Polyanthus Primrose

Surface-sow tiny seeds on moist, sterile mix and cold-stratify at 35–40°F for 3–4 weeks to break dormancy, then move to 65°F for germination. Grow on at cool temperatures (55–60°F) since heat causes etiolation; transplant into partial shade in humus-rich, moist, well-drained soil in early spring. Primroses bloom best in cool, moist conditions — they are outstanding spring plants but typically go dormant in summer heat. Divide crowded clumps after bloom in spring and replant divisions in refreshed, compost-amended soil. Спосіб посадки: Посів на розсаду вдома Відстань між рослинами: 9–12 дюймів Висота: 6–10 дюймів Дні до схожості: 14–28 Температура ґрунту для схожості: 13–18°C
