Chufas are great to plant in the spring here, unless you're in an area known to hold some hogs, then it's a horrible idea b/c hogs will destroy it, plus it's expensive. I always have excellent results planting wheat, oats, rye, and crimson clover in the fall. It's relatively cheap, deer love it in the fall, and turkeys will be all over it come opening day in March. When it starts to grow pretty tall, mow MOST of it down to knock the seeds down and give them a place to strut and feed. Turkeys gotta have open areas that are easy to walk in, and they like to be able to see a long way, while leaving some of that tall grass will give more cover for nesting hens. As far as planting in February before the season comes in, I've never done that so I don't know what you could plant. I'll post a link to a website that can answer that though, you'll like it. If you can't plant before the season, just disk up some bare ground and drag it like you were planning to plant something. Turkeys love bare dirt for dusting and feeding on bugs. Go to nwtf.org and read about turkey habitat, you'll learn what turkeys need to thrive. And check out the website below, wildlife planting guide for the southeast. Good luck bud
