I'm interested to see what others are doing.
For my cleanup, I will cut everything back and may leave the root-balls in the soil with the exception of the tomatoes until late winter. If I have any thing that has gone to seed and flowered I leave it be until the first frost. The herbs are left undisturbed. The sunflowers, if spent, are chopped and into the compost heap.
The salvageable veggies are set aside and the ones that can not be saved go in a bucket. All the "healthy" plants with the exception of the tomato plants are chopped up and tossed in the compost bin then I mush up the waste veggies with some water and toss in the compost heap.
The tomato plants are tossed in the fire with some hardwoods. After a few weeks the fire pit is cleaned out and the ashes are divided over the firepit and on top of the beds.
All the veggies will be processed one way or another, sundried tomatoes, tomato powder, eggplant Parmesan, eggplant burgers, dried herbs, stevia sweetener, hot sauces, blanch and freeze, fire roasted peppers that are dehydrated, and my now famous end of the season garden jambalaya. I haven't gotten into canning yet. I'll be asking advice on that soon
In late winter before any planting, intact root-balls are pulled up and the soil is shaken off in place, then the root balls are tossed in the fire.
I found this quite interesting as well;
Cool season plants will continue to grow in cold weather and don't need to be removed right away. Leaving brassica plants like cabbage, kale, broccoli, Brussels sprouts, cauliflower, and radishes is a natural way to kill some insect pests. The vegetation attracts some harmful insects. After harsh winter temperatures finally kill them and the plants begin to decompose in early spring, they'll actually release cyanide compounds that will kill those pests. You can pull them up and add them to the compost pile in spring.
That is how I have been doing it and there are a ton of tips out there that are conflicting, anyhow I found these articles interesting.
Tell me how you do your cleanup!
