Tips on How to Grow Verbena from Seeds

Germination

• Start Verbena  - sow seeds about 8-12 weeks before the last frost date.

• Cover seed lightly with growing medium. 2-3 seeds per individual peat or fiber pots.
• Seed is slow to germinate (10-30 days)  and sensitive to excess moisture, so keep growing medium on the dry side until emergence.
• Place seed trays on a heating mat during the day and remove at night to ensure the proper germination temperature. Alternating temperatures between 60°F at night and 86°F during the day helps to break dormancy.
• Transplant to cell packs or larger containers after true leaves appear. Harden off and transplant outside after the last frost.
• Direct seed only in areas with long growing seasons. Sow seeds after the last frost, barely covering seeds.
• Verbena needs 8-10 hours of direct sunlight every day and a well-drained soil. Plants that are kept too moist and don’t get enough sun are susceptible to powdery mildew and other diseases. Plant verbena in the sunniest location in your garden to prevent this problem.
