The fastest ways to kill weeds and unwanted grass include burning them, pouring boiling water on them, or pulling them out by hand, as these methods work almost instantaneously. For a quick-acting solution that works within a few hours, you can use a commercial-grade herbicide like glyphosate or a DIY vinegar, salt, and dish soap mixture. While effective, be aware that commercial herbicides introduce chemicals into your lawn. The slowest method for killing weeds is to starve them of sunlight and nutrients using mulch or fabric covers.

There are tools known as “sprinkler donuts” that are specially designed to aid in cutting the grass around your sprinkler heads by protecting them from your mower or weed whacker. You can also use a pair of hand shears to do the job manually if you’re willing to get a little dirty.

Johnsongrass and crabgrass are invasive weeds that can overtake your lawn. Crabgrass is a low-growing grass most often seen in lawns, flower beds, and vegetable gardens. While you may find Johnsongrass growing in your lawn, it will also grow in pastures, crop fields, and the edge of the road. Johnsongrass is much coarser than crabgrass. If left alone, Johnsongrass can grow up to 8 feet tall. 

There are many options to eradicate weeds right down to the roots. Vinegar works, but it takes a week or so to do its thing, and the same goes for many commercially available herbicides. Boiled water is a quick way to kill off roots, or you can pull up weeds at the root.
