Where can I buy seed potatoes, please. We are in the Lockyer valley. Last year we grew sebago and had a wonderful crop but can’t find any at the moment,

Try some produce agency (supplies to farmers of farming stuff), then a nursery or on line.

If I plant my potatoes now, do I keep them in my unheated garage which gets a bit of light or put them outside where we are still getting below 0 temperatures?

Potatoes can go in the ground now -- the cold temperatures won't do anything to them. In fall when I harvest my potatoes I tend to miss a few (those little tiny ones) -- and they are in the garden all winter (sometimes temps drop as low as -10c) and they still grow. Generally speaking, potatoes can be planted as soon as the ground can be worked. Don't forget to add lots of potassium (also called potash) to the soil.... potatoes LOVE potassium.

I'm planting potatoes in root bags. When should I plant (indoor) and when can they be left outside?

I made sectional container and added 7" sections as growth poked through. Got to about 5' tall . when I unveiled it in latter fall there were very few potatoes. A lot of care for no result, any idea what happened?

Neig, the potatoes you planted were probably determinant, which means they will only produce tubers for a limited space even if the green growth continues and you keep burying it as it gets taller. That is what I discovered when I tried to grow in potato bags that are 17" tall, 13" in diameter. I used store bought potatoes and used any that started sprouting as seed potatoes, and began with 6" of soil, put seed potatoes on top, added another 6" of soil, and when the tops got about 8" above the soil, I kept added soil as they grew, thinking the plant would produce more tubers above the original layer, but none have ever done so, so I think all my russet, golden, and red potatoes originally purchased from stores are all determinant varieties. If anyone knows of any indeterminant varieties suitable for container gardening in Zone 10A, please post.

I live in Taree, Mid North Coast, NSW. I have Potato Bags ready for planting and would like to know when is the right time for me to plant. Also, when do potato seedlings go on sale. Thank you.
