IT’S MY FAVORITE HARVEST MOMENT OF ALL: The garlic is in, and the barn smells like it. Seventy-five big, fat heads of ‘German Extra Hardy,’ a hardneck variety also sold as ‘German Stiffneck’ and beloved by Northeast growers in particular, are up and out and under cover. Want to grow garlic for year-round use? Some links below may help, and remember: Save the biggest cloves from the biggest heads you harvest as your “seed” for fall replanting. Such methodical selection over time will yield a strain as zaftig as mine, above. A dairy farmer wouldn’t breed from his weakest cow, now, would he?
