How far apart to plant Blue Point junipers depends mostly on whether you want one solid wall or separate, shapely trees. For a privacy screen, plant them about 5 to 6 feet apart, measured trunk to trunk. For trees meant to stand alone, give them at least 8 feet. The gap between the two choices is only a few feet, but Blue Point grows into a fuller, broader pyramid than its narrow nursery-pot look suggests, so a spacing that looks generous on planting day can be crowded a decade later.1Garden Goods Direct.

Spacing for a Blue Point Juniper Privacy Screen
For a living wall or privacy screen, space Blue Point junipers about 5 to 6 feet apart.2Southern Living Plants. Southern Living® Junipers – Southern Living Plants That distance is measured on center, meaning from the trunk of one tree to the trunk of the next, not between the outer branches. At that spacing the trees start as separate cones and gradually grow together into a continuous screen.3Plant Addicts. Blue Point Juniper Some growers suggest as little as 4 feet for faster screening,4The Landscape Library. Blue Point Juniper: How to Grow, Care, and Design With Juniperus chinensis ‘Blue Point’ but that means more crowding later.
Closer isn’t simply better. Blue Point keeps its full pyramid shape best when it isn’t crowded against its neighbors, and the University of Florida notes it prefers not to be crowded at the base.5The Landscape Library. Blue Point Juniper: How to Grow, Care, and Design With Juniperus chinensis ‘Blue Point’6University of Florida IFAS Extension. Blue Point Juniper Trees jammed tightly together can lose lower foliage where their branches shade and rub each other.
Before digging, run a string line along where the row will go and mark each trunk spot with a stake or flag. Measure each gap from stake center to stake center, the same way the trunks will be measured later. To work out how many trees you need, divide the row length by your spacing and add one for the end.
If a utility box, downspout, or old stump sits where a stake lands, shift the whole row’s spacing slightly so the trees stay evenly spaced instead of crowding one side of the obstacle. Call your local utility locator service before digging a long row, since buried lines often run along fences and property edges.
A staggered zigzag of two rows can close sightlines faster than one straight row. In that layout, keep each tree about 5 to 6 feet from every neighbor, diagonals included. A double row needs much more depth, so it suits a wide side yard rather than a narrow strip.
The tempting mistake is planting small trees 2 or 3 feet apart for instant privacy. Within several years they push into each other, and the problem is hard to correct without removing some.
Spacing for Single Accent or Specimen Trees
Give Blue Points that are meant to stand alone at least 8 feet of space.7Plant Addicts. Blue Point Juniper At 8 feet each tree can show its whole silhouette without touching its neighbor.8University of Florida IFAS Extension. Blue Point Juniper (Juniperus chinensis ‘Blue Point’)9Southern Living Plants. Southern Living® Junipers – Southern Living Plants That is also the spacing to use for a broad screen where you want each pyramid to stay distinct.10Plant Addicts. Blue Point Juniper A spacing in between, like 7 feet, gives you neither a clean wall nor clearly separate trees for years.
For a pair flanking a doorway, gate, or driveway, give both trees equal room so neither leans or thins on one side. Measure 8 feet or more between the two trunks, centered on the entry. Leave room on the walkway side too, so branches won’t brush people walking past.
In a mixed bed, shorter shrubs and perennials planted next to a Blue Point will be shaded and crowded as it widens. Leave about half the juniper’s mature width, 3 to 4 feet, clear around its trunk. Fill that space with mulch or low temporary plants while the juniper grows.
An 8-foot gap looks wide when the trees are small, but bare ground between young junipers is expected. Mulch keeps weeds down and helps the soil hold moisture in the meantime.
How Big Blue Point Junipers Get and How Fast
The University of Florida lists Blue Point’s mature size as about 12 feet tall and 8 feet wide.11University of Florida IFAS Extension. Blue Point Juniper (Juniperus chinensis ‘Blue Point’) Nursery listings range from 10 to 15 feet tall and 4 to 10 feet wide,12PlantingTree. Blue Point Juniper | Blue Point Juniper for Sale and one nursery lists a narrower 4 to 6 feet wide.13Michigan Timber Shack Tree Farm & Nursery. Blue Point Juniper Planning for about 8 feet of width is the safe assumption for most yards, because Blue Point isn’t a skinny column but a broad pyramid that thickens as it matures.14Garden Goods Direct. Blue Point Juniper
The listings disagree because growers measure under different conditions, such as climate, soil, sun, and pruning. A narrow listing may describe a tree pruned or grown in ideal conditions, so don’t plan on it unless you will keep the tree trimmed.
Two 8-foot-wide trees planted 8 feet apart will just meet at maturity. At 5 to 6 feet apart, the same trees overlap, and that overlap creates a solid screen. Plant farther apart than the mature width and you leave permanent gaps.
Expect growth of about 6 to 12 inches a year.15PlantingTree. Blue Point Juniper | Blue Point Juniper for Sale In good conditions one nursery reports 12 to 18 inches a year.16Michigan Timber Shack Tree Farm & Nursery. Blue Point Juniper Young trees spaced 5 to 6 feet apart typically take several years to touch and form a solid screen.
In the first year or two after planting, expect separate cones with clear gaps. Over the next few years the branches begin to touch, and the bottom gaps close first.
Full sun, steady watering in the first year or two, and well-drained soil push growth toward the faster end of the range. Poor drainage, heavy shade, or compacted soil keep it at or below the slower end.
Why Spacing Affects Juniper Health
Junipers stay healthiest in full sun with good air circulation.17Home & Garden Information Center. Juniper Diseases and Insect Pests in South Carolina That’s why extension services advise spacing plants to improve airflow.18Home & Garden Information Center. Juniper Diseases and Insect Pests in South Carolina Good circulation helps prevent twig blight, a disease that browns juniper tips.19Pacific Northwest Pest Management Handbooks. Juniper (Juniperus spp.)-Twig Blight Foliage in the middle of a tight row gets little wind, so rain and morning dew take longer to dry, and wet foliage lets fungal diseases get started. A tightly crammed row stays damp inside longer and is more likely to show browning branches.
Heavily shaded trees grow sparse foliage.20University of Florida IFAS Extension. Blue Point Juniper (Juniperus chinensis ‘Blue Point’) When trees shade each other at the base, the lower branches thin out. Junipers also need well-drained soil, so avoid running a row through a low, soggy spot.21University of Florida IFAS Extension. Blue Point Juniper (Juniperus chinensis ‘Blue Point’)
Twig blight shows up as branch tips that turn brown or gray while older growth deeper inside stays green. It is often worse after long wet spells, because moisture sitting on dense foliage helps the fungus spread. Several things can brown a juniper, including drought and winter burn, so look at the pattern: blight tends to affect scattered tips rather than the whole tree at once.
Bare inner and lower branches where trees touch usually mean light isn’t reaching them. Removing every other tree in an overcrowded young row can save the rest.
Once a screen closes, water at the base rather than spraying the foliage so branches dry quickly. Keep mulch a few inches away from the trunks, and prune out any browned branches promptly in dry weather.
How Far to Plant From Houses, Fences, and Walkways
With a mature width around 8 feet, branches reach about 4 feet out from the trunk in every direction. Planting at least 4 to 5 feet from a fence or wall keeps branches from pressing against it. Roots matter too: tree roots spread mostly sideways in the top 12 inches of soil and reach beyond the branch tips.22Journal of Environmental Horticulture. Tree Root Growth and Development. I. Form, Spread, Depth and Periodicity Keep trees a few feet back from patios, walkways, and irrigation lines so digging and roots don’t conflict.
Measure the setback from the trunk, not from the edge of the nursery pot or the planting hole. If the space is tighter than 4 to 5 feet, accept that the branches will touch the fence and plan on pruning.
Behind a fence-line screen you will need to reach the back side to prune, check for blight, and repair the fence. A 4 to 5 foot setback leaves a narrow path once the trees fill out. Planting hard against a fence traps the back branches in shade, and they thin out.
Trunks sitting right on a property line send branches across it. Check local rules or neighbor agreements before planting a boundary screen. Setting the row back keeps all of the mature tree on your side.
Under eaves, rain and sun are blocked, which leaves the house side of the tree dry and thin. A 12-foot tree can also eventually block a window, so check its height against what’s above. Junipers are not known for heavy, damaging roots, but keep them away from septic fields, drain lines, and sprinkler lines.
In wildfire-prone regions, extension services list juniper as a highly flammable plant to keep out of the defensible space around a home.23UA Cooperative Extension. Smart winter yardwork: Create a wildfire defensible space around your home If you live where wildfire is a risk, plant Blue Points well away from the house and use them for screening at the property edge instead.
How Blue Point Compares With Other Screening Junipers
The narrower Spartan juniper can be planted 3 to 4 feet apart for a hedge and 5 feet or more as a specimen.24Southern Living Plants. Southern Living® Junipers – Southern Living Plants Blue Point needs about 5 to 6 feet for a screen and 8 for specimens.25Southern Living Plants. Southern Living® Junipers – Southern Living Plants Don’t reuse Spartan spacing for Blue Point, or the broader pyramids will crowd.
A plant with a slimmer mature width needs less room on each side, so its branches don’t overlap until the trunks are very close. Spartan is more upright and narrow, so the 3 to 4 foot hedge spacing suits it. Blue Point’s wide pyramid would fill that same gap and overlap heavily within a few years.
At 3 to 4 feet, trunks are only about half the mature width apart, so the trees compete for light and air. The result is the crowding problem described earlier, with thin lower branches and more risk of blight. The fix later is removing trees, which is harder than spacing correctly at the start.
Check your plant tag before you dig. Nursery tags list the cultivar name, so confirm it says ‘Blue Point’. Different juniper cultivars look similar in small pots but grow very differently. If the tag lists a narrower width than general advice, remember that narrow listings often assume pruning, so plan for about 8 feet unless you will keep the tree trimmed.
