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.
Pull any weeds and grass out of the planting area by hand or use a shovel for heavy sod coverage. Loosen the soil to the depth of 6 inches with a garden hoe or spading fork. Rake the prepared soil smooth and level. Lay the seeds on top of the soil so that they are 3 to 6 inches apart. If creating rows, space the rows 12 to 18 inches apart. Do not press the seeds into the soil. Cover the seeds with 1/8 inch of sand or well-rotted compost. Blue flax seeds need light to germinate.
