Plant seeds 1\/4 inch deep in a sunny location with well-drained soil. Keep the soil moist until germination, which typically occurs in 2-4 weeks. Once seedlings are established, thin them to 12-18 inches apart. Water regularly during the first growing season, then reduce frequency as plants become drought-tolerant. Mulch around plants to conserve moisture and suppress weeds.\u003c\/p\u003e\u003cp\u003eRiverbank Lupine requires little maintenance. Deadhead spent flowers to encourage additional blooms and prevent unwanted self-seeding. In late fall, cut back foliage after it dies back. These plants benefit from a light application of compost in early spring. Avoid overwatering, as lupines are susceptible to root rot in poorly drained soils.\u003c\/p\u003e\u003ch2\u003eWhat's Included\u003c\/h2\u003e\u003cp\u003e25 Riverbank Lupine seeds (Lupinus rivularis).\u003c\/p\u003e","brand":"Blake's Flora \u0026 Soil","offers":[{"title":"Default Title","offer_id":67824610476342,"sku":"FOLIA2-744","price":27.4,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0994\/4884\/8694\/files\/il_fullxfull.7479710137_9bo6.jpg?v=1793003628","url":"https:\/\/blakesflora.com\/products\/25-riverbank-lupine-seeds-blue-lupinus-for-spring-bloom-spikes","provider":"Blake's Flora \u0026 Soil","version":"1.0","type":"link"}
