The seedlings should be hardened off before moving to the garden bed in this small container and this can take 2 weeks.When true leaves have developed, the last spring frost has passed, and night temperatures are 50 to 55☏ consistently, transplant outside into a slightly larger container.Best to cut, do not pull seedlings out as this will disrupt the rest of the seedlings.

Cut the weakest seedlings with nail or manicure scissors at the base. Thin the seedlings, which is to reduce the number in order to create space for the rest.As the seedling grows, can water or mist less often because the roots have formed and are able to obtain water from a lower depth in the mix.As the seed germinates and grow, may have to adjust lights to continue to be only a few inches away from the plant.It is important that they do not dry out when they begin the germination process because germination will stop if allowed to dry and the seeds cannot be “revived.” Mist with water frequently so seeds do not dry out.They should be only a few inches away from the plant. Place under grow lights or fluorescent tubes, leaving lights on for 14 to 16 hours per day.Insert seeds but do not cover, press lightly to make contact with moist soil. In clean seed starting trays (with drainage holes), add moistened seed starting mix.Save the seed and next year start indoors about 4-6 weeks before the last spring frost.After a few weeks shake the bag to release the seeds from the flowers.When flowers are past their prime, cut the flower heads and place in a paper bag.
