Columnar apricot: features of the type, varieties and cultivation rules
The columnar shape of garden trees is a real achievement of breeders. They got this name for their resemblance to a column, so it would be more correct to call the plants "columnar". But the spelling of this word as an agrotechnical term with just one letter “n” has become more widespread.
Mass cultivation of varietal apricot in central Russia until recently was considered impossible. Therefore, this southern columnar tree in the latitudes of the Moscow region can be called a double achievement of selection.
Plant characteristic
Description
At first glance, a columnar tree is a single trunk, on which fruits grow without branches. But if you take a closer look, you can make sure that there are still branches, they just have a small length (literally 15–20 cm). First, beautiful white or pink apricot flowers develop on them, and then bright, slightly pubescent, sweet fruits, which are large berries with seeds inside. The spiky leaves may be slightly elongated or heart-shaped. The trunk of a columnar apricot can reach a height of 2, and in a warm climate - even 3 meters.
Pros and cons
The columnar form has undeniable advantages.
- compactness - suitable for small plots, requires little space for growing, does not create shade for other plants.
- Short development time - already in the third year, the planted stalk begins to bear fruit.
- Ease of harvesting - compact shape without long branches allows you to quickly collect all the fruits.
- decorative - a trunk strewn with large flowers or bright fruits looks very beautiful, especially since the leaves appear later than the flowers.
There are also disadvantages, but they are minor.
- The need for shaping pruning - you need to leave branches no longer than 20 cm, otherwise the yield will deteriorate.
- Frequent tree updates - a columnar plant can grow and bear fruit for up to 15 years, then the yield drops, and the tree must be replaced.
Varietal assortment
Since the columnar apricot appeared relatively recently in the middle latitudes, the assortment is not very rich, but there are species that have already become widespread. Consider the best varieties that are suitable for cultivation in the suburbs.
"Star"
It has important qualities for the middle lane - frost resistance and average ripening time. Withstands winter temperatures down to -30°C. The fruits ripen in mid-August. The variety is productive and large-fruited. Golden yellow apricots can grow up to 80-100 grams in weight, have a pleasant taste and aroma.
"Star" is a self-fertile variety, pollinators are not required for it. With proper care, fruiting can begin as early as the second year after planting. Resistant to diseases, rarely affected by pests.
"Prince March"
One of the most popular varieties of columnar apricots. Winter-hardy, able to withstand even 35-degree frost. Mid-season, the harvest can be harvested in the second half of August.
The tree of this variety is very compact, grows no higher than 2 meters, which is very convenient when caring for and picking fruits. The variety is self-pollinating, has a stable good yield. Orange with a side toasted on the illuminated side, the fruits grow, as a rule, up to 40-60 grams. Apricots are very juicy, have a pleasant sweet and sour taste.
Fruiting usually begins in the third year after planting, but with careful care it is possible to get a crop in the second year. The variety is reliable, resistant to diseases and pests.
Agricultural technology
Requirements
Apricot as a southern crop needs good lighting, so the place for growing should not be shaded. You also need to take care of the wind protection. A wall of a house or a fence can serve as a barrier to the elements, but the distance to them must be at least 1.5 m.
It is better to choose areas with a flat terrain, not too low and not very elevated, without closely standing groundwater. Apricot prefers soils with a neutral or slightly alkaline reaction, therefore, in acidified areas, lime, dolomite or other deoxidizers will need to be added to the ground. It is also necessary to provide drainage. The soil should be fairly light, loose and nutritious.
Landing and care
In the latitudes of the Moscow region, it is better to plant an unusual apricot in the ground in early spring. Autumn planting can only be recommended in warmer southern regions.
Pits with a nutrient substrate should be prepared in advance so that the soil has time to settle before planting, and not with the seedling. This is dangerous because the place of vaccination will go underground. The required depth of the pit is about 0.7 m. At the bottom, you need to create a drainage layer, for example, from small gravel.It is best to fill the pit with a mixture of 2 parts of rotted manure, 2 parts of earth and 1 part of sand for loosening and deoxidation. You can use forest land, but not from under coniferous plants, as it will be acidic, and such soils are not suitable for apricots.
If you plan to plant several plants, it is recommended to keep a distance of at least 5 meters between them. Despite the fact that the trees themselves are quite compact, they form a rather powerful root system, which needs to be provided with the necessary space for development.
Before planting in the ground, it is advisable to soak the roots of the plant for 1.5–2 hours in a solution of complex fertilizer to improve survival. Then, holding the trunk in a vertical position, the root system is placed in a hole, carefully covered with earth to the place of inoculation and the soil is compacted so that voids do not form.
The main care is watering and fertilizing. The soil should be kept sufficiently moist, but not flooded, as this can cause root rot. The lack of water does not affect the crop in the best way - the fruits will be tied small and in small quantities. Therefore, if the summer turns out to be dry, it will be necessary to water at least 1 time in 2 weeks. It is most convenient to do this in specially dug shallow grooves. For one watering, each plant needs about 10 liters of water heated in the sun.
The optimal number of dressings is 3 per season. The first is best done after planting or, if it is not a seedling, but an adult plant, in early spring, before flowering. The second - about 14 days after the appearance of the leaves or during fruit set. And in 2 weeks - the third.
The columnar apricot responds well to organic fertilizers.For example, you can pour it with a solution of bird droppings (1: 15). Complex mineral fertilizers with nitrogen, phosphorus and potassium are also useful. They must be applied following the instructions on the package.
Also, in the first year after planting, it is imperative to remove all the color, preventing the formation of ovaries. This will save the tree strength for the harvest of future years.
Despite the fact that the declared frost resistance of the columnar apricot completely allows it to survive the Russian winter, surprises in the form of a small snow cover or very severe frost with sharp thaws are not excluded. Therefore, it is better to cover the plants, for example, with spruce branches or burlap, tying them with a rope that is not too tight. If another covering material is used, it must be breathable.
Disease protection
The columnar apricot can be affected by moniliosis, and kleasterosporiosis is also dangerous for it. Treatment is best done as a preventive measure, without waiting for signs of disease to appear. Good results are obtained by the use of copper sulphate or Bordeaux mixture. If affected leaves or branches do appear, they must be cut and destroyed as soon as possible.
Pests that can harm trees and crops are aphids and codling moths. In the fight against them, solutions are used that contain copper in their composition, or complex purchased products, for example, Holister.
pruning
To properly form a columnar tree, pruning must be taken very carefully. This process is best done in early spring before flowering. The trunk should be shortened to 1 meter. The lower branches, which are up to a trunk height of 0.5 m, must be removed. Lateral branches must be cut to a length of about 20 cm, making sure that they have at least 3 buds.In mature plants, old non-fruiting branches should be removed.
gardening tips
It can be concluded that caring for a columnar apricot is no more difficult than caring for any other fruit tree. Russian gardeners have already fallen in love with it for its convenience in growing, the taste of juicy fruits and good yields. Moreover, many techniques are applicable to the apricot, which are used in the care of crops that have long been “registered” in the gardens of the middle lane.
For example, mulching can be used to retain moisture in the soil. In pest control, whitewashing the trunk is effective, which has long been used on apple trees and other trees. Yes, and preparations against apple-tree parasites are suitable for apricots.
Reviews of gardeners say that the columnar apricot is no longer a curiosity for them, and in response to care and attention, it pleases with beautiful flowering and a good harvest.
