Hi John. My partner loves yams. I'm not such a big fan, but would love to purchase some for him. We would like to grow our own as well. I would really appreciate it if you could help us. Many thanks.

I would love to grow those gorgeous little pink yams that we could always buy in N.Z. Not the huge sweet potatoes we get here in Oz - the yams I'm after are about the size of an average thumb. Anyone know where I can buy seeds or plants in Perth??

I can see are many of us yam-starved NZers in OZ - I have been searching for them for years and have just yesterday purchsed some tubers on ebay. Yippee, now I hope they will grow successfully in SE Qld. Has anyone else had success with them in this area? Comments appreciated. Thanks Janice

Hi Janice - My mum is in Brisbane - I gave her some New Zealand yam last time she was down in Gippsland (my place) and she says they are growing well in Brissy. She keeps them in semi shade in the hottest part of the summer, and makes sure the water is kept up. She had a good yield last year, so I reckon you'd be ok to grow them ( and worth any effort, they are delicious>>>)

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 Dave, I am an ex NZer living in tasmania and haven,t had a good feed of yams in ages.Saw your comment and wondered if you might have some extra yams i could have or know where i could get access to some in tasmania so i could harvest my own Thanks Garth.

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....

My first attempt to cultivate yams has resulted in no tubers at all even though the tops grew well and died down Why did I not get any tubers?????
