Fall Vegetable Garden Calendar
Washington County
Vegetable gardening in Washington County can be rewarding and successful. Locations within Washington county vary widely; in elevation which has a significant influence on the climate, and growing season. For example, St. George has an elevation of 2,624 feet and a frost-free growing season of more than six months. Enterprise has an elevation of 5,346 feet, and the frost-free season begins the first week of June and ends in mid-September. Knowing when to plant is critical in areas where the season is short (about 3 ½ months).

Much of Washington County has a long growing season extending well into October. Higher elevations will likely see frost earlier, so plan accordingly. On transplanted vegetables such as broccoli and cabbage, plan on needing an additional month after planting to allow them to mature. It is true that many of these can withstand a light frost without injury, but they should be well established before frost. Some crops such as lettuce, spinach, and beets will handle the frost quite well. Onions that are to be kept for storage actually do better if planted now and then harvested next summer.
