Fast Growing Privacy Trees
If you want to screen the neighbor’s yard, soften a property line, or create a green backdrop quickly, fast growing privacy trees are your best friends. Over the years I’ve planted dozens of hedgerows and single-row screens around my own garden and for friends, and I can tell you the right species planted well will give you a private sanctuary in a few seasons instead of a decade.
Why choose fast-growing privacy trees
Fast growers give you privacy sooner, shade faster, and can dramatically change the look and feel of your outdoor space in a short time. They’re especially useful when you need to block a view, reduce road noise, or create wind protection. But “fast” can mean trade-offs: some species need more maintenance, others have invasive roots, and a few are prone to disease if not cared for.
Top fast growers I recommend
Below are species I’ve used and observed perform consistently well. I include climates they tolerate and what to watch out for.
- Thuja ‘Green Giant’ — A hybrid arborvitae that grows rapidly, often two to three feet per year in good conditions. Evergreen, dense, and tolerant of many soils. Great for tall screens and low maintenance once established.
- Leyland Cypress — Extremely fast (sometimes over three feet per year), forms a dense, columnar screen. Works well in mild climates but can suffer from cypress canker in humid zones.
- Eastern White Pine — A soft, graceful evergreen that grows quickly and reaches tall heights. Good for a natural, woodland-style screen.
- Nellie R. Stevens Holly — An evergreen holly that grows quickly into a formal hedge. Attractive glossy leaves and red berries, and more disease resistant than some others.
- Green Giant Bamboo (clumping varieties) — Not a tree, but a rapid, year-round screen if you choose clumping types and manage spacing. Instant tropical look and excellent sound buffering.
- Austrian Pine and Certain Spruces — Fast in young years; good when you want a tall, wind-tough screen.
Evergreen or deciduous for privacy
For year-round privacy, evergreens win. Deciduous trees can grow fast but will lose leaves in winter, so plan layered planting (evergreen understory plus deciduous canopy) if you want screening in all seasons.
Choosing the right tree for your site
Match species to your climate, soil, and space. I always walk the planting line and check sunlight, drainage, and overhead wires before selecting trees.
- Sun exposure: Most fast growers prefer full sun; some tolerates part shade.
- Soil and drainage: Green Giant and Leyland adapt to a range of soils but avoid waterlogged spots unless you pick water-tolerant species.
- Space: Measure available width and height under power lines. Dense trees like arborvitae need spacing to avoid future crowding.
- Local pests and diseases: Ask local extension services about common issues like cypress canker or bagworms.
Planting and spacing for a quick, healthy screen
Proper planting and early care are the secret to getting privacy fast. I’ve lost more than one promising screen to poor planting technique, so here’s what I do now:
- Dig a hole twice as wide as the root ball but no deeper than the root ball’s height.
- Amend heavy clay with compost for better drainage and root development.
- Mulch well but keep mulch away from trunks to avoid crown rot.
- Water deeply and regularly the first two summers; frequent shallow watering creates weak roots.
- Space trees according to mature spread: give Arborvitae 3–5 feet for a tight hedge or 8–12 feet for specimen growth; Leyland cypress often goes 8–10 feet apart.
Pruning and maintenance
Pruning helps keep a screen dense and even. I lightly prune evergreens in spring to shape and remove dead wood. Heavier pruning should be done with care — many conifers don’t regrow from old wood.
Growth timelines you can expect
Every site is different, but here are rough expectations based on my experience:
- Fastest growers like Leyland and Green Giant: 2–4 feet per year under good conditions.
- Moderate fast growers like Nellie R. Stevens Holly: 1–2 feet per year.
- Bamboo (clumping): Can reach full screening height in 2–4 seasons if planted with adequate soil and water.
Potential downsides and how to avoid them
Fast-growing trees can have downsides, and I always mention these to clients before we plant:
- Root invasion — Don’t plant too close to foundations or septic systems; use root barriers if needed.
- Disease susceptibility — Monitor for fungal diseases; choose disease-resistant cultivars when possible.
- Maintenance — Fast growth means more pruning and occasional thinning to prevent toppling in storms.
- Neighbor and legal issues — Check local rules about hedge height and talk to neighbors before planting a tall screen.
I once planted a row of Leyland cypress without checking the drainage; three years later several trees declined from root rot. Replanting with Green Giants and improved drainage saved the screening—and taught me to never skip the soil test.
Fast-growing privacy trees for specific needs
Pick a species to match your priorities:
- For narrow spaces: Columnar arborvitae or narrow holly varieties.
- For windy sites: Pines and spruces with robust root systems.
- For deer resistance: Hollies and some pines are less palatable.
- For noisy roads: Dense evergreens and bamboo provide excellent sound buffering.
Final tips from a gardener
Planting a fast screen is rewarding but it’s a commitment. My best advice:
- Invest in good quality nursery stock — a healthy plant now saves years of grief.
- Water deeply in the first two summers and keep mulch refreshed.
- Think long-term about spacing and root safety near structures.
- Communicate with neighbors and check local rules.
With the right species and care, a fast-growing privacy screen will give you the green, quiet, private garden you want in just a few seasons. I still get a thrill the first time a new hedge fills in and I can relax with a cup of tea behind it—give it some care and it will become your favorite living wall.
