We have had an early warm spell followed by a hard freeze, in the teens several mornings. Will the freeze kill any crabgrass that has germinated and sprouted? Should I wait until soil temps warm again for crabgrass preventer or apply ASAP?
The frost is not likely going to kill the Crabgrass.
Spring is a good time to apply selective herbicides.
Check with your local County Extension Office for advise on weed control in your region.

Hello, My lawn is about 1050 sq. mts. But I can't seem to control the weeds and Canada that spring about all over the place in an erratic way. I've seen on tv about ortho weed and crabgrass killer. Is this or some other brand any good? Thank you. Rudy
It can work, just know that there is some risk to the other plants and grasses in the area. Since it is a highly invasive grass, there is a good chance that it will return in the future.

I thought I remembered wetting the grass and then applying epsom salt would eliminate crab grass?
Essentially, yes, but it would be the equivalent of giving it too much food. This is a source of magnesium and sulfur for plants, and is used as such.
There are many ways to get rid of grasses in an area. Boiling water and vinegar are two very good remedies for killing grasses.
Boiling water will kill anything on contact, without turning the soil into a toxic mess. This may require multiple applications to kill off remaining grasses and germinated seeds.
Vinegar will kill any plant when sprayed directly onto it. I would avoid getting this in the soil... Just on the blades of grass. This will make the soil temporarily sterile. Nothing will grow here for a few weeks.
Those are just two ways to safely remove grass, but there are many, many more ways. I would recommend saving the epsom salt for feeding the plants, though.
I have a lot of crabgrass in my lawn. Is there any way to get rid of it besides, re-sodding the lawn? I have about 3000 sq. ft of front lawn. Thanks Rhonda
