Growing Tips

• Soil: Requires moist, humus-rich, well-drained acidic soil (pH 4.5–6.0). Does not tolerate alkaline or waterlogged conditions.

• Hardiness: Fully hardy across the UK.

• Watering: Water regularly, particularly during dry spells and in the first years after planting. Use rainwater where possible, especially in hard water areas.

• Care: Deadhead spent flower trusses carefully after blooming to encourage vigorous growth for the following season.

Pruning is rarely necessary but any shaping should be done immediately after flowering.
