Hi June. I plant a sweet potatoe around August or September and let it grow wild. Then I take cuttings from that about 3weeks before Christmas and plant them out ,making sure I water them in really well for the first week or so. Then I harvest them just after the first frost with pretty good success.

I live on the Sunshine Coast Qld and I am trying to source runners or tubers of the NZ Kumara, if anyone has some available I’m willing to purchase, the Aussie sweet potato is so so different.
