The cardiovascular system consists of the heart, blood vessels, and the approximately 5 liters of blood that the blood vessels transport.
This planter also holds begonia, marigolds, and a pepper plant. Growing Swiss chard works best in rich, moist soil with a soil pH between 6.0 and 6.8. Plant about 12 to 18 inches apart in fertile soil, watering directly after planting. Work nitrogen-rich amendments such as blood meal, cottonseed meal, feather meal, or composted manure into the ground before planting.
Spacing depends on how plants will be harvested. If seed is drilled in the row and the young collard plants are to be harvested, similar to turnip greens, the rows may be 12 to 18 inches apart and the plants 2 to 4 inches apart. If 'head collards' are grown, the rows should be 18 to 35 inches apart and plants set or thinned to 12 to 18 inches apart in the row.
