| Pseudotsuga menziesii
DouglasfirCulture: The Douglas fir performs best in slightly acidic, well drained soils where there is an abundance of soil and atmospheric moisture, but is quite drought-resistant. The species transplants well, and prefers a sunny, open site. Principal enemies include: leaf casts, blights, witches broom, Douglas fir bark beetle, spruce budworm, Zimmerman pine moth, gypsy moth, and certain heart rots. The severity of these pests depends upon the region or locale involved. Usage: This species is excellent either as a single specimen plant or in groupings / massed plantings. It makes an excellent backdrop for planting beds, making yellows, whites, and pinks show particularly well. This species is cultivated as a Christmas tree because of its uniform habit and ability to hold on to its needles as it dries. |
