Plant different potato varieties together?

I'm getting ready to plant container potatoes and just want to make sure I can plant maybe 3-4 white variety seed pieces and 1-2 red variety seed pieces in the same container. It is about 2 ft wide and 18" tall.



Also, I've read about adding potting mix, etc. to the container as the plant grows (like hilling the potatoes in the field) but the layering confuses me. I see lots of people say to start with ~6 inches of soil under the seed pieces and ~6 inches of leaves or compost above them. I only have potting mix and leaves/pine needles. When I go to build up the next layer, do I just add the potting mix on top of the leaves? Or do I just use more leaves?

But how long is it? Each of the plants will need a foot (and better 2). Mixing won't hurt as they produce vegetatively so cross-breeding is not a problem.
Reply:Yes, mixing them is fine. Add more potting mix as you layer up, not just leaves. Good luck!
Reply:Planting them together is fine. I would mark them with stakes so I know what I'm going to pull. They may have different growing seasons or may be for different purposes like baking or boiling.



Good Growing :)
