How to Grow Thumbelina Zinnias

When to Plant:

• Direct sow outdoors in late May, once soil is warm
• Do not start indoors – best sown where they are to bloom

Planting Instructions:

• Choose a sunny location with well-drained, organic soil
• Sow seeds shallowly, barely covering with soil
• Germination: 5–10 days under ideal conditions
• Thin seedlings to 25 cm (10") apart once they are 7.5 cm (3") tall

Care Tips:

• Water at the base to prevent leaf mildew
• Deadhead spent blooms to encourage continuous flowering
• For a long bloom period, sow in successive plantings throughout the season
