Hi John, i'm another Kiwi called John and really stressing for proper kumara, i don't like this sweet potato here it isn't even close to proper kumara, did you manage to get hold of any plants at all, i live in Park Ridge South not far from you at all, like to get in touch with you, thanks mate.

i have a crop of kumara growing from some i purchased in Woolworths (though not seen often, but they have some at present) I cut the top off one, let it dry a bit and then put in small amount of water, grew several runners, which i then planted out. I did put some sand in the garden bed though, as I always remember my dad telling me the Maori used to grow their kumara in the sandhills. Seems to have worked well.

Hi John, I have been growing Kumara in loganholme very successfully and can assist you with runners. Once you have growen them you can keep growing them from your own runners. If you would like to pick some up just give me an email

Hello Martin, Is your kumera the NZ variety - lemon flesh streaked with purple? The taste is nothing like sweet potato we have in Australia. If so I would dearly love to have some of yours! I'm very happy to pay! ! I'm in Maleny. Susan

Hi Martin, would you be able to supply some runners via post to WA? (at our expense) would love to grow some NZ Kumara here! Thanks :)

Nins Ricci, saw your comment in early june and wondered if you are in the Brisbane area. I am going North soon and would love to buy some pieces or cuttings of the NZ Kumera. I am in Brisbane and wasn't going to plant till late August. You mention the plant is still growing crazy. Did you harvest any yet? I am wondering if it is too cold at night in Brisbane to plant some yellow ones now.? If anyone else would like to reply, please do so. Thanks

I bought my "seed" tuber as a vegetable in the supermarket. Some gardening experts say to wait until leaves yellow & plants die back before harvesting. I am in Townsville and that did not work. Plants grew 12 months a year. Tubers were bigger than footballs, woody and had insect attack and rot. Suggest you follow other advise that recommends harvest in 16 weeks. Tubers are smaller and tender.

The orange sweet potato/kumara can grow like a weed. I recently dug up a patch and for months tiny kumara plants were sprouting. Some from the smallest pieces of broken root. If you see one you like in the supermarket, I suggest you chop some up and plant it. To harvest, they poke out of the ground when ready. Feel around for a big one, then remove it by hand. Be careful not to break it in two.

Bunnings sells the kumara plant in QLD along with feijoa trees which were both thought to be a NZ thing only? Or you can get on eBay though there are certain restrictions with sending fruit or plant matter between states.
