I'm hoping to encourage people to offer more information in their posts, if they possibly can. Instead of saying "we grow lots of things under conditions x" can you please list out some or all of the things you grow under conditions x? It would provide much more helpful information than all the wondering or repeated questioning that some of us (at least me!) are currently laboring under. It's all old hat to you but not all of us know everything - or much at all!
Just put the cards in their christmas stocking and PRESTO! They get it now! It's like you're the harry potter of permaculture. richsoil.com/cards
