General Culture:
Best grown in average, medium wet, well-drained soil in full sun to part shade. Prefers sun-dappled part shade and moist, sandy loams with a slightly acidic to slightly alkaline pH. Tolerant of pruning and shearing. Avoid cultivating around plants because they have shallow roots. Roots appreciate a good mulch (1-2 "). Thin plants and remove dead/damaged branches annually to improve air circulation. In USDA Zones 5 and 6, this boxwood is best sited in a sheltered location which protects it in winter from strong winds and full sun. Carefully remove heavy snow accumulations as quickly as practicable to minimize stem/branch damage.
Noteworthy Characteristics:
Fastagiata is a narrow conical form of English boxwood which will eventually grow to 12 tall and 5 wide unless pruned shorter. Habit is more tree-like than most other boxwoods. Elliptic to oval, dark blue-green, evergreen leaves. Flowers are inconspicuous. Sempervirens in Latin means "always green". Fastigiate means "upward branching".
Boxwoods can be somewhat temperamental plants to grow in the St. Louis area where the evergreen foliage tends to bronze (turn unattractive brownish-yellow) in harsh winters, particularly if plants are located in open areas exposed to full sun and winter winds. Otherwise requires little special care other than annual pruning. No serious insect or disease problems. Some susceptibility to blights and leaf spot. Root rot can also be a problem in poorly drained soils. The three main insect pests of boxwoods are boxwood leaf miner, boxwood mite and psyllids.
Uses:
Shrub borders. Incorporate into a foundation planting. Fastigiate habit gives this cultivar good specimen/accent value.
