Hello everyone,
I have been recieving info from this listserv for the past year.  I have some 
questions about growing potates.  I am planning on growing them in old, 
stacked tires. Has any one used this method and was it successful? Also, the 
potatoes seeds are small, when I cut them how long do I have to wait to plant 
them. I was told I needed to wait for them to develop a "skin" otherwise tey 
will rot. Do they need to sprout first?
