Follow these steps for great results in the garden.
Preparation. Plant greens in the ground or in containers. In the ground, amend soil by mixing in 3 to 4 inches of compost or other organic matter. If planting in containers, choose a pot at least 10 inches in diameter and fill it with potting soil to within 1 to 2 inches of the rim.
Watering. Keep the soil moist but not soggy (check daily if starting from seed).
Feeding. Fertilize with fish emulsion every two weeks, or use a dry, organic fertilizer according to package directions.
Planting. Start with seedlings purchased at the nursery and plant closer together than recommended, 5 to 6 inches apart. Or sow seeds 1 inch apart in thoroughly moist soil and thin to 5 to 6 inches apart when plants are ½ inch tall. Make sure to grow enough for your needs.
Harvesting. Snip off individual leaves when they're about 4 inches long. New leaves will continue to form.
Planting. Sow seeds ¼ inch apart (mix with sand to aid distribution). Thin only if seeds were sown too closely. Sow successive crops every two to three weeks for a steady harvest.
Harvesting. Snip off clusters of sprouts right above the soil line when the first set of true leaves forms; they follow the initial cotyledons (seed leaves).
