HI Nial It depends on the variety. You can get 'early' or 'main' crops. Early varieties take about 90 days from planting to harvest, although I find I can get a good crop in just 60 days, but I am in Auckland so the temp may help. Main crops can be 120-190 days depending on the variety. If you do a google search on seed potato varieties, there are some nz websites that have tables showing the different types and how long they take to grow. Steph

Hi. Do you ever grow 'early' potatoes late? ie just use them whenever you would like a quick crop of potatoes? And what is your favourite for flavour? I'm growing Arran Banner now. I just got a community garden plot in December and I found a bag for peanuts. They are doing well, planted mid December, but they are forming flowers already. Cheers

Hi guys, i am giving potatoes a shot for the first time, but have no idea how to tell when to harvest! any advice would be great, thanks! (sorry if this has already been asked)

Hi Lisa, yes the actual potato is green if it has been subject to light so you should keep the plants well mulched in case the potatoes are close to the surface, my spuds are still showing no signs of shooting, they are in the potting shed in egg cartons, will they shoot soon? Or shall I just plant them now? They are certified seed spuds.

i have planted potatoes about 3-4 weeks ago (i didnt bury them as i have very hard soil here) and have been covering them over as they shoot. how long do you have to do this as i keep getting told from people there should be no need to cover them over as they grow. also the poisonous thing is a bit scary - how do you know if the potato is green? is the actual potato that you dig up a green colour?? thanks, L

I am so confused about how to sprout seed potatoes. My local nursery says keep them in the cool and dark but a reputable gardening writer spent a page saying keep them in the warmth and light. My Ruby Lou's have only about 1/2cm of growth after almost 2 months. Please help!!!

I notice people have already planted potato tubers? Am I too late?

Thank you for telling me all about growing potatoes. At school our project is to grow potatoes independently. Thank you, your web site has helped.

Thanks Emma. Yes I know about green potatoes being poisonous that's why I was worried about planting them but I think, like you, that the new ones should be okay. No shoots appearing yet though, still a bit early to plant here.
