Broadleaf and Narrow Leaf Plantains
The two types of plantains that are commonly found in lawns are broadleaf plantain (Plantago major) and narrow-leaf, or buckhorn plant (P. lanceolata). These two perennial weeds are easily differentiated by their leaves. Broadleaf plantains have smooth, oval leaves while buckhorn plantain has ribbed, lance-shaped leaves. Both types are found throughout the U.S. where they thrive in compacted soil.
Preventing Plantain Lawn Weeds
The best way to prevent plantains in the lawn is to keep the soil aerated and healthy. Aerate compacted soil and follow a regular schedule of fertilization at least twice a year. Water the lawn deeply when there is less than an inch (2.5 cm.) of rainfall in a week. A healthy lawn crowds out plantains, but the plantains crowd out the grass when the lawn is in poor condition. Plantain weeds also contaminate mowers and other equipment used on the lawn. Clean your equipment thoroughly before using it again to prevent the spread of planting lawn weeds.
Plantain Weed Treatment
Plantain control can be achieved by pulling or digging the plants as they emerge when the infested area is small. This is easiest in sandy soil or soil that has been softened by rain or irrigation. You may have to dig and pull the plants in the area several times before achieving complete control. The weeds must be removed before they have a chance to produce seeds. When large numbers of the weeds are present, plantain lawn weeds are best controlled with herbicides. Choose a post-emergent herbicide labeled for plantain control. Post-emergent herbicides are most effective against plantains in fall when the plants are moving carbohydrates to the roots for winter storage. You can also apply the herbicides in spring. Carefully follow the label instructions regarding mixing, timing, and application procedures. Avoid spraying when temperatures are above 85 degrees F. (29 C.) and on windy days. Store any unused portions of the herbicide in the original container and out of reach of children.
