Introducing Oak Tree – Oak Tree

Oak Quercus belongs to the Fagaceae family. In this family, about 600 species have been identified which, despite their apparent differences, are known as oak names. Native oaks from temperate to tropical regions have different parts in northern windmills, and have oily or deciduous species. The leaves of some oaks have a slight margin and some others are lobed.

In the spring, male and female flowers are formed in separate form, and their beautiful fruits are formed, which, of course, takes 18-6 months to reach the fruit and can be harvested. Oak roots grow well under the soil so that they can meet the need for water and food of these stout and tall trees. For example, the roots of an elongated and elongated oak can well extend well below the ground up to a distance of about 12 meters from the plant and more. Oak trees are basically a long life, and today there are old oak trees that have been estimated to last about 800 years.

Introducing several species of oak

Oak has a very varied species, some of which are most commonly used

Northern Red Oak is known as the Quercus rubra, known as the Red Oak, which grows fairly fast, increasing annually by about 60 centimeters to its height. Preferably the soils that are slightly acidic are preferred, and in such soils late in the growing season, the leaves are red in the autumn, so it is known as the red oak. It has good cold tolerance and can tolerate cold temperatures of -30-35 ° C in winter

Holly Oak, known as the Quercus ilex scientific name, is an evergreen oak tree, with stretched leaves with a flat margin. One of the most interesting issues with this oak is that it can be grown as a shrub, and since It’s very good to be pruned. Using a sharp pruning action, you can also use it in the form of a hedge

The White Oak is known as the Quercus alba, known as the White Oak. It is about 30 meters high and young leaves of this colorful plant have a very pale pinkish color, and are not initially green, gradually growing green, and therefore known as white oak. This type of oak also prefers the soils that are slightly acidic, and in winter it tolerates air temperatures of -25 ° to -29 ° C.

Common Oak with the name Quercus robur, commonly known as Oak, is one of the most popular and most popular oak types that can be found at a height of 30 meters.

Note: Various samples have been obtained through the two-way method between different species of oak to this day

Environmental conditions

Irrigation: Oak trees generally require enough water to grow best. For example, a tree that is about 20 meters high, when the temperature is about 32, loses about 90 gallons of water, and the water should be as much as possible. To continue to live. Therefore, these trees are found in nature where the amount of ascendants is sufficient to meet their moisture needs, or if they have to provide this moisture with irrigation. Note that due to the spread and distribution of the roots of this plant around the main trunk, the soil moisture should be able to grow anywhere from 40 to 30 cm deep, but irrigation of a small area around the trunk does not work to optimally grow the plant. In other words, if, for example, the moisture requirements of fruit trees can be met by drip irrigation, but for oak trees this method is not feasible and it does not get any good. According to this description, it would be better if you do not plant the plant if you live in a place where there is basically damp weather and wet all soil around the trunk, especially in the summer.

Light: The oak tree must be planted somewhere to get from 8 to 6 hours of direct sunlight. The lack of light primarily prevents the formation of flowers, or causes the flower to fall, and ultimately reduces or does not fruit the plant. Also in low light conditions, the incidence of fungal diseases may increase. Oak trees, on the other hand, do not have a problem with the full amount of sunlight until they have the water they want. That is, if the planting site has sunlight for long hours and the weather is warm and dry and the plant is dry, the result is burning the margins of the leaves, the shrinkage and burning of new and young leaves, or their lack of growth, and eventually the early fall of this tree. .

Temperature: Tolerance of oak trees against cold in different types of plants is somewhat different. Some species tolerate cold weather up to -30 ° C without any problem, but there are also types that tolerate the cold by about 12 ° C, and the lower temperature initially destroys the plant’s young shoots and In the event of a colder environment, the plant’s stems and branches will disappear and dangerous cracks will appear on the main body of the plant.

Soil: Oak accept a wide variety of soil, but some are grown on slightly acidic soils and somewhat more commonly used soils, for example, red oaks grow if they are planted in soils with normal acidity but grow on soils that are acidic. And in the autumn, their leaves are red in color, creating a stunning view. On the other hand, it’s basically soils that have very heavy texture
