Post-emergent herbicides can also be used to kill existing crabgrass, but be sure to follow instructions carefully to avoid damage to your grass.

In St. Augustine grass it is most important to apply a crabgrass preventer and fertilizer in early Spring. Far easier to prevent than to kill later as almost anything that kills crabgrass can kill St. Augustine grass. Our Ace Hardware sells a crabgrass preventer in the Spring. They now have a product called Garden Weasel Crabgrass killer. A container of this powder will do up to 200 sq. ft. Must be applied to wet leaves on the crabgrass. I found I did a second application on some "tough guys" but it worked fine.

Yes, crabgrass is a C4 plant. C4 plants have a specialized mechanism for carbon fixation that allows them to adapt to hot and dry conditions, making them well-suited for growth in environments where C3 plants may struggle.
Crabgrass can be very annoying and can turn a perfectly fine lawn into a disaster if not treated immediately. There are several options for crabgrass removal. First option: If the crabgrass is localized to few areas of the lawn they do sell sprays that will destroy ONLY crabgrass. Bayer makes a very good crabgrass spray that you will be able to pick up at a Home Depot or Lowe's. Once the problem grass is gone, you can spot seed and get real grass back. Second option: Once again, if the crabgrass is localized to few areas of the lawn to may be able to just pull the crabgrass out by hand. A little more labor intensive, but will save you a few bucks. Once problem grass is gone, just spot seed. Also make sure if you are spot seeding that you scratch the dirt up a bit on the areas you are seeding. Once seed is put down, very gently back-rake the spot ( if the area is tiny you can use your hands to just try to cover the seed with a LITTLE bit of dirt just to hold it in place ). Back-raking is just taking a rake, and putting on its backside. Make sure to water daily. A little bit of peat moss works great for retaining water. Third option: If the crabgrass has taken over more than half of your lawn, you may need to till the affected areas. After tilling, remove the crabgrass with a grading rake. Then seed the area and start new. This will be the worst case scenario though.
