Onions are easy to grow. They perform best in well-drained, slightly acidic, fertile soils in full sun. Heavy soils can be improved by incorporating organic matter, such as compost, into the soil. Onions require higher fertility levels than most other vegetables. Apply 1 to 2 pounds of an all-purpose garden fertilizer, such as 10-10-10, per 100 square feet and till into the soil prior to planting. Four to five weeks after planting, sidedress with additional fertilizer. Sprinkle 1 pound of an all-purpose garden fertilizer per 100 feet of row. Place the fertilizer in a narrow band about 2 to 3 inches from the base of the onion plants.
All parts of a beet plant are edible. The tops, or greens, can be cooked and enjoyed like spinach or turnip greens. But it is the root, the pretty part, that we prefer. While the bulbous roots are most often dark red, they can also be yellow, white and striped like a candy cane. Don't let the color fool you - even the white ones are as sweet and tasty as the red ones! Their shape can vary as well. They can be round, flat or cylindrical.
