we are doing a sod job, and some minor bed work (adding boulders, stone, etc) there are established plants there already. the home owner is having a sprinkler system installed. my advice was to just have enough heads to water the lawn, i don't want any in the beds, or any that shoot water into the beds. the sprinkler installer disagreed with me, saying the beds /plants should be watered at the same time as the lawn. who is right?
