Add lime.  Fall is a great time to add lime to your garden plot.  Use the results of your soil test to know the right amount to add.  If you are not testing your soil a general rule is to apply 5 to 10 pounds of lime per 100 square feet.  Cover your soil with garden mulch or burlap after liming.

Winterize your garden.  Plant a cover crop or mulch your plot. If nature has already covered your veggie plot with a layer of weeds you can actually leave them to serve as a cover crop.  Just be sure to pull them in the spring before they go to seed.
