Growing Instructions

How to Germinate Marshmallow (Althaea officinalis)
  • Sow seeds indoors 4–6 weeks before the last expected frost date, or directly outdoors after danger of frost has passed.
  • Scarify seeds gently or soak in warm water for 12–24 hours to improve germination.
  • Plant seeds ¼ inch (6 mm) deep in moist, well-draining soil.
  • Space plants about 18–24 inches (45–60 cm) apart to allow room for growth.
  • Maintain a soil temperature of 60–70°F (16–21°C) for best results.
  • Germination typically occurs in 10–21 days.
  • Keep the soil consistently moist, but not waterlogged, during the germination period.

Additional Tips
  • Marshmallow prefers full sun to partial shade and thrives in moist, rich, loamy soil.
  • Water regularly, especially during dry periods—this plant enjoys damp conditions.
  • Mulch around the base to help retain soil moisture and suppress weeds.
  • Marshmallow is a perennial and can return each year with proper care.
  • The roots, leaves, and flowers have traditional medicinal uses and can be harvested in the second year.
