Adding vinegar to your lawn increases the acidity of the area, which can kill quack grass present above the ground. However, putting vinegar in your yard will also kill the grass. Unfortunately, the below-ground quack grass rhizomes remain very much alive in the presence of vinegar and will soon sprout again.

There are a few things you should ask a weed service company before hiring to ensure you’re choosing the best professional for the job:

• How often will you apply herbicides?

• Do you include any spot treatments or manual weed removal in your pricing?

• Do you offer pet-safe and kid-safe herbicides?

• What other lawn services can you provide?

• Do you offer any kind of guarantee for the work performed?

• Are you properly licensed and fully insured?

• Do you have any customer references I could speak with?
