Types

• There are two types of weeds to watch for: grassy, such as crabgrass and bluegrass; and broadleaf weeds, such as chickweed. Some are annual and others perennial.
  
  

Control

• Pre-emergence herbicides work on the sprouts and post-emergent herbicides take care of those weeds that are already infesting the lawn. Granular formulas work well when applied in late winter into early fall.
  
  

Considerations

• The best way to prevent weeds in your zoysiagrass is by keeping it healthy and thick. Consult with your county cooperative extension agent for advice on when to fertilize and water in your area.
