🌿 How to Care for Salvia ‘So Cool Purple’

How do I prune Salvia ‘So Cool Purple’?

Water Salvia ‘So Cool Purple’ regularly during dry spells, particularly newly planted ones. Established hardy salvias are drought-tolerant but benefit from deep watering during prolonged hot periods. Avoid waterlogging, as it can cause root rot.
Salvia ‘So Cool Purple’ require light feeding in spring with a balanced slow-release fertiliser or compost. Tender salvias benefit from fertilisation every 2–4 weeks during the growing season using a liquid feed for flowering plants. Over-fertilising should be avoided, as it can encourage foliage growth at the expense of flowers.
Propagation of Salvia ‘So Cool Purple’is prohibited without a licence
Salvia ‘So Cool Purple’ should be trimmed around April or May, a technique often called the “Chelsea Chop,” once new shoots start to appear. Cut back to the fresh growth, and continue deadheading throughout the season. Vigorous varieties can be pruned again in July to encourage bushier, greener plants rather than tall, woody stems. Salvias should not be cut back in autumn, as leaving the foliage intact helps protect the plant from frost.
Salvia ‘So Cool Purple’ moderately drought-tolerant once established, thriving in well-drained soil and full sun. Tender salvias are less drought-tolerant and require more consistent watering.
Salvia ‘So Cool Purple’ performs well in UK gardens if given full sun and free-draining soil. It’s hardy in most areas, flowers for months in summer and autumn, and suits borders or containers. Avoid winter wet and prune lightly in spring.
