Six to eight weeks before the transplanting date, sow the seeds according to packet directions into a container indoors or in a cold frame, greenhouse, or other protected growing structure.
Seeds. A greater variety of seeds are available than transplants, and seeds are less expensive. Some seeds can be sown directly into the garden. Plant seeds according to package directions. You can also grow your own transplants by planting seeds. Six to eight weeks before the transplanting date, sow the seeds according to packet directions into a container indoors or in a cold frame, greenhouse, or other protected growing structure. Gradually transition seedlings from the protected environment to the garden, hardening them off by slowly introducing the transplants into full sun for a longer period each day over a week’s time.
