Planting & Care

To improve germination, nick the seed coat with a file or sandpaper and soak seeds in water for 24 hours before sowing. For best results, cold stratify seeds by placing them in a moist medium in the refrigerator for 4-6 weeks. Sow seeds indoors 6-8 weeks before the last frost or directly outdoors in early spring. Cover lightly with soil and keep consistently moist at around 65-70°F (18-21°C). Germination can be slow and uneven, typically taking 14-30 days.

Once seedlings have several true leaves, transplant them to individual pots or into the garden after the danger of frost has passed. Space plants 12-18 inches apart in a sunny location with well-drained soil. Water regularly during establishment, then reduce frequency as plants mature. Mulch around plants to retain moisture and suppress weeds. Deadhead spent blooms to encourage continued flowering and prevent self-seeding if desired. Lupines benefit from a light application of compost in spring.
