What is the difference between a walnut and a Manchu

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

• stronger shell;
• smaller cores;
• the size of the fruits is approximately the same;
• the second is more photophilous.

In landscape design

Interestingly, the Manchurian walnut is even more decorative than the walnut. It is used for landscaping both suburban areas and cities, streets, courtyards. Parks and squares with Manchurian walnut plantings will become a very comfortable place for walking, as this culture repels mosquitoes thanks to phytoncides.

Manchurian walnut is very beautiful in autumn:

The greatest compatibility of this culture with conifers.

Manchurian walnut: cultivation

To grow a beautiful and unpretentious plant in care, it is enough to purchase a seedling or a 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 want to decorate the site and enjoy the taste of the Manchurian nut in the autumn should land according to the rules described below. It is worth considering when choosing a place that the plant belongs to light-loving, does not like acidic soil, 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 Manchu 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:

1. Digging a hole. We spread the upper soil separately from the lower one.
2. We drain the bottom with bricks, rubble, etc.
3. We mix the top and bottom soil, spread the mixture over the drain.
4. Clay or depleted soils must be fertilized. To do this, add humus, turf, sand 4/2/2/1 to the top of the soil in parts. Add potassium superphosphate in an amount of 20 grams (up to 40) and potassium fertilizer to the mixture. We put the resulting mixture over the drainage.
5. After a month, we dig a hole for the seedling.
6. Cut the central part of the root.
7. We pour out the excavated soil, but not all.
8. We put the seedling in the soil, check the level of the root collar with a wire or wooden stick. This part should be flush with the soil. You can also attach the seedling to a peg.
9. Fill with a bucket of water.
10. As the moisture is absorbed, lay out the rest of the soil.
11. We make a hole around the seedling.
12. Pour water - you need ½ bucket - a bucket.
13. We spread peat, sawdust or mature compost on top. Mulching will retain moisture.

It is very important to pay attention to the conformity of the root collar to the soil level. The parameter will avoid subsidence. Planting in a fresh hole that has not stood for a specified period of time can lead to improper formation of the root part. Root pruning helps the tree grow faster.

How to grow a Manchu nut from a seed

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

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

Kerosene treatment 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 during the month;
• second or third - twice;
• further - one.

After watering, the soil must be loosened, weeds must be removed. It is necessary to fertilize the soil in June; it is better to use potassium superphosphate for these purposes. In the spring, it is necessary to whitewash so that the trunk does not get burned in hot weather. Before winter, young trees should be covered with non-woven materials.

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

Growing a tree

To understand how to plant Manchurian nut seedlings at home, you should follow the recommendations of experienced gardeners. The walnut tree is a light-loving plant and should be planted in a well-lit area. For planting, you need to purchase seedlings and tools. The procedure is recommended to be carried out in September. How to plant a Manchu fruit - instructions:

1. Dig a hole about 90 cm deep.
2. Before planting a tree, drainage, rubble or broken brick must be laid at the bottom of the pit.
3. Plant the seedling in the hole and tie it to the peg.
4. Cover the hole with earth, pour water over it.
5. You need to complete the planting with mulching. For this, the soil near the seedling is treated with peat.This helps the seedlings grow without pests on the branches.

Growing must take place under acceptable conditions. With the onset of cold weather, the seedlings need to be insulated with a dense film. In the spring, the soil needs to be fertilized and saturated with useful minerals, this will help to grow a healthy tree.

Care

It is not difficult to grow a nut, since the plant does not need increased care.

After planting, care consists of regular irrigation, feeding, mulching, protection from frost and from parasites.

In addition, the plant should be protected from rodents. For this, a fine-mesh metal mesh is installed with a height of about a meter at a distance of 10-15 cm from the tree trunk. To prevent sunburn, the trunk is whitewashed or tall trees are planted nearby: linden, birch, beech, spruce.

Watering

Walnut trees have a high need for moisture, the plant is irrigated regularly and without stagnation of liquid. Under normal rainfall, an adult plant is irrigated 5 times per season, and young plants are irrigated twice as much. In a drought, irrigate every week for 15-20 liters. By autumn, watering is reduced, allowing the nut to prepare for winter.

Fertilizer selection and feeding

Once during the growing season (preferably in June), the nut is fertilized with phosphorus-potassium compounds. It can be fed in spring with nitrogenous fertilizers, and in winter with wood ash, which contains a set of macro- and microelements necessary for the normal development of the crop and obtaining a large harvest.

Mulching

Mulching allows you to retain moisture in the soil, insulate the roots from frost, protect from weeds and sunlight. It is advisable to mulch the Manchurian nut immediately after planting. Sawdust, peat, moss, hay are used as mulch.

To enhance the mulching effect, it is advisable to perform it immediately after feeding. When using organic matter, the mulch layer depends on the material: moss - 10 cm; sawdust - 7 cm; foliage or hay - 10-15 cm.

Preparing for winter

In autumn, you need to protect the trunk of a Manchurian nut from the approaching frost by wrapping it in felt, matting, burlap, agrofibre. For insulation, you can build a frame by filling it with sawdust from above or wrapping it with non-woven material.

Garden paint based on acrylic or latex will help increase frost resistance and protect against burns.

Pests and diseases

The Manchu walnut variety has good immunity, but diseases can affect the condition of the leaves, bark, and branches. Each disease has causes and progresses with its own characteristics:

• Black spot is a fungal disease that occurs in high humidity. It manifests itself in the fact that small dark spots form on the leaves of the plant. If untreated, a part of the crown of the Manchu nut dies off and the tree becomes weakened. For prevention and treatment, copper solutions are used.
• A tinder fungus that destroys wood, which causes the nut to dry out. Mushrooms must be cut and burned, and a solution of copper sulfate should be applied to the lesions.
• Nutcracker is a parasitic insect that infects the bark, leaves and flowers of the tree. You can get rid of the pest by cutting off the affected branches. When large areas are affected, they are sprayed with insecticides: decis, kinmix, carphobs.
• Bacterial burn is an infectious disease caused by a bacterium of the genus Erwinium. It is manifested by darkening and wilting of inflorescences, then leaves, young branches and bark are affected. They are treated with Bordeaux liquid and antibiotics.
• Gall-forming mite - affects leaf blades, deforms young shoots. To get rid of, they are sprayed with organophosphate compounds, neonicotinoids, pyrethroids. Severely affected branches are removed and burned.

When grown correctly, the Manchu nut develops rapidly and gives its first harvest a few years after planting. In addition to regular irrigation and the prevention of bacterial and fungal diseases, you should weed and loosen the soil around the trunk.

How to properly propagate a walnut tree?

It is not difficult to grow a young nut seedling - the culture is perfectly propagated by seeds, which remain viable for 3 years.

Preparation of nuts for sowing is carried out in 2 ways:

1. For sowing in the spring months, nuts are used, pre-stratified, aged until spring in a cold place. 10 days before planting, the nuts are soaked in warm water, which needs to be changed frequently.
2. There is a method of accelerated stratification of nuts, in which in the first decade of March the fruits are soaked in hot water for a day, after which they are placed in wet sand until seedlings appear.

Manchurian nut fruit
Planting nuts for culture propagation is allowed both in spring and autumn, but stronger trees are formed during spring planting.

Advice! Rodents love to dig up planted nuts and feast on them. To protect the planting material, you can treat the walnut shells with kerosene.

How to choose and store a Manchurian nut

If you have not yet grown this picturesque tree or shrub on the site and the opportunity has turned up to purchase its fruits, carefully examine it, it is unacceptable:

• heterogeneity of color;
• the presence of spots and darkening on the surface;
• rancid odor;
• the presence of moisture, traces of rot, mold.

These signs can serve as a reason for refusal to purchase.

You can store it unpeeled from the shell in a cool place with a temperature not exceeding 14 degrees Celsius for no more than a year. Over time, beneficial substances degrade and harmful ones are formed, therefore, the fruits of the plant that have been stored for too long should not be consumed. Conditions for kernels:

• in a cool place protected from direct sunlight - no more than 1 month;
• refrigerator - up to 6 months;
• freezer - up to 1 year.

Store in an airtight container to exclude the possibility of air ingress.

Use in the decoration 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 spreading, growing rapidly, therefore, within 1 year after planting, whole compositions can be made from young hazel. The culture is light-loving, so it is usually used as the highest part of the planting, or it is planted in front. It is not afraid of winds, so it is suitable for refining small hills and open areas that are not protected from gusts of air.

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

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

Brief summary

1. Manchurian walnut is unpretentious in care, and you can plant kernels or seedlings. Tolerance to frosts up to -48 degrees Celsius makes it possible to grow a plant in Siberia, the Leningrad region, central Russia and other regions.
2. A tree or shrub grows on all but acidic types of soil.
3. Shells, leaves, bark have healing properties. Decoctions are prepared to treat inflammation in the mouth or digestive disorders.
4. Pregnant women should only be taken with the permission of a doctor; nursing mothers should refrain from eating nuts so as not to cause an allergic reaction in the baby.
5. Do not give to children who are under three years old - the body has not yet synthesized enzymes for digesting nuts.
