Expert tips
The key tip
Photinia needs at least 6 hours of direct sunlight daily to keep its vibrant red foliage. Prune it in late winter to control height and encourage branching density.
The common mistake
Placing it in partial shade or pruning too lightly results in a leggy shrub with pale green, less ornamental foliage.
The pro's trick
Pinch back young shoots in May for natural branching and to maintain compact, dense foliage.
Care
Sunlight
Plant your photinia in full sun to optimise the purple colouring of young foliage. At least 6 hours of direct sunlight daily is necessary. Partial shade is tolerated but will reduce the characteristic red hue.
Watering
Water regularly during the first year to establish a strong root system. In the ground, moderate water needs are usually met by rainfall. In pots, check that the substrate doesn't dry out completely between waterings, especially during hot periods.
Pruning
Prune after flowering (June) to shape the plant and encourage dense branching. Remove dead or poorly oriented branches. Regular pruning promotes the production of young red leaves, which are highly decorative.
Soil
Prepare well-drained soil enriched with organic matter. Photinia prefers slightly acidic to neutral soil. Avoid waterlogging, which promotes fungal diseases. Light mulching helps retain summer moisture.
Fertiliser
Apply a balanced fertiliser in spring when growth begins. A second diluted application may be useful in June-July. Avoid excess nitrogen, which reduces hardiness and leaf colouring.
Diseases and pests
Watch for powdery mildew and fire blight, especially in humid or enclosed conditions. Good air circulation, appropriate pruning and removal of affected parts limit problems. Aphids may affect young shoots in spring.
Did you know?
Photinia serratifolia is popular in Asia for its vibrant red spring foliage, symbolising new life and prosperity. Its white flowers resemble those of hawthorn, to which it is a distant botanical cousin within the Rosaceae family.
Where to buy it
Best planted in autumn so the roots settle in before summer, or in early spring once the frost has passed. Pick a plant with healthy foliage and roots that are not exposed. Best time: March, October, November.
