Plum Renklod kolkhoz: description of the variety, features of planting and care

The plum variety Renklod kolkhoz would have been bred by IV Michurin at the end of the 19th century and since then has not lost its popularity among gardeners. This is a hybrid of thorny plum and green Renklode. The date of birth of the masterpiece of selection can be called 1899. This year, ten years after planting the tree, the first fruits of this variety were obtained. Many years later, in 1947, the hybrid was sent for testing in the northwestern and central regions of the country. It is possible to grow this stone plum using the plant as a rootstock for other varieties. Plum trees not only bear tasty and nutritious fruits, but also serve to decorate the garden. In the spring, they will be covered with wonderful snow-white flowers, filling the space around them with a fragrance.

Description of the variety

Plum Renklode kolkhoz is a representative of the home plum group. Fruit ripening period is early or medium. Plum Renklode collective farm bears fruit on bouquet branches. The size of these trees is small: only 3 meters high. They have a medium-leafy and spreading crown of a rounded shape, smooth silvery bark, straight shoots of medium thickness and a reddish hue. There are few lentils, they are small in size. Leaves are oval, medium, light green, wavy along the edge. Petioles are pigmented. The flowers are white, small in size.

Differences between Renklode and other plums, its characteristics

The variety has been known since the 16th century. He came to us from the expanses of South-Western Europe, or rather, from France, where he was named after Claudine, daughter of King Louis XII. At one time, she became queen, being the wife of her late father's successor. The spouse said that Claudine's kind character and cute appearance are as good as the taste of the fruit of the plant derived from the Verdicchio plum. It was decided to name the variety Reine Claude, which in French means “Queen Claude”.

In honor of the French queen Claudine, a variety of plums was named Renclode.

It so happened that in Europe this particular variety is called "renklod". But here, in Russia, it is called "Green Renklode". Other varieties appeared, very similar in all respects to French hybrids, and over time it was necessary to give them clarifying names.

In most re-clauds, the height can reach up to 7 m. The crown of the tree has rounded outlines (you don't even need to carry out the formation from you), and some flaws do not deviate from the norm. Flexible, easily bending young shoots of red-brown or red-green color have slight pubescence. Over the years, the bark becomes stronger, denser, becomes gray and loses hairiness.

Some varieties of renklods can reach 7 m in height.

Pubescence is also present on the surface of the petioles and the underside of the leaves. The hairs are the longest along the veins. Over time, the petioles become reddish.

The shape of the fruits of the renklode is spherical or similar to an egg, pointed on both sides, up to 5 cm in length. The color can be from greenish yellow to reddish purple. The surface is slightly rough, covered with a thin layer of waxy coating, which can be easily erased. The fruits are famous for their very sweet, "marmalade" juicy pulp.

For the rest of the characteristics, the renklod is similar to the Hungarian plum. The overwhelming majority of representatives of the group are self-infertile. Blooming begins in May, and for this short period, plums can be a real decoration for your garden. Trees do not bear fruit every year, and it is not possible to trace the frequency. The warm, sunny summer period with dry weather is of great importance for the yield.

Fruits of the grade Renklod collective farm

Fruits are medium in size, yellow-green in color, rounded with flattened tops. The plum is sweet, but slightly sour. The side of the fruit overlying the edge of the bone is often better developed than near the blunt edge. Berries on the sunny side sometimes take on a brownish blush. The skin of the plum is matte, thin, covered inside with small grayish dots over the entire surface. Fruit weight - on average 20 g. The abdominal suture does not stand out, in contrast to the lateral suture at the stone. The plum contains a huge amount of substances useful for the human body. It is the leader in the amount of substances such as potassium and group P vitamins in the pulp. They have a positive effect on the work of the heart and strengthen the vascular system.

The main characteristic of the collective farm Renklode plum is a bountiful harvest. The yellow pulp of the fruit is juicy, with a very delicate structure and medium density. A small bone separates from the pulp quite easily. The fruits have a sweet taste with a slight sourness. Plum tastes very pleasant, juicy, it can be eaten both fresh and made from jams, juices, marmalade and other preparations for the winter. The slight bitterness of the peel gives it a subtle shade. The flesh of the fruit is light green in color, tender and firm. The variety begins to bloom late, the berries ripen at the end of August.

The beginning of the fruiting period depends on the planting method: in root suckers, it occurs at 6 years, when planting a grafted seedling - one or two years earlier. The harvest is plentiful, from one young tree, at the age of 6 years, you can collect up to 8 kg of plums, from an adult (over 10 years) - about 40 kg of fruits. The maximum possible yield is 51 kg. Due to the number of ovaries, branches can sag, because the crown becomes flat in shape. The crop must be collected quickly, otherwise the plum will begin to crumble.

Renclaude Altana

Renklod Altana is another popular variety, originally from the Czech Republic. It was bred there in the middle of the nineteenth century by sowing the seeds of Green Renklode. On the territory of Russia, the hybrid was zoned in the Lower Volga and North Caucasian regions in 1947.

Its attractive fruits grow large, over 30 grams. They have an elegant pink-red color and a rounded shape. Plums are tasty, juicy, with a small pit that can be easily separated from the pulp. They ripen in 2-3 ten days of August.

Yields are good, but may fluctuate over the years. Trees respond well to planting with a number of pollinating varieties and themselves, in turn, are effective in this capacity. Strong pruning is recommended, with intensive pruning of young shoots. Then the plants begin to bear fruit for 4-5 years. Approaches the appearance of fruit and the tying of branches in a horizontal position.

Not all gardeners are suitable for the size of trees of this variety, since they reach 5 meters and may not fit in a small summer cottage. Now the hybrid has somewhat lost its popularity and is losing ground to the improved Karbyshev's Renklod, which is similar to him in fruit appearance and ripening times.

Plum Renklod collective farm: pollinators and grafting

This variety is self-fertile, meaning it needs pollinators to set fruit. Pitted plum can also be used for rootstock. The seeds of this variety germinate and develop quickly. The plant cannot be cross-pollinated with the Chinese variety. The best pollinators are the varieties Skorospelka Krasnaya, Vengerka Moskovskaya, Eurasia 21, Large-fruited blackthorn, Volzhskaya krasavitsa. It is optimal to use two types of home plum at the same time.The collective farm Renklod is propagated most often by grafting plums onto another tree. The onset of fruiting depends on the stock. The procedure is carried out in early spring, when the plants have not yet woken up. The most common method is by grafting plums into the cleft. Other options are possible, for example, grafting under the bark or in a cut on the side, but this method can be practiced only after the start of active sap flow.

Reproduction methods

Plum is propagated by seeds, grafting and removal of near-stem shoots, if any. The grafted trees do not produce overgrowths with signs of re-clod. With the seed method of propagation, seedlings are used as a stock. Large bones are cleaned, dried, placed in wet sand (sawdust can be used) and stored for 6 months at temperatures from 0 to -10 ° C. Then they are germinated in fertile soil and the seedlings are planted in the ground. During the active sap flow of trees, grafting is performed.

When propagating by shoots, the root connecting it to the mother tree is cut in the fall. In the spring, they dig up a shoot and plant it in a new place.

Features of the variety Renklod kolkhoz

One of the main advantages of the variety is its very high yield and the ability to withstand harsh cold weather. Other features:

• Thanks to the smooth trunk, the tree is not susceptible to sunburn.
• The seeds of this homemade plum are an excellent stock material. They sprout very well and are easy to use for plant propagation.
• The fruits are soft, tasty, medium-sized and attractive.
• Fruiting occurs early enough, and often already in the sixth year, a bountiful harvest of plums can be harvested.
• The fruits begin to ripen around mid-August.

Among the disadvantages are the following:

• the fruits stick weakly on the branches and quickly crumble when they are overripe,
• own-rooted plums of this variety develop strong growth.

Reviews of gardeners on the results of cultivation

Basically, summer residents speak positively about the Renklode culture. “When I was buying a green sapling, the seller advised me to plant an Italian Hungarian tree next to it. The first harvest, obtained in the fourth year, was small, but the fruits were pleasing. In subsequent years, the volume of the harvest increased every time. I was satisfied, it is worth trying to plant another variety for a change. "

Danila, 27 years old, Ivanovo

“The Renclode Bove variety is very productive. In the 10th year, he was already giving up to 50 kg of plums. The fruits are delicious, I made jams and preserves - everyone loved it. I planted one more tree of a different type "Altana". I hope it will please us with the harvest too. "

Daria, 41 years old, Yekaterinburg

“At the dacha there are 3 varieties of renklode growing -“ altana ”,“ medovka ”and“ anna shpet ”. In the black earth strip, trees feel normal, they can be grown. The tastiest of all is "altana". The harvest is excellent, compotes can be canned. "

Sergey, 47 years old, Togliatti

The varieties of plum renklode are currently being replenished with new hybrids, for example, "entertaining", "blue dar", "Sukhanovskaya", "Michurinsky". Breeders are improving the species, trying to improve the main advantages of plums and their resistance to natural troubles.

Planting and leaving

Planting of yellow Renklode kolkhoz plum in central Russia begins in the spring. There is an option for autumn planting, but then there is a great risk that the tree will not take root if it does not develop a root system of sufficient size. With this method, seedlings often freeze out, not having time to get strong enough for a full winter. If it is not possible to wait for the onset of the spring thaw, in order to plant a plum, you will have to dig it on the site and cover it with a thick layer of coniferous spruce branches for the winter, and sprinkle it with snow in winter. In this way, the chance that the seedling will successfully survive the frost can be increased.

The place for planting plants is chosen as well lit as possible, but with protection from cold drafts. It is best to choose the southeastern part of the garden plot or plant a plum in the south. It is important to plant the tree in a place where other plants will not cover it with their branches. In the shade, it will develop more slowly and fruiting will not come soon. Before planting a plum sapling, you should choose the right soil and prepare the planting hole. For this variety, it is best to use loamy soil, the acidity of which is 6.5-7.0 pH. Groundwater should not be too close to the root system of the plant. The minimum distance to them is 1.5 m.

A brief excursion into history

The progenitor of the variety of varieties of renklods is "Green Renklod", another name is "Greek plum". Thanks to him, many varieties appeared, bred in Russia and Western Europe. His descendant is the "Soviet Renklode".

They took him out on the basis of the Rossoshansk experimental station. The variety was obtained by crossing the varieties "Record" (high-yielding plum) and "Renklod Ulyanishcheva" (famous for large fruits, their weight is fifty grams or more).

The novelty variety "Renklod Soviet", which was named in honor of the successful work of Russian breeders, has become widespread on collective farm garden plots and in private gardens. In 1986, the variety was acclimatized in the Central Black Earth region, since that time this plum has been successfully grown in Voronezh, Kursk, Belgorod, Lipetsk, Rostov-on-Don and their regions.

How to prepare a landing pit

The preparation of the planting pit begins two weeks before the start of work, but sometimes it is better to do this in the fall. The diameter of the pit should be about 70-80 cm, and the depth should be 0.5 m. If you plan to plant several seedlings together, the distance between them should be 3 meters. It is very important to properly prepare the soil, making it fertile and nutritious. To do this, 8 kg of compost and humus are introduced into a freshly dug hole, adding 100 g of wood ash to the mixture. Organic matter can be replaced with a complex mineral fertilizer consisting of 200 g of superphosphate with the addition of 80 g of potassium sulfate. 50 g of fluff lime is added to the acidic soil. A mixture of soil and fertilizers is thoroughly mixed and poured into the pit. A small hill is made in the center and a tree is placed on it, carefully straightening the root system.

A peg is inserted from the south side so that the seedling is stable and does not break from sudden gusts of wind. The hole is evenly covered with nutritious soil, the tree at this time needs to be shaken a little so that the soil fills all the voids between the roots. The root collar must not be buried in order to avoid rotting. It should be 6 cm above ground level. When planting is over, it remains to water the plant abundantly. To do this, you will need 2-3 buckets of water, which is poured into a near-trunk circle, having previously made it into a narrow furrow to facilitate watering. It is important to regularly moisten the soil around the tree during the hottest months, this also applies to mature trees, otherwise you can completely lose the crop: the fruits will begin to crack and fall off. Regular watering is required during the period of fruit setting and flower buds.

Then the plum must be tied to a peg, and the soil around it must be mulched with peat chips, sawdust, humus or other material. After two weeks, the seedling will again need abundant watering. Plum Renklod kolkhoz is a moisture-loving variety, like most trees of this species. With insufficient watering, the soil around it cracks, and the foliage begins to turn yellow and fall off. The optimal amount of moisture is when the water goes 40 cm deep into the ground. Therefore, it is so important to mulch the trunk circle and keep it clean, getting rid of grass and litter - this will help keep water inside the soil. One of the mandatory rules for caring for the drain is the regular loosening of the soil around.It relieves the plant of weeds and prevents the appearance of pests.

It is possible to decorate the trunk circle with border tape, but it is not recommended to use metal or concrete blocks. It is important to regularly remove excess shoots - about 5 times per season, otherwise the yield is greatly reduced, because the shoots require nutrients and take them from the mother plant. They cut it out entirely, without leaving hemp, the cut points are treated with garden pitch. Autumn is dug up the ground around. Watering is stopped at the end of August, otherwise the shoots will continue to grow, but it is important to be guided by weather conditions and regulate watering, depending on them. In dry years, it is better to continue watering the tree until the onset of frost.

Growing features

Choosing a landing site

To grow this variety, you need to carefully and correctly choose a suitable site. In this regard, you need to know in what conditions the Renklod Kolkhozny variety should grow:

• The variety is not very picky about soils. Saplings can be planted on black soil, sandy loam and loamy soils.
• Saplings love enough sunlight throughout the day.
• The variety should not be planted in lowlands, where spring frosts and flooding by thawed floods are possible.
• The root system of the tree reaches 3-4 m and does not react well to the close location of groundwater in the territory of the selected site.
• Perennial weeds such as sow thistle, euphorbia and wheatgrass use a lot of moisture and microelements from the soil. Therefore, it is necessary to choose a place for planting varieties with a minimum amount of the aforementioned weeds.
• The site must be well protected from strong gusty winds.

Purchase and selection of a seedling

Those who wish to purchase a seedling of this variety are faced with the question of where to purchase planting material. Given that the variety is quite old, you need to find out in advance where the fruit nurseries are located and whether they have the variety you are interested in. Unfortunately, seed production by Renklod Kolkhoznoy is practically not carried out in these nurseries. Therefore, you need to look for seedlings from private gardeners. When buying a seedling, you need to carefully study its appearance and compare it with the recommended indicators:

• The height of the seedling is 100-110 cm.
• The trunk is smooth without curvatures and outgrowths.
• The root system is developed. Consists of two to three large anchor roots and many small roots.
• The root system must be viable with sufficient moisture in the tissues.

Landing

You need to plant a seedling in early September. Such a planting contributes to the fact that during the autumn period (September - October) the seedling will be able to take root and winter well. Landing must be carried out competently and in a short time. After all, gross mistakes during planting can slow down growth or lead to the complete death of the planting material. Planting a seedling should be done in the following sequence:

• Using a shovel, they dig a hole measuring 75 x 75 x 80 cm.The distance between other trees or buildings should not be less than 6-7 m.
• For better survival and rapid initial growth, it is necessary to place nutrients in the planting pit: compost (9-10 kg.) And nitroammophoska (40-50 g.). To provide the seedling with all the necessary microelements, it is recommended to add 30-40 g of wood ash.
• A wooden stake is driven into the middle of the prepared and fertilized hole and a seedling is placed near it.
• Gently spread the roots in different directions and sprinkle with loose earth. Having filled up the hole, they tamp the soil around the trunk of the seedling.
• The root collar of a properly planted tree should be 3-4 cm higher than the ground level.
• The seedling is tied with a rope to a wooden peg and additionally watered with 10-15 liters. water.

Watering

During the cultivation period, the Renklod Kolkhozny variety needs watering. Watering is especially important in the process of flowering and fruit growth. The frequency and volume of watering depends on the age of the tree:

• In the year of planting, watering should be done every 3 days. Water in the evening with a rate of 15-20 liters.
• In the second season, watering is carried out once a week, spending 20-25 liters per tree. water.
• In the third year, trees of this variety already have a well-developed root system, which penetrates to a depth of 1.5-2 m. Therefore, the frequency of watering is gradually reduced to one watering every two weeks. In this case, the water consumption increases to 35-40 liters.
• In the fourth year, the variety needs to be watered only during the drought period.

Weeds

Weed control plays a very important role in obtaining high yields of this variety. A walk-behind tractor equipped with a milling cutter is very suitable for loosening the soil. Milling allows you to process large areas in a short period of time and very effectively destroy weeds. It is necessary to loosen the soil by at least 4-5 cm. Starting from the fifth year of cultivation, weed control can be stopped. At this age, the Renklode Kolkhozny plum trees compete very effectively with weeds.

Top dressing

Top dressing of this variety allows you to increase the volume of grown hearths by 45-50%. The main requirement of dressings is their correct dosage and timeliness of carrying out:

• Plums need nitrogen in early spring. In this regard, at the beginning of March, ammonium nitrate (50-60 g per 1 m2) is scattered around the trees and in the aisles on the soil surface.
• When foliage is blooming (end of April), trees should be sprayed with Pennant (20 ml for 5-6 liters of water). This drug acts as a regulator on trees, promoting their rapid growth.
• Before flowering, you need to feed the tree 5-6 liters. diluted liquid mullein in a ratio of 1:10. To do this, a hole is made around the trunk and the above solution is poured into it.
• After flowering, it is necessary to spray the tree crowns with a solution of nitroammofoska within 5-6 days. This solution is prepared by dissolving 30 g of crushed fertilizer in 8 liters. water.
• After harvesting, 6-7 liters are poured under each tree. fermented chicken droppings. In this case, the ratio of fertilizer to water is 1:13.

Pruning

Trees grade Renklod Kolkhozny need pruning twice a year. The first pruning is done in early March and the second in late autumn (late October). This pruning frequency is due to the fact that the trees of this variety grow rather quickly and form a large number of shoots on the trunk. In the process of trimming, remove:

• Dry shoots and branches.
• Growth on the trunk.
• Annual shoots growing in the wrong direction (in the middle of the crown) and disturbing the illumination of the crown.
• There should be no more than 4-5 main (skeletal) branches in the crown.
• All shoots should point 45 degrees away from the trunk.
• Shoots heavily damaged by diseases and pests are removed.

Pest and pest control

During their development, plums can be damaged by: gall mites, yellow plum sawflies, moths and aphids.

Gall mite. This pest forms growths (galls) on young shoots. Ticks feed on tree sap and can reduce the yield by up to 20%. Damaged shoots begin to dry out and die completely. Ticks overwinter in galls. Control measures:

• Spraying trees with insecticides in spring, when the mite leaves wintering.
• Removal of shoots with significant presence of gall outgrowths.

Yellow plum sawfly. It resembles a small yellow-brown fly. Body length 4-5 mm. The larva is harmful and destroys the ovary. One young individual lays up to 55-60 eggs in a bud. The larvae that emerged from the eggs begin to massively damage the ovary, and one larva destroys at least five buds. Control measures:

• Digging the ground around the trees in the fall.
• Spraying with insecticides Karbofos, Metaphos.
• Until the beginning of summer, adults are sprayed with an infusion of wormwood, which leads to a violation of the orientation of the pest.The strong aroma of wormwood prevents sawflies from finding trees of this variety.

Plum aphid. Aphid colonies form on the undersides of plum leaves before flowering. They feed on cell sap. They cause curling and drying of leaves. Control measures:

• Spraying the crown with soap-ash solutions. In 10 liters. 1 g of ash is dissolved in boiling water and 100-150 g of soap is added for better adhesion of the solution.
• Spraying with Karbofos insecticide (15%). There are two treatments. Before bud break and after flowering.
• Processing with dissolved laundry soap. 250 g of soap is crushed and dissolved in 8 liters. water.

Plum moth. An adult pest looks like a gray butterfly. She lays eggs on the fetus. The hatched larvae begin to be drilled into the fruits, thereby causing them to stop growing and shatter. Control measures:

• Hanging baits on a tree consisting of cans of beer or fermented compote.
• At night, straw smokes potatoes, wormwood and tomatoes. This smoke is toxic to the pest.
• Spraying with insecticides Permethrin or Cypermethrin.

Fight disease

The variety is affected by fungal diseases in rainy and humid weather. Plum bush. Infected trees form a large number of short and slender shoots in bunches. This disease is not cured, therefore, preventive measures must be taken:

• Planting non-infected seedlings.
• Application in the process of growing mineral and organic fertilizers.

Gum therapy. This disease occurs under the influence of a fungal infection during the period of insufficient watering or excessive feeding of the tree. A symptom of the disease is the formation of cracks and wounds on the trunk and shoots. From these lesions, gum begins to stand out, which later solidifies. Without proper treatment, this disease can develop into cancer. Control measures:

Spraying the affected areas of the tree with a 1-2% solution of copper sulfate.

Harvesting

Harvesting of fruits must be carried out in a timely manner, as overripe fruits begin to crumble en masse. You need to pick the fruits together with the stalk. This way they are stored longer. Plucked plums are sorted and sorted into wooden boxes. Long-term storage of the grown crop is carried out in a pre-prepared room with an air temperature of +2 degrees.

Correct feeding

Plum feeding begins in early spring. But, having acquired a seedling, he should prepare special conditions for it to take root and bear fruit abundantly. The planting pit is prepared in advance by adding organic fertilizers, superphosphate and potassium sulfate to it. Substances containing nitrogen are not introduced. They start feeding the plum tree the next year after planting.

The area from which the tree receives nutrients is approximately 9 m2. Once every 3 on nutritious and annually on poor soils, organic fertilizer, a bucket of compost or humus per 2 m2 are applied under the root for feeding plums. You can add superphosphate to organics. In March-April, when the tree has not yet begun to bloom, 20 g of ammonium nitrate and urea are added to the trunk circle per 1 m2. When the fruits are poured, they are fertilized with urea and nitrophosphate, adding 30 g of the substance each. After harvesting, they are fed again with superphosphate and potassium sulfate. The last time fertilizers are applied in the fall, without adding nitrogen to the composition.

Things to consider when leaving

If a seedling blooms after a year, all flowers are removed so that the tree gains strength for the next year. The crown is regularly pruned in early spring, in addition, sanitary pruning is done during the season, removing dry and growing inward branches. For 3 years, the tree is fed. When leaving, during spring watering, they bring under the tree:

• 250 g of mineral fertilizers;
• 50 g of potassium salt;
• 20 g of ammonium nitrate.

Trees are fed during flowering and fruiting with urea and nitroammophos. Before winter, the space near the tree trunk is covered with humus, straw, and the stem is whitewashed.

Pruning plum

Correct pruning helps to regulate the size and flavor of the fruit, the yield and the size of the tree, as well as prevent the development of diseases. The shoots of young seedlings are shortened by a third to stimulate the establishment of the crown. To shorten the plum branches, without the risk of reducing the fruiting of the variety, one should take into account its such feature: most of the fruits are tied on bouquet shoots, and only a few on last year's ones.

A young tree must be formed by pruning branches and leaving only 4-6 skeletal shoots. In adult plants, branches are removed that have bent to the ground under the weight of the fruit. Every 3 years, the main shoots are cut to a third of their length, weak ones are removed, leaving only straight and strong ones. You need to be careful about tops and not confuse them with strong branches when pruning. Sanitary pruning is also necessary to prevent the spread of insect pests and diseases. The crown is thinned out, diseased and broken branches, as well as non-fruiting shoots, are removed.

It is necessary to start forming the Kolkhoz Renklode plum in early spring, and not in late autumn, so as not to harm the trees. If part of the tree needs to be removed, the stumps are not left, trimming everything to the base. When the annual growth began to decrease sharply, the shoots are shortened to two-year-old wood. But you cannot cut off a lot of branches at once, otherwise the plum may die. No more than a quarter of the entire crown is removed at a time. With a seedling height of 2.5 meters, they begin to limit vertical growth so that the branches become more spreading and the sun's rays pass through them better. This will allow the side branches to develop.

Once the tree is planted, the lower branch is pruned into a good bud to remove the top with undeveloped buds at the top of the growth. All other shoots are cut at the bottom level. You can turn the branches that do not fall into the skeletal part of the crown into semi-skeletal ones, if you cut them more strongly or bend them, transferring them to an inclined position. A narrow crown can be made wider if the main branches are cut into second-order shoots that are oriented in the opposite direction from the trunk.

Region of natural growth

Usually Renklods are grown in Western Europe. In Russia, however, such varieties can most often be found in the Central region or in the south of the country.... Stopping your choice on such a family, you should take a responsible approach to the choice of a subspecies, so that it can easily endure the climatic conditions of the growing region.

Renclode is not suitable for areas with harsh weather conditions. Most often, trees do not tolerate spring frosts and cold below -25 degrees.

Preparation for wintering

Kolkhoz renklod is one of the most winter-hardy varieties of plum. It is characterized by excellent endurance performance. Normal frosts are easily tolerated by adult plums and practically do not freeze without shelter, even in severe cold weather. But young seedlings are not yet hardened, therefore they need additional shelter for the winter. Low temperatures can destroy delicate trees: they are insulated with a layer of sawdust and covered with spruce branches around the trunk circle. In severe winters, small branches of adult plants sometimes freeze slightly, but this practically does not affect the fruiting period, usually the plants recover after a year. This variety of plum is one of the most resistant to frost and sudden temperature changes.

There is another option for preparing a seedling for winter: a structure of arcuate guides is erected above the tree, covered with straw or hay on top and secured with a rope or twine. Snow will serve as an additional insulation, because such a structure will reliably protect the drain from frost and drafts.Other covering materials can be used. It is also recommended to wrap the tree trunk with insulation, for example, nylon. This will protect the bole from the encroachment of rodents and other small animals.

Breeding history

Renclode began to be grown in France in the second half of the 16th century. King Francis was the first during his reign to receive a variety of plums as a gift, bred with the Verdicchio plum.... After the king tasted the gift, he demanded to name the brought variety in honor of his wife Claudine (Claude), noting that the taste of these fruits is as delicate and sweet as the appearance and character of the queen.

Plum Rene Claude

The name of this variety ReineClaude is translated from French as Queen Claude.

Then gradually hybrids began to appear, similar in taste to Renclaude. They began to be combined into one group, while giving each variety its own individual, clarifying name.

Disease prevention

Plum Renklode collective farm, planting and caring for which is not difficult, is practically not susceptible to fungal diseases: it can suffer from infection only in wet years. The tree is resistant to gum flow. For prevention, rejuvenating pruning is carried out: diseased and dried branches, leaves and fruits are cut and burned. The resulting cuts and cracks are treated with garden varnish or a mixture of milk of lime and copper sulfate. Before the first leaves appear in the spring, the whole tree is sprayed with a solution of Bordeaux liquid, and in the fall they are treated with urea to reduce the risk of clasterosporium disease. It is important to correctly observe the processing time and carry out prevention at least 30 days before the start of the harvest.

Destruction of pests

Plum pests are most often found in fruits and under the bark. The most dangerous for the Renklod variety are the collective farm plum sawfly and the moth. Weakened plants especially suffer from these insects, for example, after abundant fruiting. Plum pests should be started in early spring: Trees are sprayed with special preparations several times, depending on the phase of development of the larvae. To combat the moth, for the best effect, about 5 treatments are carried out with a difference of 10 days. Sticky traps made of burlap, preventive collection of fallen leaves, and regular loosening of the soil also work well. When fruits are tied on a tree, you should regularly remove damaged plums with pests inside, collect and burn them. Moths can hibernate inside the bark of trees, so you need to regularly remove exfoliated areas. In private households, it is recommended to carry out treatment with biological substances that are safe for humans, and not to use chemistry. Then the fruits will not contain dangerous impurities.

Kolkhoz renklode is a classic plum variety that is not inferior in taste to most modern hybrids. The tree is characterized by increased winter hardiness, which is very important when grown in areas with cold climates. The variety is time-tested and is still in demand by summer residents. Properly caring for it, every year for the season you can collect a rich harvest and enjoy delicious fruits.

Main advantages

Renclode plums have good taste. In addition, the variety has a large number of other advantages:

• 
  beautiful appearance of the fruit;

• high frost resistance;
• unpretentious care;
• good yield.

Gardeners consider the disadvantages of the variety to be the need for additional planting with a number of pollinating plants, since most varieties are self-fertile.
