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.

I bought some moi moi potatoes at the local organic supermarket Huckelberrys in the vege section. I tried planting 5 in a 20 litre and had quite good success. same with yams and kumara.
