Forget-me-nots are propagated by sowing seeds, less often by division or shoot cuttings.
Seeds are sown in summer, then flowering plants are obtained in the spring of the next year, spring sowing rarely produces individuals that bloom in the same year. The seeds germinate the fastest at a temperature of 20-22 ° C, then emergence appears 15-25 days after sowing.A temperature of 9-12 ° C is sufficient for further growth.
After emergence, the seedlings should be pierced individually into the pots, and in autumn they should be planted permanently, with a spacing of 20-25 cm. In summer, the plants should be provided with the coolest possible place, e.g. in the shade or at a northern location.
