cutting seed potatoes -- should they look like this?
About 10 days ago I put my potatoes in a single layer, warmish place, with indirect sunlight. I read to do this in the Ronniger's potato catalog. This pre-sprouts them and has a few advantages over immediate planting. So far it's working nicely.
Several days ago I decided to cut the really big ones in half, and then I put them back with the others to heal over and continue pre-sprouting. I'm planning to plant them in a few days.
The surfaces I cut look pretty ugly! They're grey/white and moldy looking, tho I don't feel any mold on them. A few are black. Is this the way cut seed potatoes look, or did something go wrong?
If this isn't normal, do you think if I planted them sooner rather than later, before they get worse, they'd be OK? Or maybe I should recut those areas to remove the blackness?
