How to Germinate Great Mullein

How to Germinate Great Mullein (Verbascum thapsus)

  • Sow Great Mullein seeds directly outdoors in early spring or fall, as they prefer cooler temperatures for germination.
  • Choose a location with full sun and well-draining soil. Great Mullein can tolerate poor and rocky soils.
  • Scatter seeds on the soil surface and press them down lightly; do not cover, as they need light to germinate.
  • Keep the soil moist but not waterlogged during the germination period, which typically takes 14-21 days.
  • If starting seeds indoors, sow them 6-8 weeks before the last frost and transplant them outdoors once the soil has warmed.
  • Thin or transplant seedlings to 12-18 inches apart once they have developed a few true leaves to allow space for growth.

Additional Tips

  • Great Mullein prefers full sun and is highly drought-tolerant once established, requiring minimal watering.
  • Apply a light layer of mulch around the base of the plants to retain moisture and control weed growth.
  • Deadhead spent flowers to encourage continuous blooming and prevent excessive self-seeding.
  • Great Mullein is a biennial plant; it forms a rosette of leaves in the first year and blooms in the second year.
  • Cut back the flower stalks after they finish blooming to keep the garden tidy and prevent unwanted spreading.
