How To
If you're eyeing the Arborvitae Emerald Green 🌲 for your yard, you're probably wondering just how tall these evergreens will grow—and whether they'll fit your space perfectly. At full maturity, they reach an impressive 12–15 feet, making them a top choice for privacy screens and hedges, but their growth rate might surprise you.
These shrubs grow 6–12 inches per year, so in just a decade, you could see them towering over your fence. The key to their success? Planting them in well-draining soil with plenty of sunlight, especially in USDA Zone 6a, where they thrive best. But don’t worry—with the right care, you can easily shape them to fit your landscape.
Whether you're planning a cozy backyard retreat or a bold privacy barrier, understanding their growth habits is the first step. I’ll break down everything you need to know—from spacing tips to pruning tricks—to keep your Arborvitae Emerald Green looking its best without overpowering your yard.
Let’s dive into how to harness their natural growth (or rein it in) for a landscape that’s both stunning and functional. Ready to get started?
Arborvitae Emerald Green height by year: growth chart and mature size
Understanding the Arborvitae Emerald Green growth rate helps you plan your landscape design effectively. This evergreen shrub grows at a moderate to fast pace, reaching its mature height of 12–15 feet within 10–15 years. Unlike slower-growing varieties, Emerald Green Arborvitae can add 6–12 inches per year under ideal conditions, making it perfect for privacy screens or hedges.
When planting, consider the final height to avoid overcrowding. In small yards, spacing 3–4 feet apart ensures proper airflow and light penetration. For larger properties, you can space them 5–6 feet apart to create a denser screen. The width typically reaches 3–4 feet, so plan accordingly for a balanced look.
Environmental factors like sunlight exposure, soil quality, and water availability significantly impact growth speed. For example, plants in full sun with well-draining soil grow faster than those in shady or compacted soil. In USDA Zones 3–8, these shrubs thrive, but colder climates may slow early growth.
Here’s a quick reference for Arborvitae Emerald Green height progression by year to help you visualize growth:
| Year | Average Height (ft) | Growth Rate (in/year) | Notes |
|---|---|---|---|
| 1 | 1–2 ft | 12–24 in | Establishment phase |
| 3 | 6–8 ft | 24–36 in | Rapid vertical growth |
| 5 | 8–10 ft | 12–24 in | Fills out width |
| 10+ | 12–15 ft | 6–12 in | Mature height reached |
For privacy screens, aim to plant Arborvitae Emerald Green 3–4 feet apart to achieve a dense, unbroken barrier by maturity. If you’re using them as specimen plants, space them 6–8 feet apart to highlight their columnar shape. Always check local frost dates, as early planting in spring (April–May) ensures robust root development before winter.
In urban gardens with limited space, consider pruning techniques to control height. For example, a light annual trim in late winter can maintain a 6–8 foot height, ideal for smaller yards. However, avoid heavy pruning, as this can stress the plant and reduce its disease resistance.
One common misconception is that Arborvitae Emerald Green grows evenly in all directions. In reality, they grow faster upward than outward, which is why they’re excellent for vertical landscaping. If you notice uneven growth, it may indicate poor soil nutrition or inconsistent watering. Adjusting your care routine can help correct this.
To encourage optimal growth, mulch around the base with organic matter like wood chips. This retains moisture, regulates soil temperature, and suppresses weeds that compete for nutrients. Avoid piling mulch directly against the trunk, as this can cause rot over time.
If you’re planting multiple rows for a privacy hedge, stagger the plants to create a natural, layered look. This not only improves aesthetics but also ensures better light penetration to the inner plants. For best results, plant in early spring or fall, when temperatures are mild and root establishment is easier.
Remember, the mature height of Arborvitae Emerald Green is just a guideline. With proper care, some plants may exceed 15 feet, while others in less-than-ideal conditions may stay shorter. Regular monitoring and adjustments to your care routine will help you achieve the desired height for your landscape goals.
Arborvitae Emerald Green height by year: growth chart and mature size
Understanding the Arborvitae Emerald Green growth rate helps you plan your landscape design effectively. These evergreens are known for their fast growth, typically reaching 12–15 feet tall at maturity. Their narrow, upright form makes them ideal for privacy screens and hedges, but proper spacing is key to avoid overcrowding.
In their first year, these shrubs grow 1–2 feet tall, establishing a strong root system. By year two, they can double in height, reaching 3–5 feet. This rapid early growth slows slightly as they mature, but they’ll still add 6–12 inches annually in ideal conditions.
| Year | Height Range (ft) | Width (ft) | Growth Rate (in/year) |
|---|---|---|---|
| 1 | 1–2 | 1–1.5 | 12–24 |
| 2 | 3–5 | 2–3 | 24–36 |
| 3 | 6–8 | 3–4 | 12–24 |
| 5 | 8–10 | 3–4 | 6–12 |
| 10+ | 12–15 | 3–4 | 3–6 |
Several factors influence their final height, including sunlight exposure, soil quality, and watering habits. For example, plants in full sun with well-draining soil grow faster than those in shade or compacted soil. Regular pruning can also shape their height, especially if you’re using them for hedges or narrow privacy screens.
If you’re planting Arborvitae Emerald Green as a privacy screen, space them 3–5 feet apart to allow for their mature width of 3–4 feet. This spacing ensures they fill in quickly without competing for nutrients. For smaller landscapes, consider planting them in containers or using root barriers to control their spread.
In colder climates (USDA Zones 3–7), these shrubs grow more slowly but still reach their mature height over time. Their drought tolerance once established means they won’t require constant watering, but young plants need consistent moisture to support their rapid growth.
For a quick reference, Arborvitae Emerald Green typically surpasses a standard basketball hoop (10 ft) by maturity, making them a dominant feature in any landscape design. Whether you’re aiming for a tall hedge or a statement plant, understanding their growth pattern helps you achieve the perfect look.
