DAHLIA XXL IN VARIETIES

Overview of Dahlia XXL Varieties

Dahlia XXL varieties are known for their large, showy blooms and bold presence in the garden. These hybrids are part of the Asteraceae family and are grown primarily for their stunning flowers, which can measure 15 cm (6 inches) or more in diameter. Available in a wide array of colours including red, yellow, orange, pink, purple, and white, Dahlia XXL types are especially popular in borders, containers, and as cut flowers.

These dahlias typically grow to a height of 60–90 cm, producing strong stems and lush foliage. They are tender perennials, meaning they require protection from frost and are often treated as annuals in colder climates.

Sunlight, Temperature & Positioning

• Sunlight Requirements:

  • Full sun is essential for optimal growth and flowering.

  • Choose a position that receives at least 6–8 hours of direct sunlight daily.

• Temperature Range:

  • Thrive in warm conditions with day temperatures of 20–25°C.

  • Sensitive to frost; plant out only after the last frost date has passed.

• Planting Site:

  • Ideal for sunny borders, raised beds, and large containers.

  • Position in a sheltered spot to avoid wind damage to tall stems and large blooms.

Soil, Watering & Feeding

• Soil Preferences:

  • Require fertile, well-drained soil enriched with compost or organic matter.

  • Avoid waterlogged conditions which may cause tuber rot.

• Watering Needs:

  • Water regularly, especially during dry periods.

  • Keep soil consistently moist but not soggy.

• Feeding Routine:

  • Apply a high-potassium fertiliser (such as tomato feed) every 2–3 weeks once buds appear.

  • Do not overfeed with nitrogen-heavy fertilisers, which can reduce flowering.

Maintenance, Flowering & Overwintering

• Staking:

  • Tall varieties benefit from support to prevent bending or breakage.

  • Use canes or plant supports early to avoid root disturbance later.

• Deadheading:

  • Remove spent flowers regularly to encourage continuous blooming.

  • Cut stems just above a leaf node to promote fresh growth.

• Bloom Period:

  • Flower from midsummer through to the first frosts.

  • Regular maintenance ensures a long, prolific display.

• Overwintering:

  • In colder regions, lift and store tubers after foliage has died back.

  • Clean and dry the tubers, then store them in a cool, dry place in sand or dry compost.

  • In milder climates, mulching heavily may allow them to remain in the ground.

Propagation, Pests & General Tips

• Propagation:

  • Can be propagated from tuber division in spring or by cuttings.

  • Each tuber section should include at least one eye or growing point.

• Common Problems:

  • Susceptible to slugs, snails, earwigs, and aphids.

  • Monitor regularly and use eco-friendly deterrents as needed.

• Care Tips:

  • Avoid overhead watering to reduce the risk of fungal diseases.

  • Encourage air circulation by spacing plants adequately
