garden explosion of elegance

Dahlia 'Perfect Pom Pom Collection' brings a burst of colour and texture to your garden with its iconic spherical blooms. Dahlias are herbaceous perennials native to Mexico and Central America, prized for their showy flowers and long blooming period. The pompom variety is known for its tightly packed, globe-shaped petals that create a dramatic effect both outdoors and in floral arrangements.

Growing Guide

• Planting Time: Plant tubers outdoors after the last frost (typically late April to May).
• Location: Prefers full sun but will tolerate partial shade; choose a sheltered spot to protect from strong winds.
• Soil: Well-drained, fertile soil is best; add organic matter to enrich poor soils.
• Watering: Water regularly during dry spells but avoid waterlogging.
• Mature Size: Typically reaches 60–100cm in height depending on growing conditions.

Seasonal Care Tips

• Pest Management: Watch for slugs and snails when shoots emerge in spring.
• Deadheading: Remove spent blooms to encourage new flowers and prolong the display.
• Lifting Tubers: In colder regions (below USDA zone 8), lift tubers after the first frost and store them in a cool, dry place over winter.

Design Inspiration & Companion Planting

• Dahlias pair beautifully with ornamental grasses, salvias, rudbeckias, and cosmos for a classic cottage garden look.
• Their upright form makes them perfect for the middle or back of mixed borders.

FAQs

• When should I plant my Dahlia tubers?
  The best time is after the last frost in spring—usually late April or early May in the UK.
• How long will they flower?
  Dahlias bloom from midsummer through to the first frosts, providing months of colour.
• Do I need to lift the tubers each year?
