My deer won't touch the stuff while it's growing so it gets to establish itself without interference from browse pressure. You can even taste the bitterness yourself in the leaves of the plants before they are "frost cured". One a freeze or two hits 'em they will sweeten up to almost a salad-like taste.
Ya know, that is what everyone always says, but I've had great luck with deer hammering turnip plot in early October. They just chow down on the darn things!
