Your friendly local spud farmer does in fact add extra earth up the stem to encourage tubers to form on stolons, as the potato stem grows upwards .My veggies are coming on well, ok most of them, but good news all the same.
But I have a query for our resident expert.
I grow my spuds in big pots, and all the advice I can find is to plant them in a few inches of soil at the bottom, let them grow, once they get a few inches above ground level, add some more soil and repeat until you get to the top. Been doing it that way for a few years now, and we get spuds, but I'm all for avoiding extra work if I can.
Now, I've never seen the farmer that grows spuds in the field behind my house going around and adding extra soil as his plants grow, so I want to know if it's really neccessary when you grow in pots. Couldn't I just fill the pot to start with and whack a spud in it?
@mudsticks any chance of some free advice, or from any of our spud experts of course.

If you start them too deep, in your pot or in the field, the initial shoots will run out of steam before it reaches the light to replenish their energy through photosynthesis via the leaves .
It's called 'earthing up'
And is done with a ridger once the potatoes show green tops a few weeks after planting.
Potatoes are planted in the bottom of a trench, then the ridger goes through so the potatoes end up growing in the ridge.
So you're doing it all right, and that bit of extra work is necessary 👍🏼
