How does an avocado grow?

Over the past few decades, many exotic plants have entered the life of domestic people. However, even in relation to the most common of them, our knowledge remains very scarce and limited.

At the same time, an accurate idea of, for example, an avocado is valuable not only for gardeners and gardeners who love experiments. This knowledge is also needed by ordinary consumers.

What it is?

Avocado is a fruit that is grown in tropical and subtropical regions. The main plantations of this crop are located in Indonesia.

Russian climatic conditions do not allow industrial cultivation of avocados, so all its supplies are carried out from abroad and cost a lot of money.

A few decades ago, this fruit was allegorically called the "alligator pear". This name was given because of the characteristic rough and dark green skin of the fruit, as well as a shape similar to that of a pear.

Avocado grows on evergreen trees and has a large seed inside. However, chemical analysis shows that this fruit is closer to vegetables, since there is very little sugar in the pulp, and the energy value is quite high. The taste is rather bland and not delightful. Such properties allow the use of avocados as a component in various salads and other mixed dishes.

Many valuable trace elements and organic substances are noted in the composition of fruits:

  • calcium;
  • iron;
  • phosphorus;
  • cellulose;
  • various amino acids.

The dietary properties of this culture are combined with its ability to have a preventive effect in relation to many common diseases (primarily cardiovascular diseases and oncological disorders). According to doctors, eating avocados is very useful for digestive disorders.

Also, the fruit improves the supply of water to the body, but for this reason it is contraindicated for anyone who suffers from water-salt balance disorders. It is undesirable to use it for allergy sufferers: there is some specific intolerance.

Origin

Avocado grows on a tall (up to 20 meters) tree. Botanists consider this culture close to the noble laurel, which was abundantly cultivated by the ancient Greeks. For the first time, avocado culture began to be massively cultivated in Israel, so this country can be considered his second home.

Initially, it comes from North America, more precisely, from the territory of modern Mexico. Both the Aztecs and our contemporaries living there do not neglect this culture. It has become an integral part of Caribbean cuisine.

The first description of the avocado was given by the Spanish invaders back in 1526. The colonizers compared the fruit to a peeled chestnut. According to the results of archaeological excavations, it was possible to establish that the avocado was known as early as the 8th century AD. If we start from ancient drawings, then it can be considered proven that this fruit grew 7 - 10 thousand years ago in the gardens of the distant ancestors of the Aztecs. It was possible to find out that even then the seeds of cultivated plants were larger than in the wild.

Linguists believe that the word "avocado" comes from the Aztec language Nahuatl, the literal translation is "egg tree".Apparently, it was precisely such associations that arose among the ancient Indians.

The main exports of avocados are now led by such countries as: the USA, Chile, Dominican Republic and Indonesia. The ancestral home of the avocado, Mexico, adjoins them.

What does a tree look like?

In nature, the avocado (or American Persea) is the only edible member of its botanical genus, which is part of the laurel family.

The height of an adult tree reaches 6 meters, it has a wide crown. Despite the fact that the plant is among the evergreen species, there are varieties that drop leaves (albeit for a very short time). The diameter of the trunk after the end of the growth period varies from 0.3 m to 0.6 m.

The trunks are straight at the bottom, branching closer to the top. The foliage is sharp, elliptical in shape. From above it is dark green in color, and the lower edge is whitish. You can recognize Mexican varieties by their characteristic anise aroma. The avocado leaf is very rich in essential oils, however, they also contain substances harmful to human health.

The flowers are small, inconspicuous in appearance. The predominant color is pale green or yellow-green. The inflorescence is of the panicle type. Most flowers have 1 pistil with a pair of cups for 9 stamens. Flowering occurs profusely, however, complicated pollination leads to the fact that only 4% of the flowers form an ovary.

During the flowering season, the opening occurs twice. Avocados can be cultivated in several varieties at once. Avocado fruit is considered a type of pear-shaped drupes. The length can be up to 330 mm and the width up to 150 mm. Weight varies in a fairly wide range: from 50 g to 1.8 kg.

You can find avocados with four skin tones:

  • dark green;
  • yellow-green;
  • red-violet;
  • dark purple.

The edible pulp begins just under the skin. Following it is a single seed growing in the form of a circle, egg or cone. If pollination has occurred poorly (or under the influence of other reasons), some of the berries may not contain seeds.

The root system of an unusual plant allows it to grow successfully on a wide variety of soil types. Good results are achieved on red clay and sand, limestone and loam of volcanic origin.

Good drainage is essential for successful avocado cultivation. Excessive moisture, even if it does not reach the temporary bay, is contraindicated. There should be at least 9 meters of soil between the surface and the water horizon.

The fruits ripen in 0.5 - 1.5 years (the exact period is determined by the climatic conditions of the growing region and the variety). Final ripening occurs only after detachment from the stalk (for 7-14 days at room temperature).

Growth features

The plant has a number of growth characteristics that must be considered.

Under what conditions?

Avocado grows in tropical and subtropical climates, but there are certain differences between his groups.

  • So, mexican selection of varieties most resistant to bad weather. It will be able to withstand the short-term effect of frost from 4 to 6 degrees. Wherever oranges ripen, avocado plants from Mexico will also give a good harvest.
  • West Indian cultivar group dies even from the slightest frost. There is simply no chance to grow them in the Russian Federation (outside of a year-round heated greenhouse).

Avocado tolerates shade well, but at the same time, all development goes into the crown.Fruiting is possible only in open areas of land with intense insolation. Be sure to need loose soil with deep drainage, but the acidity or alkalinity of the earth is of no particular importance for growth.

A prerequisite for the successful cultivation of avocados is the loosening of the root ball for effective aeration. The American "guest" feels bad if strong winds blow. In dry air, the pollination process is disrupted and the crop is reduced. Perseus should not be overfed with fertilizers.

The less mineral salts in the water that the tree is watered with, the higher the yield.

In what countries?

Traditional sites for the cultivation of avocados: Southeast Asia, Australia, Peru, Philippines, countries of Central and South America. In Malaysia and Thailand, an exotic tree grows easily and confidently. In Russia, it can be grown exclusively on the Black Sea coast (only representatives of the Mexican group of varieties are suitable for cultivation). Abkhazian conditions are also favorable: fruits with a high concentration of oils are obtained here.

The choice between directly soil and container landing methods is determined by the climate of a particular region. If in winter there is at least a slight risk of frost of -7 degrees or more, then you need to use containers. In the cold season, it is necessary to transfer the plant to greenhouses or heated rooms. Therefore, you have to use dwarf varieties or systematically prune trees. The high growth rate of avocados necessitates regular replanting.

In the later stages of development, the largest pot no longer copes with its task. You need a barrel or some other large container.It is recommended to use containers on wheels, which are easier to move.

Note: Avocado branches need a special support. It will help to avoid deformation of the young shoots of the plant. Watering is required only against the background of drought. When sufficient natural precipitation falls, there is no need for special soil moisture. The dryness of the earth is controlled at a depth of up to 0.25 m. Dry and crumbling earth when pricked with a stick should be watered immediately.

Top dressing is carried out once a quarter, for this they use both mineral and complex fertilizers, and special mixtures. Mature trees require the introduction of nitrogen at the end of winter and in the first days of summer, as well as the annual addition of trace elements.

If in nature the variety forms a crown in the shape of a cone, then its pruning is aimed at rounding the contour. Mature plants are not subject to pruning.

Before the onset of frost, each fruit should be removed (regardless of the degree of maturity). The thing is that when cooled, the fruits turn black and become unsuitable for food. Young avocados should be covered from frost with special covering materials. If the plant is grown in a greenhouse, then you should take care of additional heating and insulation of the trunks with foam rubber.

For amateur gardeners, growing avocados with a seed will be the easiest. You can not buy germinated seeds in a special store, since embryos from purchased fruits also give good results. You just need to make sure that the avocado is ripe, and you should use the seed for planting immediately. It is recommended to plant the stone immediately into the ground, as this culture transplant is tolerated without much enthusiasm.

Season

Avocado flowering occurs almost all year round (and on any continent of the globe).But, according to connoisseurs, the most delicious fruits ripen from the beginning of August to the end of April.

Californian avocados ship throughout the year, while Florida avocados only ship from fall to spring. Israeli fruit is shipped from late autumn to early winter. It was then that the bulk of avocados appear on Russian store shelves.

For commercial shipment, only solid fruits are selected. And to check the maturity of the fruit by the consumer, agronomists recommend focusing on the state of the stalk: in a ripe fruit, it disappears or becomes darker.

The bone is not suitable for human consumption, it is not only tasteless, but can also be dangerous to health.
