Select a moist area in your garden such as a place around a pond or water feature. The sawgrass needs consistently moist soil to grow.
Plant the sawgrass in the summer around the edge of the pond or water feature. Dig holes as deep as the root balls, and plant them at the water's edge.
Harvest the leaves of the sawgrass when they are young if you want to eat them. Pick the leaves from the plant when they are about 2 to 3 inches long, soft and supple.
Divide the sawgrass in the spring if it starts crowding the side of the pond or water feature. Dig up the sawgrass and pull apart the clumps of roots with your hands. Dig new holes for the sawgrass and place it around the pond or water feature.
