If you're planting an arborvitae and wondering how tall do arborvitae grow each year, the answer might surprise you—some varieties shoot up 3 feet annually while others barely budge. This growth difference isn’t just about patience; it’s about choosing the right type for your space and giving it the care it craves.
The Green Giant arborvitae, for example, is a powerhouse, often reaching 12 feet in just 10 years, while the Emerald Green grows a modest 6 inches per year. Knowing these rates helps you plan your landscape with confidence, whether you’re creating a privacy screen or a cozy hedge. Let’s dive into the specifics so you can pick the perfect fit for your yard.
But growth isn’t just about the variety—soil quality, sunlight, and pruning play huge roles. A well-drained, nutrient-rich spot with morning sun can boost growth by up to 50%, while poor conditions might stunt even the fastest growers. We’ll cover the best practices to help your arborvitae thrive from day one.
Ready to turn your garden vision into reality? By the end of this guide, you’ll know exactly which arborvitae to plant, how fast they’ll grow, and the simple steps to keep them reaching for the sky—without the guesswork.
Arborvitae growth rates by variety: fastest vs slowest growers
Choosing the right arborvitae variety can make or break your landscape timeline. Some varieties like the Green Giant shoot up 3 feet annually in ideal conditions, while others like Emerald Green grow just 6 inches per year. This difference isn’t random—it’s rooted in genetics and care practices. Let’s explore the growth rates that will shape your garden’s future.
The Green Giant is the undisputed champion of speed, often reaching 12 feet in just 10 years. This makes it perfect for quick privacy screens or windbreaks. On the other end of the spectrum, dwarf varieties like Golden Globe top out at 3-4 feet after years of slow, steady growth. Understanding these rates helps you set realistic expectations and plan your space accordingly.
But growth isn’t just about height—it’s also about width. The American Plumosa, for example, grows 1-2 feet per year but spreads 3-4 feet wider annually, creating a bushy, rounded shape. This makes it ideal for hedges or foundation plantings where width matters as much as height. Let’s compare the most popular varieties so you can pick the perfect fit for your yard.
If you’re planning a privacy screen, the Green Giant is your best bet—it grows 3 feet per year and can reach 40 feet in just 10-12 years. This rapid growth means you’ll see results within a few seasons, making it ideal for homeowners eager to block noise or winds. For a more manicured look, the Emerald Green is a classic choice, growing steadily at 6-12 inches annually.
For smaller spaces, dwarf varieties like Golden Globe are perfect—they grow only 2-4 inches per year but stay compact, making them ideal for containers or tight garden beds. Their slow growth means less maintenance, but they’ll never tower over your patio or driveway. Choose wisely based on your space and timeline!
One surprising factor is how soil quality affects growth. Even the fastest-growing varieties like Green Giant can slow to a crawl if planted in poorly draining soil or shady spots. Rich, well-draining soil with morning sun can boost growth by 50% or more. We’ll cover the best planting practices in the next section to help you maximize your arborvitae’s potential.
Pro tip: If you’re planting multiple arborvitae for a hedge, space them 3-5 feet apart depending on the variety. This gives them room to grow without competing for nutrients, ensuring each plant reaches its full height potential. For example, Emerald Green hedges should start 3 feet apart, while Green Giant needs 5 feet of space to avoid overcrowding.
Remember, these growth rates are averages. Factors like climate, watering, and pruning can tweak them significantly. A Green Giant in a hot, dry climate might grow slower than one in a cooler, moist region. Pay attention to your local conditions and adjust your expectations accordingly.
Now that you know which varieties grow fastest, let’s dive into how to maximize their growth with the right care—so you can get that stunning privacy screen or hedge even sooner! 🌲
How to maximize arborvitae growth yearly: pruning, soil, and sunlight tips
Now that you know which arborvitae varieties grow fastest, let’s focus on how to boost their annual growth by up to 50% with the right care. The key factors are soil quality, sunlight exposure, and pruning techniques. Even the slowest growers like Emerald Green can thrive with proper attention, while fast growers like Green Giant will reach their full potential sooner.
Start with well-draining soil—arborvitae hate soggy roots. Amend heavy clay with compost or sand to improve drainage. A pH between 6.0 and 7.5 is ideal. Test your soil before planting; if it’s too acidic, add lime to create the perfect environment for root development. Healthy roots mean faster growth above ground!
Sunlight is another game-changer. While arborvitae tolerate partial shade, they grow 20-30% faster in morning sun. Avoid planting them in deep shade, where growth can stall entirely. If your yard has limited sun, choose shade-tolerant varieties like Emerald Green, but expect slower growth rates.
Pruning is often misunderstood—doing it wrong can stunt growth. The best time to prune is late winter or early spring, before new growth begins. Use clean, sharp shears to make cuts just above a leaf bud. Avoid over-pruning, which can leave your arborvitae vulnerable to pests and disease. For hedges, shape them gradually over time rather than cutting back drastically all at once.
Fertilizing can give your arborvitae a growth boost, but timing matters. Apply a balanced fertilizer (5-10-10) in early spring and again in mid-summer. Avoid fertilizing in fall or winter, as this can encourage tender new growth that won’t survive frost. For container-grown arborvitae, use a slow-release fertilizer to maintain steady nutrition.
Watch for common growth inhibitors like compacted soil or poor air circulation. If your arborvitae is planted too closely to a fence or building, it may grow unevenly. Space them 3-5 feet apart for proper airflow, which reduces disease risk and encourages even growth. Mulch around the base with wood chips to retain moisture and regulate soil temperature.
With these tips, your arborvitae will grow healthier and faster than ever. Whether you’re aiming for a tall privacy screen or a manicured hedge, the right care makes all the difference. Next, we’ll explore how long it takes for each variety to reach its full height—so you can plan your garden timeline with confidence! 🌿
