What you need to know to Plant & Grow
Lupins have hard seed coats and germinate best under cool conditions.
-
Seed Preparation: Soak seeds in water for 24 hours prior to sowing to soften the tough seed coat and kickstart germination.
-
Indoor Sowing: Start indoors 6 to 8 weeks before your last expected spring frost date. Sow in a quality soilless growing medium and keep at a cool temperature of 16°C throughout the 20 day germination period. Keep sprouted seedlings under grow lights at 16°C before hardening off and carefully transplanting outdoors after the risk of frost has passed.
-
Outdoor Direct Sowing: Direct sow seed outdoors in late fall to allow winter weather to condition the seeds naturally for spring sprouting.
-
Care & Maintenance: Plant in moist soil in full sun to partial shade. Protecting plants from severe winter cold and extreme summer heat helps prolong their life and vigorous flowering habit year after year.
