Beets make a good short season, intensively cultivated crop. Beets provide quick baby greens for salad mix, mature leaves for cooking, and sweet roots for cooking, canning, and winter storage. Both the root and greens are good sources of vitamins and minerals.
To grow beets in the Fall you must be aware of your local weather conditions when deciding when to plant (first average frost date, unusual historical fall extremes, etc) if you are not in the South or along the coasts.
Does best in cool or warm weather and moist soil. Sow in well-drained soil that is reasonably warm - the soil must be around 60 degrees for good germination.. Light frost at night won't hurt, but heavy frost or freezes might be too much.
Medicinal: Red Beets stimulate the immune system, and have possible anti-cancer properties. Antioxidant.
