When to Plant Verbena Seeds
Start Verbena indoors 8-10 weeks before the last frost of the season, or sow directly into the garden after the last frost of the season has passed.
Where to Plant Verbena Seeds
Plant Verbena in average, well draining, moist, acidic soils with access to full sun (6-8 hours of sun per day). Once established, Verbena has a good tolerance to heat and drought, making it suitable for areas that are exposed to such conditions. Verbena also has a tendency to spread, so keep that in mind when locating an area for planting.
How to Plant Verbena Seeds
Spread Verbena seeds into moistened soil via broadcasting over the planting area. Lightly cover the seed no deeper than 1/8th of an inch; light is not required to germinate the seeds. When started indoors, transplant each Verbena 8-12 inches apart.
How to Care for Verbena
Younger plants can be pinched to encourage a bushier habit, and spent flowers can be deadheaded to encourage a new flush of bloom. Cuttings can be taken from mature plants in the late summer months and kept indoors for the next season.
