How to Apply

The maximum number of broadcast applications of Preen Lawn Weed Control per site is 2 per year.

  • Mow lawn to normal height 1 to 2 days before applying Preen Lawn Weed Control.
  • Water lawn thoroughly at least 1 day before application to sustain moisture until the next watering.
  • Apply Preen Lawn Weed Control when weeds are young and actively growing, preferably in the morning when dew is on the grass. If grass is not moist at time of application, sprinkle lightly with water to allow the granules to adhere and to remain on the leaf surface of the weeds.

Preen Lawn Weed Control cannot be applied to St. Augustine grass, Carpetgrass, or Dichondra, as injury would result to these types of turf/grasses. Additionally, this product cannot be applied to established turf (any variety) where clover is desirable, as it would harm the desirable clover.
