I had some good potato berries this year.
So I decided to try my hand I growing potatoes from true seed.
I let the berries ripen for a few months then I ground them up in a blender then let the pulp and water ferment for a week or so. I then poured off the scum and washed the seeds with trisodium phosphate to remove the germination inhibitors followed by a wash in 1:5 bleach solution and a hot water rinse. I then dried them.
I planted them in a warm place, 85 degrees is best.
13 days later I have my first sprouts are coming up. The mother plants were Augusta and Purple Viking so I am hopeful that these are something interesting.
