🌱 How to Care for Red Robin Photinia to Prevent Leaf Spot?

💧 How to Water

Water deeply once a week during the first growing season, then reduce frequency once established, letting the topsoil dry between waterings. Avoid wetting the foliage when watering, as damp leaves encourage fungal leaf spot.

☀️ Lighting

Full sun brings out the most intense red new growth and keeps the shrub compact; it will also grow in partial shade but with less vivid color and a looser habit.

🪴 Ideal Soil

Use fertile, well-drained soil enriched with organic matter. Photinia tolerates a wide range of soil types but performs poorly in soil that stays waterlogged.
