Best Privacy Trees: Green Giant vs. American Pillar (Plus Redbud, Dogwood, Oak & Maple for Curb Appeal)

Want fast, year-round screening that looks great and handles KC's weather? Two arborvitae lead the pack—Green Giant and American Pillar—and they pair perfectly with Redbud, Dogwood, Oak, and Maple for curb appeal. Below you'll find spacing, siting, watering, HOA tips, and a quick care plan. Our installs are auger-drilled and include a 1-year establishment warranty with a simple care agreement.

What Makes a Great Privacy Tree in KC?

• •
  Heat & wind tolerance: Summers get hot and gusty; choose trees that hold needles/foliage through stress.
• •
  Clay soils: Many Northland lots have compacted clay; proper hole prep and mulch rings help roots breathe.
• •
  Winter burn: Evergreen foliage can desiccate in cold winds—consistent fall watering and mulch reduce risk.
• •
  Deer pressure: Varies by neighborhood. Fencing during establishment helps where browsing is heavy.
• •
  Maintenance: Favor trees with predictable shape and minimal shearing needs for long, uniform screens.

Green Giant vs. American Pillar: Side-by-Side

Growth Rate & Mature Size

• •
  Green Giant Arborvitae (Thuja 'Green Giant'): Fast grower; commonly 25–35′ tall, 8–12′ wide at maturity in KC.
• •
  American Pillar Arborvitae (Thuja 'American Pillar'): Fast grower; 20–30′ tall but narrow—typically 3–5′ wide.

Shape, Spacing, and Setbacks

• •
  Green Giant: Naturally conical; great for big yards and curving property lines.

  • Typical spacing for a solid screen: 5-7′ on center (can stagger at 7′/10′).
• •
  American Pillar: Columnar form that saves space in narrow side yards.

  • Typical spacing for a solid screen: 4–5′ on center.
• •
  Setbacks: Keep trunks 3–5′ off fences for airflow and maintenance; more if snow drifting is common.

Sun, Soil, and Irrigation Needs

• •
  Full sun to light shade (6+ hrs preferred).
• •
  Plant in well-prepped clay with a broad, shallow hole and loosened sidewalls; avoid burying the root flare.
• •
  Drip or watering bags are strongly recommended for the first two seasons.

Pros/Cons for Narrow Lots vs. Big Yards

• •
  Narrow lots: American Pillar wins (tight footprint, quick coverage).
• •
  Big yards / long lines: Green Giant wins (wider base, strong wind presence, softer natural lines).

Spacing Guide for Privacy Rows (Quick Chart)

We confirm spacing on a site walk based on wind exposure, HOA rules, and your long-term maintenance plan.

Planting the Right Way (Why Auger-Drilled Wins)

• •
  Correct depth & root flare: Set the flare at finished grade—never below.
• •
  Wide, shallow hole: We auger wider than deep to loosen sidewalls and help lateral roots spread.
• •
  Mulch ring: 2–3″ deep, pulled 2–3″ back from the trunk; no "volcano mulching."
• •
  Watering bag or drip line: Slow, deep watering beats daily spritzing.
• •
  Staking: Only if needed for wind; remove within the first growing season.

Alternatives That Complete the Look

Redbud & Dogwood (Four-Season Interest)

• •
  Eastern Redbud (Cercis canadensis): Spring bloom, heart-shaped leaves—great near entries.
• •
  Flowering Dogwood (Cornus spp.): Layered branching and seasonal color.

Oaks & Maples (Shade / Street Frontage)

• •
  Oaks (Bur, Swamp White, Shumard): Long-lived structure trees with strong canopies.
• •
  Maples (select urban-tough cultivars): Color and canopy where shade is needed.

Layered Screening = Best of Both

Mix an evergreen spine (American Pillar or Green Giant) with ornamental accents (Redbud/Dogwood) and a shade anchor (Oak/Maple) for privacy and curb appeal.

HOA & New-Build Tips (Northland Focus)

• •
  Briarcliff, Riverside, Liberty: Submit simple plans with species, spacing, and setbacks.
• •
  Golf-course communities: Keep sightlines open near cart paths and intersections.
• •
  Photo verification: Take "before," "install," and "finished" photos for quick approvals and records.
• •
  Utilities: Call 811 before augering; respect easements and property lines.

Care Agreement Basics (for the 1-Year Establishment Warranty)

Weeks 1–2:

Water every 2–3 days (deep soak) using drip or a watering bag; check soil 4–6″ down.

Weeks 3–8:

Water 2×/week unless rain is ≥1″ that week; maintain mulch ring at 2–3″ depth.

Summer Heat Events (90°F+):

Add one extra deep soak; watch for flagging foliage.

Fall Prep:

Keep watering until the ground cools—evergreens store water for winter.

Common Mistakes to Avoid:

Burying the root flare, over-mulching, daily light watering (stay with deep soaks), letting turf grow up to the trunk.
