So far is a trial and error when I try new varieties I hill them to see if they are determinate or indeterminate.

I would just love to see pictures of this type of potato. The Seattle Times (?) babbles about this but never any pictures. There is not one truly meaningful picture on the internet of vertical stem producing potatoes. Several shots of carpentering skills building boxes exist, usually plagiarized from one original.
If tubers form a large distance from the seed potato, it is a sign of lack of moisture where and when required. New tubers should form within about a foot or slightly more diameter centred on the seed potato, and always slightly above, hence the requirement for hilling or covering.
