I have just harvested a crop of yellow/orange yams.Can any-one tell me how best to keep the small one's that we use as seed for the next crop as we live in Tasmania and we are coming into the cold months and we get temps in the minus's. Thanks Dave

Hi just purchased a kilo of yummy yams from the Aproneers in Hobart. I hope I can restrain myself from eating them all and perhaps plant a couple. :-). So happy to see them in a shop! Having a kiwi week just purchased a box of feijoas and now yams- all I need now is some Hokey Pokey ice cream....
