potato box inspection

I took a lower board off one of the potato boxes to see whether there were any potatoes. There were plenty of fine roots, but no visible spuds. I didn't dig into the soil to be certain, though. These are late harvest varieties (Desiree and Yellow Finn), so perhaps it's not unexpected that they haven't produced anything yet. I suppose that what's happening at this point, with the vines being continually covered with more dirt as they grow, is that a continuous root system is being built and it's only later that the tubers appear.
