Bird,
I live in South Central Indiana. I hunt in Lawrence, Monroe, and Green Counties mainly. I have seen just a handful of plants starting to turn yellow, but my concern is what is this heat going to do two or three weeks from now. The berries on plants seem to be very fragile right now. When I was out scouting, I moved a plant to get a better look at it, and most of the berries just fell to the ground. I'm being very cautious right now.
