How to Create Privacy in a Small Garden Without Losing Light
Most people's first instinct for garden privacy is a fence. The second is a tall hedge. Both can work, but both have the same problem in a small garden: they block light as thoroughly as they block sightlines. A two-metre featheredge fence or a dense Leyland hedge turns a small garden into a box — private, yes, but dark, enclosed, and airless.
The better approach is to screen selectively rather than completely. Identify the specific sightlines that need blocking — the neighbour's upstairs window, the overlooking terrace, the gap at the end of the fence — and address those points precisely, rather than building a barrier around the entire garden. This is where narrow, vertical plants become genuinely useful.
The short version: Screen the specific sightlines that need blocking rather than building a barrier around the whole garden. Narrow columnar evergreens reach the same screening height as a traditional hedge at roughly half the width, casting far less shadow. Good options: Italian cypress for sun, clipped yew for shade, photinia or laurel standards for an elevated screen, or pleached trees for upstairs windows. Avoid leylandii, bamboo, and willow in small spaces.
The Width vs Height Trade-Off
A traditional garden hedge — privet, hornbeam, beech — is often 60–90cm wide at maturity. In a small garden of 4–6 metres width, a hedge that wide along one or two boundaries consumes a significant proportion of the usable space. It also casts a wide shadow band throughout the day, reducing the growing conditions for anything nearby.
Narrow columnar plants — specimens that grow primarily upward with minimal sideways spread — can reach the same screening height at 25–40cm of width. The shadow they cast is a narrow strip rather than a wide band, which means plants nearby receive far more light throughout the day. This is the core trade-off: width versus height, and in a small garden, narrow always wins.
Narrow Columnar Plants That Screen Without Stealing Light
Cupressus sempervirens 'Stricta' (Italian cypress — dark, dense aromatic column). The most architecturally striking narrow screening plant available. Reaches 4–6m at maturity at under 60cm wide. Needs full sun and good drainage. Not suitable for heavy clay or north-facing positions. Perfect for a contemporary garden that needs a Mediterranean accent at a sightline point.
Taxus baccata column (yew — dark flat needles, very dense and clippable). Clipped into a column or narrow obelisk, yew can be maintained at 40–50cm wide indefinitely. It tolerates deep shade, making it the only viable narrow evergreen screen for a genuinely dark small garden. Grows slowly but holds its shape for years. Fully hardy.
Photinia 'Red Robin' standard (glossy leaves with vivid red new growth). Trained as a lollipop or narrow standard, photinia provides an elevated screen at eye level — blocking the sightline without creating a ground-level shadow. The red new growth in spring is a genuine ornamental bonus.
Prunus lusitanica column (small, glossy leaves on red-tinged stems — clipped to a narrow upright form). Hardy, shade-tolerant, and manageable. A column of clipped Portuguese laurel at 1.8–2m height provides a solid screen in a width of 40–50cm. Works against a fence or wall where a hedge would be too wide.
Pleached Trees as Elevated Screens
Where the privacy problem is specifically an elevated one — an upstairs window, a first-floor terrace — a pleached screen is often the most elegant solution. Pleached trees are trained to produce a flat, hedge-like canopy at a specified height on clear stems. Below the canopy, the stems take minimal space and cast minimal shadow. Above, the screen blocks elevated sightlines that a ground-level hedge never reaches.
Hornbeam (Carpinus betulus) and field maple (Acer campestre) are the most common pleaching subjects — both deciduous, so they lose their screen in winter but provide dappled rather than full shade in summer. For a year-round evergreen pleached screen, Ilex aquifolium (holly) or Quercus ilex (holm oak) are used, though both are slower to establish and more expensive to buy at suitable sizes.
What Doesn't Work in Small Gardens
Some popular privacy choices are genuinely poor decisions in small gardens, and it's worth being direct about which ones:
Leylandii — fast-growing, yes, but completely unsuitable for small spaces. It grows at 90cm per year and needs trimming three times annually to be kept manageable. Untrimmed, it becomes a neighbourhood dispute within five years. Even well-maintained leylandii is too wide and too aggressive for a garden measured in single-digit metres.
Bamboo — running bamboo varieties spread through underground rhizomes that can cross boundaries, emerge through paving, and are extraordinarily difficult to remove once established. Clumping bamboos are better-behaved but still large at maturity. In a small garden with limited soil area, bamboo is a risk not worth taking.
Fast-growing willows — thirsty, wide, and structurally demanding. Willow screens need very large root runs, consume significant moisture (affecting neighbouring plants and potentially foundations), and grow quickly enough that maintenance becomes a significant annual commitment.

Frequently Asked Questions
How do I get privacy in a small garden?
Identify the specific sightlines that need blocking and address them with narrow, tall planting at those exact points rather than trying to create a solid barrier around the entire garden. One or two columnar evergreens or trained standards positioned at the sightline source — a neighbour's window, a gate gap — provide effective screening with far less impact on light and space than a full boundary hedge.
What is the best screening plant for a small garden?
For a sunny position: Cupressus sempervirens 'Stricta' — nothing else gives the same height at the same narrow width. For a shaded or partially shaded position: Taxus baccata clipped into a column is the reliable choice. For an elevated screen (blocking upper-storey sightlines): a pleached hornbeam or standard trained at height gives privacy above fence level without blocking light at ground level.
How do you block neighbours without a fence?
Narrow columnar evergreens positioned at the sightline point are the most effective living screen. Placed in containers, they can be positioned precisely — including on paved surfaces with no soil — and repositioned if needed. A pair of 180cm columnar evergreens in large containers can be moved to exactly where the privacy is needed, without any permanent installation or ground preparation.
