Do you cover up the green leaves with soil as well as they shoot through or just pile up the soil around the leaves and have the leaves themselves uncovered?

Is it too cold to grow potatoes @350m above sea level on Mt Taranaki

Should be ok - as long as you harvest before next winter's frosts. Plenty of sun.

I grew potatoes this year for the first time. I planted 12 pots and all I got back was about nine or ten potatoes. I planted mustard over the winter, dug in etc. it was very dry and I didn't water much could this be the problem. I thought if I watered too much they might rot. What did I do wrong? Thanks

Have good loose soil, not too rich in N. Dig a furrow 12 (?)

I've had that happen a couple of times in containers - it seems they like warm conditions but cool roots or they just produce leaf growth. And yes plenty of water - about an inch a week. Soil should be sticky.

Teashy, potatoes often resprout after a shock like that, have faith, and they could be okay. In my climate, they often get frosted off completely, but then come back from the dead. Mary, potatoes have a really hard time in the tropics/sub tropics. I think there will be some years when there is just too much against them. This year seems to be a bit hotter than normal, so maybe they have a few too many bugs this year, combined with the unusual heat, it could just be a year to concentrate on other crops. If you plant them in the shade, they will do a lot better. It isn't too late to plant some fresh ones, and don't put them in direct sunlight. They are quite tenacious, and will grow in quite low light. The reason they didn't develop more taters is, as you rightly point out, that they just didn't have the time to grow to their full potential.
