I'm new here, and have nothing to contribute (never mind there's still snow on the ground and my zone doesn't call for much quite yet--plus the path to the greenhouse is icy!) but I wanted to say 'THANK YOU' for the thread and all the ideas...and especially the enthusiasm and experiences that come through.
My "beginnings" (I haven't gardened in decades) are in an Excel spreadsheet, so, "mnmat", your samples are terrific to pore over.
Thanks to everyone,
Cynthia
