Winter potatoes

[VioletDove]

Howdy all you green thumbs!
  I would like to try a Fall crop of potatoes this year. I think I will have a much better chance during our super mild winter than battling the intense heat and insects we deal with (Tx)
   So.. I've never done these and would love any advice you guys might have.  Is it too late for me to get a bag of organic potatoes and let them sit until mid or end of September and then plant?  I just don't know how long they need to 'rest' or do I even need to do that? Can I go ahead and plant them straightaway once we get under 100°+? 
 I've heard russets don't do very well here but yukons and reds seem to be a pretty good bet so I'm gonna try those I guess. 
Any advice/comments appreciated!

Not sure if I’m much help as this is the first year I’m trying fall potatoes. We had some left over from our spring planting that had already begun to sprout. I planted mostly reds. 

We also bought organic ones, cut them and planted them to see what may happen with them. We made some wire cages and put straw and a little dirt in there and layered them. We had good luck doing it this way during our spring planting. Our ground here is too rocky and hard so this worked a lot better.

Good luck with your potatoes.
