Just dig by hand around the base of a plant to see if there are any potatoes forming - if so put the soil back and wait until the plant dies off before harvesting them.

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.

I'm growing just a few purple potatoes in a cage following the instructions above. I've never grown potatoes before at all so need some help please. When they sprouted the little plants are not what I imagined. I thought it would be a tallish, narrow shoot but it is a little clump of leaves about 10 cm round (the clump, not each leaf). Do I just bury this whole thing in the next layer of mulch etc? I can't imagine how it will grow through. Perhaps I should have watched more closely and mounded up before the leaves opened, but I didn't notice until they were like this (the leaves are almost the same colour as the compost mix). So, is it OK to bury them now, or should I have done it sooner? I only planted four bits and the first two are as described but the other two are just coming up now, so not too late for those perhaps but they are all together.
