I live in Melbourne and a ex Kiwi. Can you tell me please if one is able to but the NZ kumaras here?

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.

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 live in the Hunter Valley and the major supermarkets stock gold swt potato all the time.I believe they grow like regular potatos, so try buying some and store them in the cupbaord until they shoot.

They don't grow like regular potatoes and some of our customers have suggested they have harvested up to 40kg off the one tuber. Good stuff.

Bob, I had the same problem so I ordered a couple of sweet potato's from Walmart. I tried to grow them on my counter to no avail. I went on YouTube and found out that stores buy potato's that have been sprayed to prevent sprouts. Best if you buy your potatoes from a farmers market. Wash them, then cut them in half. Plant the half's in a good compost and keep moist. You should see slips growing out of your potatoes in a few weeks. I found it time consuming but it works! Best of luck to you.
