Pine tree

What about it?

The pine tree is a large, narrowleaf evergreen tree with spirally arranged clusters of leaves. The fruit of the pine tree is a woody cone. The needles of the Austrian Pine are stiff and sharp-pointed when a cluster is pushed against the palm of the hand. They do not break easily when bent double. The leaves of the Eastern White Pine are slender and flexible.

What is it used for?

The pine tree can be used as an ornamental or for shade. It can also serve as a barrier, specimen, screen, windbreak, and lawn tree.

Where does it grow? How do we grow it?

The pine tree will tolerate somewhat poorly drained soils. It does best, however, in moist, well-drained, fertile soil.

When planting, pine trees should be spaced 50 feet apart, or 10-15 feet for a screen or windbreak

What are its primary problems?

Insects and diseases common to the pine include pine needle scale, diplodia tip blight, and white pine blister rust Some varieties of pine tree, such as the Eastern White Pine, are sensitive to air pollutants.
