If you’ve ever dreamed of a towering 🌲 Cedar Tree in your yard, you might be surprised by just how tall these evergreens can grow—some varieties stretch toward the sky like natural skyscrapers! The answer to how tall can cedar trees grow depends on the species, but with the right conditions, they can reach heights that’ll make your neighbors jealous.
Picture this: a 40-foot Eastern Red Cedar standing sentinel in your landscape, its fragrant needles providing year-round shade and privacy. But not all cedars are giants—some stay compact, perfect for smaller spaces. Whether you’re planning a privacy screen or a statement piece, knowing the growth potential of each variety is the key to making it work in your yard.
Fast-growing cedars like the Atlas Cedar can add 2-3 feet per year, while slower varieties take decades to reach their full height. The good news? With smart spacing and occasional pruning, you can control their growth—even in tight spaces. Let’s break down the heights, growth rates, and space-saving tips so you can pick the perfect cedar for your vision.
Ready to transform your outdoor space? We’ll cover everything from dwarf varieties for small gardens to towering giants for bold landscapes—plus how to keep them healthy no matter their size. Let’s get started!

Cedar Tree height guide: species comparison and mature size expectations
When planning your landscape, knowing how tall cedar trees grow is essential—especially since some varieties can dwarf your entire backyard! Cedar trees span a dramatic range, from 8-foot dwarf varieties to towering 40-foot giants. The species you choose will determine not just height but also growth rate, spacing needs, and even your yard’s overall aesthetic.
For example, the Eastern Red Cedar (Juniperus virginiana) is a North American classic that can reach 30-40 feet at maturity, while the Atlas Cedar (Cedrus atlantica) grows even taller—up to 50 feet—with a faster growth rate. Meanwhile, compact options like 'Green Spire' stay under 15 feet, making them ideal for small yards or container gardening.
Here’s the key: spacing matters. A 40-foot cedar needs at least 20-30 feet of clearance from structures, power lines, and other trees to avoid root competition and future pruning headaches. Always check your local setback requirements before planting near property lines.

Fastest-growing Cedar varieties for quick privacy or shade solutions
If you’re looking for fast-growing cedar trees to create instant privacy or shade, you’ll love these varieties that can add 2-3 feet per year—some even faster! The Atlas Cedar leads the pack with its rapid growth rate, while 'Green Spire' offers a compact yet speedy option for smaller spaces. These trees are perfect for homeowners who want results without the decades-long wait.
For quick privacy screens, the Atlas Cedar is my top pick—it can reach 10-15 feet in just 5 years, making it ideal for blocking nosy neighbors or wind. If you’re working with limited space but still want height, the 'Emerald Sentinel' grows 1-2 feet annually while staying under 15 feet, perfect for narrow yards or container gardening.
Here’s the secret to accelerated growth: plant in well-draining soil with full sun exposure, and avoid overwatering. Cedar trees thrive in drought conditions, so once established, they’ll grow faster with minimal care. Just be patient—even the fastest varieties need a few years to reach their full potential.
-
Atlas Cedar: 2-3 ft/year, reaches 40-50 ft in 15-20 years. Best for bold landscapes and fast shade.
-
'Emerald Sentinel': 1-2 ft/year, stays under 15 ft. Ideal for containers or small yards.
-
Eastern Red Cedar: 1-2 ft/year, reaches 30-40 ft in 20-30 years. Great for wildlife habitats.
-

Pro tip: If you’re planting multiple cedars for a privacy screen, space them 3-5 feet apart to encourage faster, denser growth. Mulch around the base to retain moisture and suppress weeds, which can slow down early growth. With the right variety and care, you’ll have your dream cedar hedge in no time!
Remember, even the fastest-growing cedars need time to mature. The Atlas Cedar might be the quickest, but it still takes 15-20 years to reach its full height. Plan ahead, and you’ll enjoy years of shade, privacy, and that classic cedar aroma.
