Time to plant trees.
The trees can be planted at different times, but the conditions are not always conducive to the establishment of these plants. The planted tree should be in a physiological condition favorable for transplanting, and at the same time there should be favorable weather and soil conditions.
The conditions conducive to planting trees are considered to be: state of rest, no leaves (in deciduous), as large root system as possible and sufficient water saturation of the plants. Conditions that are not conducive to the acceptance of the planted plants are: ongoing vegetation, persistent leaves, overdrying, too large a crown in relation to a significantly reduced root system. The external conditions favoring planting are: low but positive temperatures, high air humidity and moderate soil moisture, appreciation, no wind. Much worse conditions exist, when there is high temperature and low air and soil humidity, strong sunlight and winds.
If trees are planted in bad condition or during unfavorable weather conditions, these plants should be properly nurtured to facilitate their adoption, like watering, shading, covering the soil surface, etc..
The best time to plant deciduous trees is in the fall from mid-October to mid-November. These trees are planted first, which ended the growing season. The end of this period is marked by discoloration and falling leaves. Often, plants are also kicked out of the nursery before the leaves fall, and then they are removed mechanically. However, this can only be done with these trees, which already have sufficiently lignified young shoots. Earlier digging from the nursery and planting it only to avoid work accumulation in the short term, but it also offers a greater chance of planted trees rooting well before winter. The results of early autumn planting are all the better, the more favorable the weather conditions at this time. Trees planted too late in fall cannot take root sufficiently before the onset of freezing temperatures. Such trees may be at risk of dying out due to drying out, because they are losing water continuously. This is favored by low air humidity during the occurrence of negative temperatures. If the soil freezes under these conditions, it becomes impossible to draw water, which leads to drying out. Late planted trees, therefore not sufficiently rooted, the period of root regeneration and water uptake can be extended by preventing the soil around the tree from freezing. This is best done by a thick layer of leaves, peat or similar material. If there are no such materials, a mound of height should be built around the trunk for the winter period 30 cm. Trees should not be planted after frost has occurred. Trees that have not been planted by that time should be pitched in a sheltered place, water well and protect the soil covering the roots against freezing.
Planting deciduous trees in spring is less often recommended. The length of the spring planting period depends primarily on weather conditions. In our climatic conditions, this period lasts from the beginning of April to the first days of May. The high temperatures that occur at the end of this period are very disadvantageous, which for insufficiently rooted trees are more dangerous than negative autumn temperatures. In many cases it forces planted trees to be watered, mulching the soil surface and other additional treatments. The performance of these activities is often hindered by the accumulation of many gardening works in spring. Therefore, in the spring time, trees should be planted only in heavier and wetter soils, which gives them a greater chance of admission without the need for additional beauty treatments.
However, some deciduous tree species should be planted in the spring. They are species that end their vegetation late and start it late. These include beeches (Fagus), oaks (Quercus), hornbeams (Carpinus), nuts (Juglans), triiglic (Gleditsia), robinie (Robinia) in inside. Birches are also planted in the spring (Betula) in the phase of stimulated vegetation, poplar (Populus) and willow trees (Salix), and these tree species, which in our climatic conditions are not completely resistant to frost.
Conifers are usually planted from mid-August to mid-September or in spring with signs of stimulated vegetation., usually from mid-April to mid-May.
