Gotta ask you your definition of "in the woods"? Around my land there is nothing but woods, 100's of thousands of acres of woods, savannah grasses, and forested flood plains. When I put in my fields and plant my roads, isn't that "in the woods"? Certainly, in farming country, where most acreage is planted in corn, alfalfa, wheat, oats, etc. plantings in the sparce hard timber stands that remain would qualify.
Another difference here is our trees don't shed bare, hince plots are not lost to dropped foliage covering, unless of course you account for palm tree and palmetto leaves occasionally dying and dropping into the plot. That would be a "local" die-off of the plantings I suppose. There is no real distinct season of Fall in East Central Florida. Sure the days get shorter and cold weather and drier air conditions occur, but we're closer to the tropics and that has a lot to do with it.
I started planting Fall plots in July with glyphosate herbicide, bush hogging, discing, glyphosate, glyphosate, glyphosate, fertilizer, discing, glyphosate, seeding, chain link drag over new seed, and prayer for a light continuous wetting rainfall (received with Thanks). I had an infestation of air potato
http://edis.ifas.ufl.edu/AG112 and killed over 99.44% by burning it chemically to death. "Now class, how do you think that felt?" (Mortisha Addams, The Addams Family). By mid August I was planted. By mid October the deer were all over the iron and clay peas, the sorghum had sprouted beyond my wildest imagination, and the poor pitiful white clover got choked out in most of the plots.
How is it a small dormant seed like clover doesn't germinate at all whereas a small weed seed like Johnson grass does. Both were planted in the same location (one on purpose by man the other through dispersal by God) and none of the man's clover came up. I don't get it. Did the clover germinate and die? Is it still out there dormant in the soil? I want my $10.00 back! Just kidding...
