I live in Zone 10A and have been growing russet and golden potatoes in grow bags and large containers here for about three years, and I notice I can plant them year-round and they will grow, just slower in winter, and if we get an occasional frost, it may kill the top, and when temps hit around 100 or hotter the potato tops may die off also. No matter what time of year, my potatoes often grow for a few months and then the tops start to die off no matter the season or conditions, but I don't know why, so when that happens, I'll reduce the watering for a couple weeks and then harvest. I try to do "succession" planting, so I always have some potatoes growing, and am still experimenting with what works best, especially trying to learn more about correct watering for the Zone 10A conditions. I do have better success, producing more and larger potatoes, with 10-20 gallon and larger containers than the 7-gallon fabric grow bags.

Check the planting times for your zone.

I have had some sprouting potatoes given to me. Can I plant them now? If not, will they keep to August?
02 May 22, (Australia - temperate climate)
Yes plant them now.

Hi, can you advise on a first early potato to plant. I can only seem to find mid or late varieties when I goggle. Thanks. I am moving to NSW Bega valley area in June.

Your planting guide is Aug to Oct so I don't really see the point in an early variety. Planting is about soil temperature and after the likelyhood of frosts.

I have to say that potatoes also grow amazingly well with parsley. They seem to be great companions.

They also taste amazing with parsley garlic and butter.

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.
