Beets are high in vitamin A in C, and both tops and roots are edible and delicious. Make first planting early and every 2 to 3 weeks until August for a steady supply. Beets are ready to eat as soon as they reach golf ball size. Keep well-watered as drought will result in tough or woody roots. One packet will plant an approximate 20 to 30 foot row. Use 1 oz. for a 100 foot row.
