Weed Services questions, answered by experts

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. 

Yes, organic herbicides and natural prevention methods reduce chemical use.

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?

Crabgrass is very resilient, and homemade solutions like vinegar may not be strong enough. Typically, hand-weeding is the most effective option that doesn’t involve harmful chemicals. You can use corn-meal gluten as a natural pre-emergent herbicide, but it’s not as effective as chemical weed killers.
