The 'Green Giant' Arborvitae is an exceptional privacy screen due to its incredibly fast growth rate (up to 3-5 feet per year once established). It adapts to a wide range of soils but performs best in moist, well-drained loams. Water deeply once or twice a week during its first two growing seasons. It naturally maintains a dense, pyramidal shape without pruning, but can be sheered in late winter or early spring if a formal hedge look is desired. It is highly resistant to deer and most diseases.
