"Yes"- full credit is due, for all Trudi's hard ground work on the subject, she is a true Pioneer of the art,
I also find her winter sowing methods is very useful in coaxing old hard to germinate seeds out of their dormancy too, as some old seeds just will not respond to high temp treatment, and the slow natural wake up period of winter sowing seems to do the trick in many cases.
