Ok. I planted some fingerling potatoes about a month ago. Here’s what I did. I put them in in a bright spot (but not direct sun) for several days. Then I looked for the eyes. Many fingerlings won’t have more than 2 or 3 eyes per potato. Need at least 2 on each seed piece. On potatoes that have 4 or more eyes try to divide them up as evenly as possibly wrt the eyes leaving as big a chunk of ‘potato’ with each set of eyes as you can. Next I took a dinner plate, put several layers of paper towels on it, and then put the cut potatoes on the plate and back in the bright spot for 2 or 3 days. Then Planted them just like regular potato planting.
As of right now I have pretty close to 100% germination from the pieces I planted. These weren’t ‘seed’ potatoes either but some I got at Kroger. YMMV.
These Fingerlings are small so I’m planting the whole potato. A bright spot would be right where the upper deck meets with the lower deck as that gets bright with a little sun in the morning but the shade from the lower deck roof puts shade over that place fairly quickly.
The are in a heavy duty blue plastic net sack so I’ll spread them out in there and leave them in the net so no killer could get to them. I copied what you said. Thanks.
