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.

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.

This is my second year at growing potatoes near Kalgoorlie. Although it gets hot quickly as long as you keep the water up to them they seem to thrive. All I added last year was some blood and bone and a bit of hay for mounding them up. I've got heavy red loam ground here and the first year I grew enormous potatoes but many were derformed from the rocks in the ground. This year I decided to build a raised bed and use a mix of the red loam, potting compost and hay. I didnt plant till late September because of late frosts but already plants are really high and flowering. Unfortunately I didnt keep up with mounding them up as quickly as I should have and maybe they will not produce as many spuds because of this. I have read that you have to keep mounding them so that only one inch of stem is out of the ground. If the main stem becomes too long and exposed to the sun it no longer grows side shoots and spuds - is this true?
