The color of the bark is closer to dark gray, but the tint of the shoots is more brown. Under natural conditions, the height of adult culture can reach 30 m, and life expectancy is long - up to 200-250 years. In this case, the active growth of the tree lasts only up to 80-90 years, after which the process slows down.

The leaves of the Manchurian walnut are characterized by a rather large size, in contrast to the closest relative - walnut. It is interesting that one leaf consists of 8-20 oblong and smaller leaves with jagged edges. On average, the total length is about 50 cm, but there are specimens with sizes reaching 100 cm. In the summer, the foliage has a rich emerald color, and by the autumn it acquires a golden hue.

At 10-12 years old, the plant begins to bear fruit. At the same time flowering occurs in April-May, but the harvest of fruits can be collected only at the end of summer - beginning of autumn. As for the appearance, the shape of the nuts resembles an oval, and the size is about 3-5 cm in diameter. Grow clusters of 2-7 fruits on a branch. It should be noted that the Manchurian nut shell is durable, and the thickness reaches 5 mm.

Rules of planting and growing in the Urals

Since the Manchurian nut is distinguished by unpretentiousness, it is realistic to plant and grow in almost any conditions. In addition, designers often use it in landscape design. This can be done by planting seedlings or seeds.

Planting a Manchurian seedling or seed is possible both in autumn and spring. In this case, the best option would be April or September.

Each growing method requires paying attention to 2 important points.

  1. The choice of location. Culture belongs to the light-loving plants, so the habitat must be open and sunny. And since the root system of the Manchurian nut grows deeply and widely, you should choose a site far from buildings and other garden crops.
  2. The composition of the soil. The soil should be fertile, well drained.

With regard to the process of planting, here each method involves its own nuances.

Planting seedlings:

  1. Seedlings should be purchased in advance at a specialty store.
  2. If the soil is rather poor, a mixture of soil, humus, sod and sand should be prepared in a ratio of 4: 2: 2: 1. At the bottom of the hole lay out the drainage in the form of brick fragments or gravel, crushed stone.
  3. A part of the soil mixture fits into a well prepared in advance, not less than 80 cm in size. Potassium fertilizer is introduced or 1 cup of wood ash. The seedling is placed in the hole and immediately tied to the peg, and then powdered with planting mixture. After that a bucket of water is poured into the hole and the remaining soil is poured. Further, the sapling again spills 0.5-1 liters of water.

Planting seeds is somewhat different from the cultivation of seedlings and suggests its own characteristics. It is worthwhile to clarify here that it is preferable to land at winter, in other words, in September. In this case, preliminary stratification of seeds will not be required, and seedlings will appear much earlier.

There are the following stages of planting seeds:

  1. For planting should choose nuts collected no more than 3 years ago, since the third year, germination is significantly reduced.
  2. The soil for sowing should be fertile, drained. The site should be pre-dig and make 2-3 cups of wood ash. Then you need to form a bed and carefully shed it.
  3. Seed wells are prepared at least 8 cm apart. The depth of the pits should be 6-8 cm.
  4. Nuts are laid in the hole on the edge and sprinkled with earth.
  5. Shoots nuts can immediately move to a permanent place, but you should first pinch the taproot. It is not forbidden to leave the seedlings in place for another year, and then transplanted to the prepared area.
Before sowing, each nut should be dipped in kerosene. This will save the seeds from the encroachments of mice and other rodents.

Rules of care in the suburbs

Immediately after planting a sapling or a walnut fruit, the soil will need to be mulched with sawdust, peat, and healthy foliage. Of course, the bed should be carefully watered beforehand and subsequently also maintain humidity.

If the planting was done in the fall, before the cold, young seedlings will need to wrap with non-woven material and cover with a protective net from rodents.

Further care of the young plant includes the following points:

  1. Weekly watering plants. After 2-3 years, the frequency of irrigation should be reduced to 2 times a month. Since the third year, the walnut is watered 1 time in 30 days.
  2. Regular weeding, loosening and mulching the soil around the seedling to maintain moisture.
  3. In the second half of summer, the culture must be fertilized with fertilizer. Here, the best option would be superphosphate. It will be necessary to dilute 20 g of the substance in 10 liters of water and water the soil around the plant with it.
  4. In order to avoid sunburn, plant stem should be whitened regularly with a solution of lime and clay.
Every year, in the beginning of spring, frozen, damaged and diseased branches should be removed from a walnut tree. The air temperature at the same time should correspond to the mark of + 10 ° C.

Diseases and pests

Manchurian walnut is resistant to disease. But there are exceptions.

It is possible to distinguish the following possible diseases of the nut:

  1. Fungal diseases. A sign here is the drying and blackening of the leaves. As a treatment, the plant will need to be sprayed with Fundazole or another agent containing copper. The procedure is repeated after 2 weeks.
  2. Gall mite. Females lay eggs in the central part of the leaves, which is why they form characteristic tubercles. The plant should be treated with colloidal sulfur diluted in 10 liters of water at the time of bud break. From the beginning of summer, you can spray Fufanon every 10 days. Branches heavily damaged by ticks must be removed and burned.
  3. Nutcracker This insect infects the bark, leaves and buds of the nut. The best method of struggle is pruning damaged areas of the plant. But if adults emerged from the larvae, the plant should be treated with chlorophos (0.2%) or karbofos (90 g per 10 liters of water).

In general, the unique antimicrobial properties of the culture allow the plant to protect itself from the attacks of harmful organisms.

The healing properties, taste, and the attractive beauty of the Manchurian walnut make it increasingly necessary to pay attention to the unusual culture. And the ease of planting, as well as ease of further care, determine the popularity of plants among experienced gardeners and beginners.
