Already in the first September days, the characteristic signs of the next season are clearly visible on the trees. They are inevitably impending autumn. Leaf fall for each type of tree occurs on time.
Leaf fall features
Watching the trees, you involuntarily start to think, and when does the leaf fall of linden, mountain ash, apple trees and other plants end? Leaf fall is a non-uniform phenomenon, its duration is calculated in several weeks. Colorful foliage in no hurry to leave the crown. Colorful leaves, as if reluctantly one after another, leave the branches.
Abundant fall of foliage occurs in late September and early October (until the first decade expires). Leaves caught in the third and subsequent frosts fall en masse. Thick leaf fall covers the earth with a colorful carpet.
Leaflets flying steeply gently fall to the ground, covering it with thick litter, which saves the rhizomes from freezing. Obliquely racing leaves play with bright autumn colors. And picked up by the gusty wind, plenty of work, find a safe haven.
Beginning of fall foliage
In autumn, the crowns of lindens begin to blaze long before the first frost. In the last days of August, single strands painted in grayish-yellow tones are visible among the branches. The proportion of colored leaves increases daily, the color palette becomes more intense. A noticeable gilding creeps on the crowns of the linden. And after 14-20 days, the foliage begins to burn in gold.
Birch trees by this time put on a buffy yellow outfit. Foliage of trembling aspen trees is being torn by kumach. Ash crowns shine with pale honey tones. Oak leaves are filled with brown colors. In the lace crowns of the mountain ash pink leaves shine. And the wild rose hives sparkle with a wine-red color scheme.
By the time the leaves of the linden fall, and this happens no earlier than September 23, the crowns of other trees are already being actively exposed. The first leaves of birches, aspen, maples and hazel showered on September 14th. Intensive leaf fall in limes is observed after the first frost penetrating the air, which usually happens on September 27.
First, lindens lose their leaves from large branches located below. Then the foliage crumbles from the middle of the crown. The crown of the lime is exposed last. In elms, ash and hazel, on the contrary, the upper branches are first exposed.
End of leaf fall
By October 7, lindens are losing their last leaves. At that moment, when the leaf fall of the linden ends, the weeping willows steamed with an alder still did not think to bare their dense crowns. Their leaves do not change color, they remain green until the first fluffy snow falls. Their foliage, seized by a strong frost, suddenly turns black. Crispy frozen leaves are difficult to stay on the branches, they quickly crumble to the ground.
By the time the leaf fall of the linden ends, the elm and bird cherry trees are completely bare. Their leaf fall ends on September 24th. Osinki are ahead of linden; their leaf fall is coming to an end on October 5. Birch trees, maples and hazel trees are in no hurry to part with foliage. A few leaves are kept on them until October 15.
Natural phenomena during the leaf fall of linden
The period of leaf fall of limes is accompanied by the arrival of cold fronts and night frosts. Cumulus clouds are replaced by a continuous veil and grayish haze. Flocks of birds flying south appear in the sky. After September 27, cranes in orderly schools stretch along the skies to the south.
And when the leaf fall of the linden ends, the half-naked crowns of other trees blaze with the brightest contrasting colors. Rooks, huddled in friendly flocks, fly away to warmer climes. Snow dust swirls in the air. Falling snowflakes do not yet fall to the ground, do not spoil its surface. Puddles twitch a thin ice. Skies of dirty grayish shades, devoid of clouds, turn into a gloomy rain film.
