Plum-cherry hybrids: features, varietal assortment and growing secrets
The practice of crossing and breeding new varieties is quite popular among amateurs and professionals who specialize in growing vegetables and fruits. Sometimes the combination of two crops in horticulture brings positive results. Among the most striking examples, it is worth highlighting plum-cherry hybrids.
Description and varieties
Fruit stone fruit crops are present in any summer cottage or in the courtyard of a private residential building. Most often, this group is represented by cherries, sweet cherries and plums, known to everyone. However, real experimental gardeners are in constant search for new species and varieties to obtain a high yield of delicious and unusual berries and fruits.
The work of breeders is conducive to the search for new hybrid crops, pleasing with more advanced species. The plum-cherry hybrid will be an interesting and appetizing addition to any garden, and due to its characteristics, care and planting will not differ much from growing the usual types of plum and cherry trees on the site.
Crossed types of stone fruit crops have a number of common features, it was this observation that became the impetus for an experiment to combine them. The result of the work was to obtain a hardy and productive variety. For the first time, crossed SVG appeared in the USA; American cherries and Japanese plums were used to obtain it.The latter endowed the fruit with a rather large size and unusual taste; from the cherry, the hybrid inherited resistance to external environmental factors and ease of care.
Russian scientists are still developing new varieties of stone fruit crops, the main goal of these experiments is to obtain a variety with high resistance to harsh climatic conditions and a high yield of berries.
The plum-cherry hybrid is an early-growing crop capable of producing a crop in the second year after planting. This feature characterizes the SVG from the positive side. Plants grow on average up to 150 cm, and look like sprawling shrubs. However, the height of the culture is very dependent on belonging to a particular variety.
The small size of the plants allows you to plant a crop even in areas that differ in a rather modest area. They do not create an extra shadow for other trees, in addition, a height of up to 1.5 meters makes it easier to pick berries.
Depending on the variety, the plum-cherry hybrid has a varied crown. As for the root system, the plant has branched and large roots, thanks to which it tolerates both frost and drought well.
The leaves resemble a plum leaf, grow alternately and have a rich green color. The flowering of the culture begins a little later than the mother plant varieties used to breed the hybrid. Flowers have a pleasant aroma and white color.
As for the yield, the branches of the plant during the period of fruit ripening are simply strewn with berries, due to which the shoots of the culture quite often sag from gravity. To avoid breaking branches, gardeners equip a special support around the bush. Ripe fruits can be harvested in August - September. The shape and size of the fruit depends on the variety.
Berries are used for canning, freezing and fresh consumption.
However, when planting SVG, it should be borne in mind that in order to obtain a crop in the garden, it is necessary to plant several varieties of the crop or mother plants, since the hybrid is self-fertile.
The plant in question is very popular, therefore it is presented in a wide variety of varieties. The most popular plant varieties are presented below.
- "Omsk night"- a stunted plant with large black berries, which ripen in August. The mass of one fruit is about 15 grams, the culture stands out for its high yield, so about 40 kilograms of berries can be obtained from one bush.
- "Beta", as a rule, rarely grows more than 1.5 meters in height, the berries are red in color with a pulp inside of a similar color. According to fans of this variety, the berry is similar in taste to cherries.
- "Opata" - the SVG variety, which stands out from the background of other varieties in height, the average tree can reach two meters in size. The crown of the hybrid is rounded, the fruit grows in the form of an oval red-brown color with yellow flesh.
- "Pyramidal" variety represented by small plants that are resistant to frost. The fruits are yellowish-light green with a slight sourness. Due to their pyramidal crown, such bushes are often used for decorative purposes.
- "Maynor" also refers to dwarf shrubs, in appearance it resembles a ball. The fruits are dark purple and round.
- plant varieties "Compass" can grow up to 2 meters, the berries have a brownish tint, they taste quite sweet.
- "Sapalta" has a rounded crown, the fruits are purple in color with lilac flesh.
- Variety fruits "Hiawatha" distinguished by their size, they are egg-shaped and purple in color. There is an unobtrusive sourness in the taste.
- "Gem" refers to medium-sized trees, since its height can exceed 2 meters. The flowering of the variety comes later than all, the culture is resistant to frost. The fruit inside has a yellow tint.
reproduction
It is quite possible to get SVG yourself, for this it is worth studying the options for plant propagation, as well as having a healthy stone fruit tree on the site. Since the hybrid is artificially bred, it is unlikely that it will be possible to obtain a similar variety by conventional breeding with the help of fruit seeds, but some gardeners often use this option.
The most common methods for growing these types of plants are the following:
- graft;
- cuttings;
- horizontal outlets.
Grafting is the most common way to propagate fruit crops. Grafted seedlings begin to bear fruit faster, in addition, this method is considered the fastest option for breeding a hybrid variety.
It is best to propagate the culture by grafting on the Bessey sand cherry or on SVG seedlings.
Since the plum-cherry hybrid quite rarely forms root shoots that could be used to grow a young plant, cuttings are cut from a young shoot to breed a culture. Usually, the preparation of the material takes place at the end of spring, during the period of active growth of the crop.Healthy shoots are cut into cuttings about 30 centimeters long, after which they are all placed together in a solution that promotes the formation of a root system.
The material is rooted in a well-heated greenhouse in a container with a special mixture, where sand and peat act as the main components. In autumn, they are sent for storage in a dark place, most often in a barn, where a special recess is created, covered with moss and sawdust. The plant will be ready for planting only in two years.
Due to the small height of plum-berry hybrids, many gardeners prefer to propagate the culture by layering. Works are carried out at the end of the spring period during the growth of young shoots on the bushes.
On an adult plant, the material closest to the soil is selected and bent to the ground, to the previously dug groove, the central part of the branch is sprinkled with soil. In order for the shoot not to turn to its usual position, it is fixed with a wire.
Layering care is carried out using the same technology as for an adult hybrid. After the shoot is well rooted, it is disconnected from an adult bush and transplanted to a permanent place in the garden.
Reproduction with the help of a bone, according to gardeners, can give a completely unexpected result when working with hybrids. In some cases, this method still allows you to bring out a culture, but its characteristics will not be at the highest level.
Landing and care
As a rule, hybrids are planted in a plot of two, while trying to choose plants belonging to different varieties.In order to protect the stone fruit culture from waterlogging or freezing, young plants are planted in specially equipped mounds, in addition, drainage is used, as well as a heat-insulating pillow. The introduction of organic fertilizers into the soil is mandatory.
When choosing a site for planting, it is best to stop on the south side of the site near a residential or outbuilding. The north side should be protected from the wind by planting tall shrubs, they will help protect the crop from the cold wind in winter. Coniferous trees can be used as "neighbors".
In order for the young plant to take root as quickly as possible after planting, it is planted only in warm ground, and when planted, it is watered with warm water.
Because hybrids are self-sterile, they need a nearby plant to pollinate. Its role can be played not only by hybrids, but also by ordinary varieties of plums or cherries.
In addition to the specific planting of SVG seedlings, the care of the plant as a whole is carried out as for an ordinary plum tree. It needs watering only in extreme cases, when the plant received less natural moisture due to the climate.
To reduce the risk of plant diseases, it is treated with special compounds, and it is fed with nutrient complexes. As a fertilizer, it is recommended to use nitrogen, wood ash, potassium and fluorine. Usually, elements are introduced into the soil before the arrival of frost in order to additionally nourish the crop before the onset of winter.
In addition to the standard measures regarding the care of the hybrid, the bushes must be regularly thinned out, as well as the unfruitful branches should be removed.
If it was not possible to plant the crop in the ground before the onset of cold weather, then it can be temporarily left in the basement in a container with earth, or it can be dug together with a container in the garden until the onset of a favorable period.
Diseases and pests
The greatest danger to SVG, as well as to its mother cultures, is moniliosis. The signs of the disease are as follows: the foliage looks burnt, the flowers dry, and the disease manifests itself visually on the shoots last.
If such symptoms are found on the culture, the “sick” parts must be cut off and burned. For the purpose of prevention, the plant is treated with Bordeaux liquid, in addition, copper oxychloride is used for these purposes.
To protect the culture from small rodents, the trunk of a young bush must be covered with coniferous branches or non-woven material.
In the course of growing a crop, caring for and protecting against diseases and all kinds of pests, one should not forget the main thing - that the plant is still different from its "parents", since, in fact, it is an independent culture that has specific characteristics and features.
gardening tips
To reduce the risk of plant death due to improper care and maintenance of plum-cherry hybrids. It is worth adhering to the recommendations given by experienced gardeners who have been breeding such stone fruit crops for several years.
It is worth dwelling on some of them in detail.
- It is very important to choose the right place for planting a plant in your area. To do this, first of all, the level of groundwater occurrence is taken into account.Taking into account their location and depth, they stop at one of two options: a high level requires planting a plant on an artificial hill that will have good drainage; with normal water occurrence, no special conditions for planting are required.
- In order for the plants to be as free as possible and they could fully develop when planning the planting of trees, it should be borne in mind that the optimal distance between hybrids should be at least two meters.
- With increased acidity of the soil, before planting the crop, it is worth additionally fertilizing the soil with dolomite flour. Clay soil needs the addition of river sand and humus. The future growth and productivity of the plant directly depends on the quality of the soil.
- As for fertilizers, it is not necessary to feed a young seedling with nitrogen supplements, since the element will provoke the active development of shoots, which will adversely affect frost resistance. As for phosphorus and potassium, these trace elements have a positive effect on the growth of a strong crop and provide greater yields in the future.
- Unfortunately, in addition to the positive qualities, the hybrids also inherited negative properties from the mother plants. This applies to the tendency to fungal diseases.
Therefore, preventive measures and timely treatment of crops are vital, especially for a disease such as moniliosis.
