I ate kumara everyday when visiting NZ and loved it! Because it was less sweet than USA sweet potatoes. I am craving it and need to find out how and if I can get seeds and grow it in Virginia? Would love your help on this!

I read an artical about Sweet Potato/Kumara that planting in wet weather is not a good idea. It went on, to wait until it drys up a little then plant, about April?

I work for a company which sells sweet potato and the Kumaras you talk about sound like what we call Beauregard orange in flesh and skin.

Has anyone had luck planting kumera/sweet potato (any type) in cool zones? If I protect from frost and wind would it be possible..and where to get the plants (especially purple) ?

What soil conditions best suit the sweet potato, as far as the pH goes? And are they a high yield plant, or do they produce relatively few tubers, requiring a large crop to be planted? I would like a decent crop, as I go through at least a kilo of them a week - sometimes more.

I have had for over one year a half 200 litre plastic drum with a sweet potatoes growing in it. Just this past weekend I have dug around in the totally dry soil looking to see what was there. I did this with my hands after loosening it up with a garden fork all around the side of the drum. The leaves were not dying off in fact new shoots are forming. I only did this as we have had 1 week of dry hot weather. I harvested 3 very good sized spuds and put the rest back and topped up with well mulched soil. No extra fertilizer has been used and this is the second time I have turned this drum. As the soil lowers and parts of tubers show I top up with more well mulch soil. With watering and good old mother nature we have bought no sweet potatoes at all for quite some time. I have no idea how long they have been growing I don't garden like that.
