What You'll Learn
Cedar trees are one of the most reliable ways to create a natural privacy screen that lasts for decades. In this guide, you'll learn how to plant cedar trees for privacy — from picking the right variety for your climate to proper hole preparation, spacing, mulching, and long-term care. Whether you're a first-time planter or upgrading an existing landscape, this step-by-step guide gives you everything you need to get it right the first time.
Privacy is one of the top reasons homeowners invest in trees. Cedar trees offer year-round coverage, fast establishment, and a classic look that blends into almost any landscape. But planting them incorrectly — wrong spacing, wrong depth, wrong variety — leads to gaps, disease, and wasted money. This guide walks you through the entire process so your cedar hedge thrives from day one.
Choosing the Right Cedar Variety for Your Privacy Hedge
Not all cedars perform equally as privacy screens. The variety you choose will determine how tall your hedge grows, how dense it becomes, and how well it handles your local climate. Getting this decision right before you dig a single hole saves years of frustration.
Different cedar varieties vary significantly in density, height, and growth rate for privacy use.
Eastern Red Cedar vs. Western Red Cedar
Climate zone compatibility should drive your variety choice above everything else. Eastern Red Cedar (Juniperus virginiana) thrives in Zones 2–9 and handles drought, clay soil, and cold winters far better than most alternatives. It grows 40–50 feet tall and produces dense, dark green foliage that holds color year-round.
Western Red Cedar (Thuja plicata) performs best in the Pacific Northwest, where humidity and mild winters suit its needs. It grows faster than Eastern Red Cedar and reaches impressive heights, but it struggles in dry or cold inland climates. If you're in the Southeast, Midwest, or Northeast, Eastern Red Cedar is almost always the stronger choice.
Pro Tip
Check your USDA hardiness zone before purchasing any cedar variety. Planting a variety outside its recommended zone is the single most common reason cedar privacy hedges fail within the first two years.
Emerald Green Arborvitae and Other Cedar Alternatives
True cedars aren't the only option for a cedar-style privacy hedge. Emerald Green Arborvitae is one of the most popular compact alternatives, growing 12–14 feet tall with a tight, columnar shape. It fits smaller yards where full-size cedars would overwhelm the space or shade out neighboring plants.
Other compact cultivars worth considering include Thuja 'Smaragd' and Cryptomeria Radicans. These trees stay manageable in size while still delivering solid screening. If your yard is narrow or you're planting close to structures, compact varieties give you privacy without the maintenance headaches of a 50-foot tree.
Matching Cedar Growth Rate to Your Privacy Timeline
Fast-growing varieties like Thuja Green Giant can add 3–5 feet of height per year under ideal conditions. That speed is appealing, but fast growers often produce less dense branching in the early years. You'll get height quickly, but gaps can persist longer than expected.
Slower varieties like Eastern Red Cedar grow 1–2 feet per year but produce tighter, more effective screening over time. If you need privacy within two years, pair fast-growing trees with a temporary fence or trellis. If you're planning for the long term, slower varieties often deliver a more solid hedge by year five.
Preparing Your Planting Site for a Cedar Privacy Row
Proper site preparation is the single biggest factor separating thriving cedar hedges from struggling ones. Skipping this step leads to poor drainage, nutrient deficiencies, and uneven growth across your row. Take the time to prepare correctly, and your trees will reward you with rapid, uniform establishment.
A well-marked planting row with measured spacing ensures uniform coverage as cedars mature.
Soil Testing and Amendment Before Planting
Cedars tolerate a wide range of soil types, but they require adequate drainage to prevent root rot. Before planting, test your soil pH. Cedars prefer a pH between 6.0 and 7.5. Most university cooperative extension programs offer affordable soil testing kits — the University of Connecticut Soil Nutrient Analysis Laboratory is one example of a reliable resource for understanding your soil composition.
If your soil is heavy clay, work in coarse sand or organic compost to improve drainage. Sandy soils benefit from added compost to retain moisture during dry spells. Avoid adding excessive nitrogen at planting — it pushes soft, weak growth that's more vulnerable to wind damage and pests.
Spacing Guidelines for Maximum Privacy Coverage
Spacing is where most homeowners make their biggest mistake. Plant too far apart and you wait years for the canopy to close. Plant too close and you create competition that stunts growth and invites disease. For a solid privacy screen, follow these general guidelines:
| Cedar Variety | Mature Width | Recommended Spacing | Years to Screen |
|---|---|---|---|
| Eastern Red Cedar | 10–20 ft | 6–8 ft apart | 4–6 years |
| Thuja Green Giant | 12–20 ft | 5–8 ft apart | 3–5 years |
| Emerald Green Arborvitae | 3–4 ft | 2–3 ft apart | 3–4 years |
| Western Red Cedar | 15–25 ft | 8–10 ft apart | 5–7 years |

Sunlight and Wind Exposure Considerations
Cedars need at least six hours of direct sunlight per day to develop dense foliage. Shade from buildings or other trees causes thin, patchy growth on the shaded side — which defeats the purpose of a privacy hedge. Always observe your planting site at different times of day before committing to a location.
Prevailing wind direction matters too. A cedar row planted perpendicular to prevailing winds acts as a windbreak, which reduces noise and creates a more sheltered yard. Planting parallel to wind allows gusts to funnel through gaps. For more on this dual function, see our guide on privacy trees that double as windbreaks.
Step-by-Step Planting Process for Cedar Privacy Trees
Following a precise planting sequence reduces transplant shock and gives your cedar trees the best possible start. Each step below builds on the last — skipping any one of them increases the risk of establishment failure.
Correct hole width and root ball positioning are critical for healthy cedar establishment.
Dig the Planting Hole
Dig your hole two to three times wider than the root ball but no deeper than its height. Wide holes encourage lateral root spread, which anchors the tree and improves nutrient uptake. Narrow holes force roots to circle, leading to long-term instability.
Position the Root Ball
Place the root ball so the root flare — where the trunk widens at the base — sits at or just above ground level. Planting too deep is one of the most damaging and common mistakes. It restricts oxygen to the roots and causes slow decline that isn't visible until years later.
Backfill and Firm the Soil
Use the native soil you removed to backfill the hole. Avoid adding excessive amendments to the backfill — this can create a "bathtub effect" where water pools around the roots. Firm the soil gently to eliminate air pockets without compacting it.
Water, Mulch, and Stake
Water deeply immediately after planting to settle the soil. Apply 3–4 inches of mulch in a ring around the base, keeping it 3 inches away from the trunk. Stake only if the tree is in a high-wind location, and remove stakes after the first growing season to avoid girdling.
Warning
Never mound mulch against the trunk of your cedar tree. Mulch volcanoes trap moisture against the bark, promoting fungal disease and rot that can kill an otherwise healthy tree within a few seasons.
Ongoing Care to Maintain a Dense Cedar Privacy Screen
The first three years after planting determine the long-term density and shape of your privacy screen. Consistent care during this window locks in the structure you want. After establishment, cedars are surprisingly low-maintenance — but those early years require attention.
Pruning Techniques to Encourage Lateral Fullness
Strategic light trimming promotes outward branching rather than unchecked height. This is what creates true privacy — dense lateral growth that blocks sight lines at eye level. Prune in late winter or early spring before new growth begins. Remove only the tips of branches, never more than one-third of the tree's total foliage at once.
Avoid shearing cedars into tight geometric shapes unless you're maintaining a formal hedge. Heavy shearing creates a dense outer shell but kills interior branching, leaving the hedge thin and brown inside. Light selective pruning preserves interior growth and produces a fuller, healthier screen over time.
Fertilization and Seasonal Feeding Schedule
Cedars are not heavy feeders. Over-fertilizing is as harmful as neglecting them, pushing weak growth that's vulnerable to pests and wind damage. Apply a slow-release balanced fertilizer (10-10-10) in early spring just before new growth begins. One application per year is usually sufficient for established trees in average soil.
Avoid fertilizing after mid-summer. Late-season feeding pushes tender new growth that won't harden off before winter, increasing the risk of cold damage. If your soil test shows specific deficiencies, address those with targeted amendments rather than broad fertilizer applications. According to the Penn State Department of Plant Science, most established evergreens in residential landscapes need little to no supplemental fertilization once they're past the establishment phase.
Pro Tip
During the first growing season, water your cedar trees deeply once or twice per week. After the first year, reduce to once per week during dry periods. Deep, infrequent watering encourages deeper root development and makes your trees far more drought-resistant long-term.

The most common failures — poor variety selection, wrong planting depth, inadequate spacing, and inconsistent early watering — are all avoidable with the right information. Use this guide as your reference from site planning through the first growing season, and your cedar hedge will reward you with reliable, year-round privacy that improves with age.
Frequently Asked Questions
How long does it take for cedar trees to create a full privacy screen?
▼
Most cedar varieties produce a functional privacy screen within 3–6 years, depending on the variety and spacing. Fast-growing options like Thuja Green Giant can close canopy gaps in as little as 3 years when planted 5–6 feet apart. Slower varieties like Eastern Red Cedar may take 5–7 years to achieve full screening.
To accelerate your timeline, plant trees closer together, choose faster-growing varieties, and maintain a consistent first-year watering schedule. A temporary fence or privacy screen can fill the gap while your cedars establish.
Can cedar trees be planted too close to a fence or property line?
▼
Yes. Cedar roots spread 1.5 to 2 times the width of the canopy, which can eventually push against fence posts or cross property lines. Most local ordinances require trees to be planted at least 3–5 feet from property lines, though this varies by municipality.
Always check your local zoning regulations before planting. For fences, leave at least 3 feet of clearance to allow air circulation and prevent moisture buildup against the fence structure. Planting too close to a fence also limits your ability to access and prune the interior of the hedge.
Do cedar trees lose their privacy coverage in winter?
▼
True cedars and most cedar-type evergreens hold their foliage year-round, making them excellent for four-season privacy. Eastern Red Cedar, Thuja Green Giant, and Emerald Green Arborvitae all maintain green foliage through winter in their recommended hardiness zones.
Some varieties may show a slight bronzing of foliage in very cold climates during winter, but they do not drop their leaves. This is a natural protective response and reverses when temperatures warm in spring. Choose varieties rated for your hardiness zone to ensure consistent year-round coverage.
What pests or diseases most commonly affect cedar privacy hedges?
▼
The three most common threats to cedar privacy hedges are bagworms, spider mites, and cedar apple rust. Bagworms appear in summer and create spindle-shaped bags on branches — hand-pick them in late fall or treat with Bt (Bacillus thuringiensis) in early summer. Spider mites thrive in hot, dry conditions and cause stippled, yellowing foliage.
Cedar apple rust is a fungal disease that requires both cedar and apple trees to complete its life cycle. If you have apple trees nearby, monitor your cedars for orange gelatinous galls in spring. Early identification and removal of infected material prevents widespread spread. Inspect your trees at least twice per season — once in spring and once in late summer.
Is it better to plant cedar trees in spring or fall?
▼
Both seasons work well, but spring planting gives cedars a full growing season to establish roots before facing winter stress. In most regions, planting in early spring — after the last hard frost but before summer heat — gives trees the best start. Roots establish quickly in warm soil, and regular spring rainfall reduces your irrigation burden.
Fall planting works well in warmer climates (Zones 7–9) where winters are mild and soil stays workable. Cooler temperatures reduce transplant stress, and fall rains support root development without the heat stress of summer. In colder climates (Zones 4–6), fall planting carries more risk — trees may not establish fully before the ground freezes.
