Pine trees are rapid-growing, evergreen coniferous trees that are part of the Pinus genus in the Pinaceae family. Approximately 115 different species of pine trees exist. Pine trees are commonly used for the production of wood pulp and timber. The trees are one of the most well-known ornamental plants on earth and are also commonly used as privacy trees or to function as noise barriers.
Pine trees are capable of growing in any soil type and on any part of the planet. There are no restrictions geographically for cultivation of pine trees. Also, they are the sole variety of trees that is able to reproduce via seeds within a cone. As a result of their ease of cultivation, the trees are extremely diverse and popular.
Great Basin Bristlecone Pine
The Great Basin bristlecone pine is known scientifically as Pinus longaeva. It is one of the planet's oldest surviving trees. The pine trees appear in areas of high elevation in the southwestern region of the United States. One Great Basin bristlecone pine tree is known as Methuselah and is almost 5,000 years old. The tree is in Bishop, California.
Southern Pine Bark Beetle
As with most trees, there are various pests that could attack pine trees. One notoriously devastating example is the southern pine bark beetle, which primarily attacks pine trees that grow slowly and are densely-stocked. Thousands of these beetles are able to simultaneously attack one pine tree, making them extremely destructive and dangerous.
Apart from pests, there are also various diseases that commonly affect pine trees. The most common pine tree diseases include armillaria root fungal disease, diplodia blight, butt rot and annosus root disease.
It does not take much to keep a fully grown pine tree alive and healthy. Once a pine tree is completely grown, it needs very low amounts of water. However, the trees require full sun for optimal health and to stay alive. Also, pine trees flourish when grown in soil that is acidic and sandy. Some pine trees also do well in soil that is calcareous. Well-drained soil is necessary.
