Drippers are the best choice for low pressure situations, individual plants or for plants that won't tolerate water on the foliage. Sprayers are good for evenly wetting larger areas and for increasing humidity around moisture-loving plants. Sprayers are also useful in areas where you want to minimize the amount of tubing visible in your plantings or where it's too difficult to lay emitter tubing or soaker dripline. Sprayers and mini-sprinklers tend to put out much more water than drippers, but are still water saving compared to traditional sprinkler systems.
