. In principle, by that time (2-2.5 months after planting) a small coffee tree with 3-5 fully developed leaves will have already been formed, which needs to be transplanted into its own individual pot.

The diameter of the first pot for a coffee tree should be at least 15 cm with a height of about 20-22 cm. Just like a pot for seedlings, it should be one third filled with drainage, which is expanded clay or small crushed stone. The soil level should be 1.5-2 cm below the height of the walls of the pot.

Coffee tree 3-4 months old in individual pots

It is best to choose clay or ceramics as the pot material, since additional air supply to the roots will not hurt, however, since the root system when grown at home is very close to the surface, this does not play a special role.

Step-by-step master class on sowing coffee seeds

It is better to use fresh seeds for sowing. If there is an opportunity to get seeds in fruits somewhere, then take advantage of it. If you buy seeds in a store, check the expiration date. The fresher the seeds, the greater the chance of seeing green sprouts after sowing.

1. Fresh seeds are released from the fruit shell (usually there are 2 seeds in the fruit).

2. Place the seeds in a cloth soaked with water in a warm place (+25 °C) for 12 hours.

3. Prepare a soil mixture of leaf soil, peat and coarse river sand in a ratio of 2:1:1. Then the seeds are laid flat side down on the soil and lightly sprinkled on top. The soil is moistened. Place the container with the sown seeds in the greenhouse. In order for the seeds to germinate, they must be kept at a temperature of at least +25...+27 °C. Periodically open the container and ventilate it. The soil must be constantly moist.

4. Seeds begin to germinate approximately 20–25 days after sowing. However, sprouts may appear after a couple of months. Within two to three weeks, the first pair of kidney-shaped leaves (cotyledons) begins to emerge from the seed coat. Quite often, the seed coat prevents the leaves from opening completely and must be carefully removed.

5. Real coffee leaves will appear only 2-3 months after germination. Remember, coffee loves humidity and heat. It is advisable to plant seedlings only when they have 3-4 pairs of true leaves. You can immediately plant each seed in a separate container. Mature plants are transplanted into a soil mixture: leaf soil, turf soil, peat, river sand, perlite in a ratio of 2:1.5:1:1:0.5.

Plant care

Conditions of detention

The living conditions of the coffee tree are quite simple: in summer the temperature should be between +22°C and +25°C, and in winter at least +15°C. Lowering the temperature is detrimental to the plant.

Coffee before transfer

However, it is also not worth exceeding temperatures above +25°C: in its natural habitat, coffee grows in the shade or partial shade of taller plants, therefore, despite the equatorial climate, it constantly remains in average temperatures. An increase in temperature also has a detrimental effect on the condition of the tree, as it leads to the evaporation of moisture from the leaves and their yellowing, followed by death.

Coffee trees in partial shade conditions

It is not recommended to place the coffee tree pot in direct sunlight. The light should be diffused.

On the other hand, you should not place the plant on eastern or western windows either - after all, in our climate the amount of sunlight is less than at the equator. Therefore, the ideal option would be to use partial shade or a diffuser (for example, in the form of curtains) on south-facing windows. As a rule, artificial light for coffee is not used during the active growing season.

The coffee must not be rearranged or moved. The only exception is when the tree is replanted. It should be remembered that even a slight rotation of the tree around its axis can lead to the cessation of flowering and the fall of leaves.

Flowering of a coffee tree grown from beans usually occurs in the 3-4th year of cultivation. By this time, the plants will already be quite tall and will have already been replanted at least twice. Sometimes it is recommended to provide flowering plants with direct sunlight for 1-2 hours a day.

Naturally, the pot with the plant remains in place; all obstacles between the tree and the Sun are simply removed.

Watering

Coffee loves moisture very much. Watering should be sufficient in both winter and summer. The criterion for the need for watering is the formation of a crust on the top layer of soil. Usually, in the summer, 1 watering every 2-3 days is sufficient. In winter, watering is reduced to once every 5-6 days. You should not over-water the soil - like most plants, coffee does not like stagnation of water in the roots.

Once a week it is recommended to spray the leaves of the coffee tree with a spray bottle.

This should be done in the morning or evening. Moisture should not be removed from the leaves after the procedure. Both watering and spraying are done with settled or boiled water at room temperature. This must be done to avoid any alkali getting into the plant and soil; After all, it should be remembered that the coffee plant is “sour”.

Feeding

The ideal fertilizer for a coffee tree is mineral liquid fertilizers for citrus fruits, sold in any flower shop. As a preventative measure, such fertilizers are applied every 15 days during the most active growth of green mass (from April to September). During flowering, it is recommended to double this dose.

The coffee tree must be fed regularly to ensure its full growing season and flowering.

You also need to remember that all crops that prefer acidic soils sooner or later “eat away” almost all the iron from the substrate in which they live. Therefore, it is necessary for plants to compensate for the lack of this element; To do this, once a year (for young plants - every six months) it is necessary to add iron preparations to the soil in the required dosage.

Subsequent transplants

The plant quickly selects all the necessary substances from the substrate, it has a high growth rate of the root system, so it requires annual replanting. After 3-4 years, replanting can be done every 2 or 3 years, annually only changing the top layer of the substrate.

Usually, transplantation is done into a pot with a diameter of 2-4 cm and a height of 1-3 cm greater than the previous one.

It is recommended to use soil for azaleas (or any other similar plants) for the first two transplants, and subsequent transplants to be done in soil prepared independently with the addition of additional raising agents (sphagnum moss).

Flowering and fruiting

Usually, before the first flowering, the coffee tree is pruned a little. This procedure has two goals: to shape the appearance of the plant and to stimulate it to flower. Typically, flowering occurs when the plant height is between 50 and 60 cm.

Coffee tree 4 years old

There are two methods of circumcision, each of which has its own goals. Either the growth cone is removed to ensure greater branching of the tree, or, conversely, the lowest branches are removed so that the plant accelerates its growth.

Traditionally, the first method is used more often when the plant’s growth exceeds 60 cm. The best time to carry out the procedure is early April, 1-2 weeks before the active growing season.

Approximately 1-2 weeks after pruning the plant, green tendrils appear in the axils of the leaves. These are the beginnings of future buds. Often their number is very large, from a few pieces to two dozen. It takes about a month for the buds to form, after which they bloom within 1-2 days.

Coffee tree flowers

Fruit ripening occurs within approximately six months. The beans remain green until approximately February of the next year, then turn white, and after that they take on the color of ripe fruit. It can be brown, red or yellow.

In the first season, the harvest will be small - about 70-100 fruits; each fruit contains 2 coffee beans.

Where to begin?

Naturally, the first thing you need to do is acquire Arabica in the form of a plant. And here there are three options - buy seeds and grow them yourself from scratch, buy a small sprout (or a large one, but more expensive) in a store, or take a cutting from a friend.

Each of these options has its advantages and what exactly to choose is a matter of individual preference. Growing coffee from seeds is more interesting, but also more difficult, and even a novice gardener can cope with cuttings.

Growing from seeds

Arabica seeds can be purchased at any specialty store. You can even try to grow a tree from green coffee beans, but this is quite difficult and unpredictable. The shell of coffee beans is very strong, and before planting it must be cut or kept in a special solution so that the sprouts can then germinate.

The seeds originally intended for planting, which are sold in the store, have already undergone the necessary processing, and the chance that they will later grow into a coffee tree is much higher.

The seeds should be sown in a mixture of peat and sand - this is one of the best combinations for such a plant. You can also add humus, leaf soil, charcoal - it won’t be superfluous. After planting, the seeds should be watered with warm water, covered with glass on top and placed on the sunny side, but without direct exposure to rays. The ideal temperature for growth is 20-30 degrees. Periodically, the future Arabica needs to be watered and a little growth stimulant can be added.

No further care will be required for now, all you have to do is wait. It will take a very long time for coffee seeds to germinate – this process usually takes up to a month. Therefore, you should be patient and not abandon the mini-plantation set up at home halfway. As a rule, a tree grown from a seed will begin to bear fruit in 3-4 years.

What to do with the cuttings

Everything is a little simpler if you managed to get a coffee stalk. In this case, you just need to put it in a jar with a small amount of water and wait until the roots appear. As soon as the root system becomes strong enough, the future tree can be planted in a pot.

Rooting requires a moist environment, so the pot with the plant must be covered with polyethylene or a transparent cap, having previously made holes in them for air exchange. Through the same holes, spray and moisten the leaves. Protect from sunlight, the light should be diffused, maintain the temperature at 25-27°C.

As soon as the tree takes root (the first two leaves appear), the cutting can be replanted and proceed to normal care. When replanting, do not remove all the peat from the roots, otherwise the plant may not tolerate the procedure well. Unlike a coffee tree from a seed, its flowering may already occur in the first year of life, and the bush will grow in width and bush without exposing the trunk.

Ready sprout

And the easiest option is to buy a coffee tree in a store. The main thing here is to choose a healthy sprout, with strong shiny leaves, and at home immediately transplant the plant into a new pot. In the first two to three weeks, the tree, like the cutting, will require increased care - in particular, more frequent fertilization, so that it can easily survive the stress of replanting.

If the stage of growing and rooting the flower was successful, further caring for the coffee tree at home should no longer be difficult. There are, of course, some peculiarities in maintaining the plant, but they are quite simple and do not require much effort or financial costs.

Propagation using cuttings

Cuttings must be made between the end of February and the beginning of March. On average, it takes about a month to root a cutting.

The advantages of cuttings over growing coffee from seeds are as follows:

rooting occurs in almost 100% of cases
unlike seed propagation, the plant inherits all the characteristics of the maternal
flowering and fruiting may occur in the same year (but, nevertheless, more often occurs the next)
the fruits of the first harvest are larger and there are more of them

Cuttings are made from branches from the middle of the crown of an already fruit-bearing tree. The cutting is cut at a distance of about 3 cm from the first pair of leaves. At a distance of 3-5 mm from the cut, several additional cuts are made on the cutting, necessary for better root formation.
The cutting is placed for several hours in a reteroauxin solution (a quarter of a tablet per 1-1.5 liters of water); A similar solution stimulates the formation of roots in the cuttings.
After which the cuttings are planted in a substrate (the same as that of the mother plant) to such a depth that the first leaves of the cutting touch the level of the substrate.
Next, the pot with the cutting is closed with a plastic bag, in which several holes with a diameter of 2-3 mm are made to provide air access.
Once a day, the cuttings are ventilated and watered by spraying the leaves with water at room temperature.
The plant should be in partial shade with a temperature between +22° - +25°C.

Cuttings with a formed root system

At the end of the root system formation procedure, it is necessary to transplant the cutting into its stationary pot. The transplant procedure is similar to that described earlier. After replanting, it is necessary to apply the usual fertilizing to ensure the growth of the green part of the plant.

Coffee tree propagation

Growing a coffee tree from seeds

Coffee tree from seeds at home.
Photo For the purpose of breeding coffee using seeds, only fresh, recently collected seeds are used. The older the grain, the less likely it is to sprout.

The sowing soil should be permeable and loose, for example, a mixture of leaf soil with river sand is suitable. Before sowing, it must be sterilized - held over steam from boiling water for about 10 minutes.

The seeds are laid flat on the surface of the soil without being buried; they rot in the ground. Then everything is watered with warm water and covered with polyethylene or a glass cap. Twice a week for 3 hours the greenhouse cap is removed to ventilate the soil. The most favorable germination temperature is 25 degrees. The first shoots can be expected no earlier than in 1.5-2 months. As soon as a few good leaves appear, the seedlings can be planted. Such a tree will bear fruit in 3-4 years.

Propagation of the coffee tree vegetatively

To breed coffee using this method, cuttings with two nodes are cut from last year's branches. They should first be soaked in a solution that stimulates growth, such as heteroauxin, for several hours. Prepared shoots are planted in a sand-peat mixture (1:1) with a depth of 3 cm. A drainage layer is required! Temperature conditions and watering are carried out in the same way as when growing seeds. For more successful rooting, it is recommended to organize bottom heating of the pot with cuttings.

After waiting for new leaves to appear from the bud, the sprouts can be planted. Coffee plants obtained in this way begin to bear fruit the very next year.

Tree diseases

Coffee is a fairly hardy plant and, with proper care, its immune system copes well with diseases and pests, however, cases are different, so you should not hope that everything will work out.

Well-growing domestic trees

The main problem for the coffee tree is excessive dryness of both the substrate and the air. Maintaining these parameters must be monitored first.

In any case, you need to be prepared for any whims, since it is not always possible to replicate the conditions that correspond to natural conditions for a coffee tree.

Coffee diseases include the following:

Brown rust

Caused by a fungus of the genus Himelia. Externally, the leaves are covered with large brown spots, which turn brown in the middle, spreading to the entire leaf. They are often difficult to notice because the lower part of the leaf is affected.

To prevent leaf rust, you should inspect the leaves daily from all sides and, if the first symptoms appear, spray the plant with fungicides. At the same time, the fungus can persist in the soil for a long time; it also needs to be treated with an antifungal agent. Sometimes the affected leaves have to be removed completely.

Coffee leaf with brown rust

If the disease comes again, it is necessary not only to treat the plant, but also to transplant it into another container.

spotting

Caused by a fungus of the genus Omphalia

Forms yellowness on the leaves, has a high spread rate and is more dangerous in impact than leaf rust. In addition to the leaves, it damages the stem and fruits. It helps to completely trim the affected areas and treat the remaining wood with Bordeaux mixture.

Gommoz

A disease caused by bacteria that results in leaf damage and a brown color. The leaves not only change color, but also become wrinkled and dry out quickly. After the leaves, the rest of the plant is affected.

To combat gommosis, it is necessary to remove the damaged areas, the rest is treated with copper sulfate. The plant must be moved to another place (even despite the danger of partial loss of fruits and leaves) and its conditions of maintenance must be reviewed.

Root rot

Despite the name, the symptoms are also determined by the foliage. At the same time it becomes gray.

The plant needs to be replanted as soon as possible, after first inspecting the root system and removing damaged areas

The remaining healthy root system is treated with a 0.2% solution of potassium permanganate before transplanting.

Problems in growing coffee and their solutions

Leaves begin to turn yellow or their tips dry out

The air in the room is too dry - the humidity needs to be increased. There are different ways: installing a humidifier, frequently spraying the plant, decorative bowls with wet pebbles, placing the plant on a tray with wet gravel or expanded clay, etc. Also, the leaves acquire a yellowish tint due to iron deficiency.

young coffee shoot

Dry blackish spots appear on coffee leaves

Most likely, the plant does not have enough moisture. The soil should be light, acidic, moisture- and breathable. The coffee should be watered and sprayed with warm water, generously in summer, immediately after the soil in the pot has dried, in winter – moderately, not immediately after the soil has dried, but a day or two later.

Soft dark brown spots appear on coffee leaves and they are expanding

Coffee does not tolerate not only dryness, but also waterlogging. If the spots occupy an increasingly larger area, then most likely the roots have begun to rot. In this case, the root system is inspected, and if the roots are rotten, they are cut back to healthy tissue (sometimes to half of all roots), treated with a fungicide and replanted in fresh soil. Then they put it in a microgreenhouse for resuscitation: there are few roots, the leaves continue to evaporate water, and it is necessary to create increased air humidity for the plant. If the roots are still slightly damaged, they are slightly shortened, the plant is replanted in fresh soil and cared for, paying special attention to watering: it should be slightly less than usual.

young coffee plant

The lower leaves of the coffee are turning yellow

If there is a gradual, slow yellowing of the lower leaves, one at a time, this is a natural aging process. Massive yellowing and falling of the lower leaves is a sign of plant starvation. About fertilizing, see below.

All the coffee leaves suddenly began to turn yellow

The plant experiences stress from sudden temperature changes. Coffee does not tolerate drafts.

The edges of the leaves are uneven and turn brown.

This may indicate a lack of mineral nutrition, particularly potassium. To prevent this from happening, coffee is fed with complex fertilizer with microelements 2 times a month. In winter, plants are not fertilized or fed once a month with solutions of lower concentration.

Varieties of coffee trees

Currently, several dozen different varieties of coffee trees are cultivated. In fact, they are hybrids of several species of coffee trees, obtained both naturally and artificially. They differ in size, taste and aroma of beans.

If the grower has a preference for the type of coffee variety consumed, you can choose and grow a tree of that same variety

Actually, the main division of coffee varieties is made precisely according to the varieties of these trees. Let's consider varieties of coffee trees that have a high probability of living relatively comfortably at home:

Variety Typica

Actually, that’s where it all started. Typica is the main Arabica variety and the first wild coffee tree in Africa to be cultivated by humans. Despite the relatively low yield, it is very popular among coffee producers because it has some of the most unpretentious growing conditions.

Branches of the Typica variety

The plant can be grown not only in the sun, but also in the shade. Therefore, the technique of growing it is called “shadow growing.” It was Typica, thanks to its unpretentiousness, that perfectly adapted to the conditions of Brazil, El Salvador, Yemen and even Vietnam.

The size of the Typica fruit reaches 13-14 mm, the size of the beans is 5-7 mm . On one branch of a bush (or tree), located in a horizontal rather than a vertical plane, there can be up to 200 grains. The height of the plant rarely exceeds 3.5 m, the yield is about 1 kg of finished coffee beans. Actually, Arabica coffee trees rarely reach such a height; usually, these are relatively short trees (often even bushes), about 50-90 cm in height.

At home, all this has to be divided into two: the actual maximum height of Typica coffee trees is about 2 m (well, the average is from 30 to 50 cm), the yield is 300-500 g of finished beans.

Ripe fruits of the Typica variety

Beginning gardeners are recommended to grow Typica as their first experience, since there are the fewest problems with it and there is a high probability of achieving not only a good growing season, but also flowering of the plant and its fruiting.

Variety Maragogyp

This is one of the Arabica varieties with particularly large grains. Sometimes it is called “Elephant variety”. The fruits of Maragojipa can reach 30 mm, and its grains - 15-20 mm. This does not affect the height of the plant in any way; it remains the same as that of classic Arabica (trees or bushes up to 1 m in height). This type of coffee has a pronounced chocolate flavor.

Branches of Maragojipa

The peculiarity of this variety is its non-African origin. It was obtained as a natural mutation of Typica, grown in Brazil. By some mysterious coincidence, the conditions in the area of the city of Maragogip turned out to be better for Arabica than those present in its homeland.

The variety has taken root well in other countries of South America; in addition, due to some climate characteristics of the area in which it is grown, the taste of its grains has characteristic differences:

Nicaragua – pronounced aroma and slight sourness
Mexico and Colombia - peanut flavor
Guatemala – weak chocolate taste, maximum similarity to classic Typica

In theory, Maragogipe has even greater adaptability than classic Arabica. It might be worth trying to start growing a coffee tree with it.

Bourbon

It is a variety of Arabica, developed in South America, but reintroduced to Africa. It has somewhat larger grains compared to the same Typica (by 1-1.5 mm). In addition, its taste is sweeter and more balanced.

Bourbon fruits are more variegated compared to Arabica: bright red or bright yellow. There are practically no visual differences in the form of the trees themselves. Bourbon is interesting because, firstly, it has greater survivability than many Arabica varieties, and secondly, it produces about a third more yield than Typica. However, it is sun-loving, and therefore requires appropriate growing conditions.

Ripe yellow Bourbon berries

Within this variety, there are about 3-4 varieties, differing in taste (sometimes very radical) and grain size. However, the agricultural technology of all representatives of Bourbon is absolutely the same. The plant has relatively good adaptability and can also be recommended as the first coffee tree to be grown.

Congo variety

Representative of the varieties of coffee trees from which Robusta is obtained. The Congolese coffee tree is truly a tree whose normal growth starts at two meters and can reach up to ten. The fruits are quite large (from 8 to 15 mm), up to tens of kilograms can be collected from one tree.

Congo coffee tree (robusta)

The trees from which Robusta is obtained are more hardy than those bearing Arabica. They cope well with drought and disease, and are resistant to most pests. However, due to the sourness present in it, the taste of robusta is not suitable for everyone. This explains why cuttings or cultivable Robusta beans are often difficult to obtain.
