Older trees are of much greater value than young and small trees, because functions, the trees' fullness is usually proportional to their size. The need for planting large ones, older trees is felt particularly strongly in newly built housing estates and other new parts of cities. Planting such trees, however, cannot be mass-produced, mainly due to the considerable cost and the lack of appropriate nurseries at present. The cost of transplanting a tree with a trunk diameter of approx 20 cm can be 30-50 times the cost of planting a young tree. For these reasons, the planting of older trees is limited to necessary situations and justified by various reasons. There are many such situations nowadays due to the widening of streets, allocating land for development, etc.. The transplanting operation is less costly, if the trees are only to be moved a short distance.
In addition to considering economic considerations, which are usually decided by the client, the suitability of individual trees for transplanting operations is also assessed. Decisions on this matter are always the responsibility of garden specialists and are made on the basis of an analysis of many different factors, to which it belongs: tree species, overall plastic value and health, age and sizes, projected weight, technical conditions of transport and care conditions.
Tree species. Each tree species has a specific ability to regenerate the root system and adapt to new conditions. This ability usually declines with age, however there are trees, who tolerate transplantation relatively easily in their teens, and even several dozen years. These include, for example. linden trees, maples and ash trees. Birches are among the trees that are more difficult to transplant, chestnut trees, nuts and others. However, in later age, most conifers, as well as willows and poplars, are generally not transplanted.
