Privacy Trees: Space, Climate, Growth and Maintenance
The best privacy tree is the one that fits your space at full size, survives your winters and summers, and grows fast enough to block the view you care about. A tree that looks right in the nursery pot can outgrow a narrow side yard in a few years or struggle in the wrong climate. Measure first, check your hardiness zone, then compare species. Planting is often one part of a bigger yard project, which our landscaping project planning page covers.
Step 1: Measure Your Privacy Needs and Space
Before you pick a species, write down:
What you're blocking: a neighbor's window, a street, a deck. Note how high the screen needs to be, measured from where you sit or stand.
Length of the screen: the run along the fence or boundary, in feet.
Width available: the distance from the fence or property line to your lawn, patio or house. This is the limit on mature width.
Sun: hours of direct sun the spot gets in summer.
Year-round or summer only: evergreens screen all year; deciduous trees drop their leaves.
A small yard or a narrow side strip calls for a columnar tree that stays 2 to 5 feet wide. A large lot can take broad trees that spread 10 feet or more.
Step 2: Match the Species to Your Climate
Every tree has a range of hardiness zones where it survives typical winter lows. Find your zone on the 2023 USDA Plant Hardiness Zone Map (US, search by ZIP code) or Canada's Plant Hardiness Site. Zone is only half the picture: heat, humidity, drainage and soil also decide how well a tree does.
Step 3: Compare Growth and Upkeep
These are common evergreen choices for privacy screens. Sizes are typical mature ranges from university horticulture sources; individual trees vary with site and climate.

4–8 ft
Confirm for your zone
Ask locally
Dense, narrow, columnar form
Italian Cypress

Mites, bagworms, root rot in wet soil; full sun only
Thuja Green Giant
40–60 ft

Bagworms; root rot in poorly drained soil; not salt tolerant
Eastern Red Cedar

Bagworms, scale, cedar-apple rust (affects nearby apple trees); highly flammable
Leyland Cypress
60–70 ft
10–15 ft
6–10
Rapid, up to 3 ft a year when young
Prone to canker, root rot and bagworms; often lives only 20–50 years

A few patterns stand out:
Small yards and narrow strips: Sky Pencil Holly, Emerald Green Arborvitae and Spartan Juniper stay narrow. If Sky Pencil Holly struggles in your heat or soil, Spartan Juniper or Emerald Green Arborvitae are the usual alternatives for a similar slim shape.
Fast, tall screens on larger lots: Thuja Green Giant grows quickly but gets wide, so leave room.
Leyland Cypress: fast, but NC State Extension flags it as pest- and disease-prone and suggests considering alternatives.
Italian Cypress vs Emerald Green Arborvitae: both are narrow, but Italian Cypress grows far taller and suits warmer zones; Emerald Green suits colder ones.
For spacing, check the nursery tag or your local extension office. Trees planted closer than their mature width fill in sooner but compete for light and water.
The NC State Extension Gardener Plant Toolbox has full profiles for most of these species, including light, soil and pest details.
Step 4: Check Utility and Boundary Concerns
Underground lines: call 811 in the US, or your provincial one-call service in Canada, before you dig planting holes. It's free and marks buried gas, power and water lines.
Overhead lines: keep tall species well away from power lines. A tree that tops out at 40 to 70 feet doesn't belong under them.
Property line: plant far enough inside your boundary that the mature width stays on your side.
Local rules: some cities and homeowners associations limit hedge height or what can grow near sidewalks and driveways. Check before you plant.
Foundations and septic systems: keep large trees back from the house, and away from septic tanks and drain fields.
Step 5: Plan Removal of Existing Plants
New privacy screens often replace something: an overgrown hedge, dying shrubs, an old fence or a strip of sod. Plan where that material goes before planting day.
Branches and brush: many cities collect yard waste, but rules on bundling, length and pickup dates vary.
Stumps and roots: heavy, and not always accepted with regular yard waste.
Sod and soil: very heavy for their volume; ask about weight limits before loading a container.
Old fencing: keep treated wood separate from clean yard waste and ask how to dispose of it.
For a full row of shrubs, a fence and the sod beneath, a small dumpster rental takes it all in one go. Tell your operator if it includes soil, sod or stumps so the size and weight allowance match. Our page on renting a dumpster for yard waste covers what to expect.
Step 6: Ask a Qualified Local Source
Before you buy a full row of trees, confirm your shortlist with someone who knows your area:
Your county's Cooperative Extension office (US) or a provincial horticulture service (Canada)
A local, independent garden center that stocks trees grown for your climate
A certified arborist, for large trees or planting near structures and utilities
Ask about local pests, drainage, deer pressure and which species have done well in nearby yards. Once you've chosen the trees and know what's coming out, the next step is to prepare a landscaping project before seeking quotes.
