Thanks for all the info,
@Gymgirl!
We really don't have issues with frost down here in McAllen--we cover things maybe two or three times per year and the rest of the time we're fine. This year we were having highs in the upper 80s and into the 90s by FEBRUARY, which was probably higher than usual, and our first 100+ degree day came in March.
It seems like I ought to have production going strong in February and March at the latest if I'm going to get anything. Planting should happen roughly in October, I'm guessing. I'll check into the Sioux variety you mentioned, and see if I can get the timing right next fall. If I can get the variety and the timing right, maybe I'll have a chance at battling the stink bugs!
