Chard
Swiss chard is planted in the spring about the same time as beets. A single planting will produce greens throughout the season. Sow the seed in rows and thin to 4 to 8 inches.
If you harvest only the outer leaves, the plant will continue to produce greens throughout the season. A few plants will supply an average family.
