Yes this is normal. They are not edible, so pick them off to encourage the plant to dedicate it's energy into producing tubers.

Di - did you ever grow any New Jersey potatoes? I'm in Sydney and I'd love to try and grow some. Thanks so much.

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?

We live on the NSW south coast. As we are new to gardening, the question is, Can we produce a year around crop of potatoes? If so, which varieties do you plant when?

You should be able to grow almost any variety of spuds all year so long as you don't have frosts.

Hi, I'm in country Southern Tasmania and have never grown potatoes before. Does anyone know whether the plants need to be fenced off from the wildlife? (Here we have mostly possums and paddemelons.) Thanks!

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.
