How to Sow Snowball Daisy Seeds in the UK
Snowball daisies are a stunning addition to any garden, producing abundant white, double blooms on tall stems. These short-lived perennials thrive in borders, pots, containers, and flower beds, adding a touch of elegance with their fragrant flowers and lush green foliage. With a mat-forming growth habit, snowball daisies will self-seed if left undisturbed, making them an excellent choice for cottage-style gardens or mixed herbaceous borders.
When and Where to Sow Snowball Daisy Seeds
- Indoor Sowing: Start seeds indoors between late winter and early spring (February to April) for an extended blooming period. Use seed trays or small pots placed in a bright, warm location.
- Outdoor Sowing: Direct sow outdoors after the last frost has passed (May onwards) when the soil is warm and workable. Choose a sunny, well-drained location for best results.
Ideal Growing Conditions for Snowball Daisies
- Soil Requirements: Prefers light, well-drained, fertile soil enriched with compost. Avoid heavy or waterlogged soil, which can hinder root development.
- Sunlight: Thrives in full sun, producing the most blooms in bright conditions. Tolerates partial shade, though flowering may be reduced.
- Temperature: Ideal germination temperature is 18-21°C (65-70°F). Established plants can tolerate cooler UK temperatures but may need winter protection.
How to Sow Snowball Daisy Seeds Indoors
- Prepare Containers: Fill seed trays or small pots with fine, well-draining seed compost.
- Sowing Depth: Sow seeds 6 mm (ÂĽ inch) deep and cover lightly with compost. Snowball daisy seeds require light to germinate, so avoid burying them too deeply.
- Moisture and Humidity: Keep compost moist but not waterlogged. Place trays in a bright location, such as a windowsill or greenhouse.
- Germination Conditions: Maintain a temperature of 18-21°C. Germination occurs within 10-15 days.
- Thinning and Transplanting: Once seedlings reach 10 cm (4 inches) in height, transplant them to larger pots or their final growing location. Harden off over 7-10 days before moving outdoors.
How to Sow Snowball Daisy Seeds Outdoors
- Soil Preparation: Loosen the soil with a rake and remove weeds before sowing.
- Sowing Depth: Scatter seeds thinly across the soil or sow in rows spaced 20-30 cm apart. Cover lightly with soil to allow some light exposure for germination.
- Watering: Water gently to keep the soil moist but not soggy. Avoid overwatering, as excess moisture can slow germination.
- Thinning Seedlings: Once seedlings are established, thin them to 15-20 cm (6-8 inches) apart for proper airflow and growth.
Caring for Snowball Daisy Plants
- Watering: Keep the soil consistently moist, especially during dry spells. Mature plants are relatively drought-tolerant but still benefit from regular watering.
- Feeding: Apply a balanced general-purpose fertiliser once during the growing season for healthier blooms.
- Deadheading: Remove spent flowers regularly to encourage prolonged blooming. Allow some flowers to self-seed if you want natural regrowth.
- Overwintering: Snowball daisies are short-lived perennials and may not survive harsh winters. Apply mulch around the base in autumn for extra protection.
