Baja, that's sort of what I'm getting at. That if plants from a Mediterranean climate are adapted to a warm/hot dry summer and a cool wet winter they should be watered more in the winter and spring wet season and less in the summer, which is contrary to the typical recommendation. Like I said in the beginning, the typical recommendation (even from the Native Plant Society) is to stop watering when it starts raining and start again when it stops raining. That sounds backwards to me. I would turn every winter into an El Nino winter and water very minimally in the summer.
Plants from other climates would obviously need summer watering. Even some of those will survive on less watering than they typically receive.
