Hi, Lou---no darned idea on when to start the annuals. I was going to ask you the same question LOL. This is my first time winter sowing. So far, the only things I've done are some perennials and plants the specifically state they have a long stratification period. I think we have to be quite a bit warmer before we start annuals....maybe in April? (just a guess). I've read the wintersown.org site, but still don't know for sure.
Steven--thank you for the excellent instructions. Can't wait to try the ziploc bag method for my annuals.
