Fertilising a Photinia × fraseri 'Red Robin'
To support the robust growth and maintain the vibrant foliage of >Photinia fraseri 'Red Robin', it is essential to provide the right nutrition. This species thrives with an application of a balanced, slow-release fertilizer formulated for evergreen hedges, which should be applied in early spring to kickstart the growth cycle.
Given its growth rate of 30-50 cm per year, additional feeding in mid-summer can be beneficial to sustain its development. When fertilizing, distribute the product evenly around the base of the hedge, following the manufacturer's directions for the quantity. Avoid over-fertilization, as this can lead to excessive growth, making the hedge more susceptible to winter damage, especially in areas where it can face temperatures as low as -20.6°C, within USDA zone 6a.
