|I am searching for a screening evergreen that grows to 15 or 20 ft., nor more than 5 ft in width to cover 20 feet of fenceline. Technys are too wide and don't fill at the top. The top is most crucial. Do you have ay suggestions? Zone 4, suburban setting, plants will be adjacent to elegant 40ft white pine. Full to partial sun. Thank you|
|I think the best choice for the site is Pyramidal Arborvitae.
The pyramidal arborvitae is an evergreen tree with bright green foliage. Most pyramidal arborvitae can reach a height of fifteen to twenty-five feet and have a spread of about three to five feet. They make an excellent screen, and can grow at a rate of about one foot per year. When young, the pyramidal arborvitae has a bright green color to its foliage, which darkens as the plant ages.
A tall, slender and compact grower, the pyramidal arborvitae grows well in ordinary soil. They will grow equally well in both acidic and alkaline soil. Hardy in zones three through eight, the pyramidal arborvitae prefers full sun to thrive, but will work with partial shade as well. They will perform best in an area with high atmospheric moisture content.
Pyramidal arborvitaes make excellent hedge plants, as they grow fairly fast and have dense foliage that make good wind blocks for more delicate plants. Pyramidal arborvitae should be pruned early in the season, prior to new growth. This is often not needed, however, because the plants often grow naturally into a perfect pyramidal shape. If the winter is especially cold, the foliage of a pyramidal arborvitae will turn yellow-brown. The lush foliage of the pyramidal arborvitae makes it an attractive plant year round.
