Where do you live? Please be pretty specific since SoCal stretches from San Diego to Blythe to almost Bakersfield with altitudes ranging from -40 to 10,000 feet.

What kind of grass do you have? Cool season grasses like Marathon fescue, Kentucky bluegrass, and rye should only be planted west of I-5 or 405 freeways or above 3,000 feet. The rest should be warm season grasses like bermuda, St Augustine, zoysia, or buffalo grass (UC Verde being the best available). These warm season grasses also do well along the coast.

Daily watering is the worst thing you can do to your lawn. There were several forum writers this past summer who fixed their lawn issues by switching from frequent watering to infrequent watering. The mantra for lawn watering is deep and infrequent. Watering depth should always be 1 inch every time you water. Measure that by placing tuna or cat food cans around the yard and time how long it takes to fill the cans with your sprinkler(s). The frequency of watering depends on a lot of factors (sun, shade, temperature, soil type, grass type, mowing height, wind, humidity, and whether it has rained recently), but they almost always boil down to the high temperature for the day. If you have temps above 100, then water one inch, once every 5 days. With temps above 90, water once a week. With temps between 80 and 90, water once every 2 weeks. With temps between 70 and 80, water once every 3 weeks. Below 70 degrees, water once a month. I realize that nobody in SoCal (or Florida) would think this would work, but it does. It works perfectly well from Phoenix to Vermont.

Think of this as your starting point. If you are currently watering daily, you cannot suddenly turn off the water and wait for a month. Why? Because the roots on your grass are short due to the frequent watering. You're going to have to ease into the deep and infrequent watering to get your roots growing much deeper. It might take a month of watering deeply and watching the grass to let it tell you when it needs water. Stretch it out until you see the first signs of drought stress and then water a full inch. Then stretch it out again.

You're about to get into the rainy season...if el Nino cooperates. El Nino wasn't a thing when I lived there, but winter was always the season of the most rain. So you probably won't have to water until March or April.

So if you can answer the questions above, I can usually get more specific for you. I lived in lots of places from Indio to the beach and visited the San Diego and Santa Barbara regions a lot.

We live in Long Beach. I live close to the 405, west of it. Unfortunately I am not sure what grass we have, I know it’s not expensive grass like St Augustine. The previous owners put the sod in this past Spring or summer.

@dchall_san_antonio I will post a picture tomorrow, thanks!

For the lawn at my own home in inland SoCal, I water it 2-3 times a week with a deep watering in the early morning hours. To prevent run-off, the sprinklers are set to run 3x5-minute intervals, spaced out over an hour. During winter if it rains frequently, the grass is seldom watered.

It rained this week, finally! so it’s looking pretty good for Southern California grass :) @dchall_san_antonio

Its tall fescue, which is the type sod used over 90% of the time for homeowners in So. Cal

Its fairly water efficient if watered deep and infrequent, and use weed preventer in spring and fall - to keep out weedy grasses that are hard to control with post emergent herbicide- ( annual bluegrass, bermuda, etc. )

Agree with Tom. Even though fescue is used 90% of the time, it is completely inappropriate if you live inland. And I define inland as east of the 5 and 405 freeways. If you don't get low clouds or fog every morning until 11am, then you should have a warm season grass. For example, the OP is close to Compton, but I would rather have bermuda or St Augustine if I lived there.

Most lawns in So. Cal sodded with Tall fescue- end up being over run with naturalized weedy grasses. Usually its Bermuda, Kikuyu, wire grass, crabgrass, poa, and nut sedge.........and throw in a little white clover too !
