Culture: Spring or fall, beets are hardy and easy to grow. Can be sown almost as soon as ground can be worked in spring. Minimum germination temperature 40°, optimal range 60–85°. For full-sized beets, you must thin to at least 3" apart. Early thinnings make good salad greens; baby-beet thinnings cooked with tops are a Yankee delight!
PM: Powdery Mildew
DM: Downy Mildew
CLS: Cercospora Leaf Spot looks like someone shot a series of small target-like circles in the foliage. Prolonged periods of rainfall and high humidity exacerbate this disease. In serious cases the spots darken and extend. Rotating crops, removing plant debris, and wider spacing to ensure adequate air circulation are preventive measures.
Scab, the same disease that afflicts potatoes, causes rough brown spots on the skin. Adequate irrigation is a preventive.
