No more bare hedges: This hardy privacy shrub outperforms photinia.

Anyone wanting to shield their garden from prying eyes often turns to fast-growing hedge plants. First thuja was everywhere; then the red-flushing Photinia swept through new-build estates. It’s now becoming clear that this fashion comes at a cost. Fungal diseases are stripping out entire lines of planting. Landscape gardeners are therefore increasingly recommending a different evergreen shrub-already viewed in France as a new benchmark for dense, low-maintenance greenery-and one with huge potential in the UK too.

Why Photinia fails in so many gardens

When a red hedge suddenly develops brown spots

For years, Photinia ‘Red Robin’ was seen as the ideal answer: striking red new growth in spring, rapid growth, and a tall screen in no time. In real gardens, however, the picture has shifted. A leaf fungus that spreads quickly in damp springs can severely weaken the plants. Leaves develop brown spotting and blotches, then dry out and eventually drop.

The result is that, instead of a thick, private wall of foliage, you’re left with a gappy framework of bare twigs. In terraced housing areas and on small plots, that’s particularly frustrating because the privacy you planted for simply disappears. If you persist with Photinia, you often end up constantly removing diseased leaves, spraying, and cutting back-only to see limited improvement.

"In many gardens, Photinia hedges lose so much foliage that the screening is practically no longer there."

Homeowner frustration: high costs, little payoff

Many owners invested in these shrubs precisely because they grow quickly and look impressive. Now they are faced with sparse hedges and rising ongoing costs. Fungicides, repeated cutting back, and disposing of infected leaves all take time and money. Even then, the fungus frequently returns-especially in areas with mild winters and wet springs.

Amateur gardeners report having to remove entire shrubs. Some replace the hedge in sections; others give up altogether and look for an alternative that won’t turn into an annual problem. That is where a shrub comes into the frame that, until recently, was more of an insider tip.

A hedge monoculture is a risk-and it tends to backfire

Photinia’s decline echoes what happened to pure thuja hedges. Once a single species dominates front gardens, one specialised pest or pathogen can hit whole neighbourhoods. This kind of “hedge monoculture” is extremely vulnerable to emerging diseases, which can spread more easily with climate change and mild winters.

Garden centres are already adjusting. In many stores, Photinia is being stocked less, while other evergreen shrubs are taking up more shelf space. One glossy-leaved, varied, generally healthy shrub is increasingly in the spotlight: Pittosporum.

Pittosporum: the underestimated star for dense, modern hedges

Pittosporum hedges: evergreen, colourful and holds its shape

Pittosporum-often sold simply as Pittosporum-offers exactly the qualities that suit densely built-up residential areas: it stays green all year, grows in a compact habit, and responds well to trimming. Depending on the variety, the leaves can show an eye-catching mix of deep green, lighter green and creamy variegation. Some look almost like miniature designer plants.

Annual growth is typically around 20 to 30 centimetres. That means you can establish an effective privacy screen fairly quickly, without needing to hack the hedge back hard every year. With regular shaping using hedge shears, you can keep a uniform, dense wall that doesn’t turn see-through in winter.

• Height: depending on the variety, typically 1.5 to 3 metres
  
• Width: compact; easy to shape through pruning
  
• Leaf colour: from deep green to yellow- or white-variegated
  
• Position: sun to partial shade; a sheltered spot is ideal
  
• Maintenance: low; one shaping or maintenance cut per year is usually enough
  

Visually, Pittosporum reads as more contemporary than classic conifer hedging. The glossy leaves catch and reflect light, while variegated forms add structure to the green. If you want to avoid the sometimes slightly “stuffy” feel of thuja, this is a more up-to-date alternative.

A calmer gardening life thanks to strong disease resistance

A key benefit is its robustness against leaf fungi. While Photinia can deteriorate quickly in damp spells, Pittosporum generally remains healthy. It doesn’t require routine fungicide treatments, which is kinder both to the environment and to your budget.

"Pittosporum hedges remain stable and dense in many locations-without harsh chemicals and without constant stress for amateur gardeners."

In practice, care comes down to three main tasks: one well-timed cut each year, occasional watering during dry periods, and modest feeding in spring. If you improve the planting soil with compost and avoid waterlogging, you set the foundation for a long-lived hedge.

How to use Pittosporum effectively in garden design

A single-species hedge or a mixed planting-which works better?

Pittosporum works both as a uniform hedge and as part of a mixed planting scheme. Professionals increasingly recommend so-called mixed hedges, combining several shrubs that complement each other in height, leaf shape and flowering period. The advantage is that diseases tend to spread less rapidly, and the hedge looks more varied.

Popular companions for Pittosporum include, for example:

• Elaeagnus (oleaster): very tough, with silvery foliage; ideal for windy sites
  
• Hazel: brings catkins in late winter and nuts for wildlife
  
• Cornus (dogwood species): striking red or yellow winter stems; an excellent colour accent
  
• Privet: a classic, clip-tolerant hedge shrub with high tolerance overall
  

Mixed hedges don’t just look more alive. They also offer birds, insects and other garden wildlife more food sources and hiding places than a uniform row of identical plants.

Site, soil and pruning: the key practical tips

To help Pittosporum deliver its full potential as a dense privacy screen, a few straightforward rules make a real difference:

• Keep to the right spacing: depending on the variety, allow around 60 to 80 centimetres between plants so they can branch well.
  
• Prepare the soil properly: loosen compacted ground, improve with compost, and prevent waterlogging.
  
• Provide shelter from wind: especially variegated varieties reward a protected position with fuller growth.
  
• Water while establishing: in the first two years, water regularly-particularly during heatwaves.
  
• Shape rather than cut back hard: a light trim after the main flush of growth is usually enough; hard renovation cuts only when necessary.
  

Follow these points and you can build a hedge that provides reliable screening for years-without becoming a constant maintenance project.

What garden owners can do now

Save an old Photinia hedge-or replace it?

If you already have a weakened Photinia hedge, it’s worth taking a realistic look at its condition. Individual plants that still have vigour can be supported with targeted measures: remove infected shoots, open the hedge slightly to improve airflow, improve the soil and adjust watering. Where the fungus hits hard year after year, replacement is often the less stressful route.

A full change doesn’t have to happen all at once. Many gardeners work section by section: remove part of the old hedge and replant gradually-perhaps with Pittosporum combined with other species. That way, you retain some screening while the new structure starts to establish.

Assessing Pittosporum’s risks and limits realistically

Even though Pittosporum is robust, it won’t suit every garden. In very exposed, frost-prone areas, more sensitive varieties can suffer dieback. If you live in a colder region, it’s wiser to choose more cold-tolerant types or plan some wind protection. In very dry, hot courtyards, the shrub needs more water at first until its roots reach deeper moisture.

Even so, the overall picture remains far more positive than with Photinia: by comparison, the plant is considered low in disease issues, easy to shape, and visually varied. That matches what many homeowners want-a green screen that doesn’t bring a fresh set of problems every year.

More variety for stronger, more vibrant gardens

The move away from Photinia and towards Pittosporum shows how strongly gardening fashions can shape entire streets-and how risky it can be to rely on a single species. If you’re planting now, a mix of Pittosporum plus other resilient shrubs is a much safer approach. The hedge becomes more varied, more resistant, and a habitat for many animals.

For many property owners, that creates a real opportunity: rather than choosing the next short-lived trend shrub, it can be worth switching to long-term, diverse planting. Pittosporum can play a central role in that-not as a lone star, but as a dependable building block in a garden that smartly balances privacy, appearance and nature-friendly choices.
