6. Vetiver grass is a great way to build natural terraces. Using an A-frame like you would when laying out a swale, you plant the grass plugs on contour. We planted ours about 10 inches apart, which worked great. As it grew in, it clumped together in an almost continuous "fence" of grass. Laying sticks up against the clumps of vetiver on the uphill side, and back-filling mulch up against the grass, it began to create a level terrace on the uphill side of the grass. 3 years later, it's clearly working to make a terrace.
