Growing vegetables in the winter is a lot of fun and a whole lot less work. Cool season vegetables, such as the purple carrots above, taste more succulent when they are grown during the colder part of the year. Radish are not as hot either. Lettuce and other salad greens practically melt in your mouth.
Weeds are not an issue as long as you start with clean beds. Put a layer of straw between the rows once the plants start to grow. The straw blocks weeds, breaks down over the winter adding nutrients to your soil and helps keep the soil warm. In fact many vegetables, such as potatoes, carrots, radish and turnip, are easy to store in the ground all winter long if you cover them with a heavy layer of straw before winter sets in.
