Video: Boyko And Call About Woody Plants
On December 18, the second thematic evening of the Sad & Sadik magazine took place this season. The problems of planting and forming tree crops were discussed.
Tree and shrub groups form the basis of any landscape and are created for many years. Errors made can be difficult to correct, and sometimes impossible. We see them less in our garden, much more often in urban landscaping.
Our consultants on the "Green Line" receive a lot of calls on this topic, which indicates that gardeners are not well informed and that the topic has not been worked out very deeply in popular publications. Yes, and a full house in the hall of the Biological Museum. Timiryazev, where the meeting took place, testifies to the interest in these seemingly long-studied issues, not only from amateurs, but also among professionals.
Grigory Boyko, head of the arboretum of the Botanical Garden of Moscow State University. Lomonosov, shared with the audience in detail the technology of planting and placing plants in groups, developed as a result of many years of practice. By the way, the arboretum now has 1119 species and varieties of plants and is successfully replenished annually with 10-20 new forms, so the experience of its employees deserves the closest attention.
Let's extract a few recommendations for visitors to our portal - this approach is unlikely to appeal to landscape designers, but gardeners with a small budget will surely like it.
When choosing planting material, preference should be given to small specimens, they will be better able to realize their potential than large ones, already deformed for a different environment.
“Education should be started from childhood,” says Grigory Alexandrovich, “attaching great importance to the starting conditions for plant development. Then the adaptability of the plant is higher, and the formation will occur immediately under the appropriate conditions.
It is important to observe the optimal timing of planting and transplanting plants:
in spring - from the moment the soil thaws until May 10-15, for conifers - until May 1;
in autumn - until October 15, for conifers - from late August to September 20.
So the late fall conifer giveaways are best ignored.
Planting must be done in large planting holes: for trees at least 1x1 m, for shrubs 60x60cm, for vines twice as deep. All soil removed during the preparation of the planting pit must be improved and returned when planting in the hole. Of the fertilizers, it is not worth adding either potash or nitrogen to the planting mixture - they dissolve easily and burn the roots, but cannot yet be absorbed, they are quickly washed out of the soil and pollute the environment.
When planning tree and shrub groups, one must proceed from the size of the crown in an adult state, the need for light, moisture, decorativeness during the season. (Unfortunately, in modern catalogs there is often no information about the dimensions of adult plants, especially those that have recently appeared on the market.) There is no need to strive to plant large plants and compact plantings for the fastest achievement of a decorative effect, demonstrating a "furniture approach". This creates a competitive environment that does not allow to obtain copies worthy of admiring contemplation.
The second lecture , on shaping pruning of trees and shrubs, was delivered by Dmitry Zvonka, arborist at Treedoktor, Eurasian Arborists Association.
Not a lot of literature has been published on this topic, and it often suffers from a lack of specificity and confusion in terminology. Dmitry introduced the audience to the key points that can make the formation successful or, conversely, harm the plant. Much reasoning runs counter to traditional ideas, but is supported by a good knowledge of plant physiology and personal experience.
More information about this material can be found in No. 4 and No. 5 of the "Sad & Sadik" magazine for this year. Here are just a few tips for our gardeners:
- The formation of a tree begins already at the stage of its purchase - immediately try to choose a specimen that is “ideal” in structure. Any pruning will reduce the overall plant growth.
- The first formative pruning can only be done the next year after planting.
- Young trees (8-15 years old) tolerate pruning better - you can remove up to 30% (better up to 25%) of living branches with leaves; middle-aged plants can be subjected to crown correction - no more than 10% of branches are removed along the periphery; for old trees, only sanitary or safety pruning is acceptable.
- Avoid buying defective seedlings that require “compensatory pruning” to restore the balance between the underground and aboveground parts of the plant. It has been established that such pruning, on the contrary, inhibits root growth and impairs survival.
- To assess whether the tree is formed correctly, you need to move back a distance equal to its height. If the top is clearly visible, the shape is correct. And if there are protruding branches, they need to be cut off.
We are grateful to the editors of the Sad & Sadik magazine and the editor-in-chief Rosa Shornikova for this meeting, for the opportunity to receive scientifically grounded recommendations from leading experts.
Look for information about the next events of the "Garden & Sadik" magazine in the "Exhibitions" section of our portal GreenInfo.ru
Until next time!
