Thanks again!!! You’ve been very helpful!!! I’ll get planting soon!!I would guess the first the are determinate as they have short harvest times. The "white" may be indeterminate based on its longer harvest time, which is more common in indeterminate I believe.
But again, it doesn't hurt to hill or tower them. Another thing, if you use a container of any sort, be sure it's about 18" wide or more. The potatoes firm up to a foot away from the seed potato. 18" gives up to 9" from center which isn't too bad, but I wouldn't go less. Also ensure you have drainage of course. Potatoes don't like to sit in soggy soil.
Lastly, get those seed potatoes in soil soon. They are putting energy into those shoots you see growing in the last pic. Trim those to just about 2-3 inches with sharp scissors before planting (whether you decide to segment the potatoes or not).
Best of luck! I hope to plant my potatoes soon. I will take pics when I do.

I think I actually have the perfect spot for them. We have a hill that’s pretty sunny and it’s also somewhat sandy or at least more so than the rest of the yard so good drainage especially being a hill. Not great for a lot of other stuff but I think it would be perfect for the potatoes!!
