Care Guide
Watering
Water deeply during dry spells, allowing the soil to dry out somewhat between waterings. Established plants are relatively drought-tolerant.
Sunlight
Plant in a location that receives full sun for best flowering performance, though they can tolerate light partial shade.
Soil and Fertilizer
Lupins prefer acidic, well-draining sandy or loamy soils. Avoid high-nitrogen fertilizers as they fix their own nitrogen.
Pruning
Deadhead spent flower spikes to encourage a second round of bloom and prevent unwanted self-seeding.
Propagation Methods
Seed
Nick the seed coats or soak them in warm water for 24 hours before sowing in spring to improve germination rates.
