Broad Leaf Weed Control

Broadleaf Weed Control

Compared to grassy weeds, broadleaf weeds are much easier identify, eliminate, and control.  There is a wide variety of chemicals and brands in the market that do an excellent job of battling these weeds.  Like with grassy weeds, it is key to identify which broadleaf you are targeting to help get the best results.  Some key features that differentiate broadleaf weeds from grass weeds are:

  • wider leaf blades
  • main vein divides the leaf with smaller ones producing a net-like pattern
  • some leafs can be circular (Dollarweed)
  • produce colorful flowers with different shapes and sizes
  • flowers can be key to help identify the species

Broadleaf weeds may germinate and grow at different times of the year and also have longer life cycles.  This is very important because it helps determine when to apply pre-emergents and post emergents.  We can break down these weeds into three groups that help us better understand how to eliminate them.

  • Winter Annual Broadleaf Weeds
  • Summer Annual Broadleaf Weeds
  • Perennial Broadleaf Weeds

Winter Annual Broadleaf Weeds

  • germinate late summer through early fall
  • germination is the process of development for weeds
  • best time to apply post-emergent herbicides is in the spring while there is active growth
  • some can be controlled/prevented with pre-emergent application in the fall (common chickweed)

Examples

  • Prickly Lettuce
  • Common Chickweed
  • Henbit
  • Shepherd's Purse
  • Hairy Bittercress
  • Dead Nettle

Summer Annual Broadleaf Weeds

  • germination begins in early spring through the rest of the growing season (summer)
  • growing season depends on your geographical location
  • northern areas are going to have a later and shorter growing season 
  • the complete life cycle in one growing season
  • as with winter annuals, the best time to apply post-emergent herbicides is during active growth

Examples

  • Black Medic 
  • Carpetweed
  • Knotweed
  • Mallow
  • Purslane

Perennial Broadleaf Weeds 

Cool Season

  • year-long life cycle
  • reproduce by seed and/or other vegetative means
  • germination occurs in winter so pre-emergents would need to be applied in late fall
  • active growth is during the spring and fall (best time to apply post emergents)
  • these weeds for dormant during the summer
  • multiple applications may be necessary because of the year-long growth cycle

Warm Season 

  • Reproduce by seed and/or other vegetative means
  • Germination occurs in spring (best time to apply pre-emergents)
  • Active growth is during the summer months (best time to apply post-emergent herbicides)
  • These weeds go dormant during the winter
  • Multiple applications may be necessary

Examples

  • Clover (cool season)
  • Dollarweed (warm season)
  • Plantain Buckhorn (cool season)
  • Oxalis
  • Ground Ivy
  • Broadleaf Plantain
  • Beggarweed
  • Buttonweed
  • Dandelion
