Long Island's dense residential development makes privacy landscaping one of the most requested services we provide. The right hedge or shrub screen can transform a yard that feels overlooked from three directions into a genuine private outdoor retreat — but plant selection, spacing, and patience are all critical to success.
Best Privacy Hedge Plants for Long Island
Arborvitae (Thuja occidentalis and Thuja plicata varieties) is Long Island's most popular privacy hedge plant for good reason: it's evergreen, grows 2–3 feet per year when established, tolerates a wide range of soil conditions, and creates a dense visual barrier with reasonable trimming. 'Emerald Green' arborvitae is the most compact and formal-looking variety; 'Green Giant' (Thuja plicata hybrid) grows much faster (3–5 feet/year) and reaches 50–60 feet, making it better for larger properties needing rapid screening.
Privet (Ligustrum species) is the workhorse of Long Island hedging — extremely fast-growing, adaptable to sun and part shade, tolerant of salt spray, and responsive to heavy trimming. It is semi-deciduous in cold winters, dropping some leaves in January–February but re-leafing rapidly in spring. For true year-round screening, arborvitae is preferable.
Holly Hedges: The Underappreciated Option
American Holly (Ilex opaca) and its hybrid relatives make outstanding evergreen privacy hedges with a more naturalistic, softer appearance than arborvitae. They are native to Long Island, extremely hardy, salt-tolerant, and produce red berries that provide exceptional wildlife value. Sky Pencil Japanese Holly is excellent for narrow spaces — it grows 8–10 feet tall but only 2–3 feet wide, perfect for tight side yards.
Inkberry Holly (Ilex glabra) is the best choice for wet areas or rain garden edges where other privacy plants struggle. It tolerates standing water and handles coastal salt exposure better than virtually any other privacy screening plant on Long Island.
Spacing, Planting, and Timeline
Proper spacing at installation is critical: plant hedges too close together and you'll have dense lower growth that declines as plants compete for light; too far apart and you wait longer for screening. For arborvitae, 4–5 feet on center is standard for 'Emerald Green'; 6–8 feet for 'Green Giant'. For privet, 2–3 feet on center creates a dense hedge quickly.
Expect 3–5 years from planting to achieve functional privacy screening with most hedge species on Long Island. 'Green Giant' arborvitae can achieve 10–12 feet of screening in 3 years, making it the fastest-screening option for large properties.
