Manchurian walnut: cultivation

To grow a beautiful and unpretentious plant in care, it is enough to purchase a seedling or fruit and take into account the recommendations for planting. It is worth knowing that a tree or shrub can grow on all types of soils, except for acidic ones.

Walnut seedlings are difficult to tolerate transplants

Manchurian walnut planting and care

Those who wish to decorate the site and enjoy the taste of the Manchurian walnut in autumn should plant according to the rules described below. When choosing a place, it is worth considering that the plant is light-loving, does not like acidic soil, and requires constant soil moisture (especially in the early years). Location in the shade of other trees, next to buildings is unacceptable. There must be a distance of at least 10 meters between two Manchurian nuts. There are no special rules for care, except for watering and fertilizing the soil.

Planting a seedling

You can plant seedlings in the spring or autumn season, months:

September;
April.

The pit should be prepared in advance, at least thirty days in advance. The depth of the pit is from eighty to one hundred meters. Scheme:

We dig a hole. The top soil is laid out separately from the bottom.
The bottom is drained with bricks, gravel, etc.
We mix the upper and lower soil, spread the mixture on top of the drainage.
Clay or depleted soils need to be fertilized. To do this, add humus, sod, sand 4/2/2/1 in parts to the upper part of the soil. Add potassium superphosphate to the mixture in the amount of 20 grams (up to 40 is possible) and potassium fertilizer. The resulting mixture is laid on top of the drainage.
A month later, we dig a hole for a seedling.
We cut the central part of the root.
We pour out the excavated soil, but not all.
We put the seedling in the soil, check the level of the neck of the root with a wire or a wooden stick. This part should be flush with the soil. You can also attach the seedling to a peg.
Fill with a bucket of water.
As moisture is absorbed, lay out the rest of the soil.
We make a hole around the seedling.
Pour water - you need ½ bucket - a bucket.
We spread peat, sawdust or mature compost on top. Mulching will help retain moisture.

It is very important to pay attention to the conformity of the neck of the root with the level of the soil. The parameter will avoid subsidence. Landing in a fresh pit that has not aged for a specified period of time can lead to incorrect formation of the root part. Root pruning promotes accelerated tree growth.

How to grow a Manchurian nut from a stone

When planting seeds, it should be noted that the germination rate of fruits not prepared in advance is rather low. To do this, nuts must be kept in the refrigerator during the winter or planted in the fall. Step by step diagram:

At the chosen place, we form a bed, dig it up, add wood ash in an amount of 2 to 3 glasses per square meter.
We make recesses up to 8 centimeters.
When planting several nuts, the distance between the holes should be at least 10 cm.
The nuts placed for 30 seconds in kerosene are laid with the sharp side down.
We fill the holes with soil.
We spread peat, sawdust or compost.

Processing with kerosene will avoid damage to the planted seeds by rodents and other pests.

Care

During the first year, seedlings from the seeds can not be touched, and in the second year they can be planted in permanent places. Watering frequency:

the first year - at least two and no more than three times within a month;
second-third - two times;
further - one.

After watering, the soil must be loosened, weeds must be removed. You need to fertilize the soil in June, it is better to use potassium superphosphate for these purposes. In the spring it is necessary to carry out whitewashing so that in hot weather the trunk is not subject to burns. Before winter, young trees need to be covered with non-woven materials.

Watering is carried out 2-3 times a month, without flooding the soil

Manchurian walnut tincture is prepared very simply: about 2 liters of alcohol (vodka is also possible, but the higher the degree, the better), about 100 pieces of nuts (preferably green ones). Nuts must be passed through a meat grinder and poured with alcohol. Put the workpiece in a cool dark place for a month, then squeeze and store in the refrigerator, gradually taking a maximum of 3 tsp.

For external use, you can prepare an oil tincture of Manchurian walnut: insist 50-60 g of green leaves in 300 g of unrefined sunflower oil, keep in the cellar for 2-3 weeks, then squeeze it out, use it as a healing ointment for healing burns, frostbite, wounds and against skin diseases.

Contraindications

Like everything in the world, this tincture has contraindications: lactating mothers and pregnant women should not use it, with gastritis and ulcers, cirrhosis of the liver, patients with elevated levels of prothrombin should also not be used. There may be individual intolerance. Since it is a very powerful antimicrobial agent, it also suppresses the beneficial intestinal microflora. In order to avoid dysbacteriosis, drink fermented milk products intensively: kefirs and bifid-containing yogurts.

Manchurian walnut has unique antimicrobial properties. This allows the walnut tree to cope with harmful organisms on its own. But there are cases when a hardened plant fails to avoid ailments.

Diseases

A few diseases of the Manchurian walnut affect the health of leaves, branches, shoots, and bark. Each disease progresses with its own characteristics. It is important to help the plant in time so that it does not die. It is even better to take preventive measures in time.

The leaves turn black

In wet weather, under favorable conditions, the walnut tree is often affected by bacteriosis. It manifests itself in the form of blackened edges of the leaves. Later they may completely turn black. The walnut often faces exactly the same problem. Sometimes bacteriosis can affect up to 40% of the crown. Later, the fruits are also exposed to the disease.

In the fight against bacteriosis, it is recommended to use a fungicide from the copper group. Often used Bordeaux liquid (3%) or urea (1%). Will bring results and processing of each leaflet copper chloride 0.7%. Spraying is best done immediately after the appearance of blackening.

As a preventive measure, treatment must be performed at least twice during the growing season. In some cases, surgical measures are recommended. It is better to cut the affected branches at a distance of 20 cm from the place of blackening.

Important! To eliminate all sources of infection, in the fall it is necessary to collect fallen leaves and burn them. Deep plowing of row spacing will also help eliminate harmful bacteria.

Leaves turn yellow

Much has been said about the frost resistance and winter hardiness of the Manchurian walnut tree. But sometimes it suffers from late spring frosts. At this time, tender young leaves and shoots cannot survive night frosts down to -3°C. Over time, they begin to turn yellow, then dry, blacken and fall off.

This phenomenon can be observed at the end of May. Young foliage begins to form in spare buds. Another reason for the yellowing of the leaves may be a lack of water in the summer. In the hot season, it is necessary to monitor timely watering, the tree should not dry out.

brown spots

Sometimes there is another ailment of the Manchurian walnut - brown spotting or marsonia. Sometimes this disease is also called marsoniosis or anthracnose. This is a type of disease caused by ascomycete fungi. Marsonia is able to infect not only leaves, but also shoots, fruits. Because of it, the yield can drop by 80%, and the plant may not bear fruit at all over time.

The appearance of the disease is easy to recognize: the foliage of the walnut is covered with brown-brown spots, which begin to grow over time. Not only brown rashes appear on the pericarp, but necrotic cracks also appear. In them, the pathogen can overwinter, and the next year again provoke a new focus of the disease.

Marsonia more often infects walnut trees in places with humid air, during periods of heavy rainfall, fogs. Brown spots can be eradicated by spraying Bordeaux mixture with a saturation of 3%. For a complete victory over the disease, spraying must be carried out not once, but two or three. In autumn, all fallen leaves from an infected tree must be burned.

The bark peels off

Bacteriosis can be a problem for walnut bark. This disease was called “bark cancer”. As a result of its development, asymmetric dark brown dead areas are formed on the trunk, branches.

Over time, the bark begins to flake off, the branches dry out. The development of cracks in the bark occurs in the summer, in winter the process is slowed down. Bark cancer affects mature plants, not younger than 10-15 years.

To prevent the development of any type of Manchurian nut bacteriosis, it is necessary to act in three directions:

Fight bacteriosis of fruit-bearing trees. First of all, it is necessary to cut off the infected branches, branches. Pruning is best done in the spring, when the buds are just beginning to bloom. Sections require putty with garden carbolineum. Also, putty can be prepared from lard, nigrol, wax, rosin, taken in equal parts. Wax and rosin can be replaced with ordinary stove ash, which has antifungal properties.
Fight infection of young crops. Cleaning wounds on young trees is best done at the very beginning of their appearance on the bark in order to eliminate bacteria from the wood. Also, disinfection of young plants can be carried out under the root. To do this, bleach is added to the soil at the rate of 150 g per square meter. It is difficult to process young plantings, where there are a lot of seedlings. If they become infected with bacteriosis, they tend to grow poorly, form a bush, not a trunk. Young shoots of one year of age can already be sprayed with 1% Bordeaux liquid.
Carry out preventive measures when growing improved plant varieties. When breeding Manchurian or Dumbey walnut, all attention should be paid to agricultural technology. It is important to develop a culture resistant not only to frost, but also to bacteriosis. Before planting a walnut seedling, it must be carefully examined. Trees with defects in roots, trunk, leaves must be rejected or disinfected in a solution of 1% copper sulphate and liquid clay.

Important! In addition to Bordeaux liquid and copper sulfate, fungal diseases can be fought with a well-known drug.« Fundazol» . The interval for the procedure should be at least two weeks.

Leaves dry

In addition to diseases, improper care also affects the health of the walnut tree. All year round it is necessary to help the plant maintain a cheerful appearance. Improper watering, top dressing, organization of wintering lead to the fact that the leaves begin to turn yellow, and then dry out.

Many inexperienced gardeners cannot understand why there are problems with walnut leaves, because they treat them with preparations in time. Sometimes the cause of this phenomenon may be poor drainage for the root system. Every year it is necessary to carry out the procedure of whitewashing the trunk and skeletal branches.

Problems with leaves after planting seedlings

In young plants, the crown may also suffer from diseases and improper care. The Manchurian nut loves fertile soil, so the land around the seedlings should be fed with ammonia, phosphorus, and potash fertilizers. So that the foliage does not fade, it is necessary to water the young tree abundantly in the heat 2-3 times a month.

Important! Before the onset of cold weather, young plants must be insulated. Closer to the trunk, a mulch of humus 10 cm high is laid.

Pests

Infection of a dumbey tree with fungi leads to damage to the plant by a gall mite. This pest attacks the nut during a period of high humidity. He chooses young leaves and only emerging fruits for nutrition.

Photographs of an infested tree show the following signs of the walnut wart mite:

leaves are covered with dark brown tubercles;
young shoots grow slowly;
sheet plates dry and curl;
the reverse side of the leaves is covered with a thin cobweb.

It is necessary to fight gall mites with acaricides("Aktara", "Akarin", "Abamectin"). They produce a neurotoxic effect on ticks. Spraying is carried out 2-3 times with an interval of two weeks.

Another pest of the Manchurian walnut is the nut washer. This insect has two pairs of wings. Nutworm affects the bark of shoots, flowers, leaves.

The insect deposits galls (special bags) on them. Shoots infected with nutworm must be cut and destroyed. If the insects managed to lay the larvae, and they hatched, then the plant must be sprayed 2% solution of chlorophos. Also, karbofos is suitable for processing (90 g per 10 liters of water).

How to prevent illness

To protect walnut plantations from diseases, it is important to carry out the following activities:

In the spring, it is necessary to loosen the soil under the tree, apply granular mineral fertilizers. For prevention from diseases and pests, even before bud break, it is better to treat the nut with complex preparations.
In summer, it is important to keep the area near the trunk clean so that weeds do not grow there, provoking the appearance of pests.
In autumn, the tree must be cut and sprayed again with the necessary preparations.
Closer to winter, the soil under the nut is dug up, late watering is carried out.

Did you know? The oldest representatives of the Manchurian walnut reach 250 years of age.

Diseases of the Manchurian walnut not only reduce the yield, but also spoil the decorative effect of the plant. Experienced gardeners try not to leave a tree unattended for a long time. It is important to help him in time.

What is the difference between a walnut and a Manchurian

The main difference between the Manchurian walnut and its close relative, the walnut, is frost resistance. Differences between the first and second:

stronger shell;
smaller cores;
the size of the fruits is approximately the same;
the second is more light-loving.

Botanical description

Under natural growing conditions, the Manchurian walnut is a massive tree up to 25 m high. It has a large spreading crown like a tent. Due to its decorative qualities, the plant can be used in gardening and landscape design. Thick foliage can protect from the scorching summer heat.

The leaves of the walnut are large, about 70 cm, combined from several lobes. They exude a strong specific smell that moths do not like. Flowering occurs in May, simultaneously with the dissolution of foliage. Since the plant is dioecious, there are female inflorescences - in the form of shortened brushes (up to 10-12 cm) and male ones - long (15-17 cm).

Fruiting begins at 6-9 years in wild representatives. Cultivated specimens mature only by 12-15 years after planting.

The fruit is represented by a round-elongated box 5-7 cm long, with a soft shell. Inside is a large nut, which contains an oily kernel. Its shell is strong. At first it has a green color, then it turns brown. In the description of the taste, there is a similarity with walnuts: the same oily, sweet and pleasant.

Manchurian walnut planting and care

Planting a seedling

You can plant seedlings in the spring or autumn season, months:

September;
April.

The pit should be prepared in advance, at least thirty days in advance. The depth of the pit is from eighty to one hundred meters. Scheme:

We dig a hole. The top soil is laid out separately from the bottom.
The bottom is drained with bricks, gravel, etc.
We mix the upper and lower soil, spread the mixture on top of the drainage.
Clay or depleted soils need to be fertilized. To do this, add humus, sod, sand 4/2/2/1 in parts to the upper part of the soil. Add potassium superphosphate to the mixture in the amount of 20 grams (up to 40 is possible) and potassium fertilizer. The resulting mixture is laid on top of the drainage.
A month later, we dig a hole for a seedling.
We cut the central part of the root.
We pour out the excavated soil, but not all.
We put the seedling in the soil, check the level of the neck of the root with a wire or a wooden stick. This part should be flush with the soil. You can also attach the seedling to a peg.
Fill with a bucket of water.
As moisture is absorbed, lay out the rest of the soil.
We make a hole around the seedling.
Pour water - you need ½ bucket - a bucket.
We spread peat, sawdust or mature compost on top. Mulching will help retain moisture.

How to grow a Manchurian nut from a stone

At the chosen place, we form a bed, dig it up, add wood ash in an amount of 2 to 3 glasses per square meter.
We make recesses up to 8 centimeters.
When planting several nuts, the distance between the holes should be at least 10 cm.
The nuts placed for 30 seconds in kerosene are laid with the sharp side down.
We fill the holes with soil.
We spread peat, sawdust or compost.

Processing with kerosene will avoid damage to the planted seeds by rodents and other pests.

Care

During the first year, seedlings from the seeds can not be touched, and in the second year they can be planted in permanent places. Watering frequency:

the first year - at least two and no more than three times within a month;

Description and characteristics of the tree

He is Manchu Doombey walnut belongs to the species deciduous monoecious trees or shrubs. It does not occur in the wild, it is protected in nature reserves. The main name comes from historical regions - Manchuria, China, Taiwan.

Today it is grown in the Far East, the Korean Peninsula, Sakhalin. He is close relative walnut, but differs in unpretentiousness to growth conditions. Along with cedar, it successfully bears fruit in Russia. In the broad-leaved forests of Primorsky and Khabarovsk Territories, it likes to settle along river valleys. Therefore, the fruits are also known as Ussuri walnut.

A tree 25–30 meters high with a highly spreading openwork crown lives 250–300 years. Broad leaves with a characteristic odor when rubbed in spring and summer are painted green. With the onset of autumn, they acquire a beautiful golden yellow color. At this time, the harvest begins.

The plant blooms in mid-spring. Male trees bloom long catkins, and female inflorescences are modestly collected in brushes. As you can see in the photo, the fruits covered with a green pericarp flaunt 3-7 pieces. When ripe, the coating bursts and disappears.

A drupe with characteristic deep wrinkles is born. In appearance, the fruit in the shell resembles walnut grade. But the Manchurian counterpart is smaller in size, and its gray color approaches a black tint.

Terms and conditions of storage

Raw materials for tincture are stored in canvas bags or glass containers. It is advisable not to expose the nuts to heat. Drying of leaves and fruits is carried out in a natural way. At elevated temperatures, the destruction of fatty acids occurs, which reduces the useful properties of the product.

The Manchurian walnut deserves to be planted and cultivated in every area. Walnut is beneficial at any age - both before fruiting and during fruiting. But due to the fact that on the same tree, male and female flowers bloom at different times, and this difference can reach 10 or more days, such flowers cannot pollinate each other, and the fruiting of the tree will not occur.

Therefore, in a single garden or household plot, remote from other areas with growing Manchurian walnut trees, a single walnut tree will never bear fruit.

Gardens should have at least two different trees. In collective gardens on neighboring plots, one Manchurian walnut tree can be grown. Manchurian walnuts should be grown more widely as ornamental and forest woody plants, and not only in gardens, but also in public gardens, parks and forest plantations.

Procurement and storage

The most concentrated vitamin composition of the nut is observed in the summer. Therefore, the optimal time for collecting raw materials can be called June-July. It is better to collect fruits and castings in dry and calm weather. You need to dry the material in the open sun, laying it out in a thin layer. The prepared material should be stored in a cool dark place. It is not necessary to split the fruits for storage. The leaves must be placed in a wooden or tin can, put the fruits in a box, cover with a thin layer of gauze. Periodically, you need to check the workpiece. If dark spots or mold appear on it, the fruit can be split open and inspected inside. If it looks damaged, the nut should be discarded.

Use in the decorative design of the site

The plant is great for landscaping. It can be formed both in the form of a shrub and in the form of a tree. The crown is sprawling, growing rapidly, so already 1 year after planting, whole compositions can be made from a young hazel. The culture is photophilous, so it is usually used as the highest part of the planting or planted in front. It is not afraid of the winds, so it is suitable for ennobling small hills and open areas that are not protected from gusts of air.

Hazel can easily be combined with both deciduous and coniferous plants. Looks best next to junipers, cedars, larches. Professionals plant hazel along the perimeter, forming a decorative fence out of it, or create compositions in the center of the site. The Manchurian walnut looks especially impressive against the background of green lawns lined with a rolled lawn.

The plant can be grafted to the Ussuri walnut. About 40% of vaccinations successfully take root.

Growing in the garden

For a tree, it is worth choosing a well-lit place with fertile, moist soil. A seedling should be planted in a permanent place in September or April. To do this, you need to prepare a hole, on the bottom of which you need to lay a layer of gravel or pieces of brick as drainage, it is also worth adding wood ash, humus, turf and sand to the soil. The depth of the hole should be determined so that the root system of the seedling fits freely into it.

After the seedling is installed in the hole, it should be covered with soil, compacted, mulched with sawdust near the trunk circle and watered well. If it is planned to plant several seedlings, then the distance between them should not be less than 10 m, since the tree grows quite large.

Manchurian walnut is a moisture-loving crop, so in dry summers it must be watered once a week. If there is enough precipitation, an adult plant is watered no more than 4-5 times during the summer, young trees (up to 3 years old) - 6-7 times.

As necessary, the soil should be loosened and weeded. After weeding, you need to mulch the near-trunk circle to retain moisture and prevent the rapid growth of weeds.

In the spring, before the foliage appears, pruning should be carried out - dry and damaged branches should be removed. Mature trees are not afraid of frost, but seedlings need to be warmed for the winter. To do this, they need to be covered with dry leaves, peat or branches, and it is advisable to wrap tree trunks less than 3 years old with burlap.

Application in cosmetology

For the treatment of skin and hair in women, dried walnut leaves are used. To prepare a medicinal decoction you will need:

2-3 walnut leaves.
One spoonful of dry wormwood.

How to cook the product at home - description:

tincture recipe

For the preparation of Manchurian nut tincture, slightly unripe fruits are used, collected at the end of July. It is at this time that they contain the greatest amount of valuable substances. It is better to make a healing extract on alcohol, and not on vodka, since the insufficient strength of the drink does not allow all the beneficial properties of the raw material to manifest itself and often leads to oxidation of the contents.

Preparing the tincture:

Wash 1 kg of unpeeled nuts and put in a jar;
Pour the fruits with 2 liters of 70–96% alcohol (or 40% vodka).
Add to 4 tbsp. l. honey (preferably acacia) and some spices.
The mixture is carefully moved, corked well and put away in a dark place for 4 weeks.

During the infusion, the jar must not be opened. It is very important that no air gets into it.

With proper preparation and storage, Manchurian walnut tincture will remain healing for 4 years. The color of the product may vary from light yellow to bright brown. It depends on the strength of the alcohol.

Advice. The best in its medicinal qualities will be an extract infused with 70% alcohol.

A drug prepared with vodka usually has a dark color. This indicates the oxidation of hydrojuglone and the saturation of the composition with water-soluble substances. Use such a drug should be for the treatment of the gastrointestinal tract. The classic version of alcohol tincture is colored yellowish green and is used to combat most of the diseases considered.

Rules for the use of tincture

So, how to take Manchurian walnut tincture? There are many ways to use extract. For the most part, they are not much different from each other, so we will consider only the most important and mandatory for study.

Reviews: "Not all patients respond to this treatment"
My aunt makes her own Manchurian walnut honey tincture by ordering nuts online. It turns out that this remedy contributes to the treatment of tumors, and two years ago my aunt was diagnosed with uterine myoma. So the doctor recommended that she add Manchurian walnut tincture to the medical treatment.
An endocrinologist advised my friend a Manchurian nut tincture to prevent problems with the thyroid gland. She has a high hereditary risk of developing hypothyroidism, since both the female and the male lines, everyone in the family is struggling with this pathology. The doctor said that the tincture is good, both for the prevention and treatment of hypothyroidism.
I know many cases from my practice (medical), the nut really gives a good effect. Small thyroid nodules decrease or completely disappear, the volume of the gland decreases. With fibroids, there is no growth of the uterus (this is an indicator of stability), sometimes myoma nodes decrease (but not much), the main thing is that the fibroids do not grow. Still nuts work wonders after chemotherapy - blood elements are quickly restored in quantity. Unfortunately, not all patients respond to this treatment. And courses of nuts should be held annually.
