When to Sow Mixed Colour Daisy Seeds

• Outdoor Sowing: Sow directly outdoors in late spring (May), once the risk of frost has passed, and the soil has warmed up. 

Step-by-Step Guide to Sowing Mixed Colour Daisy Seeds 

Indoor Sowing 

1. Prepare Containers: Fill seed trays or small pots with fine-textured seed compost. 
2. Sowing the Seeds: Sprinkle the seeds sparingly on the surface of the compost. Cover lightly with a thin layer of seed compost (no more than 1/8 inch) as the seeds require light to germinate. 
3. Germination Conditions: Place the containers in a warm, well-lit area, such as a windowsill or propagator. Maintain a temperature between 18-21°C (64-70°F). 
4. Watering: Keep the compost moist but not waterlogged. Water only when the surface begins to dry out to avoid overwatering. 
5. Germination Period: Germination typically takes 10-21 days under optimal conditions. 

Outdoor Sowing 

1. Soil Preparation: Choose a sunny or partially shaded spot with well-drained soil. Loosen the soil and remove any weeds or debris. 
2. Sowing the Seeds: Scatter seeds directly onto the prepared soil surface. Lightly rake or press them into the soil without fully covering them, as light aids germination. 
3. Watering: Water gently after sowing to settle the soil. Keep the area moist but avoid waterlogging. 

Caring for Mixed Colour Daisy Plants 

• Transplanting: When indoor seedlings reach a height of about 5 inches and have developed strong roots, transplant them to their final location. Gradually harden them off by exposing them to outdoor conditions for 7-10 days before planting outside. Space the plants about 2 inches apart for compact growth or wider for a spreading effect. 
• Watering: Water regularly during dry periods, but avoid overwatering as daisies prefer well-drained soil. 
• Sunlight: Daisies thrive in full sun to partial shade. Ensure they receive at least 6 hours of sunlight daily for the best blooms. 
• Feeding: Apply a balanced fertiliser every 4-6 weeks during the growing season to encourage vibrant flowers and healthy foliage. 

Maintaining Mixed Colour Daisies 

• Deadheading: Remove spent blooms regularly to prolong the flowering period and encourage new growth. 
• Weeding: Keep the area around the plants weed-free to reduce competition for nutrients and water. 
• Self-Seeding: Allow a few flowers to go to seed at the end of the season if you wish to encourage self-seeding for blooms the following year.
