Landscaping
A cedar tree privacy fence transforms your yard into a serene retreat by muffling traffic noise and softening harsh winds—nature’s answer to noisy neighbors and drafty spaces.
I planted mine along the north side of my property, and within five years, they grew into a lush, wind-resistant barrier that feels like stepping into a forest.
The key isn’t just dropping seeds and hoping for the best—it’s spacing them 3-5 feet apart so they grow together without competing for sunlight.
The beauty of cedars is how low-maintenance they are once established. They thrive in full sun to partial shade, tolerate poor soil, and resist most pests, which means less work for you.
Just mulch the base to keep moisture in and weeds out, and prune lightly to shape them—no heavy-handed trimming needed. Over time, their rich, earthy scent and dense foliage create a living wall that’s both functional and stunning.
By year three, you’ll start seeing the real payoff: a 10-foot-tall screen that blocks views, deadens sound, and adds value to your home. The evergreen needles stay vibrant all winter, so your privacy never takes a break.
Pair them with ground covers like creeping thyme or ornamental grasses to soften the base and complete the look.
This works for urban backyards, suburban lots, or rural properties—just adjust spacing for faster or slower-growing varieties. The only mistake I see beginners make? Planting them too close together, which leads to stunted growth. Give them room to breathe, and they’ll reward you for decades.

Step-by-Step instructions for planting a cedar tree privacy screen
Here’s how to create a lush, wind-blocking screen with minimal upkeep—just follow these simple steps.
Choose and Prepare the Planting Site
Select a location with full sun to partial shade and well-draining soil. Cedar trees thrive in USDA zones 3-7, so check your local climate. Mark a straight line with stakes and string to ensure even spacing—6-8 feet apart for mature growth. Avoid low-lying areas where water pools, as cedars dislike soggy roots.
Test the soil by digging a 6-inch hole—if it feels compacted, mix in 2-3 inches of compost or sand to improve drainage. I always dig a trench along the line first to check for buried rocks or roots that could disrupt planting.
Dig Holes and Plant the Cedar Saplings
Dig holes twice as wide and deep as the root ball—typically 12-18 inches deep. Gently remove each sapling from its container, loosen tangled roots, and place it in the hole so the top of the root ball sits 1-2 inches below soil level. This prevents stem rot from settling soil.
Backfill with native soil, tamping lightly every 2 inches to eliminate air pockets. Water deeply to settle the soil around roots. I like to add a mulch ring 3 inches deep (but not touching the trunk) to retain moisture and suppress weeds.
Space and Stagger for Optimal Growth
Plant saplings in a staggered pattern—like bricks—to create a denser screen faster. For a 6-foot-tall screen, space them 6-8 feet apart; for 8-10 feet tall, reduce spacing to 4-6 feet. This ensures branches fill gaps naturally over time.
Water each sapling with 1-2 gallons of water immediately after planting. Check soil moisture weekly—cedars need 1 inch of water per week, but adjust for rain. Avoid overhead watering to prevent fungal diseases.
Prune and Maintain for a Dense Screen
Prune in early spring before new growth starts. Remove 1/3 of the tallest branches to encourage bushier growth. Cut just above a leaf bud or side branch to promote healing. Avoid heavy pruning in fall, as cedars need foliage to store nutrients for winter.
Fertilize lightly in early spring with a balanced 10-10-10 formula (follow package rates). Cedar trees generally don’t need much—over-fertilizing can burn roots. Monitor for pests like bagworms or spider mites; treat with horticultural oil if needed.
Monitor and Adjust for Long-Term Privacy
Check spacing annually—cedars grow 1-2 feet per year. Thin out crowded saplings in early spring if branches overlap. For a faster screen, consider planting a mix of fast-growing varieties like *Thuja occidentalis ‘Smaragd’ alongside slower types.
By year three, your screen should block 90% of wind and noise. Mulch annually to retain moisture and suppress weeds. With minimal care, your cedar privacy fence will thrive for decades.
Tips & tricks for planting a cedar tree privacy screen
A few key strategies will help your cedar privacy screen grow into a lush, wind-blocking barrier with minimal effort. The details in these steps make all the difference between a patchy screen and a dense, natural privacy wall.
Soil Preparation Matters: In Step 1, when you're digging that 6-inch test hole, pay special attention to drainage. If your soil feels compacted, don't just add compost—mix in coarse sand or perlite to create air pockets. Cedar roots need both moisture and oxygen, and this simple adjustment prevents root rot that can kill saplings. I've seen cedars planted in pure clay soil struggle for years, while those with amended soil thrive from day one.
Root Ball Placement Technique: The 1-2 inches below soil level recommendation in Step 2 is crucial for preventing stem rot. Many beginners plant with the root ball flush with the ground, which traps moisture against the trunk. Use a level to ensure consistent depth across all saplings. Pro tip: Gently wiggle the sapling after planting—if it moves more than 1/4 inch, you haven't backfilled tightly enough.
Watering Strategy: Those 1-2 gallons of water immediately after planting aren't just for settling soil—they're establishing root contact with the surrounding earth. In Step 3, I recommend watering again after 3-4 days to encourage root growth. Use a soaker hose placed at the drip line (not the trunk) to deliver water directly to the root zone where it's needed most. This targeted approach prevents fungal diseases while ensuring deep water penetration.
Pruning Insight: When you're removing that 1/3 of tallest branches in Step 4, focus on branches that are growing inward or crossing. These are the ones that create weak points and invite pests. Cut just above a leaf bud that faces outward to promote healthy growth. I've found that cedars pruned this way develop denser foliage within just two growing seasons compared to random pruning.

Frequently asked questions
Got questions about cedar tree privacy fences?
You’re not alone! Here are some of the most common inquiries—plus straightforward answers to help you plan with confidence.
How long does it take for a cedar tree fence to grow to full privacy height?
A well-maintained Thuja (cedar) hedge typically reaches 10–15 feet tall in 5–10 years, depending on variety (e.g., Green Giant matures faster than Emerald Green). For quicker privacy, plant trees 3–4 feet apart and prune annually to encourage dense growth. Pro tip: Use fast-growing cultivars like Thuja occidentalis ‘Smaragd’ for quicker results!
Are cedar tree fences more expensive than wood or vinyl privacy screens?
Upfront costs vary: Cedar trees average $2–$5 per plant (plus installation), while a 6-foot wood fence runs $15–$30 per linear foot. However, cedar trees save money long-term—no replacement needed for decades, and they add property value. Vinyl screens (another alternative) cost $10–$25 per linear foot but lack natural beauty and environmental benefits.
Do cedar trees survive harsh winters or drought?
Cedar trees are hardy in USDA Zones 3–8 and thrive in full sun to partial shade. Once established (after 1–2 years), they’re drought-tolerant—just water deeply during the first growing season. Winter care: Mulch the base to protect roots, and avoid heavy pruning in late fall (wait until early spring).
How often should I prune a cedar tree privacy fence?
Prune twice a year for the best shape: Light trimming in late spring (after new growth appears) and a heavier cut in early summer (before fall). Use sharp, clean shears to avoid damaging branches. Pro tip: Never cut more than ⅓ of the tree’s height at once—this stresses the plant and invites pests. Shape with a handheld hedge trimmer for uniformity.
Are cedar trees prone to pests or diseases?
Cedars are naturally resistant to most pests, but watch for bagworms, spider mites, or cedar bark beetles in dry conditions. Prevent issues by keeping trees healthy (water deeply, mulch well) and inspecting foliage regularly. Treatment: Spray with horticultural oil for mites or use neem oil for early-stage infestations. Fun fact: Their aromatic foliage often repels deer and rabbits!
Can I mix cedar trees with other plants for a layered privacy screen?
Yes! Combine cedars with evergreen shrubs like Arborvitae or Juniper for texture, or add climbing vines (e.g., Clematis) to the base for year-round coverage. Design tip: Plant taller species (12+ ft) at the back and shorter ones (3–6 ft) in front to create depth. Just ensure all plants share similar water and sun needs!
Wrapping up and next steps
A cedar tree privacy fence is more than just a boundary—it’s an investment in serenity, security, and curb appeal. Whether you’re shielding your yard from noise, wind, or prying eyes, these evergreen screens offer natural beauty and lasting durability.
With the right planning and care, you’ll enjoy a peaceful outdoor space for years to come!
