“Forests are dressed in crimson and gold,” the poet said about autumn, one of the most picturesque seasons in nature. Only autumn fills the world with such unusual, generous, juicy colors. Leaves of birch in the fall become yellow, aspen and maple - red, oak - yellow-brown, and mountain ash - reddish-yellow. This then the trees and shrubs will lose foliage, which will fall and cover the ground for the winter, protecting the roots and animals living in the ground from frost. And first, the summer day will become shorter, the night will be cooler and the leaves, more recently so green, will increasingly lack heat and light.
Birch is an unpretentious deciduous deciduous tree plant that is common in Russian open spaces and belongs to the birch family. Its various species are common from the Arctic Circle to the tropics. The warty (or dangling) birch habitual for us can reach 45 meters in height and up to one and a half meters in girth.
And in order to answer the question: “When does the fall of leaves near birches end?”, First we’ll find out some points.
Why does the tree need leaf fall?
Everything in nature is arranged wisely. Trees need leaf fall in order to successfully winter and be reborn in the spring. In September, with an increase in cool and cloudy days, nature makes it clear to the tree that autumn is coming, so the sap flow, that is, movement along the trunk from the root system to the foliage and back of nutrients, slows down. Birch leaves first lose their summer emerald brightness, and then turn yellow.
Sap flow, by the way, is especially intense in the tree trunk in spring. Minerals dissolved in water rise up from the roots, and organic substances go down from the leaves down the bast. It is in the spring that birch sap, so beloved by many, is extracted from birch trunks. It is very useful and contains a large number of vitamins, organic acids, sugars and even essential oils.
Usually by October, when the fall of leaves near birches ends, the nutrients necessary for the plant to winter are already accumulating in the roots, the sap flow slows down and stops altogether by winter.
A tree needs leaf fall and in order to save and store moisture for the winter, which is constantly and quite a lot of leaves (conifers, as you know, because of the small size of their leaves, needles, as you know, they do not dump). In addition, in winter, under the weight of the fallen snow, tree branches can break, and this heaviness would be much greater if the snow fell on branches with unflown leaves.
But if you pick a branch with leaves at the beginning of autumn and put houses in the water, eventually the leaves will fall off. Why? This fact tells us that leaf fall is inherent in the nature of the plant and is part of its life cycle.
When does leaf fall at birches end?
Together with aspens, they are one of the first to begin to lose foliage. And to say for sure when the leaf fall at the birches ends, like any tree at all, no one can. There are only approximate, average terms.
Birch begins to drop foliage in the first ten days of September. This can continue for 20 days. The end of fall foliage by the birch will come approximately at the beginning of October, and by the middle of the month the trees will already stand bare. After the first frosts (they occur around the end of September), leaf fall is more intense.
What determines the leaf fall time?
This is due to several factors: the type of tree, its age and climate of a particular area.
As mentioned above, birch is one of the first to drop leaves. A young tree stays green longer and later turns yellow.
The farther south the place where the birch grows, the later the color of its foliage will change. For example, in the northern regions, it begins to turn yellow in August.
In warm and sunny autumn trees will be "dressed" longer.
In the end, let us recall one of the folk signs about leaf fall by birch. If the foliage of the tree begins to turn yellow in the autumn from the crown, then spring will come ahead of schedule, but if the lower layer of the deciduous crown turns yellow first, then late.
