Hi potato growers! i have been married for 18 years, and all that time i have searched for Red Dakota seed potatoes. i see a few people on here mention them. cant get them up north here. my elderly husband grew them for many years, and i would really love to grow them too. i grow Maori, red deseri, Concord, Dragar, and a few others. i have saved my own seed for nearly 25 years. and would love to grow this special red dakota, which he says are different from other spuds. thand in advance. i would be keen to deposit a few $ in exchange for just 3 or 4 seed in good condition. please be sure of your variety

Hi - I believe Red Dakota is now on the u/a list. The last I ever bought/ate was in the 1980s, near Blenheim. A well-established market gardening family grew R-Ds, and I was forewarned by the senior man that they would be possibly the last I would get, as they were moving to more popular cultivars. R-Ds were notoriously difficult to clean properly for baking - all those craters - and peeling was a challenge, but they were ideal for roasting.

Go on the internet and do some research. Look for small and large potato seed selling companies. I just looked at Morton Smith-Dawe but they don't have them, ring them and ask if they know of anyone growing them. Or ring the Potatoes New Zealand and ask.

It says to grow in the spring here. Also says that for sub- tropical Queensland Australia. They grow potatoes from April/May here. Give it a try then.

Can I plant seeded potatoes the week after Christmas for a winter crop? And also if yes what seed potato would be the best? We live in north Canterbury

First decide whether you are temperate or cool/mountain - look in the climate zone section. Then read up about the planting times. Then you decide what potatoes you are going to plant. That will depend on what is available in your area.

Have a look at this site www.gardeningknowhow.com/edible/vegetables/potato/determinate-indeterminate-potatoes.htm Or do an online search - lots of articles available.

Do you cover up the green leaves with soil as well as they shoot through or just pile up the soil around the leaves and have the leaves themselves uncovered?

I live in Southern California Zone 10A and grow potatoes year-round in bags and containers, anywhere from 5 to 15 gallons size. I have found what works well for me is to put about 4-6 inches of good soil in the container, lay a few seed potatoes on top so the slips are pointed up, about 12 inches apart, then cover them with about 4-6 inches of soil, and water moderately or they will rot. These potatoes will only produce new tubers in the soil about 6-12 inches above the original seed potatoes, so when the plants are about a foot above the soil, if I have any new add seed potatoes and the container has enough room, when I add more soil I may consider adding a few more seed potatoes that will produce "baby potatoes" above the older tubers, then cover them with another 6 inches of soil that will also bury more of the new growth of the first seed potatoes. Doing this stimulates more growth, and I may even add even more soil as the plants get taller depending on the depth of the container. I don't always add the second layer of seed potatoes, but doing this produces a few larger potatoes below (Baked Potatoes!) and a lot of smaller potatoes above them, and they are all excellent eating. I am growing Russet, Golden, and Red potatoes in containers, but I think they are all determinant varieties since they are all started from potatoes purchased in grocery stores, and each plant only produces tubers in the area near the seed potato, but do not continue to produce tubers as the plants get taller no matter how much more soil is added. I am still learning as I go, such as "location, location, location!" is making a noticeable difference on how successful my efforts are, and I would like to find an indeterminant variety potato that will grow well in Zone 10A.
