If you live west of the Cascades, there's a good chance you can garden almost year-round with a little extra effort. Many cool-season crops produce well in the fall and even hold through the winter if protected. Good crops for fall and winter gardens include salad greens, cabbage, broccoli, kale, Brussels sprouts, carrots, leeks, beets, turnips, scallions, parsley, cilantro, spinach, and parsnips. You can plant these vegetables in mid- to late summer after you harvest spring crops and space is available. Getting started The first key to a successful fall and winter garden is location.
Good drainage is essential, and raised beds are best.
If your soil doesn't drain well, amend it with organic matter such as compost. Look for an area that gets as much sun as possible during winter. A south-facing slope is ideal. Make sure your winter garden is easily accessible. It's no fun to slog through mud and cold rain to harvest your crops.
