🌿 How to Care for Salvia x sylvestris ‘Viola Klose’

How do I prune Salvia x sylvestris ‘Viola Klose’?

Salvia x sylvestris ‘Viola Klose’ should be left through the winter, as the dead wood protects them from frost. They can be pruned in early spring, and more vigorous varieties may be trimmed again around June.

What are the common pests and diseases affecting Salvia x sylvestris ‘Viola Klose’?

Salvia x sylvestris ‘Viola Klose’ can be susceptible to aphids, capsid bugs, whitefly, sage leafhoppers, and glasshouse red spider mites. Additionally, fungal issues like grey mould (Botrytis) can develop in cool and damp conditions, especially during overwintering.

How often should I water Salvia x sylvestris ‘Viola Klose’?

Water Salvia x sylvestris ‘Viola Klose’ 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.

Do Salvia x sylvestris ‘Viola Klose’ need feeding?

Salvia x sylvestris ‘Viola Klose’ 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.

Should I deadhead or cut Salvia x sylvestris ‘Viola Klose’ back?

Salvia x sylvestris ‘Viola Klose’ 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.

How do I propagate Salvia x sylvestris ‘Viola Klose’?

Salvia x sylvestris ‘Viola Klose’ can be propagated from cuttings, seeds, or by division. Softwood cuttings can be taken in summer or semi-ripe cuttings in late summer; remove lower leaves, dip in rooting hormone, and plant in a moist, free-draining medium. Seeds can be sown indoors 8–10 weeks before the last frost, germinating at 18–22°C, and seedlings should be transplanted after the last frost. Clump-forming hardy salvias can be divided every 3–4 years in early spring or autumn.

Are Salvia x sylvestris ‘Viola Klose’ drought-hardy?

Salvia x sylvestris ‘Viola Klose’ moderately drought-tolerant once established, thriving in well-drained soil and full sun. Tender salvias are less drought-tolerant and require more consistent watering.

Are Salvia x sylvestris ‘Viola Klose’ good in UK gardens?

Salvia x sylvestris ‘Viola Klose’ 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.
