How to Germinate Bigroot Geranium Seeds:

Geranium macrorrhizum seeds benefit from cold stratification for best germination rates:

1. Cold Stratification: Mix seeds with moist sand or vermiculite in a sealed plastic bag. Refrigerate at 35-40°F for 4-6 weeks to break dormancy.
2. Sowing: After stratification, sow seeds on the surface of well-draining seed starting mix. Lightly cover with a thin layer of vermiculite or fine soil (about 1/8 inch).
3. Temperature: Maintain soil temperature at 65-70°F for optimal germination.
4. Moisture: Keep soil consistently moist but not waterlogged. Mist regularly to maintain even moisture without saturating the medium.
5. Germination Time: Seeds typically germinate in 2-4 weeks after stratification, though some may take longer.
6. Transplanting: Once seedlings develop 2-3 true leaves and are sturdy enough to handle, transplant to individual pots.
7. Growing On: Grow seedlings in bright indirect light. Gradually acclimate to outdoor conditions before planting out.

Planting Tips: Plant in partial to full shade in well-draining soil. Tolerates a wide range of soil types once established. Ideal for USDA zones 3-8. Space 12-18 inches apart for groundcover effect. May bloom in the first or second year from seed. Spreads readily to form attractive colonies.
