Forget-me-not flowers are actually a plant genus consisting of about 50 different species. They cannot survive winter temperatures and usually only live for one season, but they can self-sow quite easily and new flowers will reappear in the same location for many years. They have flowers that can be blue, white or pink in color, and can bloom during spring, summer or fall, depending on the species. Forget-me-not flowers are easy to grow and can usually be neglected for weeks without taking any real damage.
Plant forget-me-not flowers in a location that receives partial shade during the afternoon when temperatures are high. Ensure the soil is well-drained and fertile, and does not hold any standing water after heavy rains.
Sow forget-me-not seeds three weeks before the final frost of winter. Plant the seeds about one inch deep in the soil, as the seeds need darkness to germinate. Allow about five inches between each seed to allow room for growth. Water once per week until the sprouts emerge from the ground.
Keep the soil consistently moist during spring, summer and fall by watering twice per week, but only in weeks with no rainfall. Forget-me-not flowers tolerate moist soil, but excessive dampness may cause root rot.
Fertilize forget-me-not flowers during mid-summer using a balanced 10-10-10 NPK fertilizer. Water thoroughly before and after applying to prevent root or leaf burn. Follow the instructions on the package for proper dosage.
Spread a one-inch layer of pine needles over the soil surrounding forget-me-not flowers after they have emerged from the soil to conserve moisture and stunt the growth of weeds. Remove the mulch during winter, and apply once again in late spring after the new plants have sprouted.
