Before sowing Lupine seeds, soak seed in warm water for 24 hours. The soaking will aid in germination. Lupine seeds can be sown outdoors after danger of frost. In prepared soil, sow 3 - 4 seeds together, spacing them 18 - 24 inches apart. Cover lightly and keep seed moist. Thin to strongest plant when they reach 2 inches. For the first season, water Lupines well after planting and maintain 1 inch of water, once per week. Following this water routine the first year will ensure deep root establishment. The following years, as the Lupine plant matures, they will acclimate and use what water is provided by the environment and should only need irrigation during periods of prolonged heat and drought. |
