The anatomy of a oak tree

The oak tree blooms (第三人称单数加S ) in the spring. It is 600 years old and experiences a sustainable blooming period. Majestic and towering, oak trees are valued for their wood, appearance, fruit and importance to wildlife. The experts tell us that Oak trees do not start blooming and producing acorns until they are around 20 years of age, according to the University of Tennessee Extension Service. Oak trees produce the most flowers and acorns between the ages of 50 and 80. So let us figure out why it is so blooming after six hundred years.

Firstly, oak trees produce both male and female flowers, which means they self-pollinate. The male flowers hang in showy, long, yellowish-green clusters called catkins. They produce a lot of

pollen, which clouds the air in mid-April and makes those who have tree allergies rather miserable. The female flowers are much more inconspicuous. They appear about a week after the male flowers. Nestled against the base of twigs, they look much like tiny leaf buds and are hard to see. Look at the picture of the oak tree, it has tens of thousands of female flowers which make

it have many acorns.

Besides the female flowers, Weather plays an important role on the quality of an acorn crop. Wet weather and humid conditions will prevent pollen from spreading well. This results in less acorn

production. In most cases, it takes only one year for white acorns to mature. If an oak tree becomes stressed from environmental conditions or disease, it may not produce any acorns at all for a season or two while it regains its energy and health. The strong trunks provide it with energy.

regions with a Mediterranean climate – dry summers and wet winters, ensure the oak tree adapted in the best climate. And the enough space and drained soil also create great situations for the oak tree. All these make it clear that the oak tree is blooming in his 600 ages.
