Hedge Spacing Calculator — Emerald Green vs Green Giant Arborvitae and What Determines Privacy Screen Speed

The two most popular privacy hedges in the US — Emerald Green Arborvitae and Green Giant Arborvitae — are planted very differently, but homeowners constantly confuse their spacing requirements. Emerald Green (Thuja occidentalis ‘Smaragd’) stays narrow at 3–4 feet wide at maturity and grows slowly at about 4–6 inches per year. You plant it 3–3.5 feet on-center, and it takes 4–6 years to create a tight privacy screen. Green Giant (Thuja plicata ‘Green Giant’) is a completely different plant — it grows 3–5 feet per year, reaches 40–50 feet tall, and spreads 12–15 feet wide. Plant it 5–8 feet apart, and it creates a dense screen in 2–3 seasons. The trade-off: Green Giant needs a lot more room and looks like a solid wall of green year 10 vs. year 3.

The double staggered row is the solution most people miss. Instead of one line of plants, you plant two rows — with the back row offset by half the plant spacing, so each back-row plant fills the gap between two front-row plants. Two rows of Emerald Green at 3.5-foot spacing, with the back row staggered, creates canopy closure faster than a single row at 2.5-foot spacing — and looks more natural. The trade-off is that you need twice the plants and a planting bed at least 6–8 feet wide.

Quick spacing reference for the most common US privacy hedges: Emerald Green Arborvitae: 3–3.5 ft on-center, 3–4 ft wide, 12–15 ft tall, ~4–6 in/yr. Green Giant Arborvitae: 5–8 ft, 12–15 ft wide, 30–50 ft tall, 3–5 ft/yr. Leyland Cypress: 6–8 ft, 15–20 ft wide, 40–60 ft tall, 3–4 ft/yr. Nellie Stevens Holly: 4–6 ft, 8–12 ft wide, 15–25 ft tall, 2–3 ft/yr. Skip Laurel: 3–5 ft, 8–12 ft wide, 10–18 ft tall, 1–2 ft/yr (deer-resistant, shade-tolerant alternative to arborvitae).

Example 1: Nashville, TN — Emerald Green Arborvitae, 100 ft Backyard Privacy Screen

Nashville, Tennessee — new backyard privacy hedge along rear property line, 100 linear ft

A Nashville homeowner needs a 100-foot privacy screen along the rear property line, replacing a wood fence that rotted out. She chooses Emerald Green Arborvitae at 3.5-foot spacing — narrow enough to fit along the property line without encroaching on the neighbor’s side.

StepCalculation

Growth rate~0.5 ft/yr (Emerald Green is slow)
Privacy (6 ft height)(6 – 3) ÷ 0.5 = 6 years — canopies touch at 4-5 years
Cost at $45/plant33 × $45 = $1,485
✅ Nashville tip: UT Extension recommends Emerald Green Arborvitae as the best privacy hedge for Tennessee homeowners in USDA Zones 6–7a covering most of Middle Tennessee. At 3.5-foot spacing, canopies will begin touching around year 4–5, with full privacy at 6–7 years. If faster privacy is needed, reduce spacing to 3 feet (34 plants) or plant in a double staggered row (60 plants) — the double row achieves canopy closure in 2–3 years from the gaps filling in.

Example 2: Seattle, WA — Skip Laurel Double Staggered Row, 60 ft, Shaded Side Yard

Seattle, Washington — shaded side yard between houses, 60 ft, needs year-round screening

A Seattle homeowner has a 60-foot shaded side yard between his house and the neighbor’s, getting only 2–3 hours of afternoon sun daily. Arborvitae won’t work in this shade. Skip Laurel is the recommended evergreen hedge for Pacific Northwest shade. He wants a double staggered row for faster screening — two rows offset for maximum gap coverage.

✅ Seattle tip: OSU Extension identifies Skip Laurel as the top recommendation for Pacific Northwest evergreen hedges in full to part shade — environments where arborvitae, Leyland cypress, and most other privacy hedge choices fail. At 4-foot spacing in a double row, Skip Laurel creates privacy screening faster than single-row arborvitae at the same spacing, and the wider spreading habit means canopies overlap substantially within 2-3 years. Be aware that Skip Laurel spreads wider than arborvitae (8-12 ft) and needs a planting bed at least 6-8 ft wide for a double row.

Example 3: Charlotte, NC — Nellie Stevens Holly, 120 ft, Deer-Resistant Screen

Charlotte, North Carolina — rural property with deer pressure, 120 ft rear boundary, fast privacy needed

A Charlotte-area homeowner on a wooded lot has heavy deer pressure — arborvitae has been badly damaged by deer browsing. He switches to Nellie Stevens Holly, which deer avoid due to its spiny leaves, at 5-foot spacing for a 120-foot boundary screen.

StepCalculation

✅ Charlotte tip: NC State Extension recommends Nellie Stevens Holly as one of the top deer-resistant evergreen hedges for the Piedmont and Foothills of North Carolina. At 5-foot spacing, the mature plants (15-25 ft tall, 8-12 ft wide) will create a substantial year-round screen with attractive red berries throughout winter. Plant at 5 ft rather than 6 ft for faster screen closure — at 2-3 ft/yr growth, canopies begin touching at 5-foot spacing within 2-3 years.

Three Expert Tips for Successfully Establishing a Privacy Hedge

1

Water New Hedges Weekly for the Entire First Season — Not Just at Planting

The leading cause of hedge failure in the US is inadequate watering during the first 12 months after planting. The mistake homeowners make is watering thoroughly at planting day and then assuming the plants are established. Arborvitae, holly, laurel, and most other evergreen hedge plants need consistent weekly watering through the first full growing season — even when it’s not particularly hot. During the critical first-year establishment period, the root system is still largely confined to the original root ball and has not yet spread into the surrounding soil. A thorough once-per-week deep watering (equivalent to 1-1.5 inches of water) is far more effective than light daily watering — deep watering encourages roots to grow downward and outward, while light frequent watering keeps roots near the surface where they’re vulnerable to drought and temperature stress.

2

Don’t Plant Closer Than Recommended Just to Get Privacy Faster — You’ll Regret It

The most common hedging mistake: a homeowner wants faster privacy, so they plant Emerald Green Arborvitae at 2 feet instead of 3.5 feet. For the first 3–5 years, this looks great — dense and fast. By year 8–10, the individual plants are competing intensely for light and water. The inner branches of tightly-planted arborvitae brown out and die as they can’t get light. The outer canopy looks fine, but if you ever trim back to the browning interior, it won’t regrow. Plants that are too close together eventually begin pushing each other sideways, roots compete for nutrients, and the hedge thins from the inside out. If you absolutely want faster privacy at normal spacing, plant annual tall grasses or fast-growing annual privacy screens (like giant marigolds or sunflowers) between the permanent hedge plants for the first 2–3 seasons, then remove them as the permanent hedge fills in.

3

Check Invasive Species Lists Before Planting Privet, Burning Bush, or Leyland Cypress

Three of the most commonly recommended fast-privacy hedges in the US have significant invasive species issues in certain regions that homeowners are not warned about. Japanese privet (Ligustrum japonicum) and common privet (Ligustrum vulgare) are listed as invasive in 30+ US states, particularly across the Southeast, mid-Atlantic, and Pacific Northwest where they spread aggressively from berries dropped by birds. Burning bush (Euonymus alatus) is listed as invasive or restricted in Connecticut, Massachusetts, New Hampshire, and several other northeastern states. Leyland Cypress, while not invasive, is prone to several fatal diseases (seiridium canker, cercospora blight) in humid Southeast climates that can kill established plants within a few years. Check your state’s invasive species list at invasivespeciesinfo.gov before purchasing any of these species.

Frequently Asked Questions About Hedge Spacing

How far apart should I plant arborvitae for a privacy screen?+
Spacing depends on the arborvitae variety: Emerald Green Arborvitae (Thuja occidentalis ‘Smaragd’) — plant 3–3.5 ft on-center. It grows 3–4 ft wide at maturity, so plants at 3-3.5 ft will grow together nicely. Green Giant Arborvitae (Thuja plicata ‘Green Giant’) — plant 5–8 ft on-center. It grows 12–15 ft wide at maturity. At 5-foot spacing, canopy closure happens in 2-3 seasons. At 8-foot spacing, canopies touch at 5-7 years. Techny Arborvitae — plant 4–5 ft on-center for a hedge screen. Never plant Emerald Green at less than 3 feet — they will eventually crowd each other and brown from the inside out.
What is the fastest growing privacy hedge?+
The fastest-growing common US privacy hedges are: Green Giant Arborvitae (3–5 ft/yr), Leyland Cypress (3–4 ft/yr), Privet (2–3 ft/yr), and Nellie Stevens Holly (2–3 ft/yr). Green Giant is generally the fastest and most widely available across the US, but it gets very large (30–50 ft tall, 12–15 ft wide) — not suitable for tight spaces or near utilities. Leyland Cypress is equally fast but more disease-prone in humid southeastern climates. For tight spaces, privet (2.5 ft wide) is the fastest choice that stays manageable, though it’s invasive in many states.
What is a double staggered row hedge?+
A double staggered row means planting two parallel rows, with the second row offset by half the spacing distance, so each plant in row 2 fills the gap between two plants in row 1. This creates privacy faster because the staggered plants fill the gaps between rows from both sides simultaneously. For a hedge screen, a double staggered row achieves canopy closure 1–2 growing seasons faster than a single row at the same spacing. The trade-off: you need twice as many plants and a planting bed 6–8 feet wide. Use this calculator’s double row option to see the exact plant count comparison.
How long does it take for a hedge to fill in?+
It depends on species, starting size, and spacing: Emerald Green Arborvitae at 3.5 ft spacing, planted at 3 ft tall: 4–6 years to full privacy. Green Giant Arborvitae at 5 ft spacing, planted at 4 ft tall: 2–3 years to 8 ft privacy. Leyland Cypress at 6 ft spacing, planted at 5 ft: 2–3 years. Skip Laurel at 4 ft, planted at 3 ft: 4–5 years. Nellie Stevens Holly at 5 ft, planted at 5 ft: 2–3 years. The privacy timeline in this calculator shows estimated height at each year based on the species growth rate — use it to set realistic expectations before purchasing.
What is the best privacy hedge for deer?+
The most deer-resistant US privacy hedges: Nellie Stevens Holly — spiny leaves deer avoid; fast growing 2-3 ft/yr; red berries in winter. Skip Laurel — moderately deer resistant; tolerates shade; good for Pacific NW and mid-Atlantic. American Holly — very deer resistant; native species; slow growing. Foster Holly — deer resistant; faster than American holly. Boxwood — generally deer resistant though deer will eat it when hungry. Avoid for deer-pressure areas: arborvitae (heavily browsed), privet, leyland cypress. If deer pressure is severe, a temporary physical fence 6-8 ft tall around new plants for the first 1-2 years is the most effective protection while plants establish.
How many Leyland Cypress do I need for a 100-foot hedge?+
At 6-foot spacing: 100 ÷ 6 + 1 = 17.7 + 1 = 18 plants (single row) plus 10% contingency = 20 plants. At 8-foot spacing: 100 ÷ 8 + 1 = 12.5 + 1 = 14 plants, buy 16. Leyland Cypress grows 3–4 ft per year, so at 6-foot spacing, canopies begin touching in 2–3 seasons. Warning: in the southeastern US (North Carolina, Virginia, Georgia), Seiridium canker fungal disease can kill established Leyland Cypress within 5–10 years. NC State Extension recommends Green Giant Arborvitae as a disease-resistant alternative in that region.
What is the difference between Emerald Green and Green Giant Arborvitae spacing?+
Emerald Green: 3–3.5 ft on-center. Grows 3–4 ft wide, 12–15 ft tall. 4–6 in/yr growth (very slow). Takes 4–6 years for privacy screen at 3.5-ft spacing. Ideal for tight spaces along fences and property lines. Green Giant: 5–8 ft on-center. Grows 12–15 ft wide, 30–50 ft tall. 3–5 ft/yr growth (very fast). Takes 2–3 years for privacy at 6-ft spacing. Needs a much wider planting area. Best for large properties where ultimate size is not a concern. The key mistake: people buy Green Giant thinking it will stay the size it was at the nursery. At 30–50 ft tall and 12–15 ft wide, mature Green Giants require enormous space and are not appropriate near houses or property lines.
Should I plant hedge plants in spring or fall?+
For most US regions, fall planting (September through November) is actually better than spring for most hedge plants. Fall planting allows 6–8 weeks of root establishment before winter dormancy — the roots keep growing even after the top of the plant stops. Spring planting immediately subjects new plants to heat and drought stress before roots are established. Specific timing: cool-season (zones 4–6): September 1 – October 31 for fall, or April 15 – May 31 for spring. Warm-season (zones 7–9): October 1 – December 31 (plants remain active through mild winters). The exception: if your winter temperatures regularly drop below 0°F, spring planting after the last frost date is safer to avoid winter-kill of freshly planted root systems.
How deep and wide should I dig for hedge plants?+
For container nursery stock: dig a hole 2 times as wide as the container and equal to the container depth (not deeper). Wide holes are far more important than deep holes — the roots spread outward, not downward. The top of the root ball should sit level with or slightly above the surrounding soil to avoid crown rot. Planting too deep is the most common installation error and kills more hedge plants than any other mistake. For balled-and-burlapped (B&B) stock: the same rule applies. Remove the burlap and wire cage from the top third of the root ball after placing it in the hole. Backfill with the native soil from the hole — do not amend with compost unless your soil is extremely poor, as amended pockets can cause roots to stay in the planting hole rather than spreading into the surrounding soil.
How much do hedge plants cost?+
Hedge plant costs by container size: 1-gallon: $5–15, typically 12–18 inches tall. 3-gallon: $25–45, typically 2–3 feet tall. 7-gallon: $50–90, typically 4–6 feet tall. 15-gallon: $100–200, typically 5–8 feet tall. B&B (balled and burlapped): $100–300+, typically 6–10 feet. For a 100-foot hedge in 3-gallon Emerald Green Arborvitae at 3.5-foot spacing: ~30 plants at ~$35 each = ~$1,050 materials. A 7-gallon gives immediate visual impact but costs 2–3× as much. The 3-gallon stock at 3.5-foot spacing will look as good as 7-gallon stock at 4-foot spacing by year 3.
