It says Sept to Dec for cool climate. So probably Oct to Jan. If you look up your veg and put in the climate zone it tells you - then adjust it to your conditions.

all my potatoes are growing in the same soil mix sandy loam ,mushroom compost general mulch etc and ive followed your planting tips . Some are doing really well and some are stunted and look a bit sad. The best ones are producing some potatoes but im worried that the others are not going to be much good. Any ideas.?

I tried to keep hilling up with a 1/2 compost mulch and probably soil was too wet. I did get much of a crop. Use good soil with completely composted material. I would say you probably have some disease.

Better to grow them into winter. Plant about May. The hot sun during winter sucks a lot of water out of the plants during the day. You would have to water them 2-3 times a day.

A friend was advising me when I was planting potatoes. He even dug the trench for me. He then told me to put the spuds on the pile of dirt, not in the trench, about a thumb length down. As I'd never planted potatoes before I duly followed his directions. I now read this info only to find that they should have gone in the trench! What now?

If the plants are quite small try transplanting them into the trench. Make sure you keep as much soil around the roots as possible. - like use a shovel and place them in the trench carefully so not to let the soil fall away.

The handbook-which I provided the location to in my prior reply is not very beginner'ish but it is comprehensive covering issues you may never encounter- but you do need the reference material. I have a few thoughts to add. 1. Hilling up while the plant is growing-if you are covering leaves I find this fundamentally wrong. Leaves are specialized and designed to collect light, they are not roots. So I opt to plant my seed potatoes deep enough on day one- however I tend to have the luxury of very well airated, light soil. This means the seed potato has a steady air supply and can sense the heat from the sun even at deeper depths 2. Your seedpotatoes need all their potassium Immediately. Potatoes strangely take up all their potassium that they need really early. -and don't uptake more. If there is not enough potassium in the very early stages your potatoes might have hollow heart (looks like hollow rotting middles). Late application of potassium tends to be useless 3. Potatoes seem to respond really well to the addition of microryzal fungi - in my area we source that under pine trees in a forest- we just take some forest floor duff with a dust pan and add to the potatoe planting soil. To sum up - your seed Potatoes should be about the size of chicken eggs (if larger cut up ensuring an eye on each piece and allow a few days to heal/scab up before planting). You need to chit them(make them sprout-place in dark so they sprout). Plant in soil with Compost, a sorce of potassium and microryzal fungi. If for some reason you cannot source any compost/pottasium/microryzal fungi -plant anyhow potatoes are tough -there is still a good chance they will be Okay -depends on the condition of you soil. In my area I can water deeply once per week. Harvest when about half the leaves have fallen over as if to die. If you harvest sooner you may be compromising on size-because as long as those leaves can collect light they can store the energy in the tubers. Good luck - it is so much easier than it sounds- and all those diseases in the handbook are rare and if the plants are strong (well fed) they can manage just fine, potaoes are pretty tough root crop. In other words- you can grow potatoe.
