Press shallow-sown seed into good soil contact and keep the seed zone from drying during establishment. Thin or transplant only when the growth habit and spacing call for it. Leave enough room for mature width and air movement. Bloom timing and final height can shift with sowing date, climate, soil, moisture, and competition, so use listed figures as planning ranges.\u003c\/p\u003e\n\u003cp\u003eCover 1\/4\", keep moist and provide a strong light source.\u003c\/p\u003e\n\u003cp\u003eTransplant 3\" apart in larger containers when able to handle.\u003c\/p\u003e\n\u003cp\u003eSoil Temperature: above 50°F Planting Depth: 1\/4\" Germination: 21-28 Days Height At Maturity: 18-24\" Sun\/Shade: Full Sun Spacing After Thinning: 10-12\" Approx Seeds per Pack: 50 Seeds\u003c\/p\u003e\n\u003cp\u003ePlace ‘Heirloom Blue Mirror’ Chinese Delphinium where its recorded height and growth habit fit the surrounding planting. Shorter companions can be positioned toward bed edges, while taller stems need room where they will not shade small seedlings too early. If cutting flowers, harvest with clean tools at the stage appropriate to the bloom form. If leaving flowers in place, observe how bloom sequence changes through the season and record which sowing date performed best at the site.\u003c\/p\u003e\n\u003cp\u003eExplore related options in our \u003ca href=\"\/collections\/flower-seeds\"\u003eFlower Seeds\u003c\/a\u003e.\u003c\/p\u003e","brand":"Renee's Garden","offers":[{"title":"Default Title","offer_id":21544907341937,"sku":"SWF5346","price":3.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0061\/1391\/9089\/products\/renee-s-garden-delphinium-chinese-blue-mirror.jpg?v=1747083019","url":"https:\/\/www.groworganic.mom\/products\/renee-s-garden-delphinium-chinese-blue-mirror","provider":"Grow Organic","version":"1.0","type":"link"}
