Donna, wintersowing begins on winter solstice, Dec. 21, for all areas. It doesn't matter where you live.
I'm never that organized and efficient. I start with perennials and hardy annuals around January. I don't sow tomatoes until around March. It's officially spring before I sow tender annuals. I haven't done those yet, but I intend to do a few very soon, probably in the next couple of weeks.
