Caring for Red Robin

Water red robin regularly during its first growing season to establish a strong root system—aim for a thorough soak once or twice a week if rainfall is scarce. Once established, it has moderate water needs and tolerates short dry spells, but in prolonged summer drought give it a deep watering every ten days to prevent leaf scorch and stress. Reduce watering in autumn and winter; the evergreen foliage means it still transpires, but waterlogged roots in cold weather invite root rot. Feed in March and April with a balanced general-purpose fertiliser (such as Growmore or blood, fish and bone) scattered around the base at the rate recommended on the packet. This supports the vigorous spring growth and enhances the intensity of the red foliage. A second, lighter feed in early summer can be beneficial if growth seems sluggish, but avoid feeding after July as soft late growth is vulnerable to frost damage. Red robin is hardy in zones 7a–9b but can suffer in very cold, exposed sites or harsh winters. A thick mulch layer helps insulate roots, and planting in a sheltered spot reduces wind scorch on the evergreen leaves. The main pest problem is aphids on soft new growth in spring; a strong jet of water or an insecticidal soap usually deals with them. The most common disease is Photinia leaf spot, which causes dark blotches on older leaves. Remove and bin affected foliage promptly, avoid overhead watering, and ensure good air circulation by not overcrowding plants. In wet seasons, fungal issues are more prevalent, so vigilance and garden hygiene—clearing fallen leaves—are important throughout the year.
