Pittosporum replaces Photinia ‘Red Robin’ as the new privacy hedge favourite

Many garden owners are frustrated by Photinia hedges full of holes – while another remarkably undemanding shrub is quietly taking centre stage.

Anyone who chose the fashionable Photinia ‘Red Robin’ shrub in recent years is now often faced with a disappointing sight: bare branches, brown spots and an ongoing need for sprays. As entire neighbourhoods complain about the declining appearance of their hedges, a previously underestimated alternative is moving into focus: Pittosporum. But what makes it so resilient, and is changing over worthwhile in Central European gardens?

Why Photinia fails in so many gardens

Spotted foliage and bare hedges: the fungal issue

The former star of front-garden hedges has a serious health weakness. A particular leaf fungus attacks Photinia aggressively. Small brown marks first appear on the leaves, then spread quickly. The foliage can no longer function properly, dries out and eventually drops.

“What began as a dense privacy screen often ends as a sparse forest of stems – with privacy lost completely.”

Mild winters and damp springs are especially problematic. These conditions are ideal for the fungus, allowing it to multiply rapidly and infect entire rows of plants. In many new-build developments, it is now possible to see kilometres of hedges deteriorating at the same time.

High maintenance, limited results

Many homeowners attempt to tackle the problem by:

• spraying fungicides several times each year
• pruning frequently to remove diseased shoots
• continually collecting and disposing of affected leaves

Even with all this effort, the outcome is usually disappointing. Costs rise, patience wears thin, and the fungus generally returns the following year – often more severely than before. Amateur gardeners in particular quickly become discouraged and begin looking for a more sustainable option.

The fashionable hedge has reached its limit

This situation strongly recalls the decline of Thuja hedges a few years ago. In that case too, one plant species had been planted extensively everywhere. Once disease and pests take hold, such monocultures have little chance of coping.

Garden professionals have been noticing a clear shift in attitudes for some time. Demand for Photinia is falling, while many nurseries are reducing their range. More robust species are taking its place – and this is where Pittosporum’s quiet rise begins.

Pittosporum: the new favourite for dense, contemporary privacy hedges

Evergreen, colourful and easy to shape

Originally from warmer regions, Pittosporum has proved surprisingly adaptable in many Central European locations. The shrub offers several qualities that are essential for a hedge:

• Evergreen foliage: year-round screening, including in winter
• Dense branching: creates an effective visual barrier after only a few years
• Moderate growth: usually grows by 20–30 cm annually, making it easy to manage
• Attractive leaves: depending on the variety, foliage may be green, grey-green or decoratively variegated

Many varieties have slightly glossy, almost leathery leaves. As well as looking refined, these provide a calm, graphic backdrop for perennials or ornamental grasses in a border. This appearance is a particular advantage for the front gardens of contemporary homes.

Far lower disease pressure

Pittosporum’s greatest strength is its resilience against the common leaf fungi that trouble Photinia. In practical terms, this means:

• a much lower risk of severe leaf loss
• little need for chemical plant protection
• hedges that remain evenly dense for many years

“Pittosporum is not considered invulnerable, but it is a far more dependable choice for anyone wanting a hedge without constant stress.”

The environmental aspect is now also important to many garden owners. Anyone wishing to avoid sprays needs plants that are naturally more robust. On this point, Photinia is clearly at a disadvantage.

Low-maintenance rather than demanding

Pittosporum is not entirely maintenance-free, but the work involved remains manageable:

• Pruning: one light trim each year is normally enough
• Watering: water regularly during the first years after planting, then only during extended dry periods
• Feeding: a small amount of organic fertiliser or compost in spring is sufficient

Many varieties tolerate both sunshine and bright partial shade. Growth can stall in very heavy, waterlogged soil; a drainage layer or planting on slightly raised strips can help in these conditions.

How to use Pittosporum as a privacy screen in your garden

The right planting density for an opaque hedge

The required spacing depends on the variety and the intended height. As a general guide:

Planned hedge height	Recommended planting distance
up to 1.20 m	50–60 cm
1.50–1.80 m	60–80 cm
over 2.00 m	70–90 cm

For a privacy screen that closes in particularly quickly, plant at the narrower end of the range. Those with more time who want very robust individual shrubs over the long term can allow wider gaps.

Suitable varieties for Central European gardens

A range of species and varieties is available from retailers. Common options include:

• Pittosporum tenuifolium: an upright, slender grower that is highly popular for hedging
• Variegated varieties: with creamy white or yellowish leaf margins, ideal for lighter accents
• Compact dwarf forms: suited to low edging or container planting

Winter protection is an important consideration in harsher locations. Many varieties cope with light frost, but fleece, a layer of leaves around the root area, or a somewhat more sheltered site will help during severe cold spells.

Why mixed hedges are the better long-term choice

More species, less risk

Many specialists now advise against hedges made up of just one plant species. This also applies to Pittosporum, however robust it may be. Mixed hedges reduce the risk that a single pest or fungus will ruin the entire privacy-screening project.

Successful combinations include:

• Elaeagnus (oleaster) for silvery shimmering foliage
• hazel shrubs for naturalistic garden areas
• Cornus (dogwood) for colourful stems in winter

“A mixed hedge not only shields a garden from prying eyes, but also creates habitat for birds, insects and small mammals.”

Shrubs that flower at different times supply nectar over many months. Berry-bearing species provide food for birds in autumn and winter. In this way, a simple screen becomes a small, stable ecosystem.

Greater design flexibility for front gardens and patios

Combining Pittosporum with other species also brings visual benefits. Pale, variegated foliage can make darker conifers appear fresher. Planted beside grasses, it creates a modern, almost Mediterranean atmosphere – without making the garden look as though it came from a holiday brochure.

Conveniently, many Pittosporum varieties also grow well in large containers on balconies or patios. This makes it possible to create a consistent style around the home, from the front garden to the roof terrace.

What garden owners should consider before switching

Before removing a weakened Photinia hedge entirely, it is worth assessing the situation closely. If only individual plants are badly affected, partial replacement may make sense. However, anyone who has been battling the issue for years and sees the same damage repeatedly will often be better served by a complete restart.

Pittosporum offers better disease resistance, lower maintenance needs and appealing foliage. The one critical consideration is winter hardiness within the local microclimate. In exposed, windy locations or at higher elevations, it is sensible to trial individual plants before redesigning an entire boundary.

Choosing a mixed hedge from the outset spreads the risk and increases the garden’s ecological value. Pittosporum can form the central evergreen component – without the weaknesses that many gardeners now associate with Photinia.
