Three-story trees are an amazing invention!
Do you know what summer residents regret, for whom their hobby has become the meaning of life? They are tormented by the problem that there is not enough land on which they can plant whatever they want. And I want to grow a lot of things. So today, a method for obtaining many different varieties of fruits from a small area has already been discovered! In addition, thanks to this technology, it is easy to grow crops that, due to their low winter hardiness, did not take root earlier in the middle lane. How to do it?
Have you heard about three-story trees?
No, we're not talking about tall giant plants. The floors in our case are fruit varieties arranged in rows on the same tree. However, in order to implement this, you will need to be vaccinated. And this procedure requires certain skills, diligence and time.
But thanks to her, you can reduce the number of trees on your site. And to get, meanwhile, a greater number of various fruit crops, 5, 10, or even 15 different varieties and even species from one plant!
V.I.Susov's discovery
In addition to the fact that different varieties are obtained from the same tree, saving planting space, grafting can allow you to get the fruits of a culture that previously did not survive in the middle lane due to low winter temperatures. For this, it is recommended to place a low-winter variety on the second floor. And now even peaches and southern apricots bear fruit perfectly on our plum, which is familiar to frost.
In principle, a highly resistant apple tree and previously grafted thermophilic varieties. What kind of super useful discovery are we talking about then? But what about!
V.I.Susov, Honored Agronomist of Russia, Leading Researcher of the Moscow Agricultural Academy and Candidate of Agricultural Sciences, has been working on one problem for many years. And it was that after grafting heat-loving varieties on a winter-hardy rootstock, the tree bore fruit for 15 years at most. And then the effect of increased resistance to low temperatures came to naught. Not only did the grafted branches perish, the whole tree perished.
And so Vladimir Ivanovich Susov experimentally made a discovery that we can use today without hindrance so that our thermophilic varieties bear fruit for as many years as the mother tree itself will live. How can this be achieved? Here's a step-by-step guide to making your discovery a reality.
How to grow three-story trees?
"Growing three-story seedlings with stem and crown formers" - this is the name of the work of the scientist agronomist V. I. Susov, who made a real breakthrough in the process grafting trees and shrubs. This process is long, but the result speaks for itself.
- First grown winter-hardy seedling... Susov calls it the first floor. It is grown for 2-3 years, carefully forming a good, "correct" crown. That is, it is important that the angles of departure of the skeletal branches from the trunk are 70-90 degrees.
- Then, at a height of one and a half meters, a high-value variety or breed is grafted onto it. This scion may already have low winter hardiness. This is the so-called second floor, which is called a strainer by an agronomist.
- After the results of the vaccination show that it was successful, you can start forming the third, crown-forming floor. It is placed on a scion at a height of 2.5 meters from the ground. Vaccination is done with another winter-hardy variety.
An excellent result of this discovery is based on the fact that the winter hardiness of trees directly depends on its crown. If the culture has only two floors, and the scion of the thermophilic variety is at the very top, being a crown former, then, as mentioned above, in 12-15 years the whole tree will become as thermophilic as the scion itself.
It is important to ensure that the crown of three-story trees is always well lit. The second important condition for an excellent result is its small size. That is, the crown of such trees should not be wider than 3.5 meters.
