When best to plant potatoes in Turangi - still pretty cold down here at moment - do I wait until September or maybe later?

the issues to consider are: Do you have chitted seed? When is last frost date? When does the psyllid bug become active (usually around December) Even if you plant now they will just sit until conditions are good. You can make earthed up rows and plant into that rather than in cold hard soil.

Where can I buy any English Variety "New Potatoes" for planting in our Home Garden. Any ideas would be very much appreciated. Many thanks. Stephen

How best can I use, an old bag of coffee grinds in the garden.

We had tomato and capsicum plants that were growing really nicely and promising in big pots with organic potting soil, compost and fertiliser. When we heard about coffee grounds and applied them, it really set these plants back (visibly evidenced) and they did not fruit much at all. They were our pride and joy. There are new articles on the Net about coffee grounds Not being a good idea close to our plants - there maybe a few exceptions. We would never take the risk again.

Just spread it out thinly in the garden and mix into the soil. Or use it in your compost if you are making it.

It is more about what variety you want to eat. Five people will probably tell you 5 different varieties.

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.
