The GM issue is GOOD reason to become a gardener if we live in Argentina. Purity of food supply is the only reason I can think of to add all that work when food is so readily available. Uruguay has kept GM out except for soy and corn. Here it appears you almost need to get into gardening, even if it is balcony or rooftop, as far as I can tell. I thought perhaps someone here would know what no one else around here seems to. And yes, Dirtboy, I can tell you know what I'm talking about. I've been surveying my own balcony to decide if it's worth it, even though a phone call will bring anything I want right to my door!
