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.

Sorry for the late post -- I think I have the information you are looking for. First NOT ALL potatoes are suited for "tower" growth. So the first question would be how deep are your bags; if the bags are deep enough to be considered a tower, then you need to cross check this with the variety of potato you are growing. Second: when you plant a piece of potato (seed potato) this is your LOWEST POINT. Generally, a potato plant will not produce/store and tubers (potatoes) BELOW the level of the seed potato. This is why people plant the seed potatoes, wait for the green leaves to come up, and mound soil, always leaving enough leaves sticking out to collect light. You'll also note at harvest, that the lowest potato seems to have rotted; this was your seed potato that grew the plant. We plant the seed potato shallow, so the leaves get to the sun sooner/easier and start collecting light; then we mound the soil so there is room for the potato plant to set its tubers (potatoes) -- this means, that you plant you seed potatoes at the bottom of the sack, covering them with several inches of soil, and as the potato plant grows, you add soil.... always try to leave plenty of leaves sticking out of the soil so the plant can collect sun. Hope this help. From the Eagle Creek site (about their tower potato mix): Not all types of potatoes are suited for container growing, typically fingerling and late season varieties yield best. Bellanita, Bintje, Amarosa & German Butterball are the 4 varieties in this package.
