I "met" Trudi on GardenWeb in 2006 as she was just beginning her "Wintersowing career". She headed up the wintersowing forum for a number of years until she struck out on her own, with the Wintersown Foundation and her website and all of her efforts have paid off.
Anyone new to wintersowing should at least visit her website, and check out the various lists as to when to WS any kind of seed. Her research is ongoing and anyone would gain knowledge from visiting her site.
I have to edit this as her website is down for the moment. I will try to contact her and see what is up.
The best thing for now is to check the winter-sowing forums here on this website.
