What you need to know to Plant & Grow
Lupins have hard outer seed coats and germinate best under cool temperatures.
-
Seed Preparation: Soak seeds in water for 24 hours prior to sowing to soften the hard seed coat and encourage uniform germination.
-
Indoor Sowing: Start seeds indoors 6 to 8 weeks before your last spring frost date. Sow in a quality soilless growing medium and maintain a cool temperature of 16°C for the 20 day germination period. Move sprouted seedlings under lights at 16°C before hardening off and carefully transplanting outdoors after frost danger passes.
-
Outdoor Direct Sowing: Direct sow seed outdoors in late fall for natural winter stratification and robust spring emergence.
-
Care & Placement: Plant in moist, well-drained soil in full sun or light shade. Avoid disturbing root systems after planting out.
