Can I kill crabgrass but not clover?

Hello--I have a bermudagrass lawn that's infested with crabgrass. The problem is that I also have a lot of clover that I actually like. It is the regular type of lawn clover (not red clover like you see in pastures), but it has these dark raspberry-pink flowers that are really pretty. Otherwise I could just reseed the clover after getting rid of the crabgrass, but I don't know where to find this pink clover seed. This is at a new (old) house, and I haven't done anything to the lawn yet except mow it.

I usually avoid herbicides/pesticides and haven't bought any in years, but I was thinking of using a product called Green Light Crabgrass preventer to help get the crabgrass under control, and then switch back to organics. It is also supposed to kill the crabgrass in the early stages. Does anyone here know if the Green Light product will kill the clover? I have looked online for the information, but I can't find the full label info for it. Also, does the green light stuff actually work on crabgrass?

I used to use corn gluten meal, I'm not sure where to buy it here, but I'm going to try to find some. My old lawn didn't have clover, and I am also wondering if CGM will get rid of it over time? Thanks everybody.

OK 2 problems here. Whatever product you use to kill CG will kill clover.

Second problem is if you have clover in Bermuda lawn indicates you are not fertilizing the grass properly with enough nitrogen. Otherwise the clover would not be there to begin with.

This is interesting. Apparently the OP likes the mix of bermuda and clover. And as TW pointed out, you likely would not have any clover if you had been fertilizing along the way. The next irony is that the reason you have crabgrass is the same reason you have clover. You have stopped fertilizing and the bermuda has thinned out allowing other plants to move in.

Yes, I hadn't fertilized yet because I just moved here. I ended up buying a preemergent crabgrass preventer (prodiamine/Barricade) + feed that supposedly doesn't kill clover. It probably won't make a big difference since the crabgrass has already sprouted, but maybe it will keep it from spreading and I can apply it earlier next year.

Julie search around this forum and other lawn forums for the Bermuda Bible, read it and come back with questions.

You are just going to have to bite the bullet, if you want Bermuda you have to work at it and nuke the clover and CG with post emergence and fertilize your Bermuda 5 to 8 time per year depending on your location.
