Strawflower - Key Growing Information
DAYS TO GERMINATION: 7-10 days at 70-75°F (21-24°C).
SOWING: Transplant — Sow 6-8 weeks before last frost. Do not cover seed as light is required for germination. Bottom water or mist to avoid covering seeds with displaced soil. Transplant to cell packs or larger containers when the first true leaves appear. Harden off and transplant outside after the danger of frost has passed. Direct seed — Sow after last frost, only where summers are very long. Trellis, such as Hortonova, used as horizontal support, may be necessary.
