Here are my All Blue potatoes just a couple of weeks or so after they got above ground.
This pot is a 24 inch pot with 2 very small seed potatoes in it. Clearly one of them has sprouted 3 new plants. The rest of my potatoes are in deep 18 inch pots, with 1 big or 2 small potatoes in them.
They are only filled a bit, leaving about a foot of space for me to fill in dirt for the potatoes. My plan is to fill them in as they grow and then use rigid plastic to fill in higher than the top of the pot for max potatoes per pot.
So my question is: Do you thin them when you get more sprouts like this? I can't imagine there is a lot of room for growing nice big juicy potatoes with 4 vines in this pot, 2 yes but more?
What do you think?
