Raised Row Gardening

We build raised rows when making our garden beds. The beds are created above the flat surface of the terraces that my late mom built many years ago. These garden beds are only about 2 feet wide and 10-12 feet long with a narrow path in between the rows. Some beds are short depending on the contour of the hill and the width of the space above the terraced hill. Sometimes, one terrace could only accomodate 3 or 4 garden beds. At the edge of the stone terraces are some guava trees or coffee trees. We do not have a source of water in this hill garden other than the rain water that gets impounded on some shallow ponds during the rainy season. This is what we use for watering the newly planted coffee trees during summer but the water doesn't last long because of evaporation. So during the onset of the rainy season, that is when we plant sweet potatoes so we do not have to worry about watering them. We use sweet potato vines as planting materials. By the time that the rainy season is over, the sweet potatoes would have grown some roots. We use rabbit manure as fertilizer for the plants and we use the vines and leaves of the sweet potatoes to feed our rabbits. Never mind the root crops because the rats in the field always beats us to it, we're mostly interested in the vines and leaves anyway.
