We got a bit tired of all of the digging up and not finding them all. This

stop the millions of potatoes cropping up where they're not meant to next
year.
I always think it's the thorough deep digging looking for spuds every 4
years (4 year rotation) that makes the soil deeply friable. Who needs double
digging when you grow spuds.

I think you're probably right. That and the manure/compost added. But it's
ok, we dug the bags in, so there was still a fair bit of digging put into
it. Plus we riddled the soil into the bag, so there was a lot of spraff and
stones removed during the process.
