How To
Wondering how tall can Emerald Green Arborvitae grow before it becomes a landscaping giant? This fast-growing evergreen 🌲 can reach between 12 to 15 feet at maturity, making it a popular choice for privacy screens and windbreaks—but its final height depends on where you plant it and how you care for it.
If you're planning to use it as a tall hedge or focal point, understanding its growth rate is key. In just 5 years, you'll see it climb to about 6 to 8 feet, and by 10 years, it’ll likely top out at its full height. That’s why knowing the right spacing and pruning techniques is so important.
This versatile shrub thrives in USDA Zone 6a and beyond, but its growth can be influenced by soil quality, sunlight, and even how often you trim it back. Whether you want a towering backdrop or a more manageable size, the right care makes all the difference.
Let’s break down exactly what affects its height—and how to keep it at your ideal size—so you can get the most out of this classic landscape staple.
Emerald Green Arborvitae mature height: exact growth rates by year and decade
The Emerald Green Arborvitae is a fast-growing evergreen that can reach 12 to 15 feet tall at maturity, but its growth rate varies by year and growing conditions. If you’re planning a privacy screen or windbreak, tracking its height progression helps you anticipate when it will fully fill its space. Here’s what to expect from planting to full maturity.
In its first year, you’ll see 2 to 3 feet of growth, and by year two, it can double that to 4 to 6 feet. This rapid early growth is one reason it’s so popular for quick landscaping projects. By year three, it typically reaches 6 to 8 feet, making it a noticeable addition to any yard.
By year five, your Emerald Green Arborvitae will likely hit 8 to 10 feet, and by year ten, it’ll be close to its mature height of 12 to 15 feet. If you’re planting multiple shrubs for a hedge, spacing them 3 to 5 feet apart ensures they’ll fill in beautifully without overcrowding.
Here’s a detailed breakdown of its growth progression over time, including key factors that influence its height:
| Stage | Height Range (ft) | Annual Growth Rate | Key Factors |
|---|---|---|---|
| Year 1 | 2–3 ft | 2–3 ft/year | Soil quality, sunlight |
| Year 2–3 | 4–8 ft | 3–4 ft/year | Watering, pruning |
| Year 4–5 | 8–10 ft | 2–3 ft/year | Climate, sunlight |
| Year 6–10 | 10–14 ft | 1–2 ft/year | Pruning, soil nutrients |
| Mature (10+ years) | 12–15 ft | Minimal growth | Maintenance, spacing |
The first 5 years are when your Emerald Green Arborvitae grows the fastest, adding up to 4 feet per year if conditions are ideal. After that, its growth slows as it matures, typically adding only 1 to 2 feet per year until it reaches its full height.
To maximize growth, plant it in well-draining soil with full sun exposure (6+ hours daily). If you’re in a cooler climate, like USDA Zone 6a, it may grow slightly slower, while warmer zones can accelerate its height. Regular watering and fertilizing in early spring also boost growth.
If you’re aiming for a taller privacy screen, avoid heavy pruning in the early years—let it grow naturally. However, if you want to control its height, pruning in late winter or early spring can help keep it more compact. Just be sure to prune no more than 25% of the foliage at a time to avoid stressing the plant.
Once established, this drought-tolerant shrub can handle drier conditions, but consistent moisture in the first few years ensures robust growth. Mulching around the base also helps retain moisture and regulate soil temperature, which supports steady height progression.
For a quick visual reference, imagine your Emerald Green Arborvitae reaching the height of a standard basketball hoop (10 feet) by year five, and fully maturing to 12 to 15 feet by year ten. With the right care, it’ll become a stunning, long-lasting feature in your landscape.

Emerald Green Arborvitae mature height: exact growth rates by year and decade
The Emerald Green Arborvitae is a fast grower, but its final height depends on growing conditions and care. On average, it reaches 12 to 15 feet at maturity, but with ideal conditions, it can grow even taller. Understanding its growth rate helps you plan for privacy screens, windbreaks, or landscape focal points.
In the first year, expect 2 to 3 feet of growth, with each subsequent year adding another 1 to 2 feet. By year 5, it typically stands 6 to 8 feet tall, making it a quick solution for many landscaping needs. Without proper care, it can easily exceed its expected height.
Here’s a detailed breakdown of its growth progression over time, including key factors that influence its height:
| Stage | Height Range | Annual Growth Rate | Key Factors |
|---|---|---|---|
| Year 1 | 2–3 ft | 2–3 ft | Soil quality, sunlight, watering |
| Year 2–3 | 4–6 ft | 1–2 ft/year | Pruning, nutrient availability |
| Year 4–5 | 6–8 ft | 1–1.5 ft/year | Sunlight exposure, soil drainage |
| Year 10+ | 12–15 ft | 0.5–1 ft/year | Climate, maintenance, pruning |
After 10 years, growth slows significantly, but without pruning, it can continue climbing. The USDA Zone 6a climate is ideal, but cooler zones may slow growth. For faster results, ensure it gets 6+ hours of sunlight and well-draining soil.
To maximize growth, plant in spring (April–May) and water deeply once a week. Avoid overwatering, as soggy soil can stunt growth. If you’re using it for a privacy screen, space plants 3–5 feet apart to allow for full growth without overcrowding.
With the right conditions, your Emerald Green Arborvitae can become a stunning, tall evergreen that enhances your landscape for decades. Just remember: consistent care keeps it at your desired height! 🌲
