I have two furiously shooting kumara that have been growing in the pantry (!) Whilst I was overseas. I'm located in a very sunny spot in Auckland, is there any point in attempting to grow them now? (End Feb)

Give it a go.

Pop it in the ground, that way you will have slips for next Spring. However, if you get cold winters over there, pop it in a pot, so you can move it to the garage or shed during the cold days and nights.

When is the best time to plant out the new growth from a tubar. I have a sweet potato that has sprung heaps of shoots. I'd like to put them into pots. Will they grow over winter in I keep them warm or am I wasting my time?

I am in Adelaide -Temperate, and I leave mine in the ground over winter.

Put them in the ground if you have a garden. Cover with some shade until they start to establish themselves. Sweet spuds are grown all year round in Bundaberg - 30-35 degrees in summer.

Does growing sweet potato deplete the soil of any particular mineral. I have grown a good crop of the sweet potato & intend to plant some sweet corn on the next full moon. Is there a particular fertiliser that’s advisable to add, prior to or as planting? I understand that all soils are different, but assuming all things are equal, is there something to add?

A bit of fert in the soil now and when the plants are about 12-15

Someone recently told me sweet potatoes take a lot out of the soil - NPK and trace elements etc. A general all round fert should have about 10-14 N 3-10 P and 12-15 K with 1-2 S. You can then up grade to a fert with trace elements. I buy from a farmers fert depot. 25Kg bags cost $20-25 and $30-35 with elements in it. You can buy stuff from supermarkets or Bunnings but you pay 2-4 times the price for smaller 2-5kg bags. Or you can go the organic way with manures et.
