Photinia ‘Red Robin‘ (Photinia x fraseri) is a popular evergreen shrub known for its vibrant red foliage and versatility in garden design. If you’re considering adding this attractive plant to your garden, one of the most important factors to understand is the growth rate of the Red Robin.
How Fast Does Photinia ‘Red Robin’ Grow?
Once established, the Photinia ‘Red Robin‘ grows at a moderate rate of about 30cm (2-3 foot) per year. This makes it an excellent choice for those looking to create a medium-sized hedge or a striking standalone shrub. At full maturity, without pruning, the Red Robin can reach up to 4 meters (13 feet) in height and spread, making it a significant presence in any garden.
Factors Affecting Growth Rate
Several factors can influence the growth rate of your Photinia ‘Red Robin‘:
- Soil Type: While the Red Robin is adaptable, it thrives best in well-drained, loamy soil. It’s important to avoid heavy clay or waterlogged soils, which can stunt growth.
- Sunlight: For optimal growth, plant your Red Robin in a location that receives full sun to partial shade. Full shade should be avoided as it can lead to slower growth and less vibrant foliage.
- Watering: After the initial planting, Red Robin requires regular watering until it is well-established. Once established, it is quite drought-tolerant and requires minimal watering.
- Pruning: The Red Robin responds well to pruning, which can be done to control its size and shape. Regular pruning not only maintains its aesthetic appeal but also encourages denser foliage and more vigorous growth.
Pruning to Control Growth
If you prefer a smaller, more manageable shrub, pruning is key. Regular pruning can keep your Photinia ‘Red Robin‘ at a height of 1.2 meters (4 feet) or less. Pruning is typically recommended once or twice a year, ideally in early to mid-June after the flowering period. Avoid pruning after late July to prevent the new shoots from being damaged by early frosts.
Red Robin as a Hedge
When used as a hedge, the Red Robin should be planted about 75cm (2.5 feet) apart for a dense, quick-growing hedge. While it makes a beautiful hedge, it is worth noting that Red Robin hedges are not suitable as a barrier hedge due to the lack of thorns and the plant’s ability to be easily parted.
Conclusion
The Photinia ‘Red Robin‘ is a versatile and attractive choice for gardeners looking for a vibrant evergreen shrub with a manageable growth rate. Whether you choose to let it grow to its full height or keep it neatly trimmed, understanding its growth rate and the factors that influence it will help you make the most of this popular plant in your garden.
