Sow Siberian Motherwort seeds indoors in early spring or directly outdoors in the garden after the last frost. If starting indoors, use seed trays or small pots with well-draining soil. Plant the seeds at a depth of about 6 mm in the soil. Press them gently into the soil.
Germination typically takes 14-21 days. Maintain a temperature of around 15-21°C for optimal germination. Provide bright, indirect light for the seedlings.
Transplant seedlings outdoors after the last frost. Space them about 30-45 cm apart. Choose a well-drained location for planting. Siberian Motherwort can tolerate a variety of soil types but prefers slightly alkaline to neutral soil.
Plant in a location that receives full sun to partial shade.
Siberian Motherwort has a tendency to self-seed. If you want to control its spread, remove spent flowers before they produce seeds.
