Hot time in nature. With full dedication "work" all organs of birch trees,
which are combined into a complex system of life support, and storage of
extremely useful substances in its innermost coffers, to provide with them
its buds, and give them to us, during the spring.
The accumulated nutrients are spent on the development of the branches of
the tree roots, increasing the "pantries", where they can add sugar
developed by leaves.
Sugar is generated by the sun and chlorophyll, which is contained in the
leaves - this sticky green substance, which gives a color to leaves and
because of which trees are called "green lungs of the planet Earth".
Chlorophyll is producing only under sunlight. The process itself represents
absorption of carbon dioxide from the air and water from the root system,
which is located under the ground. As a result, the tree produces sugar -
this universal nutrient product.
It should have time to do more reserves. After all, autumn will come soon.
Autumn time - time of preparation for winter. Plants are prepared for the
winter sleep to gain forces to rapid growth in spring.
With the advent of autumn, the duration of daylight is decreasing. Tree
produces less nutrients, slowing down all its processes.
The chlorophyll begins to collapse, and green color in the leaves
decreasing. There comes a time of other pigments: yellow xanthophyll,
carotene, orange and red anthocyanin. Because of these pigments leaves
obtain a bright color. Along with green color of leaves go, and
carbohydrates. They are moving in the winter, "pantries", which will be
partially converted before spring. After leaf fall wood is very is rich
with starch, and fallen leaves do not contain it almost completely.
The process leave-fall begins in the summer. At the bottom there is a
special cork layer generating. It has a smooth wall, which can easily be
separated from each other. When the cells of the layer begin to collapse,
then we can talk about the beginning of leaf fall. Slowly whirling leaves
of all colors and shades covers the ground with a beautiful carpet. The
leaves are falling, and creating a new cork layer, ready to become the
basis for the formation of new leaves at spring.
Tree is preparing itself for winter.
At winter birch trees are asleep and store energy in order to rush into new growth with the onset of warmer days. At the cold weather intensively developing so-called formative tissue (meristem), from which eventually rise new birch cells and tissues, happens laying of rudiments of leaves.
The tree rid of excess moisture. Starch partially converted to sugar, partially in a fat, oily liquid. It is reserve for the cruelest cold.
Carpet from dropped leafs is also priceless. And not only because there is a lot of carbohydrates in fallen leaves. They contain plenty of mineral substances, such as potassium, phosphorus, calcium, nitrogenous substances and microelements useful. It is a unique and irreplaceable fertilizer for the soil. But, first of all, fallen leaves acts as covers. Some sort of a sponge, performing wide complex of tasks. Leaf cover regulates the moisture of the soil, prevents erosion and soil crusting after rains. It reduces soil thermal conductivity and covers it to protect tree roots from freezing.
Everything here is reasonable, appropriate and functional. After all, it’s necessary to wait until spring.
Spring. It has been almost no frosts. Day becomes longer. It's time to grow
up. Birch has been ready for it since the middle of the winter. It is
necessary to have time to quickly grow up new leaves and branches and have
time to make enough reserves for next winter and become even stronger.
From the roots to the crown began movement of birch sap, which absorbed
autumn reserves of nutrients and mineral salts, trace elements and vitamins
from spring watering of the root system.
The palette of medicinal components in the spring sap are extremely
versatile: everything that rich Bukovynian land reserved, everything which
native environment generously shares with us , which is incorporated in the
natural reserves of rich and generous native land, transports to young tree
Exactly in this moment we're going to have this sweet, magical,
transparent, nutritious, useful birch sap.
Nature let us to collect birch sap for less than a month. We must hurry to
make reserves for the whole year. Time is inexorably moving on. Powerful
vivifying flow of spring sap passes relentlessly quick. We must to collect
it in time before leafing. It’s necessary to be ready for work. Otherwise
juice becomes unclear and not so sweet.
