What month is over. When leaf fall near birch maple linden ends

This happens because, in addition to chlorophyll, there are other coloring substances in the leaves. It is especially plentiful at the end of September and the first decade of October. In what period does leaf fall of linden and birch begin and end?

With the onset of September, the trees gradually begin to replace the summer emerald green color of leaves with autumn yellow. By mid-September, birch leaves become ocher-gold and gradually begin to fall.

In many trees, leaf fall is uneven, that is, it happens at different times. For example, after the first severe freezing, leaf fall in linden and maples begins. By this time, birch has already dropped most of the leaves.

It is difficult to unequivocally answer the question when the time of leaf fall ends. It is noticed that at first they lose poplar leaves, then oaks and mountain ash. The dropping of leaves from trees serves another purpose - the crown under the snow cover has considerable weight. Tree branches, especially young ones, are not able to withstand such a load. Thanks to the process of photosynthesis, a large amount of harmful substances accumulate in the leaves by the beginning of autumn, which are removed along with the fallen leaves with the beginning of leaf fall.

Poplar During leaf fall, adult poplar trees lose a third of the leaves from September 15 to 20, in the first ten days of October up to 10% of foliage remains in the crown of poplar. Young poplars remain in a green outfit longer than old trees, they later turn yellow and drop leaves. Oak Oak leaves fall in the first half of September; after about 30 days, the trees completely lose their leaves.

Oak leaves immediately turn brown, along with leaves from the tree, ripened acorns fall. Mountain ash Autumn mountain ash is painted with watercolors, its leaves do not turn yellow, but acquire a pink color, the leaf fall process begins around the beginning of October, and ends by November 1.

Leaf fall of apple trees begins in the third decade of September and ends in the second half of October. Birch is a whole genus of deciduous shrubs and trees of the Birch family, which is common in almost the entire Northern Hemisphere. We are better known as a birch tree up to 45 meters high and a girth of up to one and a half meters.

Yes, many of us do not like this time of year due to constant rains and slush, but no doubt - early autumn is very beautiful due to the changing color of the trees. For example, the same birch tree begins to change color around the 20th of August, although this, of course, also depends on the weather.

However, we repeat, it all depends on the weather in the region. If for some reason the weather has changed so much that from the usual + 20 ° C the temperature has dropped to -5 ° C, then leaf fall begins almost immediately with the first frosts. The remains of leaves that can remain on trees even in the case of active leaf fall, as a rule, fall already after the third or fourth severe frosts and this applies to most trees.

Beautiful autumn forest when leaf fall begins. Forest glades dressed in yellow, and river valleys in wine red and pink. In the second half of September poplars also come in different colors: some of them turn lemon yellow, others become almost orange, and some become golden yellow.

By the end of September, even this strong, powerful tree obeys the general laws of nature - it becomes straw yellow. True, poplar and birch shed their leaves long before the general cooling. In aspen, leaf fall ends 5-6 days earlier than in birch. Old poplars are bare by a third by September 15–20, and by October 10 no more than 10–12% of the leaves remain on the trees.

September - the first signs of the coming autumn are already visible on the trees.

Apparently the matter is a combination of moisture, heat and daylight. Summer was very rainy and moderately warm. And by the middle of the month, forests are bare. In the Leningrad, Pskov and Novgorod regions, the end of the deciduous fall of birch and mountain ash is observed on average on October 14. In October, vertices, warblers, shrikes, corncrakes fly away from us. In the first days of the month, an average flight of geese was recorded in the Tver and Yaroslavl regions.

Their mass departure is observed in the Tver Region on October 18, in the Moscow Region on October 6, and in the Vladimir and Orel Regions on October 8–9. Starlings come to an end, as a rule, in the last decade of the month. For starlings mallard leaves for flight. Some birds remain with us for the winter. And not only rooks winter in our cities.

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.

The beginning of leaf fall. 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 1.4-4.

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.

By the time the leaf fall of the linden ends, the elm and bird cherry trees are completely bare. Their leaf fall ends at 2.

When leaf fall at birches ends. Birch is a whole genus of deciduous shrubs and trees of the Birch family, which is common in almost the entire Northern Hemisphere. Includes about a hundred species. Almost all parts of the plant are somehow used on the farm: birch bark, bark, wood and even juice.

We are better known as a birch tree up to 45 meters high and a girth of up to one and a half meters. However, in our country quite often there are also shrubs that barely rise above the ground. For Russia, birch is a cult tree. Remember how Sergei Yesenin himself loved him ....

Trees in autumn are very beautiful. Yes, many of us do not like this time of year due to constant rains and slush, but no doubt - early autumn is very beautiful due to the changing color of the trees. In fact, the color of the leaves begins to change a little earlier than September comes, that is, long before the first frost. For example, the same birch tree begins to change color around the 20th of August, although this, of course, also depends on the weather.

By the way, we often do not notice changes, since the color change occurs gradually and the first changes are visible only when the crown has become almost yellow. Birch leaf fall begins around the first half of September and lasts for another 20 days, that is, this tree completely falls by the end of September and mid-October.

A little earlier, aspen completely discards the foliage, and linden, poplar and oak are exposed after another 7-12 days. Together with a birch at the same time discards foliage and maple. However, we repeat, it all depends on the weather in the region. If for some reason the weather has changed so much that from the usual + 20 ° C the temperature has dropped to -5 ° C, then leaf fall begins almost immediately with the first frosts. The exception is only young trees of some species such as poplar.

The remains of leaves that can remain on trees even in the case of active leaf fall, as a rule, fall already after the third or fourth severe frosts and this applies to most trees. Well, finally, we remind you, dear readers, that several folk signs are connected with the birch at once, knowing which you can predict the weather for many months to come. So, if in the spring birch gives a lot of juice, then the summer will be rainy.

If a birch blossoms before an alder, then the summer will be dry, and then wet. Finally, if the foliage begins to turn yellow from the crown, then spring will be early, and if from below, then late.
