How to Sow Giant Gaillardia Garden Flower Seeds in the UK
Giant Gaillardia, or blanket flower, is an eye-catching addition to any UK garden with its vivid red, orange, and yellow blooms. This hardy perennial thrives in sunny spots and is highly drought-tolerant, making it a great low-maintenance option for borders, containers, and wildflower areas. Growing to about 30 inches tall, it adds height, colour, and charm throughout summer and early autumn.
When and Where to Sow Giant Gaillardia Seeds
- Outdoor Sowing: Directly sow seeds in late spring (April to June) when the risk of frost has passed, and the soil has warmed. Choose a sunny location with well-drained soil.
- Indoor Sowing: Start seeds indoors 6–8 weeks before the last frost (February to April). Use pots or seed trays to create optimal germination conditions.
How to Sow Giant Gaillardia Seeds
- Sowing Depth: Sow seeds at a depth of 1/16 inch (barely cover the seeds) in fine, fertile soil.
- Spacing: If sowing directly outdoors, space seeds 12–18 inches apart to allow mature plants enough room to grow.
- Watering: Gently water the soil to keep it consistently moist but avoid overwatering, as soggy conditions can cause seed rot.
- Germination: Expect germination within 7–21 days when the soil temperature is between 18–21°C.
Caring for Giant Gaillardia Plants
- Sunlight Requirements: Gaillardia thrives in full sun and requires at least 6–8 hours of direct sunlight daily.
- Watering: Once established, Gaillardia is drought-tolerant and requires minimal watering. Only water during extended dry periods, as excessive moisture can cause root rot.
- Deadheading: Remove spent blooms regularly to encourage continuous flowering throughout the summer.
- Fertilising: Apply a light application of balanced fertiliser once in spring. Over-fertilising may result in excessive foliage growth and fewer blooms.
Harvesting and Long-Term Care
- Bloom Period: Flowers will bloom continuously for around 6–8 weeks from summer to early autumn.
- Self-Seeding: Allow some flowers to go to seed in autumn for natural reseeding or collect seeds for planting the following year.
- Winter Protection: Although Gaillardia is hardy, adding a layer of mulch in late autumn can help protect the roots during harsh winters.
