You should add 1 to 4 inches of mulch, depending on your garden type and needs. Keep in mind that no amount of mulch can completely prevent weeds, but a heavier coverage (closer to 4 inches) can suppress weeds enough that you are only seeing them sprout every few weeks. Finer mulch prevents weeds more effectively than large mulch, so if you’re using mulched leaves or shredded bark, 1 to 2 inches will likely suffice, while 3 to 4 inches is best for larger mulch, like bark chips or straw.

Mowing your grass regularly, especially if you’re mowing close to the ground, can help kill Johnsongrass. Frequent mowing helps limit the spread of Johnsongrass and can even deplete carbohydrate reserves in rhizomes over time. The more time you leave in between mowing, the more likely Johnsongrass is to regrow and take over your lawn. 

Some of the particular herbicides that work best to get rid of nut grass without killing the grass include Halosulfuron-methyl, mesotrione, sulfentrazone, and metsulfuron. A herbicide like glyphosate would kill nutgrass, but it will kill nearby plants, too.

The best time to hire a weed service company is in the early spring. This allows them to apply a pre-emergent weed killer that stops weeds from taking root, making maintenance for the rest of the season much easier. Following the initial spring application, a monthly service through the summer and early fall is a good idea for ongoing weed control. These regular treatments, combined with manual removal or spot treatment, should be sufficient to maintain a weed-free yard. Alternatively, you can hire a professional in the fall for the following year, as some companies may offer better rates on contracts signed before the busy spring season.
