How To
If you're planning your landscape and wondering "how tall do arborvitae emerald green grow", you're about to discover why this evergreen is a garden favorite—and how to make the most of its space. The Emerald Green Arborvitae 🌲 isn’t just a pretty face; it grows into a sturdy, 12-15 feet tall shrub that adds year-round structure to any yard.
What makes this plant so popular? For starters, it grows at a steady pace—adding 2-3 feet per year in ideal conditions. By year three, you’ll already see it reaching 6-8 feet, so patience pays off as it matures into a privacy screen or focal point. The key to maximizing its height? Planting it in well-draining soil with partial sun and giving it enough breathing room.
But here’s the thing: without proper spacing or pruning, its growth can get out of hand. Too close to other plants or structures, and you’ll end up with a cramped, overgrown mess. The good news? With the right techniques, you can shape it to fit your space perfectly—whether you want a tall hedge or a neatly trimmed accent plant.
Ready to plan your landscape like a pro? I’ll walk you through everything you need to know—from spacing guidelines to pruning tips—to keep your Emerald Green Arborvitae thriving at the perfect height for your yard. Let’s get started!
Arborvitae Emerald Green mature height: year-by-year growth chart and spacing requirements
If you're planning to add Arborvitae Emerald Green to your landscape, understanding its growth patterns is essential. This popular evergreen typically reaches 12–15 feet tall at maturity, but its height progression varies significantly by year. Knowing these growth stages helps you space plants correctly and avoid overcrowding.
The Emerald Green Arborvitae is a fast-growing shrub, but its growth rate slows as it matures. In ideal conditions, you can expect 1–2 feet of growth per year during its first decade. Proper spacing ensures each plant has room to thrive without competing for nutrients or sunlight.
For single specimens, allow 3–4 feet of space around the base. When planting hedges or multiple rows, space them 3–5 feet apart to maintain airflow and prevent disease. This spacing also makes future pruning and maintenance easier.
At maturity, Arborvitae Emerald Green stands taller than a basketball hoop (about 10 feet), making it ideal for privacy screens or focal points. Its narrow, columnar shape (3–4 feet wide) ensures it won’t overwhelm smaller yards. For urban landscapes, consider its height when planting near power lines or sidewalks.
To encourage optimal vertical growth, plant in well-draining soil with partial sun exposure. Avoid heavy clay soils, which can stunt root development. Mulching around the base helps retain moisture and regulates soil temperature, supporting consistent height progression.
If you’re planting multiple Emerald Green Arborvitae for a hedge, aim for 5–6 feet between rows to allow airflow and reduce disease risk. Overcrowding can lead to stunted growth or fungal issues like canker disease. Regular pruning in late winter or early spring helps maintain a clean, uniform appearance.
For container growing, choose large pots (at least 24 inches deep) to accommodate root growth. However, expect slightly slower height progression due to limited root space. In-ground planting is ideal for maximizing the 12–15-foot mature height potential.
Remember, pruning too aggressively can reduce growth vigor. Focus on shaping rather than height reduction unless you’re managing a hedge. With proper care, your Arborvitae Emerald Green will reach its full height potential while adding year-round greenery to your landscape.
Arborvitae Emerald Green mature height: year-by-year growth chart and spacing requirements
The Arborvitae Emerald Green is a popular choice for privacy screens and hedges, thanks to its fast growth rate and striking evergreen foliage. At maturity, this variety typically reaches 12 to 15 feet tall with a spread of 3 to 4 feet, making it ideal for medium to large landscapes. Understanding its growth progression helps you plan spacing and maintenance effectively.
In the first year, you’ll see 2 to 3 feet of growth, which accelerates in subsequent years. By year 3, your Emerald Green Arborvitae can reach 6 to 8 feet tall, and by year 5, it may already be close to its mature height. Proper spacing is crucial—planting too close can stunt growth and lead to crowding issues.
| Age (Years) | Height Range (ft) | Width Range (ft) | Spacing (ft) |
|---|---|---|---|
| 1 | 2-3 | 1-1.5 | 4-6 |
| 3 | 6-8 | 2-2.5 | 6-8 |
| 5 | 10-12 | 3 | 8-10 |
| Mature (10+) | 12-15 | 3-4 | 10-12 |
For single specimens, aim for 8 to 10 feet of spacing from structures or other plants. When creating a privacy hedge, plant them 3 to 4 feet apart to allow for natural filling in. This spacing ensures your Arborvitae Emerald Green grows to its full potential without competition.
If you’re planting multiple rows, maintain 10 to 12 feet between rows to avoid overcrowding. Proper spacing also makes pruning and maintenance easier, reducing the risk of pests and diseases that thrive in dense, poorly ventilated areas.
In USDA Zones 3-7, this variety thrives with minimal care, but its growth rate can slow in shady conditions or poor soil. Amending the soil with organic matter and ensuring well-draining conditions will encourage faster, healthier growth.
With the right conditions, your Emerald Green Arborvitae will reach its mature height in 5 to 10 years, providing year-round greenery and privacy. Plan ahead by checking your landscape’s dimensions and ensuring adequate space for its full size.
