What You Need for This Project

Herbicide 101

There are herbicides for every type of weed! To help break it down we’ve divided them into two categories: pre-emergent (prevention) and post-emergent (removal). 

Pre-Emergent: More of a preventive tool, these herbicides are best for weeds that haven’t grown yet. Pre-emergent herbicides create a chemical barrier on the top layer of soil which coats seeds and prevents them from growing roots. 

Post-Emergent: Use this herbicide to kill weeds once they’ve germinated. Post-emergent herbicides are applied directly to the weeds and will kill the weed from the root. 
 
Step One

Examine Your Lawn

Take a closer look at your lawn to determine which types of weeds are growing. Most treatments are made to target specific weeds. 
Step Two

Find the Perfect Treatment

Different herbicides are used for different weeds. If you’re targeting weeds before the growing season, you’ll need a pre-emergent treatment. If you’re targeting weeds that have already grown, you’ll need to purchase a post-emergent treatment. 
Step Three

Kill the Weeds

Using protective gear like gloves and a face mask, apply the treatment to the affected areas. Always be sure to read the manufacturer’s instructions before starting! 
Step Four

Lawn Maintenance & Weed Prevention

Set up a lawn maintenance schedule to keep your lawn weed-free. It’s recommended that lawn maintenance is paid attention to all year-round. 

  • Spring: Use pre-emergent treatment and hand pick any weeds. 
  • Summer: Mow your lawn regularly. 
  • Fall: Seed and aerate your lawn.
  • Winter Prep: Give your lawn a short cut and fertilize treatment.
