Zinnia

Description

When to Plant Zinnias

• It’s recommended that you grow zinnia from seed right in the garden bed, as they do not like to be transplanted. From seed, they will grow very quickly in the right conditions.
  • Note: Zinnias can be started from seed indoors if you prefer—just transplant them while they’re young and do so carefully.
• Zinnias are sensitive to frost, so do not seed until the last frost has passed in your area.
• Zinnias will grow in a minimum daytime temperature of about 60°F (16°C), though a range of 74–84°F (23–28°C) is preferred.
• Sow a round of seeds every week or so for several weeks to extend the flowering period.
