Seed starting dates for my particular situation:
Last Frost - April 25
Plant out cool flower transplants and direct sow cool flowers - Mid March
Start Cool Flowers that have a long DTM (Days To Maturity can be found on the seed packet) - Early Feb
Start Cool Flowers with a short DTM - Mid Feb
Start tender annuals with a long DTM - Mid March
Start tender annuals with a short DTM - End of March/early April
These are the exact dates I use, and they are particular to my last frost date. After 7 years of growing cut flower, I do not vary much from these dates. I offer them as an example and not a rule. As always, do what is best for you in accordance with your last frost date.
