Crabgrass is a summer annual plant in all climates as far as I know. Can you post a picture of the grass you're calling crabgrass. It probably is crabgrass but there are some who refer to other weeds as crabgrass.

One problem is that crabgrass thrives under the same conditions that bermuda thrives under - hot weather and mowed short. Then if you water more than once per week, you're guaranteed to get crabgrass. I used to live between Aviation and the 405 in Hawthorne. My lawn was miserable, but I didn't know what I know now about lawns. If I had it to do over again for that location I would put in either Kentucky bluegrass (fine blade) or St Augustine (coarse blade). Either of those should keep the crabgrass out of the lawn without any effort.

Here's a friend's house in Huntington Beach...

That is KBG. He mows and waters once per week. Fertilizes with used coffee grounds whenever he remembers - about once per year. It never goes dormant that close to the beach.

The reason I mention alternatives to what you have is the fact that you have both crabgrass and kikuyu. Those are the most noxious weeds you can get and you have both. Furthermore you have common bermuda. There isn't anything I consider worth saving or even spending any money on. Bermuda is one of the hardest grasses to keep looking really nice. I know St Aug is really easy and I suspect KBG can be really easy in your area. So, are you really going to keep the bermuda? There's going to be a lot of dead bermuda if you really want to clean things up.

The hard part about bermuda is keeping it dense enough to fight off weeds. That requires mowing twice weekly at a low setting, watering once weekly, and fertilizing once monthly. If you can't do that then you face a life of weeds and herbicides. Other grasses get mowed much higher (helps fight off weeds), watered weekly (all grasses need water once per week), and fertilized at most 3x per year.

Thanks for the response. Your friend's lawn looks beautiful. Ours, not nearly as nice. Unless we can just start throwing KBG seed in the lawn, unfortunately the bermuda/kikuyu is here to stay. If we have to go through scraping and overhauling again, the grass no matter the type, is going to stay out. My husbands been wanting to do a xeriscape in its place, but I was hoping to keep at least a little grass in the yard. Should I attempt a pre-emergent to stop anything else from popping up? I will try to take a pic in the morning, but I'm pretty positive it's crab. Low lying, huge blades, growing in shape of a crab.

Here's a photo. Should I hit them with a bunch of herbicide? Just keep pulling until winter? I don't want to kill everything.

Thanks!
