I also started wsing in January the first year. Now I agree, March is plenty early enough, even for stuff needing a cold snap. I do have some seeds that need about 6-8 weeks to germinate after being potted up so might start them a little earlier.
Yup you weather may even beat outs. Winter sets in about the end of October and snow isn't gone til first part of April (except for little spots behind or under something. Some early flowers are blooming especially the evergreens like aubreita (sp) and arabis. I think the arabis is the first to be covered in tons of little white flowers. Give them a haircut when they are done and they rebloom in the fall. Wish I had some that were a color. I think mine is called Snowcap.
