Arborvitae vs. Leyland Cypress vs. Green Giant: Which Privacy Tree Is Best for NC?
The definitive guide for North Carolina homeowners who want fast, year-round privacy—without the guesswork.
If you’re a North Carolina homeowner searching for the best fast-growing privacy trees for your yard, you’ve almost certainly come across three names: Arborvitae, Leyland Cypress, and Green Giant Arborvitae. All three are evergreen, all three grow tall, and all three look great—but they are not the same. Plant the wrong one in the Piedmont clay and you’ll know it within a year.
At Piedmont Privacy Trees, we’ve installed hundreds of privacy tree rows across Lexington, High Point, Thomasville, Clemmons, and the surrounding Piedmont Triad. This guide breaks down exactly how each tree performs in North Carolina’s specific climate and soil so you can make the best decision for your property.

1. Arborvitae (Thuja occidentalis) — The Classic Choice
When most people picture a privacy hedge, they’re picturing an Arborvitae. The ‘Emerald Green’ Arborvitae is the most common variety planted in North Carolina neighborhoods, and for good reason: it’s compact, neat, and evergreen year-round. At maturity it typically reaches 12–15 feet tall and only 3–4 feet wide, making it ideal for tight fence lines or small suburban lots.
Where Arborvitae Thrives in NC
Arborvitae performs best in USDA zones 3–7, which covers most of western and central North Carolina. However, in the hot, humid summers of the Piedmont Triad—Lexington, High Point, and the surrounding areas—this tree can struggle. It prefers well-drained, slightly acidic soil and doesn’t love the heavy clay common across Davidson County.
Arborvitae is highly susceptible to deer browsing in rural NC areas, and it can suffer in the heavy clay soils typical across the Piedmont without proper soil amendment. It also has a slower growth rate than the other two options on this list, averaging only 1–2 feet per year.
Pros & Cons for NC Homeowners
- Compact size, great for small lots
- Naturally pyramidal shape—no pruning required
- Dense, year-round green coverage
- Widely available and affordable
- Low maintenance once established
Bottom line: If you have a small yard, want a tidy, low-maintenance hedge under 15 feet, and aren’t in a deer-heavy area, Arborvitae is a solid pick. But if you need fast, tall, full privacy on a typical NC suburban or rural lot, keep reading.
2. Leyland Cypress — The Fast Grower with a Catch
The Leyland Cypress exploded in popularity across North Carolina in the 1990s and 2000s—and for obvious reasons. It grows an astonishing 3–5 feet per year, reaches 40–70 feet at maturity, and creates a thick, feathery green wall remarkably fast. For a few years after planting, it looks incredible.
The problem? North Carolina’s warm, humid summers combined with the tree’s rapid growth create perfect conditions for Seiridium canker and Botryosphaeria canker—fungal diseases that can devastate Leyland Cypress plantings, especially when trees are planted too close together and airflow is restricted.
Many NC homeowners who planted Leyland Cypress rows in the 2000s have had to remove entire rows due to canker disease. We regularly provide tree removal services in Lexington NC for failed Leyland Cypress plantings. If you have dying or diseased Leylands on your property, our team can help.
When Leyland Cypress Still Makes Sense
Leyland Cypress isn’t all bad. On large rural lots with good airflow, proper spacing (8–10 feet apart minimum), and well-drained soil, it can perform beautifully for decades. It’s also a strong windbreak option for exposed properties and handles coastal North Carolina conditions reasonably well. The key is proper spacing and professional installation—crowded Leyland Cypress is a recipe for disease.
3. Green Giant Arborvitae — The Best Privacy Tree for NC
If there’s one tree we recommend above all others for privacy tree installation in North Carolina, it’s the Green Giant Arborvitae (Thuja standishii × plicata). It combines the fast growth of the Leyland Cypress with the reliability and disease resistance that North Carolina’s climate demands.
The Green Giant grows 3–5 feet per year, reaches 40–60 feet at maturity, and maintains a rich, emerald-green color year-round. But what really sets it apart is its toughness. Unlike its relatives, the Green Giant is:
Green Giant Arborvitae is remarkably resistant to Seiridium canker, highly tolerant of Piedmont clay soil, handles NC summer heat and humidity without stress, and shows significantly better deer resistance than standard Arborvitae. It’s the closest thing to a perfect privacy tree for the Lexington, High Point, and Thomasville area.
Green Giant Performance in Piedmont NC Soil
One of the most common questions we get is: “Will this tree handle Davidson County clay?” The answer with Green Giant is a confident yes—provided the planting hole is prepared correctly. Green Giant has a more adaptable root system than either Arborvitae or Leyland Cypress, and with proper soil amending and drainage preparation, it establishes quickly and grows vigorously even in the heavy red clay soil of the Piedmont Triad.
Our professional privacy tree installation service includes full site assessment, soil preparation, and proper spacing layout—all of which are critical to getting the most out of your Green Giant investment.
NC-Specific Factors That Change Everything
What works in Virginia or Georgia doesn’t automatically work in the Piedmont Triad. Here’s what every NC homeowner needs to know before planting a privacy tree row:
Piedmont Clay Soil
Davidson, Forsyth, Guilford, and Randolph counties are dominated by heavy red clay soil that drains poorly and compacts easily. This is the single biggest killer of Arborvitae in our region. Green Giant’s more aggressive root system adapts better, but even Green Giants benefit from proper planting hole preparation, organic matter addition, and initial mulching. Our team performs thorough soil prep before every installation.
Heat & Humidity
NC summers are long, hot, and humid—conditions that stress Arborvitae and create disease pressure for Leyland Cypress. Green Giant was specifically selected for superior performance in exactly these conditions, making it the clear winner for our region’s climate.
Deer Pressure
If you live near wooded areas in Davidson County or the rural outskirts of High Point and Thomasville, deer are a real threat. Standard Arborvitae are a favorite deer food and can be devastated over a single winter. Green Giant is significantly less palatable to deer and is the safer long-term choice in deer-prone areas.
Spacing for Maximum Privacy
Improper spacing is one of the most common mistakes we see. Planting too close creates disease-prone crowding; planting too far apart leaves gaps for years. Our recommended spacing for Green Giant in NC suburban settings is 5–6 feet on center for a tight privacy screen, or 8 feet on center for a more open, naturalistic look that fills in over time.

Frequently Asked Questions
In North Carolina’s climate, Green Giants typically grow 3–5 feet per year when planted correctly with adequate soil preparation and watering during the first two seasons. In ideal conditions on well-prepared Piedmont soil, they can exceed 5 feet in a single growing season.
Not necessarily a bad choice, but a risky one without proper planning. The combination of NC humidity and dense planting creates severe disease pressure. If you go with Leyland Cypress, hire a professional to ensure correct spacing, good drainage, and ongoing monitoring for canker disease.
For a dense privacy screen with Green Giant, plan for one tree every 5–6 feet. For a 100-foot fence line, that’s approximately 17–20 trees. Our team will walk your property and give you a precise count based on your specific layout and goals.
Yes—with the right preparation. Piedmont clay requires proper hole sizing, organic matter amendment, and careful attention to drainage before planting. Green Giant Arborvitae is the most clay-tolerant of the three trees in this comparison, but professional site preparation still makes a significant difference in long-term health and growth rate.
Absolutely. We serve the entire Piedmont Triad including High Point, Thomasville, Lewisville, Clemmons, and the surrounding communities. Call us at (336) 596-7916 for a free property assessment.
The two best windows are early spring (March–April) and fall (September–November). Fall planting is often ideal in NC because cooler temperatures reduce transplant stress while the soil is still warm enough to encourage root establishment before winter. Our team plants year-round and can advise on the best timing for your specific situation.
The Verdict: Green Giant Arborvitae Is the Best Privacy Tree for NC
After hundreds of privacy tree installations across Davidson County and the Piedmont Triad, our recommendation is consistent: Green Giant Arborvitae is the best all-around privacy tree for most North Carolina homeowners.
