Planting in fall
It is the best season to plant. Photinia are best planted in fall to promote root development.
In fall, photinia won’t have any red leaves: they’re all green by this time!
The best time is November; however, you can plant as early as September and as late as December. Just make sure not to plant when it freezes.
Planting in spring and summer
Photinia can be planted in spring and even in summer if purchased in pots.
In this case, water often: the shrubs’ needs are higher, and it doesn’t yet have many roots.
- Don’t plant during heat waves.
- Mulch the base of your Photinia.
- This keeps soil moist for much longer.
- Follow our advice on planting shrubs
- For a 6-foot hedge (1.8m), plant each photinia 3 feet (1m) from the next.
- Fast growing photinia is ideal for all types of hedge, even topiary.
It is possible to propagate Photinia from cuttings in summer.
- Collect stems that are 4 to 6 inches (10 to 15 cm) long.
- Remove lower pairs of leaves. Keep only the topmost one or two pairs.
- It is possible to dip the cuttings in powdered rooting agents.
- Plant them upright in special cutting soil mix.
- Put the Photinia cuttings near light, but not in direct sunlight.
- Keep substrate a little moist.
- Make sure the cuttings won’t freeze in winter.
- Transplant to a slightly larger pot in the following spring.
The most famous variety is Photinia ‘Red Robin’. Other varieties are just as beautiful, but harder to find: ‘Red Tip’, ‘Little Red Robin’, ‘Pink Crispy’, ‘Pink Marble’ (last two have variegated leaves)…
Pruning and care for Photinia
Photinia are easy shrubs to care for, especially when well settled in.
Pruning and trimming

Photinia can be shaped as you wish: cones, spheres, columns and other topiary…
- First, thin older branches to trigger growth of new shoots. Also clear the center so that light can reach it.
- The more you prune, the faster it grows.
- Frequent and drastic pruning renews growth and makes fresh red leaves appear.

- In pots, remember to topdress with ripe compost every year in spring and fall.
- Instead of topdressing, give your shrub a dose of weedy tea every month during the growing phase.
Diseases, pests, and problems with Photinia
Although Photinia is very resilient and won’t often get diseased, sometimes the following may occur.
Photinia not blooming
If you have a photinia not bearing flowers, there are usually two reasons. Sometimes both are at play.
- Pruning was performed at the end of winter, before the blooming – in this case, flower buds were cut off. Try to prune and trim your photinia after the blooming in spring. If you need to prune a second time to keep the shrub small and tidy, do it in fall before winter .
- Exposure and lack of sunlight – a photinia shrub that is mostly growing in shade won’t bear many flowers, sometimes to the point of not bearing any at all. If under the shade of a taller tree, try thinning out branches of the tall tree. That way, more light reaches the photinia shrub.

This red-leaved shrub is an ornamental shrub, in beds and in hedges. However, you can also plant it as a standalone.
Abundant leaves quickly make the shrub opaque, which makes it one of the most commonly planted evergreen hedge shrubs.
