I happen to have had a potato that was REALLY going to town in the bottom of the bag, I'm sure it's not a odd thing to happen in a kitchen when a tuber has had plenty of time to sit in storage waiting for the rest of the 10 lb bag to be used. Now I have NEVER grown potatoes before and really am excited at the idea of experimenting with them so I thought what the heck. If they die then lesson one learned if they live.... cool! so I cut the tuber into 6 pieces set it out on the counter to scab over and then promptly tossed the suckers in the ground every witch way because I couldn't figure out how they were going to come up. Any way's all 6 are now about 2 inches tall robust looking little tater plants. So heres my question, why do I get one answer then the other depending on who I talk to? One person will say SURE it's perfectly fine ti use those old sprouted taters to start your plants and another site will say NEVER use store bought potatoes they have desiease and are coated with chemicals and it just won't do. So I was curious what's the real story behind all this? My plants seem to be doing marvelously.
