Hi! Just created new vege garden at new house on Macleay Island, Qld. Another kiwi dying for a feed of yams. Where can I get tubers please?

Hi John, I planted those yams you sent. They suffered a bit in spring with weeks of +30 heat, but have taken off now the temperature is more 'normal'.

John, Any chance of getting any yams? I know its a little late, but I am willing to try anything. Usually I half cook, and then freeze them to bring them back to Sydney, but if only I could get some fresh ones, that would be amazing. Linda

Hi John, I have been trying to get hold of some Oca tubers to plant this year and have not found a source in Tassie as yet-the closest i got was Young's veggie shed in Nthern Tas, sometimes they get them in from a local grower. Any chance that i can buy some off you? Cheers Steve
