I've started WS'ing some things, pretty much plants that I'm pretty confident would self-sow here... This is only my 2nd time of trying this, so I am fairly much in experimental mode! I look on it as plants that would have the instruction to "sow as early as the ground can be worked." In March I'll be doing some things that are a bit more tender... and probably most of the things I winter sow I'll also start a few seeds of under my lights to see how that compares.
