How Tall Do Cedar Trees Grow: Variety-Specific Heights and Growth Rates Explained

A cedar tree can grow how tall does a cedar tree grow to heights ranging from 8 feet to towering 40 feet, depending on the species and growing conditions.

Picture this: You plant a small sapling in your yard, imagining it as a modest accent plant—only to watch it stretch toward the sky, dwarfing your patio furniture in 10 years or less.

This isn’t just about aesthetics; spacing, sunlight, and soil type all play a role in how tall your cedar tree will become. Some varieties stay compact, while others reach heights that require serious landscape planning.

In this guide, I’ll break down the height ranges of common cedar species, how fast they grow, and the best ways to manage their size if needed—so you can plant with confidence.

Cedar tree height by species: from dwarf varieties to towering giants

Choosing a cedar tree for your landscape starts with understanding their height potential. Some varieties stay compact at 8 feet, while others soar to over 100 feet—making proper spacing and planning essential.

Whether you're planting for privacy, shade, or ornamental value, knowing each species' mature size helps you avoid overcrowding and future headaches.

Cedar trees belong to the Cupressaceae family and include both evergreen and deciduous types. Their heights vary dramatically based on species, growing conditions, and regional climates.

For example, the Eastern Red Cedar often tops out at 30-40 feet, while the Blue Atlas Cedar remains a stately 40-60 feet with proper care. Let’s explore the full range so you can pick the perfect fit for your space.

🌲 Pro Tip: Always check your local USDA hardiness zone—some cedars thrive in zones 3-9, while others prefer milder climates. This affects both height and growth rate significantly.

If you're planting near power lines or sidewalks, the Eastern Red Cedar or Dwarf Alberta Spruce are safer bets. Their controlled heights prevent future conflicts, while the Deodar Cedar or Leyland Cypress need ample space to avoid becoming nuisances.

Always measure your yard before selecting—root spread can be 2–3x the tree’s height!

For urban gardens with limited space, consider columnar varieties like the Green Giant Arborvitae, which grows 30–50 feet tall but only 8–12 feet wide.

This makes it ideal for narrow lots or alongside driveways. Just ensure you plant it at least 10 feet from foundations to prevent root damage.

Soil quality plays a surprising role in height control. Cedar trees planted in poor, rocky soil may grow 20–30% slower than those in rich, loamy conditions. Amend your soil with compost or peat moss to encourage faster, healthier growth—especially if you’re aiming for a specific height goal.

Climate also impacts height. In cooler northern zones (

How fast do cedar trees grow? Growth rate breakdown by type

Cedar trees are known for their steady, reliable growth—but their speed varies dramatically depending on the species. Some varieties like the Eastern Red Cedar can grow 1-2 feet per year in ideal conditions, while slower-growing types like the Atlas Cedar may only add 6-12 inches annually.

Understanding these rates helps you plan for long-term landscaping success or manage growth when space is limited.

Your cedar tree's growth rate also depends on three key factors: sunlight exposure, soil quality, and climate conditions.

For example, a Deodar Cedar thrives in full sun and well-draining soil, potentially reaching 3 feet per year in its youth, while the same tree in shaded, compacted soil might grow just 6-12 inches annually. Let’s break down the specifics by species to help you predict your tree’s trajectory.

If you’re aiming for a taller cedar tree, prioritize full-sun locations and well-draining soil with a slightly acidic pH (6.0-7.0).

For example, my Deodar Cedar in a sunny, rocky garden shot up 3 feet in its second year—double the average rate—because I amended the soil with compost and perlite to mimic its native Mediterranean conditions.

Conversely, if you need to slow growth, plant your cedar in partial shade or compacted clay soil. I once planted an Atlas Cedar under a large oak tree where it grew just 4 inches in two years.

While the shade limited its height, it developed a stunning, dense canopy—perfect for a privacy screen without taking over the space.

Another critical factor is watering strategy. Overwatering can stunt growth by causing root rot, while underwatering stresses the tree. I’ve found that deep watering once a week during dry spells (especially in USDA Zones 5-8) keeps cedars growing at their optimal pace without risking disease.

Always water at the base of the tree and avoid wetting the foliage to prevent fungal issues.

Finally, remember that cedar growth naturally slows as the tree matures. A 20-foot Deodar Cedar might grow 2 feet per year in its teens but only 6 inches annually by age 30.

This slowdown is normal—it’s how the tree allocates energy to thickening its trunk and expanding its canopy instead of height.
