When it comes to growing forget-me-nots, it is relatively easy. They are mostly grown as an annual by starting seeds in pots indoors. As long as you provide a nutrient-dense soil that is organically rich in all essential elements the plant needs for growth it will grow easily without causing trouble.
You must also take care of the watering routine and provide a shaded area for better growth. However, if they are out of their comfort zone, then they may cause some fuss during the growing period.
