Southerners AWAY

In recent years, some previously considered purely southern culture moved far to the north.

Among them — persimmon, apricot, peach, cherry and walnut. Attempts to expand the range of growth last taken at different times, both scholars and enthusiastic gardeners.

Almost 30 years experimenting with walnut dedicated professor A.K.Skvortsov. In 1977 he laid the first experimental plantation, which became the basis for the seedlings grown from the fruit trees growing in the Moscow enterprise «Experimental Plant NIUF.» Later they were joined by plants from other places. Over the years of plantings were closely monitored, but the final conclusion that A.K.Skvortsov announced in 2005, was disappointing. In one of his articles he wrote: «With regard to the climate of Moscow is not detected any significant features that distinguish to plants grown from seeds of different parties … For the stability they depend, obviously, more of the situation and of the coincidence during the life of each wood than on its genotype. This should be expected because the genetic potential of species adaptation to more severe climatic conditions have long been practically exhausted. This is particularly evident in the reproduction of our plants: they have not proved to be more resilient than their parents. «

In the metropolitan area can be found a significant number of walnut trees. One of them grows quite close to Moscow, in Shcherbinka. It has been cultivated about 22 years ago, walnut brought from Donetsk region. Wood from the wall of the house covered with the winds and receives additional heat, not frosted over and gives albeit too small, but tasty and tonkokorye fruit.

Another of the walnut trees, brought seedlings Rostov-on-Don, grows in a holiday village at Khimki. From the north it reliably protect the house and a large oak tree. Each year, the host collects trees with a bucket of nuts.

A gardener for the Moscow Region A.Bukina walnut production has long turned into the most mundane activity. Its seedlings from Leninsky district, he repeatedly demonstrated at various trade shows.

There are some instances of fruiting walnut in Kratovo, Kolomna, Ruza and other settlements near Moscow. Also, I know of two trees derived from the Baltic and nuts growing in the apothecary gardens (Botanical Garden of Moscow State University, Moscow), as well as a single copy in the district Novogireevo (east of Moscow).

Probably, the most northern of the walnut plantation was founded in the reference section of the Leningrad Botanical Garden is located 100 kilometers north of the city, on the Karelian Isthmus, in the village. Gratifying. There’s the introduction of this plant since the beginning of the 50s dealt a botanist I.N.Konovalov. On the results of those experiments, big science is silent, but in the Botanical Garden of St. Petersburg grow and live the trees grown from the fruit of the walnut selection Konovalov. However, in bad years due to the lack of heat in the fruits ripen them.

There are in St. Petersburg for at least another two walnut tree. One of them — on the street. Esenina, growing in a strong thickening and looks depressed, although the affliction and fruits. But the second-on the seaside promenade — feels very good. His more than 20 years ago I planted a gardeners Valeriy Yevtushenko seedling brought from Rostov. For the second decade tree produces abundant harvests. According to the owner, nuts is sometimes more than two hundred of the season.

Until now, it was about ordinary nuts, which are beginning to bear fruit in ten years after planting. But our colleague Valery Goryachev of Krasnoarmeysk Moscow region managed to grow early appearance of fruit dwarf hybrid walnut breeding I.Levina. This walnut gave the first harvest in 4 years .If this your seedling grower does not harbor.

As you can see, the walnut is not so rare in the middle lane, but not very stable — often freezes and remains without a crop.

Nevertheless, his forces grow most gardeners. The main thing is to create favorable conditions for the nut — to ensure a sunny location protected from strong cold winds. Most of the plants I’ve ever seen are in such conditions, under the cover of trees, fences or buildings.

Although Professor A. K.Skvortsov argued that the walnut plants from different regions differ little among themselves on sustainability, it seems to me important is where to get the planting material. For example, I have a seedling grown from the Crimean nuts, even under snow annually frosting almost to the ground, and seedlings obtained from the suburban and Kharkov plants, most of them last winter if not noticed.

So, in my view, walnut, albeit with some reservations, it can be grown in regions with southern climate is not.
