Unless you're growing in pots you shouldn't need to water every day. Once a week you should give them a good long drink of 1-2 inches. Set you sprinkler up and put a dish(a cool whip container works ) in the garden at farthest point the sprinkler reaches in your garden, when that dish has about 1 inch of water you can turn it off. If you get rain you may not have to water at all.
