Cover the sprinkler heads with fake, hollow rocks. These landscape features have a hollow center but an exterior appearance that looks like stone. When you want to use the sprinklers, simply lift the covers off and use the system.
Plant bushes over the sprinkler heads for a system that no longer functions. Position the bushes so the sprinkler heads are completely concealed.
Install a sprinkler system with retractable heads. Turn the system off and the sprinkler heads retreat back into the ground under a cover, hiding them from view.
Cover the sprinkler heads of a broken system with mulch or pebbles. Plant decorative shrubs or flowers in the ground covering to turn the space into a small garden.
Place potted plants over the sprinkler heads. Remove the pots from each sprinkler head when you need to water the area.
