Q.Should I till up my raised beds in the fall?
I grow veges in my raised beds,they are cleaned out now.

It isn't necessary and is actually not a good idea to till the soil in your raised bed. It turns out that tilling does more harm than good. I would chop leaves with your mower and put several inches over the beds. If leaves aren't available, put down a couple inches of compost. Otherwise winter prep is making sure you remove all plant material so any unwanted germs or bugs don't overwinter in the bed. https://www.gardeningknowhow.com/edible/vegetables/vgen/veggie-garden-winter-prep.htm
