Salvia Plant Care Guide: Everything You Need to Know

Salvias are a gardener’s favourite for their vibrant flowers, long blooming season, and ability to attract pollinators. Whether you’re planting them in borders, pots, or mixed beds, salvias bring colour and life to any outdoor space. In this guide, we’ll answer the most common questions about growing and caring for salvias.

Do Salvias Come Back Every Year?

Many salvias are perennials, meaning they return year after year, especially in mild climates.

Hardy varieties like Salvia nemorosa and Salvia x sylvestris will survive colder winters.
Tender types such as Salvia splendens or Salvia patens may need protection or be treated as annuals.

Tip: Mulch around the base in late autumn to protect roots from frost.

Where Is the Best Place to Plant Salvias?

Salvias thrive in well-drained soil and prefer a spot with good air circulation.

Ideal locations include sunny borders, raised beds, or containers.
Avoid areas prone to waterlogging, as salvias dislike wet roots.

Do Salvias Like Sun or Shade?

Salvias love full sun.

Aim for 6–8 hours of direct sunlight daily for the best flowering.
While some varieties tolerate light shade, too much shade can reduce blooms and make plants leggy.

Do You Cut Back Salvias in the Autumn?

Yes, pruning salvias helps maintain health and encourage new growth:

Hardy salvias: Cut back stems to just above ground level after flowering or in late autumn.
Tender salvias: Trim lightly and overwinter indoors or in a greenhouse.

Removing spent flowers during the season also promotes continuous blooms.

Do Salvias Spread?

Salvias generally form neat clumps but can spread gradually:

Most varieties grow 30–90 cm wide, depending on type.
They’re not invasive, but they will fill out nicely over time.

Should Salvias Be Grown in Pots or Ground?

Both options work well:

Pots: Great for tender salvias or small spaces. Use a free-draining compost and water regularly.
Ground: Perfect for hardy varieties in borders or mixed beds. Ensure soil drains well to prevent root rot.
