Gardening on a Grade

When we were selecting an area for our garden beds we were not only looking for an area not too far from the house but with full sun and easy access to our outdoor water hydrant.  The area on our property that best met this criteria sloped to the west.  A garden on slope is not ideal because the rain or sprinkler water will shed off to the lowest area leaving the elevated side too dry and the lower side too wet. 
To accommodate for the east to west grade I chose to garden in HILLED rows, as pictured above.  Since our slope is an east to west slope our rows are hilled perpendicular, or north to south.  The low space between the rows acts as a well to hold moisture and prevent excessive water shed.  The hills also encourage deeper roots systems, adding to the plant's overall health.
