For best results, cold stratify seeds by placing them in a moist medium in the refrigerator for 4-6 weeks. Sow seeds indoors 6-8 weeks before the last frost or directly outdoors in early spring. Cover seeds lightly with soil and keep consistently moist until germination, which typically occurs in 14-30 days at 65-70°F (18-21°C).\u003c\/p\u003e\u003cp\u003eTransplant seedlings outdoors after the danger of frost has passed, spacing them 12-18 inches apart in well-drained soil. Water regularly during establishment, then reduce frequency as plants mature. Apply a layer of mulch to retain moisture and suppress weeds. Deadhead spent blooms to encourage additional flowering and prevent unwanted self-seeding. In hot climates, provide afternoon shade to protect plants from intense heat.\u003c\/p\u003e\u003ch2\u003eWhat's Included\u003c\/h2\u003e\u003cp\u003e25 Neptune Lupine seeds for planting.\u003c\/p\u003e","brand":"Blake's Flora \u0026 Soil","offers":[{"title":"Default Title","offer_id":67824611230006,"sku":"FOLIA2-748","price":27.4,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0994\/4884\/8694\/files\/il_fullxfull.7429233342_dxb4.jpg?v=1793003632","url":"https:\/\/blakesflora.com\/products\/25-neptune-lupine-seeds-purple-lupinus-variety-for-spring-garden-planting","provider":"Blake's Flora \u0026 Soil","version":"1.0","type":"link"}
