Tree planting generally be gins in late April. Successful planting depends directly on natural ecological conditions. When nighttime tempera tures rise above +5°C, grasses, shrubs, and trees begin to sprout and bloom; this is a fundamental biological rule. Therefore, trees should be planted only once temperatures consistently remain above +5°C. Planting during freezing conditions will cause seedlings to fail and die. Planting in greenhouses is possible, as long as they are opened during the day and closed at night. Many people plant too early or too late because they are unaware of these conditions, which is why their trees often do not survive.
