Interesting that you guys are having trouble with deer eating your sunflowers. I plant an acre of sunflower most years, in a place that is
overrun by the dang giant rats. Could be there's plenty of other stuff here that they like better, because they've never done any noticeable
damage to my sunflower planting.
Neighbor up the road has two patches of native wildflowers on his property, both ~1 acre. He burns them off in the spring to keep the
fescue from taking over. That is working well for attracting quail. He generally has four or five covey on his 20 acres.
