How to Grow Photinia 'Red Robin'
Photinia × fraseri
Photinia 'Red Robin' is a popular evergreen shrub grown for its vivid red new growth. Plant in full sun for the best leaf colour in any well-drained soil. Trim after the red flush fades in late spring and again in late summer to encourage fresh red growth. Leaf spot is the main problem — rake up fallen leaves, improve airflow, and avoid overhead watering. Makes an excellent hedge or specimen shrub and responds well to hard renovation pruning.

☀️ Light
Full sun for best red leaf colour
Full sun to partial shade. Best red foliage colour develops in full sun. Tolerates some shade but growth becomes leggy.
💧 Watering
Regular until established, then drought-tolerant
Water regularly during the first two years to establish. Once established, tolerates dry spells well. Avoid waterlogged soil.
🌱 Fertilizing
Balanced feed in spring, mulch with compost
Apply a balanced fertiliser in spring. Mulch with compost to retain moisture and suppress weeds.
✂️ Pruning
Trim after red flush fades, again in late summer
Trim after the red new growth fades in late spring. A second trim in late summer encourages a fresh flush of red leaves. Can be hard pruned to renovate.
🍂 Mulching
Mulch in spring to retain moisture
Mulch in spring with garden compost or bark chips, keeping it away from the stem base.
Growing Tips
Trim for colour
Trim after the red new growth fades in late spring; a second trim in late summer triggers another red flush.
Clear fallen leaves
Rake up and destroy fallen leaves promptly to reduce the spread of photinia leaf spot.
Airflow beats leaf spot
Avoid overhead watering and ensure good airflow through hedges to limit fungal leaf spot.
Hard prune to renovate
Can be hard pruned to renovate an overgrown or bare-legged specimen; it regenerates well from old wood.
Pests & Diseases
Pest Aphids
Identification: Clusters of green or black aphids on young red shoots. Sticky honeydew and distorted leaves.
- Encourage ladybirds, lacewings, and hoverflies
- Spray with insecticidal soap
- Blast off with a strong jet of water
- Spray with a pyrethrin-based insecticide if heavy infestations persist
Pest Scale Insects
Identification: Small brown or white oval bumps on stems. Sticky honeydew and sooty mould on leaves below.
- Scrub off scale with a soft brush in winter
- Apply a winter plant oil wash
- Encourage parasitic wasps and ladybirds
- Spray with a plant oil-based insecticide during the dormant season
Pest Vine Weevil
Identification: Irregular notches around leaf margins (adult feeding). Wilting despite moist soil suggests larval root damage.
- Apply biological control nematodes (Steinernema kraussei) to soil in spring or autumn
- Check containers for C-shaped white grubs when repotting
- Hand-pick adults at night with a torch
- Drench containers with a systemic insecticide containing acetamiprid
Disease Photinia Leaf Spot Entomosporium maculatum
Symptoms: Dark red or brown spots on leaves, often with a purple margin. Spots merge in wet weather. Severe cases cause heavy leaf drop.
Treatment: Rake up and destroy fallen leaves. Prune out badly affected growth. Improve air circulation.
Prevention: Avoid overhead watering. Prune hedges to allow airflow. Clear fallen leaves promptly.
Disease Fire Blight Erwinia amylovora
Symptoms: Shoots wilt and turn brown or black as if scorched. Cankers may ooze bacterial slime in wet weather.
Treatment: Cut out affected branches at least 60 cm below visible symptoms. Sterilise tools between cuts.
Prevention: Avoid high-nitrogen feeds. Prune in dry weather. Disinfect tools.
