To start mullein from seeds, follow these tips:
- Seed Stratification: Mullein seeds benefit from cold stratification. You can achieve this by sowing seeds outdoors in the fall, allowing them to naturally experience cold temperatures over winter, or by placing seeds in a refrigerator for 4-6 weeks before planting.
- Planting Time: Direct sow seeds in the fall or start them indoors 6-8 weeks before the last expected frost date in your area. Surface sow the seeds (they require light to germinate) and lightly press them into the soil. Seeds should be scattered on the surface or sown 1/16 inch deep.
- Soil Preparation: Choose a site with well-drained soil. Mullein can grow in poor soil but prefers a sunny location. Scratch up the soil lightly to prepare the surface for planting.
- Watering: Keep the soil moist when growing mullein from seed, especially as it starts to flower. Once established, mullein is drought-tolerant and requires minimal watering.
- Spacing: Thin seedlings so that mature plants are 20-24 inches apart. This ensures each plant has enough space to grow and thrive.
- Germination: Seeds will germinate in 12-15 days under ideal conditions. Monitor the area for sprouts and thin as necessary.
- Transplanting: Once the danger of frost has passed, transplant indoor seedlings to the garden. Ensure they are spaced appropriately and watered regularly until they establish themselves.
By following these steps, you can successfully grow mullein from seeds, enjoying its ornamental beauty and potential medicinal benefits in your garden.
