Heart & Blood Vessels: Your Coronary Arteries. The heart receives its own supply of blood from the coronary arteries. Two major coronary arteries branch off from the aorta near the point where the aorta and the left ventricle meet. These arteries and their branches supply all parts of the heart muscle with blood.
Mound the soil into a raised rows to a height of 8 to 12 inches and 6 to 8 inches wide, spaced 3 to 4 feet apart. This provides loose soil for the formation of tubers and promotes healthy growth. Plant sweet potato slips 10 to 12 inches apart and firm the soil down with your hands to secure the plant. Water thoroughly to moisten the mound of soil. Keep soil evenly moist until new growth appears. Mulch with organic matter to conserve moisture and prevent weeds.
Tubers should be planted in the garden 2-3 weeks before the last frost. Planting and Spacing: Plant potato seed pieces 4-6 inches deep and 10-12 inches apart in the row. Space the rows 30-36 inches apart.Potato should be planted when soils are at least 50ÂºF. Generally, soil is hilled or mounded around the plants as they grow. Hills provide room for the tubers to develop, provide added soil drainage, and minimize tuber greening later in the year.pace the rows 30-36 inches apart.
