While many gardens may start winding down in September, southern areas of the United States are coming into the prime gardening season. Even if you maintain a garden in the northern regions, there are still fast-growing vegetables that you can plant in September to keep your vegetable garden producing well. Autumn is an ideal time to take advantage of the cooler weather. Depending on where you live, some root vegetables and salad greens grow just as well in the fall as they do in the spring.
