Do You Want to Kill Existing Crabgrass or Stop It Before It Starts?

Some formulas of herbicides will serve as all-in-one products – they’ll prevent the emergence of new seedlings and kill the crabgrass that is already there.

If you have a problem with crabgrass every year, you can look for the best crabgrass preventer and the best crabgrass killer all rolled into one. If you just have a random patch here or there, you can opt for only the post-emergent crabgrass killer.

Do You Want to Protect the Rest of Your Yard?

Is your yard completely overrun by crabgrass? Does it seem like a pipe dream that you can put down enough product to take care of the serious overgrowth you’re facing?

If so, you might want to use a non-selective crabgrass killer. That simply means the herbicide will kill your crabgrass, but it might also kill everything in its path. You may have to be prepared to seed a new lawn if you go this route, but with this much crabgrass in your yard, you need to get aggressive with treatment.

If you just have a few problem areas and the rest of your lawn is still in good shape, you can opt for a selective herbicide that only knocks out crabgrass, leaving the rest of your plants healthy.

How Do I Want to Apply the Crabgrass Killer?

You have a couple of options when it comes to how you’ll apply the crabgrass killer, and which type you choose depends upon your comfort level.

You can purchase a ready-to-use crabgrass killer that will come in a spray bottle. All you have to do is spray it on your trouble areas. It doesn’t get much easier than that.

For bigger areas, you may want to consider getting the kind of herbicide that will attach to your garden hose for the application. That’s a little less convenient, but it may save you time and money.

Which way you choose really depends upon your comfort level with handling herbicides.
