You could throw in some winter rye before the last time you mow it. I seen that work but never had luck with anything else like braisscas taking in established clover.
Looking good!! Great to see someone doing things outside of the box when it comes to food plots. Shows that when done at the right time you can get good results without having to buy that $30,000 tractor with tiller attachment!
It's seems like they're starting to a bit. Some of the plants are noticeably larger, so hopefully it does what you're thinking. I thought about going through it with a hoe and killing some of them out, but I'm not sure it's worth the effort.
Yep easy to overseed. Worth a shot to go in a small area with the hoe and see if it does better then just leaving it alone. Not sure what you did for fertilizer but wouldn't hurt once the plants get above a few inches to broadcast some fertilizer before a rain.
thats always a crapshoot (timing). i usually mow my clover for the last time late August and i also use a riding lawnmower. if a good rain comes right after, it can work well but if it stays dry, i may not grow much before a frost. 50/50
