When we have a big supply, how do you cure? And keep them. ? I have found they just rot when we dig them up

Don't water them for the last 2 weeks or so before digging them up - toughen them up a bit.. Put them out in the sun or shaded area for a week or two to get a tough skin. Then in a cool dry place. They should keep for few months.

When do I plant the slips sweet potatoes? In my zone. We have been having late frost as late as March the past couple of years

There is no planting guide for your climate zone in the USA. Your climate doesn't suit by the sound of it.

I want to try and grow nz Kumara / sweet potato I live in Ararat Victoria. And where can I buy slips please. Thanks

Plant a couple of sweet potatoes and use the slips from them. Use the new vine part. Strip most of the leaves off a 250-300mm piece. Did trench and lay flat with the growing tip out of the ground. Water a lot the first 2 weeks. That is the way commercial growers plant sweet potato in Qld

Can you plant an whole kumera in a container and get a crop?
14 Sep 20, Anonymous (Australia - cool/mountain climate)
Yes you can but you don't need a whole kumera, a piece of vine will do. A piece about 30-60cm long of the new vine growth. Place in a trench with the tip sticking out of the soil, water twice a day for the first 2-3 weeks.

Or depending on how big the spud is, cut it into several pieces and let them dry in the sun for a few days then plant them.
