In-Ground Sprinkler
Often set on an automatic timer, in-ground sprinklers can be installed flush to the ground, only popping up when they're in use. These systems are connected to a network of pipes underneath your yard and should typically be installed by a professional. If you plan on using in-ground sprinkler system, be sure to organize your plants into hydrozones — grouped according to low, moderate and high water use — to ensure that the right kind of head delivers the appropriate amount of water.
