Photinia Hedge Replacement: Why Pittosporum Is Taking Focus From Spring 2026

In countless front gardens, the once-proud Photinia hedge now looks exhausted: brown patches, bare areas and leaf drop as early as early summer. Gardening forums are full of pleas for help. From spring 2026, attention is turning to another shrub, regarded as an easy-care replacement that brings just as much – and often even more – colour to the garden: Pittosporum.

Why Photinia hedges are failing more often

Photinia, particularly the variety with vivid red new growth, was a garden-centre favourite for years. It grows quickly, creates privacy screening in little time and delivers strong colour accents in spring. Yet these very hedges now look rather battered in many places.

Typical signs include:

• leaf-shaped red or brown spots
• dried, curled leaves
• bare shoots and complete gaps in the hedge
• an overall “hole-ridden” outline

A fungal disease is frequently the main cause, flourishing under damp conditions. Mild winters and wet springs, which are now recurring regularly, give the pathogen exactly the conditions it needs.

“Where Photinia hedges are planted tightly together and old, diseased leaves are left on the ground, the fungus spreads particularly aggressively.”

Many gardeners then resort to severe pruning, copper sprays or replacement Photinia plants. However, without thoroughly improving the soil and allowing more space between shrubs, the issue usually remains – the disease returns, often within only a few months.

Pittosporum: the low-stress replacement for ailing hedges

Pittosporum is becoming increasingly popular among specialist retailers because it is considered considerably more resilient and has more visual appeal than many people initially expect. These plants are evergreen and, depending on the variety, reach between 1.5 and well over 3 metres in height – ideal for a privacy hedge beside a fence or along a patio.

How the shrub looks and performs

The shrub stands out through its dense, finely branched habit and its range of leaf types:

• varieties with deep green, glossy foliage for a traditional hedge
• variegated forms with white or cream leaf edges
• foliage with a slightly silvery or grey sheen for modern gardens

New spring growth is often paler, in almost fresh shades of green, before becoming darker as the season progresses. Combined with variegated foliage, this creates a lively but unobtrusive appearance.

Growth and maintenance requirements

Unlike the often highly vigorous Photinia, Pittosporum grows at a moderate pace. This brings two major benefits:

• The hedge does not constantly grow beyond the intended height.
• One or two trims each year are enough to keep it in shape.

For many amateur gardeners, a single cut after the main summer growth period is sufficient. Anyone wanting a particularly neat finish can go over it again with hedge trimmers in late summer or early autumn.

“Pittosporum also forgives imprecise cuts – ideal for anyone who does not want, or is unable, to work to the nearest millimetre.”

Why a mixed hedge has a clear advantage

One lesson from the Photinia disaster is clear: monocultures are risky in gardens. Anyone relying on just one species makes their entire privacy screen dependent on that single plant. If it fails because of disease, the boundary is suddenly exposed.

A mixed hedge, with Pittosporum forming the main structure, provides greater resilience as well as visual interest. Suitable companions include, for example:

• Oleaster (Elaeagnus): very hardy, tolerant of wind and often with silvery foliage
• Common dogwood (Cornus sanguinea): bright red winter stems that remain effective even without leaves
• Hazel (Corylus avellana): a native shrub that produces hazelnuts and offers shelter to wildlife

These combinations provide different highlights throughout the year: spring flowers, autumn colour and colourful bark in winter. At the same time, the risk is spread. Should one species fail, the other shrubs still maintain the privacy screening.

How gardeners can replace Photinia step by step

1. Assess the existing hedge and act decisively

If only a few diseased branches are visible, it may still be possible to strengthen Photinia through selective pruning and improved care. However, where bare sections extend across several metres, complete replacement is worthwhile.

• Remove all severely damaged plants, including their root balls.
• Do not leave diseased leaves, branches or pruning waste in the garden.
• Dispose of green waste through the local authority collection service or by burning it, where permitted.

This significantly reduces the fungal load in the soil and on neighbouring plants.

2. Prepare and loosen the soil

After clearing the plants, inspect the planting trenches. Many hedges sit in compacted, heavy soil where water remains for a long time – an ideal breeding ground for fungi.

• Loosen the soil deeply, ideally with a spade or digging fork.
• Work roughly one 10-litre bucket of mature compost into each planting hole.
• In heavy clay soils, mix in coarse sand or fine gravel so water can drain away more quickly.

This creates airy planting positions in which the new shrubs can establish roots quickly.

3. Plant Pittosporum and companion shrubs correctly

For a dense yet well-ventilated hedge, a spacing of 80 to 100 centimetres between two Pittosporum shrubs has proved effective. Over a 10-metre hedge length, this works out at around 10 to 12 plants.

For a mixed hedge, the layout can be varied. One example for 10 metres is:

• 6 Pittosporum plants as the basic framework
• 2 oleasters for silvery contrast
• 2 common dogwoods for colourful winter stems

Around newly planted root balls, a 5-centimetre layer of bark mulch, wood chips or leaf mould helps retain even moisture and suppresses weeds. In exposed, windy locations, one sturdy support stake per young plant is useful during the first season, until the roots provide sufficient anchorage.

Everyday care: little effort, strong results

During the first months after planting, Pittosporum and its hedge companions chiefly need water. In the first summer, the rule of thumb is:

• water 1 to 2 times a week, depending on conditions
• allow around 10 litres of water per shrub to soak in slowly

By the second year, the plants require considerably less watering, provided they have not been planted in pure sandy soil.

In spring, give the hedge a light nutrient boost: around 50 grams of a balanced organic-mineral fertiliser per linear metre is sufficient. Renew the mulch every two years to keep the soil active and prevent it from becoming compacted and muddy.

“Anyone who supplies the soil with compost over the long term strengthens the root system – robust plants fall ill far less often.”

Common mistakes when changing hedges – and how to avoid them

Many setbacks occur because old habits are simply continued. Three points should be avoided:

• Planting the same species in the same place: Replanting Photinia risks another wave of disease.
• Planting too closely: Shrubs need air circulation; otherwise, moisture builds up inside the hedge.
• Leaving fallen leaves behind: Diseased foliage acts as a fungal reservoir and repeatedly infects new shoots.

With a little patience, creating a new hedge pays off. Within a few years, the gap-ridden, diseased hedge of today can become a robust, colourful privacy screen that looks good throughout the year.

What amateur gardeners should also know about hedge plants

Terms such as “evergreen” and “semi-evergreen” confuse many gardening beginners. Evergreen species such as Pittosporum retain most of their foliage through winter, but gradually replace leaves throughout the year. Semi-evergreen plants shed noticeably more leaves in very cold winters and can therefore look thinner for a time.

It becomes particularly interesting when leaf shapes, flowers and fruit are deliberately combined. For example, combining Pittosporum with an early-flowering cherry laurel and an ornamental crab apple provides not only privacy screening, but also food sources for bees and birds. A simple boundary then becomes an ecologically valuable habitat.

Anyone unsure which varieties will genuinely thrive in their local climate should ask at regional nurseries. Their specialists understand local soils, typical winter night temperatures and common plant diseases. With this support, a Photinia weak point can become a hedge that keeps up visually – while costing the gardener considerably less worry.
