I'm about 35 miles NE of stxranchman and usually plant about the same times he does. I waited a month, because of the armyworms I was seeing and planted 13 acres of oats on October 18. I saw one worm on my windshield while I was planting and thought "crap".
Everything worked out very well, an incredible stand with a lot of seed on the ground with nice flights of morning and whitewing doves. I even mowed it down to no-till native grass seed into the 13 acres but the oats are back up with the cool temperatures. So far, five months of food.
I don't use my food plots for hunting so I don't face the need to get the plants up. I'm going to wait from now on. I also planted another 5 acres with other seeds and it worked out the same. Post rut buck numbers on my place were absolutely crazy. My focus will be hunting very late December & January based on my experience this year.
