The easiest way is to dig up one plant to see if there are any potatoes .

It does say 15-20 weeks to grow and it does say plant Aug to Dec. Usually the plant tops starts dying off.

I didnt plant potatoes but they shot up from last year's crop. They started in autumn but the frost has now killed them. Why did they shoot at such a strange time and will they reshoot - or should I just harvest the new potatoes that they have produced before the frost killed them? I'm in South Gippsland Vic and we get pretty cold nights this time of year.

Harvest them. Crop time is 15-20 weeks from germination/shooting - consider this when planting and frosts.

I live in Clarence Town NSW. TEMPERATE climate but we do get frosts. I have just bought some seed potatoes. Should I plant them now or wait until August? If I wait, do Ineed to put them in the sun to encourage them to shoot?

Put them in your pantry until late August and then plant.

Most decent nursery's will stock seed potatoes. Failing that, you can buy them online.
