The history of cherry plum Kuban comet

The variety Kuban comet was removed by G.V. Eryomina and S.N. Zabrodina at the Crimean Experimental Breeding Station of the All-Russian Research Institute of Plant Industry named after N.I. Vavilova. He was born thanks to the crossing of plum Skoroplodnaya and Cherry plum Pioneer. First, in 1977, this variety was taken for state tests. And after 10 years it was entered into the State Register of the North-West, Central Black Earth, North Caucasus and Lower Volga regions.

Characteristics of the tree and fruit, variety description, pollinator

Trees of this variety are stunted, as a rule, they are not higher than 3 meters and they are formed so that they look like a shrub. The trees have a gray color and short branches. Green leaves are glossy and not pubescent. Color buds may be small or medium in size with white petals.

The fruits are large. Their maximum weight is about 45 grams. They are rounded ovoid. The skin on the fruit, although thin, but dense, also has a small wax coating. When the fruits begin to ripen, they first become yellow-red in color, which gradually turns into burgundy. Bones may be small or medium. The flesh has a yellow color and a fibrous texture. It is juicy, with a good ratio of sugar and acidity, so it has a sweet-sour taste that resembles apricot.

Over-grown fruits do not crumble for a long time, and also have good transportability. If they did not get the desired burgundy color on the tree, then they will get it in the store. You can keep them in the fridge for about 25 days.

The variety of this tree is frost-resistant, can tolerate frosts up to 30 degrees. But the frost resistance of the buds of flowers is below average, but even when they are very cold, the harvest will be good anyway. Flowers also easily survive the spring frosts.

This tree is especially undemanding to the soil and can perfectly adapt in different regions from the Transcaucasus to the Non-Black Earth Region and the Southern Urals, to the south, to Primorye. Still, clay and loamy soils do not quite fit her.

Alycha tree Kuban comet

Pollinator for the Kuban comet is not needed, since This variety has a rare quality of self-fertility for cherry plum., but in order to improve fertility next to them it will be useful to plant other varieties of cherry plum or Chinese plum. For example, such as Mara, Traveler, Red Ball and others.

Terms of ripening and harvesting

Saplings bear fruit very early, 2 or 3 years after planting.. They begin to bloom in late April, and in mid-July - early August, fruits are already appearing.

Trees bear much fruit every year. For example, about 10 kg can be collected from a small tree, and about 50 kg from a large one.

Advantages and disadvantages

The Kuban comet variety has its advantages, here are some of them:

  • fruits are large,
  • high yield,
  • precociousness
  • frost resistance
  • partial self-fertility
  • resistant to disease
  • if the fruits perespeyat, they still do not fall for a long time and do not crack,
  • fruits are delicious.

But the variety is not perfect, it also has its drawbacks:

  • the bone is very badly separated from the pulp,
  • to ensure the large size of the fruit, they need to be cut off, leaving them more space next to each other,
  • fruits ripen unevenly.

Landing rules

Trees of this variety are planted in early spring or early autumn.. First you need to choose the right seedlings. It is best to select them with a closed root system.

Cherry plum saplings Kuban comet

A good seedling has the following indicators:

  • height from 1 to 1.20 meters
  • the root consists of many small roots with good ramification,
  • there are swollen buds,
  • bark should not be damaged, stains and traces of pests
  • it is necessary that the cut was wet, yellow-green.

When the seedling is selected, are determined with the landing site.

The best option would be a plot on the south side. Kuban comet does not like shadow, drafts and strong wind. Perfectly put her where she will have a shelter in the form of a wall.

Alycha will like sandy soil with low acidity. It is reasonable to mix the planting soil with humus (12 kg), superphosphate (250 grams) and potassium sulphide (50 grams). The pit should be dug up to 80x80x80 cm.

Landing steps:

  • In the hole poured a bit of land in the form of a small hill.
  • Insert a wooden stick.
  • The root neck is placed 6 cm higher from the ground.
  • Rammed the ground.
  • A sapling is tied to a fixed stick.
  • Watered with 2 or 3 buckets of water.
  • At the end of the top pour chips.

In the case of planting several trees, you need to stick between them a three-meter distance.

Care of the Kuban comet

This variety loves moisture, because it must be additionally watered during the growing season. Do it in June, July and September. One tree requires up to 40 liters of water. After watering, be sure to pour chips.

The tree is cut or shortened each year by cuttings and thinning the crown. Most often they make a bottomless or bowl shape.

The main pruning done in the spring. During this period, a crown is formed and frozen and damaged branches are cut off. In the autumn period, dry, sagging and diseased branches are sawn off. Summer pruning is carried out with great need, while cutting off the young shoots that grow inside the crown.

Scheme of pruning cherry plum Kuban comet

Kuban comet must be fertilized annually. The only exception is the first year after planting a tree, if it was planted in fueled soil.

Fertilizer is as follows:

  • in the autumn pour out the humus with the calculation of half a bucket on 1 square meter,
  • after the tree blossoms, bring 40 grams of urea per 1 square meter,
  • after fruiting fertilized with potassium sulfate, 30 grams per 1 square meter.

A young tree, in the first years of its life, must be covered for the winter, for example, with sacking.

Sheltering with polyethylene is prohibited. It is not necessary to warm the Kuban comet with hay or straw, because rodents can live there.

Diseases and pests

The Kuban comet is resistant to diseases and if it is properly looked after and processed in time, then there will be no trouble. The problem is that it pests and diseases from neighboring trees. This variety affects the same kinds of diseases as a regular plum.:

  • gray rot
  • brown spot,
  • rust,
  • gum treatment.

Gray rot

Gray rot is caused by Botrytis fungus. The place of birth of the infection is sclerotia and conidia, which are found in the soil and plant residues.. In the case when the disease affects the Kuban comet, branches begin to wither and a brown tinge appears on them, and small gray growths appear on the bark and fruits. The fruits begin to rot.

Gray rot (moniliosis) cherry plum Kuban comet

To destroy the gray rot, trees before blooming are sprayed with copper sulfate and Nitrofen, which need to be used for processing wood and soil. And also after flowering, Captan and Kuprozan are used.

To prevent the disease, it is necessary to spray trees with such preparations in early spring:

  • 1% bordovskaya fluid
  • hand boron for affected fruit,
  • whitewash.

Brown spot

Brown spotting, or it is also called leaf mold, is also a fungal disease. Sometimes it can kill about 50% of the crop.. This disease is characterized by the appearance of brown spots with dark rims on the leaves, which have a black dot in the center. Over time, the leaves wither and fall.

Trees against brown mold need to be treated with 1% bordovskiy solution as soon as the buds begin to bloom, it will also have copper oxide 2 to 3 weeks after flowering.

Preventive actions that will help prevent the disease are as follows:

  • need to remove damaged branches,
  • before the buds bloom, you need to spray the tree and the soil with 1% of the blue vitriol.

Rust

Another type of fungal disease is rust. When this disease on the leaves appear rusty spots, which eventually turn into dark pads. Rust wood is treated in the second decade of July. You can use Aktofit. They are sprayed with trees 2 times with an interval of 2-3 weeks.

To prevent the Kuban comet from being attacked by rust, preventive measures should be taken:

  • 3% carbamide solution sprayed with wood in early spring,
  • when the leaves fall, it is raked and burned.

Comedication

It is dangerous because it can slow down or stop the growth of a tree, and eventually even destroy it.

Kametdeteka cherry plum Kuban comet

Thinking is not a fungal disease. The reasons for its occurrence may be mass. Here are the most common ones.:

  • severe winter conditions, because of which the tree has frozen,
  • received burns from the sun,
  • improper pruning, because of which the tree was damaged,
  • mechanical bark damage,
  • over sized fertilizer application and watering
  • tree infestation bark beetle.

When you look at the tree, you can see gum (protrusions of amber resin) on its branches, which indicates the damage of the tree by this disease. It is possible to process the Kuban comet from this disease throughout the entire season.. After pruning, be sure to put petrolatum on slices. And also cut off the growths of gum. The place where they were was disinfected with 1% solution of copper sulphate and covered with a non-black putty.

  • fruit sap,
  • western marsh bark beetle,
  • down silkworm,
  • moth.

Fruit Saplings

In the case when there is comediness on the tree, and horizontal passages with a diameter of 1 to 2 millimeters can be seen on the branches and the trunk, then a fruit sap settled on the tree.

Fruit sapwood - a very common pest of cherry plum

Prior to laying eggs, females eat tissue at the base of the kidneys. When the larvae appear, they absorb the bark and roots. To destroy these pests the tree is sprayed at the end of flowering.. The treatment is carried out 2 times with an interval of 14 days.
