20 F is low! If I thought i could get them through winter I'd be tempted to plant em now.
A guy I used to work for told me he kept carrots in the garden all winter, by covering with a really deep straw mulch. But of course they were already full grown.
Another guy I met who runs one of the dollar stores here, told me that he grows carrots in buckets all year round. Pretty sure he meant indoors though.
But it sure sounds copacetic for Texas.
Short winter is a good thing.
