Verbena - Key Growing Information

SOWING: Transplant (recommended) — Sow 8-12 weeks before last frost. Cover seed lightly with growing medium. Seed is slow to germinate and sensitive to excess moisture, so keep growing medium on the dry side until emergence. Place seed trays on a heat mat during the day and remove at night to ensure the proper germination temperature. Transplant to cell packs or larger containers after true leaves appear. Harden off and transplant outside after the last frost. Direct seed — Direct seed only in areas with long growing seasons. Sow seeds after the last frost, barely covering seeds.
