A single bare fence line or overlooking neighbor can turn a backyard sanctuary into a fishbowl. The difference between a sparse, patchy property line and a dense, living wall of emerald green comes down to choosing the right evergreen from the start. Arborvitae trees are the go-to solution for homeowners who want rapid privacy without the sterile look of a solid fence, but the sheer number of sizes, growth rates, and hardiness zones can paralyze even experienced landscapers.
I’m Mohammad Maruf — the founder and writer behind Gardening Beyond. I spend my time cross-referencing nursery data, USDA zone maps, and aggregated owner feedback spanning thousands of planted specimens to determine which green arborvitae trees actually deliver on their growth promises instead of arriving as twigs that never take off.
After comparing root system quality, shipping survival rates, and mature canopy measurements, I’ve distilled the market into a shortlist of reliable options. This guide delivers the objective data you need to pick the best green arborvitae tree for your specific property, climate, and budget constraints.
How To Choose The Best Green Arborvitae Tree
Arborvitae trees are not a one-size-fits-all evergreen. Selecting the wrong cultivar for your planting zone or spacing them too far apart leads to leggy gaps that never fill in. Focus on three non-negotiable factors before clicking “buy.”
USDA Hardiness Zone Compatibility
Each arborvitae variety has a specific zone range where it thrives. Emerald Green (Thuja occidentalis ‘Smaragd’) performs reliably in zones 2–7, while Green Giant (Thuja plicata x standishii) prefers zones 5–9. Planting a zone-7 tree in zone-3 soil guarantees winter kill. Check your local agricultural extension map and match it to the nursery’s listed zone rating before ordering.
Mature Dimensions and Spacing Strategy
The biggest landscaping mistake is ignoring the final height and spread. An Emerald Green that tops out at 14 feet tall and 4 feet wide needs different spacing (3–4 feet apart for a hedge) than a Green Giant that can hit 50 feet tall and 20 feet wide (6–7 feet apart). Measure your planting strip width and overhead clearance before you choose between columnar and pyramidal forms.
Container Size vs. Root System Development
A 1-gallon pot with a 6-inch top is cheaper than a 3-gallon specimen, but the root mass tells the real story. A well-rooted 3-gallon tree often establishes twice as fast in the first year because it has a larger soil ball and less transplant shock. Budget-tier multi-packs save money per unit but require extra care during the first growing season to ensure they don’t dry out before the roots spread.

In‑Depth Reviews
1. Perfect Plants Thuja Green Giant 2ft. Tall 8-Pack
This 8-pack is the closest you can get to an instant privacy wall without buying mature ball-and-burlap specimens. Each tree ships at roughly 24 inches tall with a developed root system in its own container, giving you a full year of growth advantage over 6-inch plugs. Reviewers consistently praise the packaging — thick boxes, plastic wrap around the base paper — that keeps the foliage intact even on cross-country shipments.
The Green Giant genetics mean you are looking at a potential mature height of 50–60 feet with a 20-foot spread, so plan spacing carefully (6–7 feet apart for a continuous hedge). Owners report that these trees put on 2–3 feet of height per season after the first year of establishment. The pyramid shape is wide at the bottom, which blocks ground-level sight lines effectively if you space them correctly.
A handful of buyers noted that not every stem measured a full 24 inches — some came in closer to 18 inches — but the root quality was uniformly strong. The dense, dark green foliage releases a pine-like fragrance when brushed, and the trees thrive across zones 5–9 with minimal maintenance once the roots anchor. This is the top-tier pick for anyone who wants to skip the two-year wait for a bare-root hedge.
What works
- Pre-grown 24-inch stems cut establishment time by a full season
- Exceptional packaging prevents shipping damage even in cold weather
- Strong branching structure from day one compared to cheaper starter pots
What doesn’t
- Some trees arrive slightly under the advertised 2-foot height
- Premium price per plant compared to bare-root multi-packs
2. Green Promise Farms ‘Smargd’ Emerald Green Arborvitae (3-Gallon)
The ‘Smargd’ cultivar is the gold standard for narrow columnar hedges, and this 3-gallon container from Green Promise Farms delivers a specimen that is ready to plant immediately. At 18–20 feet tall with a mature spread of only 5–6 feet, this tree fits into tight side-yard corridors where Green Giants would be too wide. The rich emerald foliage holds its color through winter without the bronze tint that some arborvitae varieties develop in cold months.
Buyers who ordered multiple units reported that all arrived with bright green foliage and moist root balls despite the boxes taking some beating during transit. The root system in the #3 container is significantly more developed than what you get from 1-gallon pots, which translates to faster vertical growth in the first year. The tree thrives in zones 3–8, making it one of the most cold-hardy columnar evergreens on the market.
A small number of customers noted that the trees were shorter than expected for the price point, but the consensus is that the quality of the root structure and the absence of transplant shock make it worth the investment. If you need a formal hedge that stays tight and upright without constant pruning, this is the cultivar to buy. The deer resistance rating is moderate — young trees still benefit from fencing in high-pressure areas.
What works
- Columnar form at 5–6 ft wide fits narrow property lines perfectly
- 3-gallon root ball eliminates transplant shock versus smaller pots
- Winter color retention stays emerald green without bronze discoloration
What doesn’t
- Price per plant is higher than multi-pack starter options
- Slow initial growth compared to Green Giant variety
3. Green Promise Farms Thuja Green Giant (3-Gallon)
If your goal is a tall windbreak or a massive privacy screen that blocks two-story windows, the Thuja Green Giant is the undisputed workhorse. This 3-gallon pot from Green Promise Farms delivers a fully rooted plant that can eventually reach 30–50 feet in height with a spread of 12–16 feet. The growth rate is the fastest in the arborvitae family — up to 3–4 feet per year once established, which means a 2-foot starter can hit 8 feet within three seasons.
The medium green foliage is dense and soft to the touch, creating a solid visual barrier even in winter when deciduous trees drop their leaves. Owners consistently report that the plants arrive in good condition, with the root ball intact and the stems flexible from careful packing. The tree is hardy in zones 4–8 and tolerates both full sun and partial shade, though full sun produces the thickest growth.
The main trade-off is space — this tree needs room to spread. Planting it closer than 6 feet apart forces it to compete for sunlight and can lead to lower branch die-off. Several buyers mentioned that the 13-pound shipping weight signals a substantial soil mass, which is exactly what you want for a tree that will double in size annually. For sheer cubic footage of greenery per dollar, this is the most efficient choice.
What works
- Fastest growth rate in the arborvitae family at 3–4 ft/year
- Massive 3-gallon root ball supports rapid establishment
- Tolerates full sun and partial shade with consistent moisture
What doesn’t
- Needs 12–16 ft of horizontal space at maturity
- Not suitable for small urban lots or narrow side yards
4. Perfect Plants Thuja Green Giant 1 Gallon 5-Pack
This 5-pack from Perfect Plants bridges the gap between cost-conscious bulk buying and the head start of container-grown trees. Each plant ships in its own 1-gallon pot with a well-developed root system, which gives it a significant advantage over bare-root or plug-size alternatives. The Green Giant genetics give you the same 3-foot-per-year growth potential as the larger 8-pack, but at a lower upfront investment per plant.
The packaging is identical to the premium 8-pack — individual plastic wrapping, base paper, and a reinforced box that keeps the soil intact during shipping. Buyers noted that the root balls were moist and the top growth was lush, with several reviewers specifically calling out the absence of broken branches despite cross-country delivery. The trees are rated for zones 5–9 and perform best in full sun with regular watering during the first dry season.
The realistic downside is that 1-gallon pots produce smaller root masses than 3-gallon containers, so the trees may take an extra season to catch up in height. Consistent watering in the first summer is critical — missing a week of irrigation can set them back significantly. If you are planting a long hedge and want the best value per tree while still getting a container-grown start, this 5-pack hits the sweet spot.
What works
- Container-grown roots outperform bare-root alternatives for survival rate
- 5-pack offers the lowest per-plant cost in the container-grown tier
- Same fast-growing Green Giant genetics as the premium 8-pack
What doesn’t
- Smaller 1-gallon root ball needs extra watering vigilance in year one
- Stems are shorter than the 8-pack version at delivery
5. 10 Thuja Green Giant Arborvitae 7-10 inches Tall Trees
For the gardener with patience and a large property line to fill, this 10-pack of 7–10 inch starter trees offers the highest volume of plants per dollar. The Green Giant genetics mean each tiny start has the potential to grow 3 feet per year, eventually hitting 40 feet in height and 15 feet in spread. The key is understanding that these are bare-root or small pot starts — they need careful babying through the first season to reach their potential.
Users who succeeded with these trees emphasized a strict watering regimen — 2–3 times per week with a drip bucket or soaker hose — and protection from deer browsing while the plants are small. Several reviewers reported that the trees survived harsh Missouri winters and doubled in size within 12 months when given consistent moisture and occasional fertilizer. The trees ship in their growing medium and should be planted after the last frost date in spring.
The biggest risk is drought stress: the small root system cannot draw water from deep soil, so a week of neglect can turn the foliage orange. The 5-day guarantee from the nursery only covers arrival condition, not long-term survival, so your aftercare discipline determines whether this is a bargain or a loss. For the gardener who is willing to irrigate on a schedule, this pack delivers the most linear feet of future hedge per dollar spent.
What works
- 10 plants give the highest coverage per dollar for long hedge runs
- Fast genetic growth rate of 3 ft/year once roots establish
- Deer-resistant at maturity despite vulnerability when very small
What doesn’t
- Tiny 7–10 inch starts require intensive first-year watering
- No container soil cushion — dries out faster than potted trees
6. Perfect Plants Emerald Green Arborvitae (1 Gallon)
The Emerald Green arborvitae is the go-to choice for northern gardeners who need a tree that stays pristine through zone-2 winters without browning. This 1-gallon pot from Perfect Plants ships a compact, low-maintenance evergreen that matures at 14 feet tall and only 4 feet wide, making it ideal for foundation planting or tight hedge rows where Green Giants would overwhelm the space. The columnar form means you can plant them 3 feet apart for a solid screen without crowding.
Reviewers consistently noted that the tree arrived exceeding the expected height — many reported plants closer to 2 feet tall than the advertised 1.5 feet — with the soil still moist and no signs of transplant shock. The deer resistance rating is higher than many other arborvitae varieties, though young plants still benefit from a cage for the first winter. The drought tolerance is moderate; regular watering through the first two summers is recommended to build a deep root system.
The compact size is a double-edged sword: if you need a 50-foot screen, this cultivar will take decades to reach that height. It is a slow to moderate grower compared to the Green Giant, adding roughly 1–2 feet per year. Buyers who want a low-maintenance, cold-hardy evergreen for a front-yard accent or a formal hedge that requires little pruning will find this an excellent match. The 1-gallon pot size gives you a head start over bare-root without the premium price of a 3-gallon container.
What works
- Exceptional cold hardiness down to zone 2 with no winter burn
- Compact 4-foot width fits foundation plantings and small hedges
- Higher deer resistance than Green Giant for low-pressure areas
What doesn’t
- Slow growth at 1–2 ft/year compared to Green Giant varieties
- Only reaches 14 ft tall — unsuitable for blocking two-story structures
7. 5 Thuja Green Giant Arborvitae (6–12 inches) 5-Pack
This entry-level 5-pack is designed for the gardener who wants to test Green Giant genetics without a significant financial commitment. Each plant ships in a 2.5-inch pot at 6–12 inches tall, which is the smallest size in this roundup. The trade-off is clear: you save money upfront, but you need to provide attentive care through the first season to get the plants established. The natural pyramid shape and low-maintenance reputation still apply once the roots anchor.
Buyers who left positive reviews emphasized that the trees arrived healthy and well-packaged for their size, with several customers ordering additional packs after seeing the initial quality. The dark green foliage may turn a light bronze color during winter, which is a normal cold-weather response for this cultivar and not a sign of distress. The trees thrive in zones 5–8 and tolerate both full sun and partial shade, though full sun produces denser branching.
The failure rate is higher with this size than with larger container plants — a small percentage of buyers reported that their trees did not survive shipping or the first month in the ground. The 2.5-inch pot means the root system is still developing, so transplant shock is a real risk. For the budget-conscious homeowner who has time to baby these starts through the first growing season, this pack offers a low-cost entry to a full privacy hedge, but the patience required is substantial.
What works
- Lowest upfront cost per plant in the lineup
- Natural pyramid shape requires no pruning as it matures
- Packs well for shipping with minimal soil spillage
What doesn’t
- Small 2.5-inch root system is vulnerable to transplant shock
- Higher failure rate reported compared to gallon-size containers
- Needs consistent watering vigilance through the first summer
Hardware & Specs Guide
Mature Height & Spread
The final size of an arborvitae determines spacing and long-term suitability. Emerald Green cultivars top out at 14–20 feet tall with a 4–6 foot spread, making them ideal for foundation hedges and narrow corridors. Green Giant varieties can reach 40–60 feet tall with a 15–20 foot spread — they need open space and 6–7 foot spacing to develop properly without crowding.
Annual Growth Rate
Green Giant arborvitae are the fastest-growing evergreen privacy trees, adding 3–4 feet per year after the first season of establishment. Emerald Green grows at a moderate 1–2 feet annually, which means a 2-foot starter takes 6–8 years to reach 14 feet. Matching growth rate to your patience level and privacy timeline is critical — Green Giants fill in faster but require more substantial spacing.
