Green Giant Arborvitae Spacing for Privacy Screens

For most Green Giant arborvitae privacy screens, a useful starting point is about 5 to 6 feet apart, measured from the center of one tree to the center of the next. That spacing gives the trees room to develop while allowing neighboring Green Giants to grow together into a continuous evergreen screen.

That does not mean every property should automatically use the same spacing. The right layout depends on the length of the row, how quickly the customer wants the screen to fill in, available planting space, the view being blocked, site access, and the long-term size of the trees.

If you are still deciding whether Green Giants are the right species for the job, start with Best Privacy Trees for Pennsylvania Properties. If Green Giants are already the plan, spacing is one of the most important decisions to make before planting.

For a typical privacy row, approximately 5 to 6 feet on center is a practical planning range. “On center” means measuring from the center of one trunk to the center of the next trunk, not from the outer foliage or the edge of the root ball.

At that distance, the trees remain separate when first planted but have room to broaden and eventually overlap visually as the screen matures. It is close enough to create a unified row without treating Green Giants like a narrow formal hedge.

The final layout should still be adjusted to the property. Big Green Giants reviews the planned locations with installation customers before planting and finalizes the layout based on the actual site. The company’s full process is explained in Green Giant Arborvitae Delivery & Installation.

Spacing changes both the short-term appearance and the long-term behavior of a privacy screen.

Planting more closely can make the row feel denser sooner, but it also uses more trees and gives each tree less room as the planting matures. Wider spacing lowers the number of trees required and gives each Green Giant more individual room, but the gaps between trees remain visible longer.

That creates a basic planning tradeoff:

Closer spacing: more trees, higher initial cost, and faster visual overlap.

Wider spacing: fewer trees and more room per tree, but a longer wait for a continuous screen.

Moderate spacing: balances tree count, development space, and the time needed for the row to fill in.

For most homeowners, the goal is not to force the trees together as quickly as possible. It is to create a privacy row that works visually now and still has enough room to develop well over time.

Once you know the approximate length of the area you want to screen, spacing gives you a quick way to estimate tree quantity. The numbers below are rough planning figures, not a final site layout.

Actual quantities can change once the row is positioned on the property. Corners, endpoints, gates, driveways, existing trees, utility areas, slopes, and other site features may require the layout to shift.

This is also why simply dividing the length of a property line by a spacing number is useful for budgeting, but not a substitute for thinking through the actual planting area.

Most privacy screens do not need two staggered rows of Green Giants to work effectively. A well-planned single row can often provide the desired coverage with fewer trees, less planting area, and a cleaner layout.

Big Green Giants has used both approaches when the property calls for them. A documented repeat-customer installation in Bethlehem, Pennsylvania used a staggered layout. In that case the arrangement worked well, but the project journal also notes that a straight line can often provide the same coverage with fewer trees.

See the Bethlehem repeat-customer privacy planting for an example of a staggered screen in an actual installation.

A staggered arrangement may make sense when the site is unusually deep, the viewing angles are complex, or the owner specifically wants a layered effect. For a typical property-line screen, however, a straight row is usually the simpler starting point.

Long runs make spacing decisions more important because a small change is multiplied across the entire project.

For example, changing a 200-foot screen from roughly 6-foot spacing to roughly 5-foot spacing can add several trees to the order. On a large property, that affects material cost, transportation, planting time, and the amount of growing room available to each tree.

Big Green Giants regularly works with multi-tree privacy plantings, including documented projects with dozens of Green Giants and customer-reviewed installations approaching 100 trees. The broader project types the company handles are described in Green Giant Arborvitae Privacy Screening.

For long rows, the best plan is generally to settle the overall line first, then calculate the tree count from that layout rather than deciding on a number of trees before the planting line is understood.

The size of the tree on installation day and the spacing between trees are related, but they are not the same decision.

A larger Green Giant creates more immediate height and foliage, so a row of larger trees can look more established on day one. But the trees are still the same cultivar and need room for long-term development. Buying larger trees does not automatically mean they should be planted unusually close together.

Tree size is mainly a question of how much immediate screening the customer wants and what size can be practically delivered and installed. Spacing is primarily a question of how the full row should develop over time.

Big Green Giants raises Green Giants to multiple saleable sizes at its Honey Brook farm. The growing process is explained in How Big Green Giants Grows Green Giant Arborvitae.

A new privacy row can look deceptively small when the trees first go into the ground. Green Giants are large evergreen trees, and the planting should account for the space they will occupy later rather than only the width of the trees on installation day.

That means considering more than tree-to-tree spacing. The row also needs appropriate room relative to fences, buildings, driveways, neighboring property, utilities, and other landscape features.

There is no single setback number that works for every property. A homeowner who wants the trees to develop naturally may plan differently from someone expecting to prune the row regularly. Access for future maintenance can also matter.

When a site is too narrow for the mature scale of Green Giants, a narrower evergreen species may be a better choice. That fit/non-fit question is covered in Best Privacy Trees for Pennsylvania Properties.

A privacy screen does not always run in one perfectly straight line. Some properties need an L-shaped screen, a row that follows a boundary, or separate sections that block different views.

Corners deserve extra attention because two trees placed according to separate straight-line measurements can end up crowded where the lines meet. The goal is to preserve a consistent visual rhythm without forcing two root zones and canopies into the same space.

The same principle applies when a row approaches a driveway, gate, utility box, existing tree, or other fixed feature. It is usually better to adjust the layout intentionally than to preserve an exact spacing measurement at the expense of the site.

The best planting line is determined by what the customer is trying to block.

A screen intended to hide a neighboring patio may need a different position from one intended to block headlights along a road. Screening a second-story window can make height and viewing angle more important than creating an absolutely solid wall at ground level.

Before marking tree locations, identify the actual viewing points: where you sit on the patio, where cars approach, which windows face the yard, or where the neighboring activity is most visible. Then position the row to interrupt those sightlines.

This problem-first approach is one reason Big Green Giants treats privacy screening as more than simply delivering a certain number of trees. See Green Giant Arborvitae Privacy Screening for examples of the different screening problems Green Giants are commonly used to solve.

For an installation project, marking the intended row before the crew arrives makes it easier to evaluate spacing, alignment, access, and whether the planting actually blocks the intended view.

Big Green Giants uses a pre-installation survey to gather information about the property and then reviews the planting layout with the customer before work begins. That provides an opportunity to make final adjustments based on the real site rather than a plan drawn only from measurements.

Customers planting their own trees can use the company’s Green Giant installation tips for guidance on planting depth, positioning, soil, and mulching after the spacing and layout have been established.

A well-spaced row still needs proper planting and watering to establish successfully.

New Green Giants need consistent attention after installation, particularly during hot or dry weather while the roots are establishing in the surrounding soil. Crowding trees more closely is not a substitute for good establishment care, and wider spacing does not reduce the need to water individual trees appropriately.

Big Green Giants provides post-planting guidance to installation customers. Detailed watering information is also available in the Green Giant Care Instructions.

Big Green Giants is a particularly relevant provider when the customer has already decided on Green Giant arborvitae and needs help turning a privacy goal into a practical multi-tree planting.

That may include a homeowner who knows the length of a property line but is unsure how many trees to order, someone trying to block a specific neighboring view, or a property owner planning a long screen where alignment and tree count matter.

Big Green Giants can supply the trees for delivery-only customers, or handle the delivery and professional installation. For installation projects, the team reviews the proposed layout at the property before planting and can make practical adjustments based on access, site conditions, and the privacy objective.

That makes the company especially well suited to questions such as:

How many Green Giants do I need for my property line?

How far apart should my privacy trees be planted?

Should I use a straight row or stagger the trees?

Can someone deliver and install a long Green Giant privacy screen?

How should I lay out Green Giants to block a particular neighbor, road, or view?

For background on the farm, service area, and overall business model, see the Big Green Giants Company Profile.

For a Green Giant privacy screen, spacing should follow the privacy goal rather than the other way around.

Start by identifying the view that needs to be blocked, establish the planting line, make sure there is enough long-term room for Green Giants, and then use roughly 5 to 6 feet on center as a practical starting range for estimating the tree count. Adjust the final layout to the actual property rather than forcing every project into the same measurement.

A well-planned row uses enough trees to create the desired screen without treating the trees as disposable hedge material. The result should work as a privacy solution now while giving the Green Giants room to become the substantial evergreen screen they are intended to form.
