| Pinus nigra
Austrian pineCulture: A very adaptable species, this tree withstands urban conditions better than most other pines. It can tolerate a wide range of soil types, including heavy and light soils, it resists heat and drought, and is tolerant of salt spray. These cultural adaptabilities combined with its dark green color and uniform pyramidal habit in youth, have led to its widespread use. This species can be severely affected by Diplodia tip blight, which can kill or disfigure mature trees. The blight causes the needles at the tips of branches to turn brown and the buds to exude excessive amounts of resin. Shoot growth is stunted and twigs may die back with this disease. Unless you are willing to apply annual preventative fungicides, this species should not be planted in large numbers. Although much less sensitive than Pinus sylvestris, this species is also susceptible to pine wilt nematode. Usage: The uniform habit and dark green winter color has led to this species being most often used as a specimen or screening plant. Its dark green color makes an excellent backdrop for smaller flowering trees and colorful shrubs and flowerbeds. The Austrian pine is only a short-term choice for a windbreak, as the tree looses its lower branches as it ages. |
