I am, relatively, a newbie with lawn irrigation. We bought our place 2 years ago.

When we got back in October (yes, sigh...we are "cloggers" or "snowbirds" or "snowflakes"- I get confused with all of these terms) our lawn looked pretty good except in the most sunbaked areas. There it was bare, or infested with weeds.

Here's the scenario: corner lot, with the larger expanse on the western side. Half of that expanse is shaded with a big oak. The grass in the front yard, and the grass under the oak looks good, but about 50% of the expanse on the western side, unshaded, is parched. Unfortunately, this expanse is irrigated by two zones, but each zone waters half of the shaded area and half of the desert. So I can't just alter the programmed times. So, I'm experimenting with different flow-rate nozzles for the unshaded areas.

St. Augustine grass.
My question for those who enjoy trying to finesse this sort of thing, is what flow rates do you use with your nozzles? Do you use different flow rates in sun, in shade, and/or change with the season?

You don't have to tell me I'm overthinking this. I already know that. But it's what I do, and I enjoy it, so I'm unlikely to change.

Thanks in advance...
