Wow! That was more information about grass than I've ever read in one spot! I wish it was as easy as you make it sound. My sprinklers are just they standard "pop up" ones. I'll put out the cans in all areas, regardless of green or brown and see how long it takes to fill them in each of those areas...?
So I understand completely, are you saying water for the 1 inch and not the duration? Figure out the interval that it takes for the 1 inch, then water once a week for that interval....? And the dead / dry / hard areas.... Any suggestions on how to bring them back and re-seed again (do I till, lay seed and cover with topper? A combination, a different method?)
Thank you again. Looking forward to seeing you suggest, and get started on bringing my lawn back!
I live in Anaheim Hills and I'll post some pictures of my lawns (front and back) tomorrow as the sun has set here this evening.
Thank you again for all of your suggestions and willingness to help.
